FOREWORD by

DAVID MASON

Senior Sustainability Manager at Skanska

THE EMA MAGAZINE

Welcome... ... to the latest edition of The EMA Magazine. I was keen to take the opportunity to introduce this edition and emphasise the importance the EMA can play in knowledge sharing and our continued professional development.

As part of my role with Skanska I keep a close eye on new technologies, constantly looking for new solutions we can apply in the projects we build and the facilities we manage. This is an exciting role but comes with an ongoing need to expand my knowledge and for me, membership of the EMA is proving vital.

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

New technology is emerging at an ever increasing rate presenting fantastic opportunities for us energy managers, but with it comes challenge as it is usually our role to specify, select, design and implement these solutions sometimes pushing us from our comfort zone. This is where being able to draw on the collective knowledge of a wider network of likeminded professionals such as the membership of the EMA can add real value.

4

This edition is again packed with articles, interviews, knowledge and experience directly from our membership and I hope you find it interesting. But, I would also urge you to explore what else the EMA has to offer. You will find practical training, technology and buyer’s guides, members meetings, the EMA Energy Management Hub, targeted working groups and industry initiatives all designed to help you improve your knowledge, understanding and status as an energy manager.

Enjoy!

Energy Management at Landsec

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

In this regular feature, we focus on how organisations across different industries approach energy management. In this issue, we are exploring the world of property management with Charles Sainsbury, Energy Manager at Landsec.

As the largest commercial real estate company in the UK, Landsec takes the impact of its operations on the environment very seriously, while also recognising that the sustainable economy provides an opportunity to deliver economic savings to the customers and communities it serves. Managing a mixed-use portfolio of shopping centres, offices and leisure destinations worth £14.4bn and an annual energy bill of over £20m brings its challenges, but consuming natural resources efficiently is a key part of our sustainability strategy, with a view to both mitigating the risks presented by climate change and reducing operational costs for our customers. Delivering our active energy management programme ensures we do just that, which is important given our stakeholders told us that energy and carbon was one of the issues that mattered to them most.

What does energy management mean at Landsec?

Our buildings use a lot of energy, so reducing consumption is an integral part of managing the portfolio; be it through utilising natural ventilation at Bluewater Shopping Centre or optimising the heating plant at our Head Offices in London. Active energy management is one of our key tools in reducing our carbon emissions and we’ve set ambitious science based targets to drive performance. These targets mean

we have committed to reducing energy and carbon intensity by 40% by 2030, compared with 2013/14 levels. With a fluctuating portfolio, using an intensity metric of kWh per/ m2 is the best way to assess and compare the performance of our assets. We have made good progress to date reducing our energy intensity by 13.2% and our carbon intensity by 18.5%. Our approach to carbon reduction is three-fold: • Use less energy – fine-tuning our buildings for performance and upgrading assets. For example, we have implemented retrofit

property company to sign up to RE100.

Energy also represents a huge opportunity for us to be innovative and creative with the technologies we utilise at our properties.

Sustainable design and innovation is a key element of our strategy, and arguably our biggest opportunity to reduce our environmental impact – getting the right technologies at the design and construction phase is crucial in ensuring our assets perform efficiently from day one. We’ve installed some bold technologies at new developments, such as the first hydrogen fuel cell and a large ground source heat pump system in the City.

We’re seeing the benefits of these two, three and four years in to full operation through lower energy bills and RHI income.

How do Landsec deal with energy management?

lighting programmes in a number of our retail centres.

• On-site generation – maximising the opportunity for our assets to self-generate through low-carbon technologies and renewables – we’ve committed to increase our portfolio of renewables by setting a target of 3MW of installed capacity by 2030, which is an increase from our current 0.6 MW. New installations of solar panels at Trinity and White Rose shopping centres in Leeds will increase our capacity to 1.4 MW. • Procuring renewable energy – we are committed to always purchasing 100% renewable electricity and we were the first

We were rare amongst our peers in that we opted to go down the ISO 50001 route in order to comply with ESOS, but it was the obvious choice for us as it complemented our existing environmental management system.

We’re now reaping the rewards of this approach, systematically managing energy, which embeds auditing as a ‘business as usual’ activity, allowing us to continually identify opportunities to reduce energy consumption. For us, this was clearly the best way to drive ongoing performance across such a large and diverse multi-asset portfolio. Adopting a ‘plan, do, act, check’ approach has allowed for consistency across the company, empowering sites to implement their own innovative energy reduction initiatives. The Landsec Energy

• Analyse performance – we analyse and interpret a host of data points from our buildings to identify areas for improvement.

• Partnering with experts – we sit down with our service partners who are empowered to make strategy changes and incentivised to improve performance.

• Engaging our customers – ultimately, any improvements we make benefit our customers, so we continually update them on progress and seek to engage with them on initiatives they’d like to implement in their space.

• Action – finally we make decisive interventions to reduce energy at our properties to drive continual improvement using measurement and verification techniques to validate and report the benefits.

support their own sustainability objectives. To get things done you must be determined, be personable and adapt to your audience when trying to get buy-in for energy reduction projects. As energy professionals, often the key to this is being able to distill the technical case in to a meaningful business case, that is compelling to everyone regardless of knowledge level. In simple terms, partnership and collaboration is key and we challenge our service partners to move away from the typical client/customer It’s not just technical interventions relationship – working in true partnership allows ambitions that will help us achieve to be aligned and targets to be achieved. our targets – our people are

“

In simple terms, the implementation of our EMS is assured by site specific Energy Reduction Plans and we are committed to ensuring every asset has a plan to reduce consumption. We carried out in depth assessments at our highest consuming properties to identify a number of energy saving opportunities that will make inroads to our ambitious targets.

In London, across our commercial offices we have focussed on clever, quick-win, fine tuning strategies such as free cooling and heating plant temperature glides. In retail, across our shopping centres we have much greater opportunity for true ‘spend to save’ measures and we are implementing a number of exciting projects such as retrofitting solar PV, as well as a number of LED lighting upgrades. There is ‘no one size fits all’ solution across the portfolio, as each property is different. However, we now have a firm idea on what reduction strategies will work at our assets.

It’s not just technical interventions that will help us achieve our targets – our people are critical in delivering our energy management system on the ground. To build resilience and sustainability skills

across the business, we delivered a comprehensive training programme last year called Sustainability Matters.

The programme focussed on role specific modules to enhance the diverse range of skillsets and professions we have at Landsec. I delivered elements of our Efficient Operations module on how to measure and optimise the operational performance of our buildings and how to set energy and waste reduction strategies. It was highly rewarding to deliver the training and on average, across all of the modules delivered, participants increased their knowledge by 40%.

In-house training is hugely important in giving our staff the knowledge and

skills to embed sustainability in their day to day roles. Attending the level 2 modules is mandatory for key roles across asset, development, project management, engineering and operations teams.

What areas of every day’s business at Landsec are most challenging in terms of energy management?

One of the most challenging yet exciting aspects of our industry is engaging the range of stakeholders that are involved in property management. This is particularly the case in a landlord occupier setting, where there are often multiple service providers delivering M&E to both parties. Our energy and carbon targets include our occupier’s energy use - this is a key point of differentiation between Landsec and other organisations - so we realised we must engage our customers to

Another constant challenge for us is managing data – we look after complex buildings with multiple data sources and thousands of meter points!

Fortunately, in order to manage this, we have our own in house Energy Bureau to manage our data streams, billing and procurement.

This removes a lot of the risk associated with outsourced or third party solutions, meaning we have direct control of our data sources.

We share reports with our internal teams and our service partners to constantly monitor and improve building performance – as any energy manager will testify, data is useless unless it is acted upon!

Top Tips on Strategies for an Energy Efficient Building

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

Between my current role as energy manager for BAM FM Ltd and through a variety of positions previously held within the Marks and Spencer energy team, I have been involved in ensuring buildings are running as efficiently as possible for the last 10 years. During this time I have been extremely lucky to have been part of some fantastic teams littered with passionate and dedicated people and have helped to achieve some fantastic milestones along the way.

8

Like all of you I have encountered many challenges during my journey; be them financial, behavioural, technological and so on. Consequently, without looking for particularly long you will always be able to find a list of reasons not to undertake efficiency measures. Moreover, we are all also guilty of feeling that the obstacles in our path put us in a more difficult position than our peers but in reality every building has its own set of unique problems to overcome.

In addition, buildings are becoming “smarter”, more sophisticated and are able to provide more data than ever before. It is easy to sometimes feel overwhelmed or tempted to be over ambitious and fall before you really begin.

However, no matter the complexity I firmly believe that every energy efficiency journey should begin with the same few simple steps giving you

the solid foundation from which to build upon.

immediately apparent and you can start to calculate the size of the prize.

1. Understand For me, understanding how, when and why energy is used within your building should be the first thing on every energy managers’ to-do list.

Only then will you be in pole position to decide what, why and who you can target to promote efficiencies.

Will energy efficiency strategies need to be passive or will building users have time and the desire to take part? Is anything out of bounds and too risky to tinker with or are you free to target all areas? Are certain times of the day likely to yield greater benefits?

2. Analyse Once the building is understood, next on the list should be analysing whatever energy data is available and more importantly what can be learned from it. If only billing data is available, does your consumption rise and fall appropriately in heating and cooling seasons? If you have access to more detailed information, does your energy profile tie in with your building’s occupancy? If you look after an estate, is it possible to find a commonality between buildings to compare and benchmark – looking for anomalies both good and bad?

Do you require more information to develop energy efficiency strategies? AMR to replace manual readings perhaps or sub-metering to capture specific areas or processes?

When do you use energy and how do you pay for it?

Do you pay peak demand charges, if so could these be offset by either altering existing control methods or utilising any site generation? Could on site generation by utilised in a smarter way? Is energy storage or demand response viable for your portfolio?

Without fully understanding your building’s energy flows, efficiency strategies are likely to be flawed.

For example, installing inadequate lighting for building use may mean money wasted in rectifying; implementing a strict temperature regime may result in users overriding equipment and circumventing policy in rebellion. Once a building’s purpose is fully understood potential efficiencies should become

3. Target Following this, it is time to set some achievable goals. Often energy targets are arbitrarily set without any real consideration to what is achievable. Numbers like 10%, 20% or even 50% might sound great or tie

VMUC-EM makes energy monitoring simpler VMU-C EM: A new integrated wired or wireless web-server solution The VMUC-EM collects data from up to 32 energy meters and temperature inputs and exposes the data to local networks or the internet via one of its three web services: (FTP) file transfer protocol server, which enables data to be pushed to a capable BMS, server or cloud-based service provider on a scheduled basis; HTTP client that allows data to be pulled on demand; or a Web server providing always-on access to real-time data, trending and alarms.

• Integrated modular local monitoring system for Energy Management plants based on Webserver and FTP/push capability • Logged instantaneous variables of each meter can be displayed on daily, monthly or annual basis • Easy to read GUI displays the entire installations energy consumption • Alarms and events, visual, SMS & e-mail • A fully scalable solution • Integrated license free software

in with other business goals but are they achievable? Before concluding target setting there are a number of things to consider including; what has been achieved before; what is your current spend; do you have any capital; how efficient is your current building or estate? Target setting should also be made in collaboration with all relevant stakeholders with future business plans firmly in mind, for example, is the business looking to expand? Finally, what target style would best suit your organisation’s goals? Are you primarily interested in the sustainability angle and looking at a simple kWh or CO2 reduction or is cost reduction the principle focus?

Each target type will have long and lasting implications on what kinds of efficiency measures will ultimately yield the greatest benefit.

4. Change Focus energy efficiency measures on existing equipment, maintenance and behavioural change first, before spending big on things like increased control or renewables. Often these yield the best returns on investment with very low initial outlays. A state

of the art BMS controlling a HVAC system riddled with holes and leaks is still going to be inefficient. A new PV system may be a good photo op but if the T12 lights inside are still burning 24 hours a day unnecessarily, then is this really the best use of time and money?

Often viewed as a hindrance to energy managers, don’t overlook what could be your biggest asset in reducing consumption - the buildings’ users. Everyone has a vested interest in energy; they often just don’t know it yet! It’s the energy manager’s responsibility to find out how to interest all members in the organisation in promoting efficiencies. Some will react to the sustainability benefits and green credentials, others to reduced maintenance associations or improved working environments, others will purely be interested in the financial benefits, maybe some may be motivated by competition; building vs building, floor vs floor.

There is always an engagement avenue open.

5. Collaborate Many energy managers do not have the luxury of a budget, and if they do it never quite seems to be enough. Is collaboration an option? The chances are that you might not have enough money to replace a boiler system ahead of its perceived lifespan, but when the time comes can you sway the maintenance department to plump for the most efficient model available? This could be achieved either through a convincing argument on how it will reduce maintenance or increase efficiencies.

Alternatively and even better, can the energy department part fund the project to ensure the best fit for all parties? Finally, when a new building is being designed, could you get involved to ensure that a holistic view is taken to services installed, running costs and systems deployed?

6.Verify Make sure you can prove the savings you make, and make sure everyone knows about it!!!

A Six Step Approach to Energy Management in Buildings

10

I was brought into the organisation about 2.5 years ago to report on energy usage and reduce where possible. The first step of the process was for me to gather as much information as I could about the portfolio which consists of approximately 100 buildings spread across the U.K. The Science and Technology Facilities Council (STFC) has 5 main sites, located in Abingdon, Didcot, Chilbolton, Warrington and Edinburgh and an annual energy budget of approx. £12 million. All five sites serve different purposes and have holistically grown over time to support the scientific research which is conducted by our world leading scientists.

1. Understanding buildings – construction type/use etc.

To say STFC has a unique portfolio may be an understatement. Our oldest buildings (in Edinburgh) date back to 1896 and to this day the sites are still expanding with construction of the Higgs Building (of Higgs Boson fame) in Edinburgh and the new RAL

(Rutherford Appleton Laboratory) Space building at the main site just outside of Didcot, Oxfordshire to name but a few. So the portfolio is greatly varied and comprises of: • • • • •

Further education facilities Hotels Restaurants Office Accommodation Small Scale Scientific Experimental areas (for example, clean rooms) • Medium Scale Scientific Experimental areas (for example, laser labs) • Large Scale Scientific Experimental areas (for example, a synchrotron – particle accelerator) With the diversity and scale of this organisation, we are by default a large user of electricity – last year for example we used 138,400 mWh of electricity across the portfolio. We have now collected key information to help us manage the portfolio and plan for the future. This information includes: • The portfolio of STFC buildings • When they were built

• How they were built • The area of these buildings (and separate areas down to room level within the building) • Who uses these buildings • In general, how they are used and who by The above forms the basis of the living document that is the STFC Energy Strategy. The occupants and assets are as varied as the buildings themselves ranging from ‘The Crawford Collection’ (a selection of documents and artefacts in Edinburgh from great scholars such as Copernicus and Galileo as well as a Victorian copy of Sir Isaac Newton’s death mask) to Petawatt (1 billion watt) lasers.

2. Collecting and understanding the general consumption data – kWh usage at high level and techniques to use when this is where the data ends In an ideal world every building would have a single gas, electricity and water meter serving only the building in question and all rooms and experiments would be

submetered to the ‘nth’ degree. However, as mentioned the sites have grown organically over the last 100 or so years so things are not as simple as they may appear.

buildings in the portfolio which have a sole gas and electrical supply, which have fiscal meters. These buildings act as our baseline for future development.

Serving our 100 or so buildings we have a grand total of 12 half hourly electricity meters, 5 small scale non half hourly meters and approx. 15 main gas meters. Each site has its own water supply, with most benefiting from a few water meters (to confuse matters slightly).

The first step for me as National Energy Manager (and one of my key requirements for Energy Management) was to have AMR (Automatic Meter Readers) installed on all fiscal meters.

3. Understanding and planning of further consumption information – sub metering at building level and what can be done with this?

This has helped in a number of ways to achieve: Financial control of invoices High level data analysis Identification of wastage Profiling of the portfolio

“

The AMRs have now been installed for over 12 months which means STFC now has a data set to work with which is great. Unfortunately for STFC, and for many other organisations, this is where the data story ends. There is still value in analysing the available data; some of the great benefits we have had are:

• A level of understanding around the out of hour usage • Some key data to base business cases on – leading to energy efficiency being brought to the forefront of the organisation • ASC (Available Supply Capacity) analysis – potential of cost saving • Data for degree day analysis • A ‘kWh/m2’ figure which we can base calculations on The last point above is both a blessing and a curse. We have two

Sub metering at a building level. The ‘golden goose’, the gift that keeps on giving, at least this is what I hope for STFC. Sub metering at a building (or beyond) level is the ideal scenario for anyone involved in Energy Management. In the world of Energy, data is king! However when trying to get sub metering installed on a large

Certainly the plan for the sub metering system (when operational) is: • To develop profiles and baselines for each individual building • Use the data to target out of hour wastage • Use the data to build in depth business cases for energy efficiency measures • Develop league tables to have each building trying to compete to be the most efficient 4. Reviewing, expanding and understanding through BMS So how did STFC piece together a business case for a full sub metering solution? Well STFC also has separate BMS systems running at all different sites and thus no one platform to view key information on (can be done at site level). With a cohesive line of thinking from an energy, operational and maintenance stand point an open protocol system was selected to collect all information from all BMS’s onto one platform which could be monitored by our helpdesk staff.

This open protocol system will provide a dashboard for each of the buildings from an energy standpoint but also from an asset monitoring standpoint.

The thought process is that this will lead to cost savings in Energy and also in maintenance costs as each asset is monitored and alarmed so any issues will be flagged prior to them becoming a major concern.

Sub metering at a building (or beyond) level is the ideal scenario for anyone involved in Energy Management. In the world of Energy, data is king!

”

and complex portfolio there is a large stumbling block – the capital cost and the forever question payback or ROI. Now for STFC (and my role), based on the analysis of the available half hourly AMR data, sub metering was a must, however it is still extremely difficult to prove a payback without the granularity of the data – which is delivered by sub metering. A never ending debate, however STFC have progressed the idea and are mere weeks away from having a fully operational sub metering system – at a building level.

At present, the simple tasks performed using the BMS were: • A review of the current sub metering capabilities (which highlighted that yes there was some form of sub metering, however it was programmed to overwrite every day) • A review of the building set points (which should be primarily set at 19-21oC as per CIBSE

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

• • • •

The remaining buildings can have a kWh/m2 rate applied to them based on the information we do have about them, however this has to be adjusted and taken as a discussion point only as it is based on the area of the building. So while the biggest building in our portfolio does happen to be one of the most energy intensive (the particle accelerator), the second or third building may be a warehouse for storage. In which case the kWh/m2 rate has to be taken with a pinch of salt and manually adjusted based on experience.

Perhaps in time, a follow up piece will be done on how effective this has been.

guidance) • A review of the heating profile of the buildings The review of the current set up did highlight some issues, however once again any data is useful in the realms of energy management.

5. Improving and planning projects – from the simple to the complex – what we have in the pipeline Being one of seven research councils within the U.K. we at STFC are working on some truly fascinating things. These, by their very nature are energy intensive although ironically a lot of the research is looking in to the energy sources of the future.

We have examined multiple projects, and many are awaiting funding however the active projects we do have are: • Full sub-metering solution and asset monitoring system • 30kW PV install with 50kW Battery Storage system • Boiler/Chiller replacements • Demand Side Response G59 upgrades

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

The first project on this list will hopefully lead to many more projects, and for me it is the key

12

project moving forward as it will inform all future decisions.

I am looking forward to the trial of the battery storage system as I truly believe that PV arrays with battery storage will play a key part in the Energy landscape moving forward.

6. Identifying and overcoming barriers Science. Comes. First. This is the mantra which runs through The Science and Technology and Facilities Council, and rightly so. There are hundreds of ground breaking experiments going on across all of the sites in the fields of: • Lasers & Plasma Physics • Astronomy and Space Science • Particle Physics and Particle Astrophysics • Energy (Laser Fusion, Hydrogen Storage, Fuel Cells) • Environment • Medicine, Health & Bio Science • Chemistry • Physics and material science • Engineering & enabling technologies • Accelerator science • Computational science Working with so many highly skilled individuals drives the need for accurate business cases even in the earliest stage of discussion.

Scientists by nature question everything and are obviously very protective of their working environments and equipment (again rightly so, a lot of the equipment is custom built to very exact specifications).

This makes the project timeline for anything STFC tries to accomplish somewhat extended.

This means that when projects do begin STFC is hopefully getting exactly what is required with no negative outcomes.

Some of the barriers I have had to try and

overcome so far are: • When attempting to install a PV array and battery storage solution on site scientists were concerned over the impact of the invertors on the equipment – a solution was to install the invertors in a faraday cage to eliminate certain risks. Further concerns were discussed surrounding the reflection from the PV array on readings taken by the satellite at this site. Unfortunately, due to time constraints, STFC had to move the project to another site, although when this is operational we fully intend allowing our scientists to run experiments to satisfy any concerns.

• As part of my interview with STFC I commented on the lack of visible renewables. At the interview I was told that wind turbines could not be installed due to the vibrations interfering with laser experiments on site.

I have yet to challenge this statement as no formal report was written, however we are in the process of adding more renewables to the portfolio.

• Voltage Optimisation. We have been working on installing voltage optimisation for some time, however due to the sensitive nature (age – some of the scientific equipment i.e. the syncatron is 1960’s technology and size/scale of 4-5 mW base load) the feasibility stage of the project is still on going.

Author’s profile: Following graduation Craig worked as a Quantity Survey for approx.

6 months before making the shift in to energy. His first energy role was as an Energy Technician within the third largest Local Authority in Scotland. The role involved managing a portfolio of thousands of accounts and an energy spend of approx. £10 million per annum. After two years of making substantial savings from mainly desk top studies (limited capital budget) he joined the Science and Technology Facilities Council as the National Energy Manager.

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

My introduction to BMS optimisation

14

Significant savings can be made via optimisation of a building controls system, up to 20% electric and 50% gas is typical for very poorly controlled buildings. My background started in controls over 20 years ago and more recently as a controls consultant and energy manager.

My first job in controls mostly involved trouble shooting and fixing communications networks; as I progressed I started to correct strategy but it was never really about energy, it was about making it meet a specification or an often misguided client requirement. During this part of my career I never really had much understanding of plant function or HVAC design intent. My ‘light on the road to Damascus’ moment came during a BMS upgrade project where we started to look into some of the data surrounding the boiler plant operation. We noted that boiler stages appeared to be firing without having much effect on flow temperature. The plant in question was controlling a number of variable temperature circuits which happened to have historic logging configured on the control valve outputs. The

simple step we took was to override 2 out of 3 of the boiler stages, this had the effect of producing a lower but more stable flow temperature, but accidentally all the control valves operation went from a mode where they were modulating gently to a mode where they were perfectly stable. At this point, I realised that with better knowledge of building service design I would be able to write better control strategy that would harmonise not only the aspect of the HVAC system but to also consider the building as a component in the jigsaw.

10 years on During the last 10 years I have carried out optimisation works on many buildings for many clients which will deliver 100’s of millions of pounds worth of sustained savings over the remainder of my life and beyond. My view on the BMS industry regarding energy efficiency is very poor, we are constantly reading about the latest box of tricks that is being sold but in my view the equipment we had 10 years ago can more than compete with the latest technology if managed, programmed and maintained correctly by competent

personnel. The current technology is designed to deliver enormous amount of operational data which we can use to make improvements, but unless we can fully understand the data and feedback the results into the engineering process then it will only ever remain as data, filling up a server somewhere.

Here are my thoughts on what to focus on – making savings simple When I hear others discussing optimisation I hear a lot about schedules, set points, dead-bands, and there is also a lot of talk about occupancy comfort. This is fine, all these steps will help towards the overall savings but in order to make the type of numbers that get me exited you need to consider the control strategy surrounding plant efficiency. Put simply, I can change some scheduling and save 50 KWh/ day; if I can make that same saving over every hour of operation then this number is going to be much larger.

When I survey a control system I am interested in three or four blocks of data, heating flow temperature, cooling flow temperature and

• Building scheduling. Does the building turn off at night and does this synchronize with the occupancy?

• System stability. Oscillation between maximum flow temperature and minimum flow temperature.

• Control temperatures appropriate to the outside ambient conditions.

• If the system already been optimised.

You can then look at the subsystems such as air handler units (AHUs) etc. Data mismatches on sensors will give you an indication of poor maintenance or poor control (a mismatch is the difference between what it is and what it should be). Once this process is complete then it should be possible to draw together an optimisation action plan and ordered approach where you start with the big wins and work your way down to the small ones.

Chillers and boilers

If we look at chillers and boilers there are some fundamental issues that we need to understand in order to make savings from these system.

Cooling and heating systems are sized to meet a maximum demand

requirement. For chillers this will be when the outside air temperatures are at 30 degrees (10 days a year), for boilers the maximum demand will be when the heating system fires up from cold on a Monday morning when the ambient is -5 degrees.

What this means is that we have systems that are sized to cope with extreme conditions which typically occur 20 days of the year, for the rest of the period we have more heating and more cooling than we actually need (a lot more). This leads to system stability issues which result in the ‘too hot too cold’ complaints that we are all too familiar with. Once we understand this, we can then implement some very simple control modification to address these issues.

Ambient hold off Ambient hold off is a means by which you can disable main plant such as chillers or boilers when the weather conditions permit. I was very sceptical of this control when I first came across it. Why would a building owner spend thousands of pounds on a sophisticated BMS system and then operate the main plant using a very basic thermostat approach?

The main issue that ‘ambient hold off’ deals with very well is plant maintenance. In a building with 200 fan coil units you can guarantee that roughly a third of these will have valves that are passing and therefore delivering energy where it is not needed, this is known as heating and cooling loses. As an example, if during an upper ambient temperature I have this quantity of heat escaping into the space then I have roughly 60 KW of heat which I now have to compensate for with cooling, therefore by turning off the heat I save 60 KW of heat energy and a further 60 KW of cooling energy. The other solution would be to carry out some maintenance but the costs attached to this are quite large and everyone in building FM

is trying to reduce costs so this gets left until the complaints become too frequent. By comparison the ambient control can be written into a typical strategy in about 30 minutes so the return on the investment can be measured in hours or days. With some buildings it’s possible to turn the chillers ‘off’ at 10 degrees, with others it may not be possible to turn them off at all. If this is the case it may be an indicator that parts of the mechanical services are not working properly ie. there are a lot of heating loses or it could be internal heat gain, either way an investigation should be carried out in order to understand why. For intermediate conditions it should be possible to operate at a lower boiler return temperatures which will give both gas savings and electric cooling savings.

System oscillation System oscillation is something we should take a lot more seriously than we do. If there is an oscillation at the main plant then this will result in local control that can also oscillate.

It is also possible to have a stable source and create system oscillation by changing the proportional and integral settings on the local control loops; this actually happens naturally as we go through all the seasons.

If we have enough oscillating local control units these will then create a system oscillation on the main control source such as chillers or boiler. Oscillation can generally be resolved by limiting the number of stages of a heating or cooling source such that the overall system has low gain (high stability). It is possible that by doing this you will identify parts of the building that are not controlled correctly and a local investigation should resolve the issue (either too hot or too cold, either one or the other but not both at the same time).

Mechanical Ventilation All medium to high spec buildings have some form of mechanical ventilation, either fixed volume or variable air volume, which is mostly seen on higher spec office buildings.

The main criteria surrounding the design of these systems is the one that allows them to provide

outside air temperature.

From a review of this data I can determine a number of other pieces of information.

15

the correct amounts of fresh air to maintain the correct air quality required by legislation. This means that if we look at a typical fixed volume building then the heating and cooling capabilities of the fan coil system will far exceed the duty of the heating and cooling batteries at the AHU (with variable air volume the AHU heating and cooling capabilities are much larger). Considering this, it is then misguided to over control the supply air set point of such an AHU as we could be interfering with the efforts of the local systems. When I first started investigating such controls across a number of buildings I witnessed a lot of different strategies.

Some strategies used outside compensation to adjust the supply air temperature, some used internal temperature. At best it’s a guess, at worst it’s possible to set up an oscillation between the supply temperature and the internal temperature. The approach I have used basically controls the supply air between high and low limits and then we open these up to make best available use of free cool conditions.

Volume control on these types of ventilation is limited because if you drop the supply volume there is a risk that you will not meet the design requirement for fresh air. Also, the saving in fan power may well be lost because of the loss of free cooling and therefore extra work is being carried out via mechanical cooling usually via the local terminal units.

Understanding the intent of the design There are some buildings which are a little more sophisticated than others and it is often the case that you will see plant that is clearly not used in the way it was designed.

In discussion with the incumbent engineers it is often the case that they will argue that the design is

wrong or the systems have never worked. In my experience, I find it is more the case that the problems have never been investigated by someone who understands all the aspects of the design i.e. energy, controls and mechanics, preferably at the same time. Poor commissioning and early hand over of a building into operational services are all too common situations widely accepted as the norm by resident engineers who deal with these problems on a

daily basis.

For example, there is a building in London which features chilled beams. They have the option to run in three different modes. a) Free cool for chilled beam circuit on days when ambient is lower than 7 degrees. b) Small chiller for medium chilled beam conditions when additional cooling is not required at the AHUs. c) Two larger main chillers for chilled beam and main AHUs to be operated during summer conditions.

The pipework allows the system to run in all three combinations but during all my visits the main chillers were running. During further investigation, it was found that the main AHUs were calling for dehumidification. This condition should not have been possible during the ambient conditions on the day of the visit. Furthermore, the low pressure hot water system was also at 84 degrees during a summer visit. It’s an all too common occurrence that the designer gets the blame when things don’t work the

way they should but my current view is that we assume that the designer was correct and then look at the system as a whole to determine why it is working incorrectly. The more complicated the software is the less likely it is to work.

Data analysis Last but not least, this is a very important aspect of understanding how controls function.

Nowadays, I have little regard about how the control strategy is written, how a system is working can be addressed from the status of the operational data output. If you go to a site where none of the control points are logged you can be sure that savings can be made as it is unlikely that anyone other than the BMS maintenance contractor knows what is going on. It’s also likely that the maintenance contractor has little interest in saving energy or giving advice on how energy can be saved. Data is vital and additional software can be used to provide plant condition reports or feedback into planned maintenance. If there is energy sub metering on site it should be possible to combine additional information such as condition reporting of chillers by providing information such as ambient v consumption scatter plot. On a more simplistic level, simple checking the chiller flow temperature against the scheduling will give you the simplest indication that something isn’t quite right.

The Difference in Performance between Design and the Building In-Use We have the ability to design good buildings and the knowledge to operate them in an effective and efficient manner – so why doesn’t it happen?

The cycle of Real estate asset management is shown in Figure 2.

The construction industry has in general been “designing for compliance” using software with “standardised driving conditions” – see below. We know how to build good performance buildings but the issue seems to be having the design feed through to performance-in-use1.

This has led to what has been termed the performance gap. In reality this has two components (Figure 1): • The compliance gap; and • Actual performance gap.

Figure 2: Real estate asset management cycle

A high-performing building generates maximum profit via: • High and continuous rental income • Low operating & maintenance cost • Low depreciation One of barriers to this being achieved is the split responsibilities which is demonstrated below in the so called “vicious circle of blame” (Figure 3) which affect the procurement of sustainable buildings in the rented office sector.

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

The overall gap has been estimated at between 200-450%2 of which the modellers estimate 50-70% is the compliance gap3 and can be solved with more realistic modelling mirroring the conditions in operation more closely. However, the underpinning reasons for the second and larger actual performance gap are generally unknown.

There is a lot of speculation and hypothesis but little investigation and hard evidence.

Why is this important?

Management of real estate investments aimed at maximising property value and return on investment4 via: • Effective risk management • Efficient property management • Identification and implementation of valuable improvements

Figure 3: Barrier to the procurement of sustainable offices

On a pure cost basis the operation energy or the energy used in using a building is up to 50% of the operation costs or 40% of the total cost of a building (Figure 4).

Figure 4: The life costs of a building

If this is inflated by a multiple of 2 to 4.5 the cost to the end user is considerable. However, if the occupier is leasing these may just be passed onto them and they more not have much say in the management of the building. The effect on the asset and its value is just as dramatic with: • Deterioration of value • Service life of plant reduced • Fabric lifetime reduced • Costly remedial works to maintain value • In ‘void’ periods there is likely to be still further deterioration through lack of use • Loss of reputation Investigating the gap BRE have previously attempted to close the gap by using the Green Deal Tool to map Energy Performance Certificates (EPCs) onto Meters readings5,6; although this approach has merit the sliding energy management scale has little underpinning research to support the assumptions and no verification has been carried out to support these judgement calls by expert groups.

Anecdotal evidence from the asset management industry has indicated a number of possible reasons: • Issues with the management structure and governance; • Lack of maintenance due to resource and skills shortage; • Limited data; • Lack of practical solutions and their costs.

However, the real truth is nobody knows and this present an opportunity for whoever finds the evidence for the underpinning causes and then presents practical solutions to solve them. This has been recognised by the construction industry and priorities that were fed back from the UK Green Building Council Delivering Building Performance task group; the UK Innovate building performance project and a Building Services Research and Information Association workshop on Building Performance were: • There was data on the performance gap but no

systematic investigation of the reasons why and the magnitude of the issues – what was needed was a controlled study to investigate this; not attempting to link datasets • Design was not an issue but operation and the associated issues seemed to be the cause, however there is only anecdotal evidence to support this. A study is needed to codify and quantify the causes of poor performance in use • The “gap” seems to increase with time, again anecdotal evidence is available with no quantification of the underlying reasons; with a long term study needed to identify, qualify and quantify any affect • Health and wellbeing is associated with this effect but, as before, there is not true quantification, model or tool; as a result, a monetary value cannot be assigned to the loss/gain of productivity leading to an incomplete business case. A desk study is needed to identify knowledge gaps following by field study producing data leading to a model/tool for quantification of productivity loss/gains.

The main barrier to this is quality data from a large enough sample with full access to the building and their occupants. What was missing is “real-life” exemplars to investigate the actual causes of the performance gap and propose practical solutions. BRE have now been presented with that opportunity and Dr Andy Lewry is currently leading a two phase research project into the performance gap, which will be concluded at the end of 2018.

Author’s profiles Dr Andy Lewry is a chartered engineer, a chartered scientist, a Fellow of IOM3 and the Energy Managers Association; plus a Prince 2 and Agile qualified project manager. He has also authored and published best practice publications on energy management, energy audits, building control and building energy management systems. Recently he produced guidance on “Bridging the performance gap: Understanding predicted and actual energy use of buildings” and “Producing the business case for investment in energy efficiency”.

Lorna Hamilton leads on quantitative analysis aspects in BRE’s Social Research Team. She has experience of analysing and modelling a wide variety of data and specialises in the application of Generalised Linear Models for correlated data. She has worked with both large and complex data sets for a variety of Government, European Commission and commercially funded projects.

A range of technologies were seen as the most likely source of granular energy data to generate energy savings (Figure 3).

However, poor operational management undermines the aims of asset management and leads to: • Increased tenant complaints regarding comfort conditions and loss of reputation • Higher service charges • Longer void periods leading to a reduction of income • Lower and shorter rental values, as a consequence of high service charges and poor comfort conditions • Capital expenditure on HVAC equipment failures, due to poor maintenance • Tenants wanting to renegotiate rent values based on maintenance issues

CAREER & TRAINING by

PAUL BOREHAM

Independent Energy Management Consultant

Career in Energy Management The Energy Managers Association aims to encourage and enable more professionals to enter the world of energy management and environmental roles. Being an energy manager may not seem like the most obvious career for many. The EMA has taken on a challenge of changing the perception of energy management, by raising the sector’s profile and sharing its members’ – leading energy managers - insights into their career progress and achievements. In this issue, we have asked Paul Boreham about his career and views.

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

When did you first hear the term ‘energy management’?

20

When I started my career in electrical engineering, energy management was not commonly known as a separate role as it is today. This was partly due to the relatively low unit cost of energy, that was almost constant each year and that the duties of an energy management were usually incorporated into other engineering roles. This was around the time of privatisation in the 1990’s, when the Central Electricity Generating Board was being broken up into three separate companies, creating competition. The only organisations that warranted an Energy Manager at the time were major energy users, such as steel or chemical works, where energy costs were very significant.

Better control and understanding of systems, usually leads to efficiencies and often a consequential saving in energy and costs. This led to my interest and passion for the management of energy and the identification of waste through data analysis or audits.

I see that my career in energy management was a natural progression, driven by my early experiences, coming across many inefficient control systems.

As the energy supply industry was changing with privatisation and businesses needing to reduce costs, my career and the role of Energy Managers became important to many more companies.

How did you progress through the profession to your current role?

My various roles have been new learning challenges with different businesses covering different sectors from industrial, retail and property.

Each of these had specific energy requirements that needed to be managed and controlled.

Early in my career, energy costs were regarded as almost a fixed overhead, rising by RPI each year by many companies. This attitude encouraged systems consuming energy to be disregarded and have minimal monitoring. Identifying wasted energy through monitoring and analysis is a key skill for Energy Managers. During the time since privatisation, the energy sector has developed with new emerging companies and roles from risk management, energy trading, emissions trading, demand management, energy auditing, project management, corporate reporting and environmental management. As energy costs have risen and energy management has become more complex, Energy Managers have evolved from engineers, facility managers and financial managers to cover an ever-widening brief. To keep up with this evolution, regular training and a genuine interest in the subject is essential. This interest has driven my career from working as an engineer in a water company with an interest in control systems and electronics to managing millions of pounds of expenditure in different sectors from retail to property.

I have been involved in installing energy management systems as existing building management or control systems often only collected some engineering data such as temperatures and pressure but ignored fundamentals such as energy and power. Fortunately, this has now changed as the cost and relative importance of energy information has increased. The latest control systems collect and display energy data in easy to understand graphical displays. This information allows people to realise the importance of managing energy by highlighting issues or failures early.

The proliferation of web based products, offering instant control and monitoring from your phone should lead to fine control and the minimisation or elimination of waste.

It is easy to assume what is going wrong with a system due to the data but it is prudent to not jump to conclusions, until the evidence has become overwhelming. Above all, interest and drive to understand and resolve, are essential.

The subject of managing energy has become significant to many more businesses now as unit costs have risen and environment emissions are being reported and managed. Energy costs and carbon emissions need to be controlled. Controlling these costs can involve purchasing through contracts and employing hedging strategies to avoid the volatility of the market. Once energy has been purchased at the lowest rate, its use should be managed and monitored to ensure all waste is minimised. As a ESOS Lead Assessor, it is a concern that many companies still do not closely monitor energy.

Energy consuming equipment and processes need to be monitored, maintained and managed.

Identification of methods to reduce consumption, generate or manage the loads should be considered.

A good background of financial knowledge is useful for appreciation of projects and demonstrating their benefits.

Finally, in business today corporate reporting is essential so that shareholders, employees and customers can see that business is behaving responsibly. Energy production and the environmental burden it carries through its conversion is already a significant issue and businesses need to recognise this, report it and make plans to reduce. This reporting covers all areas of waste from energy, water, carbon and waste materials.

I consider that energy management covers all of these and can therefore provide careers in many different areas all related under the role of energy management.

Today, the role of Energy Manager is no less demanding and often incorporates environment and sustainability. Remote monitoring using web based meters can create vast amounts of data leading to just a monitoring and reporting role. Systems to collect, display and

analyse this data are crucial. The secrets and answers are contained in the data, if it can be manipulated and displayed quickly and easily.

We all complain about spreadsheets but data manipulation today is very easy with data being dragged into applications with ease. Once in an electronic form, it can be normalised, looking for exceptions and patterns.

Energy Management requires an element of detective work, where you suspect an issue, analyse the data, look for clues, and make a conclusion based on the data or evidence.

Finally, I have met and worked with many great people during my career as an Energy Manager and I hope that these people and companies do well with their careers or business in the future.

CAREER & TRAINING by

THE ENERGY MANAGERS ASSOCIATION

Enhancing Professionalism in Energy Management Energy managers do not have as straight forward career path as for example doctors or accountants, as most come from various fields such as engineering, surveying, maintenance, operational management, and even accounting. Many energy management professionals have picked up their knowledge from experience, learning from colleagues, magazines, on-line searches or networking.

The EMA runs the Knowledge and Skills Gap Analysis Interview to help you as an energy manager to pinpoint areas you may not have the knowledge base of. The Interview is a professional discussion with other energy management professionals touching upon your current areas of professional knowledge, whilst (at the same time) identifying any potential gaps, and suggesting ways to fill those gaps either through learning or mentoring. If interviewees demonstrate all the necessary knowledge during the interview they will be awarded the official EMA endorsement of the Recognised Energy Manager.

Energy & Waste Manager at McLaren Automotive Limited

In the Spotlight

When did you first hear the term ‘energy management’? And what did you think it meant then?

I first became aware of the term when I started pursuing post-graduate degrees in the Environmental field; it was quite new to me as I had always considered energy to be more or less a fixed cost to any business. I initially thought it was related to how a business manages the purchase of their energy needs, little did I know the extent to what the true meaning really was!

How did you become interested in energy management?

I have always felt passionate about the environment although I only really became aware of the climate challenges that affect us as a species on completion of my undergraduate studies in Mechanical Engineering and after a few years working in my previous role as a technical buyer.

It was only after I joined McLaren Automotive that I decided to pursue a career change and my employer was fully supportive when I notified

them of my desire to pursue part-time studies in this field.

What does your role at McLaren Automotive Limited entail?

Looking after all energy and waste management activities, from monitoring energy usage & optimising processes to implementing and managing new project installations.

What is the most exciting part of your job?

The most exciting part for me is when I am able to pick the fruits of my labour, so to speak. When I see positive actions as a result of behavioural change or once I’ve

However I like to look at these situations as potentially hidden opportunities!

Can you describe your typical day?

I arrive at work fairly early in the morning and will normally start by checking and adjusting BMS (Building Management System) settings for the day/weekend ahead, based on the prevailing/forecasted weather conditions, followed by a quick walk around the facility to check for any abnormalities to our normal production process settings and a quick chat with my production planning & maintenance teams.

When not in meetings, you will usually find me at my desk working on legislation documentation requirements, reporting, presentations, or generally following up on any of the many projects that are on-going at any given time.

What drives you?

implemented an activity or project with successful results - whether it leads to a direct reduction in energy consumption or in the amount of waste generated by the organisation – that excites me.

What is the most frustrating part of your job?

The most frustrating part of the job is when I see any unnecessary environmental harm taking place.

Reducing our impact on the climate in a way that is appropriate to people leading their lives; the thought that every kilogram of CO2 not emitted and every kilogram of waste that does not end up in landfill will have an impact on our planet and on future generations.

What qualities should a good energy manager possess?

I believe a good energy manager should take a holistic view to the role, as the job is fundamentally about minimising the environmental impact of an organisation whilst achieving

the fundamental business objectives.

To allow for this – and as an energy manager collaborates across all levels within an organisation and is meant to inspire – the key qualities one must demonstrate are leadership, communication, and presentation skills. You also need to be organised, innovative and ‘think outside the box’ when looking to overcome a challenge or come up with a new opportunity.

What is your greatest contribution to the energy management sector or your current role?

Considering I have only made the career change to Energy and Waste Management recently, I would have to say my biggest contribution has been my dissertation project – an energy management project on

The Future of Water — Time to Demand Innovation That is a nice bold title for you. However, predicting the future of the water sector has to be easier than being an economist or psephologist at the moment. But to make it even easier this article focusses on water technology and innovation rather than stuff like renationalisation or financing of infrastructure.

The water sector is terrible at innovation. It is second only to the construction industry in its lack of R&D spending. The general water company response to an innovative product or service is either, ‘well, we would like to trial this but you have just missed the budget allocation cycle’ or ‘if this is such a good idea why hasn’t anyone else done it before’ or just a simple ‘no’.

adoption of waterless urinals and early investigations of ultra-low-flush toilets.

But, the really massive opportunities lie in the interface between utilities, customers and data. The use of smart data and the internet of things should enable water companies to use sensors and automation to not only monitor but also control water systems from catchment to tap, and from the toilet and back. The water industry uses and produces water, heat, energy, phosphates, rare metals and more, yet it is late in recognising the potential of the circular

water and wastewater services are specific to the end user. This might sound outlandish but the One Park West development in Sydney is virtually off-grid and is supplying neighbouring offices. There are affordable and practical sensors on the market that can not only monitor water pressure, flow and quality for businesses and provide real-time information to mobile devices, but they can also learn water use patterns, detect anomalies and intervene to take remedial action.

What is Driving the Evolution of Energy Management in the UK?

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

Energy is one of the most significant costs for a business and reducing it by just a few percentage points can have a significant impact on profits.

Recent research however, seems to show a disconnect between the opportunities identified by energy decision makers and getting them signed off in the boardroom. CEOs typically have three key motivations – building shareholder value, sustainable business success and creating a legacy. By comparison, reducing the energy bill is often regarded as a deep operational issue and any investment required not looked upon favourably. We can all picture the charismatic Sales Director showing ambitious sales curves for increasing revenue and yet a similar contribution to profits by reducing energy spend is often overlooked.

28

To really highlight the opportunities here, consider that in order to pay their energy bills, Morrisons must sell two full shopping trolleys every second; Mitchells and Butlers must sell 7,200 pints an hour and Whitbread must sell over 400,000 hotel rooms each year. In the last example a 5% bill reduction is equivalent to running a small hotel at full occupancy!

A recent Telegraph/YouGov survey of senior managers and directors

revealed that 46% of senior managers had no idea what their company spends on energy and 54% of them had no idea who was responsible for their energy management.

Given that a fifth of the businesses surveyed spend more than £250,000

An added problem is that only 47% said that staff understood their energy policies.

What do you need to know about CHP? A Combined Heat and Power Plant seems too good to be true. Providing both electrical power and thermal energy from a single fuel source. Buy one get one free?

Let’s start with the basics of this tantalising energy offering. CHPs burn a fuel source to produce electricity and heat at the same time. They are usually powered by natural gas, which is most likely already being piped into your sites, and the provision of power and heat from a single source means there is a serious financial saving to be had compared to using grid supplied electricity from traditional generation.

On top of that, the CHP provides additional energy security to compliment your grid connection and emergency generators, diversifying your supply, as well as extending the life of your existing heating system, and lessening the need for oversized boilers.

As a form of on-site generation, you can also potentially export back to the grid for a few extra pennies when demand is low on site, or install off grid to provide heat and power to isolated installations or assets. Still not convinced, you can up the green credentials further by going for a biomass CHP, removing the fossil fuel element entirely.

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

And when it comes to the bigger picture, you would also be contributing to a decentralised energy network, improving the balance of supply and demand, relieving the pressure on grid, and making your business more sustainable.

30

So what’s the catch? Firstly, let’s understand how a CHP actually works.

this process and redistributed around the site to meet its heating requirements. There is also an opportunity to cool the site from this process, as the captured heat can be utilised by an absorption chiller, generating cooling during warmer periods.

Still no catch? A CHP doesn’t work everywhere.

One thing that makes a CHP installation viable is a constant heat demand. Whenever the unit is running it is producing excess heat, and without utilisation of this excess heat, the unit becomes far less effective.

So what do you do if you have no heat demand? Well, you can install an absorption chiller to generate cooling for the site. You can dump the heat outright, which limits the unit’s efficiency. Or you can turn the unit off altogether when there is no demand, scheduling the unit to run during the winter, and not in the summer.

But are you going to install an expensive CHP unit that will only run for 4 months of the year? Or dump the heat you are generating in the summer months, the very thing the CHP was designed not to do? This makes site selection imperative. There needs to be a suitable demand to ensure the unit is the right size and specification to function as best as it can. The best locations are often schools, hospitals, swimming pools, manufacturing, and hotels. All of which have a yearlong heating demand, and would also benefit from the extra energy security.

Taking up the offer

Traditionally, fossil fuel electricity generation works by burning a fuel source to release heat energy. This heat boils water, produces steam, and drives a turbine, which in turn drives a generator to produce electricity.

This process wastes energy in the form of heat at every turn, summarised perfectly by the iconic cooling towers scattered across the landscape put in place to cool this wasted heat.

In a CHP however, both electricity and heat are produced in a single containerised unit. Fuel is burnt in a gas engine to power a generator, which provides electricity to the building. Heat that would usually be wasted by this gas engine (as it is in traditional generation) is recovered from

So you have a good heat demand, your numbers stack up, and everyone is on board. However, installing a CHP can be a tricky process. Even small CHP units can be the size of a car, and a lot less manoeuvrable.

Trying to squeeze a MINI into a cramped basement plant room is always going to be a challenge, so it’s fortunate that CHPs come with an element of flexibility. Housing a CHP in a secure location outside the building it supplies, or on the roof if space and structure allows, are both viable options, providing the connections are available.

This also allows for easy access for servicing, and the installation of additional equipment such as heat dumps, or absorption chillers if the business case requires.

Tinytag Data Loggers:

Energy Efficiency Monitoring Things to look out for when planning your location, install, and specification • Planning Permission. If you can sneak the CHP into a plant room, this is not a problem. If you need to house it outside, or install additional flues that exceed the building’s current parameters, make sure a planning permission is secured BEFORE you begin works. You don’t want to wait 3 months after the install to get the local authority to sign it off.

• Noise. CHPs are much quieter than they used to be, but in a confined space filled with equipment, you may find yourself with an unwelcomed mechanical orchestra. Similarly, sensitive neighbours or customers/members/tenants may also notice the increased noise. Be confident that noise and vibrations are not going to cause issues down the line.

• Controls. The CHP not only needs to tie in with an existing BMS and any other forms of heat production on site, but it should also be preferred as the primary heat supply. You don’t want your boilers kicking in first thing in the morning only for the CHP to roll out of bed at midday.

• Building a relationship. This is vital. If you have separate contracts for BMS, boilers and FM providers, they all need to be on board, and understand what the system is trying to achieve. All of these providers will have their own contractual obligations to keep their systems operational, and will all need to contribute to ensure a smooth install.

Now comes the easy bit

The chances are that your onsite engineers or FM providers are not CHP experts. CHPs are fairly simple bits of kit, but combined with your existing infrastructure, they do lead to a more complex system, and require regular services and maintenance. If you do not establish an operation and maintenance (O&M) contract from the outset, and ensure this contract focuses on performance, you may have some difficult conversations when issues inevitably occur. Should the CHP cease to run without such a contract, your FM provider may refuse to touch it.

It’s not their install after all, and if you haven’t consulted them before delivery they may feel hard done by. Then your installer may drag their heels on call outs and services, as they are not incentivised to keep the unit operational. They were only contracted to install the CHP, it’s up to you to keep it running. All the while the CHP sits idle, and you have to explain why this project you fought so hard for isn’t delivering the savings.

How do you keep everyone happy?

• Performance Contract. Ensuring a performance based O&M contract is in place will limit this risk on you and your FM network, and incentivise the provider to keep the unit running and attend site regularly for services and fixes.

• Regular Stakeholder Review. The CHP should benefit everyone involved. Regular conversations to review the operation and performance allows for everyone

to engage and have their say. The CHP can then be adjusted when required to adapt to the needs of the building.

A stepping stone All in all, a CHP unit is a worthy investment, if it’s designed, installed, and managed correctly. The technology has been around for decades, and is globally utilised.

However, some would say that there is still a slight stigma attached, with too many units sitting idle in plant rooms due to poor choices during design and install. Some would also suggest that this is still a form of traditional energy generation, and distracts from investment in renewables. Although those points may hold some truth, I would argue that until renewables can challenge this established technology, CHPs are still the right stepping stone required to improve our energy security, diversity, and efficiency.

Owen’s current role with Prudential focuses on the corporate property estate, and the climate change impact of the wider business.

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

Sit back and let the savings roll in. If you have got your site selection spot on, sized the unit correctly, and got your controls right, you should have no problem. In theory, yes, but in practice, maybe not.

Commissioning CHP and District Energy — Birmingham New Street Station

Image by Ross Jukes Photography

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

Birmingham New Street Station is the first major station under Network Rail management to install a CHP plant and be connected to a district heating network as well as the first BREEAM ‘Very Good’ rated station.

32

The expansion of the new station concourse along with additional lighting, lifts, escalators and HVAC systems meant that Network Rail would need nearly double the amount of power than before to fulfil the requirements of stakeholders and improve connectivity around the station.

Exploration of various renewable and low carbon technologies was undertaken ranging from Ground Source Heat Pumps (GSHP), Biomass boilers, and Photovoltaic (PV) to cover 2,000 m2 around the south of the station façade. Using an existing city centre location meant many constraints excluded the use of some technologies such as Biomass and wind.

The Solution When PV’s were discounted due to the John Lewis development on the South Side removing the proposed PV area, Network Rail actively pursued the option of a Combined Heat & Power (CHP) scheme to provide the station with electricity from a 1.6 MWe gas fired turbine engine, connecting into the local district heating network to the north of the station. This ambitious scheme would reduce carbon emissions significantly when compared to traditional power station generated grid electricity, reduce transmission losses and use the by-product in

the form of heat that is normally lost in the cooling towers of old power stations. The preferred bidder, Engie, were also very keen to use the subterranean network beneath the station to supply the south of the city and avoid disruption around the city centre.

However, such an ambitious scheme was proposed part way through the detail design of a very complex £700M station refurbishment that promised the city minimal public disruption and no train operations disruption, whilst working within a highly governed rail environment.

The additional dilemma of using a CHP system for Network Rail was that the station demand profile was significantly more electricity intensive than heat. A heat partner was required to utilise surplus heat generated from the CHP plant and John Lewis was an ideal candidate being attached to the south of the station with its biggest store outside London.

With the inclusion of John Lewis agreeing to sign up to a heat agreement with Engie, a carefully

include for CHP or district heating due to the delay of incorporation into the project. As a result many design elements required retro fit to integrate the new scheme and source of power and heat.

Electrical integration and commissioning 11kV switchgear interlocking strategy, auto changeover philosophy, metering & intertripping requirements First, modelling was undertaken by Arup on the existing electrical system for both Load Flow and Short Circuit analysis to investigate potential issues that may arise on the existing network by retrofitting the proposed CHP plant. The study identified any technical constraints associated with options, considering the overall technical requirement of the CHP plant connecting to the installed electrical network.

The new station is supplied by two separate 4.5 MVA DNO supplies for resilience of a strategic station.

Affecting the power supply and operation of the station can have a potential consequential impact of 60% on the rest of the rail network.

The proposed operational scenario with CHP requires only one of the two incoming DNO feeders to be in

Arup, led by Engineer Kamal Siriwardhana, were commissioned to establish and test the safety interlocking requirements for the incomer 11kV circuit and interconnector circuit breakers on the switchboards at the station.

The interlocking scheme prevents paralleling the incoming supplies during the normal operation.

An automatic changeover scheme has been tested and commissioned to facilitate the change-over from one supply to the other.

Remote monitoring As part of the CHP Scheme, a remote monitoring philosophy for alarms and status indications of the 11kV switchgear and auxiliary systems located at the New Street Station 11kV switchrooms required designing and installing.

The New Street Station HV distribution network consists of two High Voltage Switchboards, HVSB-1 and HVSB-2, located in the Hinterland area of the station (Fig. 1). Each of the HVSBs is fed from one of the two supplies from the Western Power Distribution (WPD) network. HVSB-1 and HVSB-2 are interconnected through a HV cable. The new CHP plant is connected to switchboard HVSB-1 (Fig. 1).

Remote monitoring of the HV distribution network is achieved via the existing Building Management System (BMS).

The installation of the CHP engine, associated plantroom and pipework led to many engineering challenges to install a significant array of heavy pipework that runs from the south Hinterland up John Lewis and District heating integration along the station and commissioning roof to meet the Three new boilers were Engie network on installed at the station as Stephenson Street. part of the Phase 1 (2012) The connection redevelopment at the time to the wider CHP was being negotiated Birmingham’s and tendered. district energy network The heating to the station is interconnection Fig. 1.

Once key partners and an outline scheme were identified, the major challenges of finding a location for a proposed 1.6MWe engine and planning the pipework routes through the station and John Lewis without disrupting a complex programme of works around the station redevelopment was a huge challenge.

Identifying the location of the plant to satisfy The Clean Air Act and avoiding a large chimney stack to satisfy local planning were just two of the many obstacles the team have overcome in pursuing low carbon technologies.

These, and constrained site restrictions meant that the best solution was to locate the engine on the roof of the station.

LTHW demand. The lowest summer demand is when the heating circuits are off but domestic hot water is still required. This would result in high return temperatures when the heating demand is reduced. It is noted from Engie that the district heating return temperature should not exceed 65˚C. Therefore, lead consultants Atkins recommended to install a new primary pump to match the demand which is dealt with matching the actual station demand profile. A new 3 port valve and bypass linked to the return temperature was proposed to regulate the primary pump with the return temperature to the plate heat exchangers.

Roof Mounted Engine Due to the CHP plant being located on the roof of the existing 1960’s station structure because of the requirement of being in reasonable proximity to the flue, significant work and technical design was carried out on the existing structure to ensure the 18Ton weight of the engine

can be adhered over the life of the engine and beyond.

A unique challenge is to ensure that any vibration from the engine does not transfer into the Grand Central shopping Mall below. Consultants, Atkins, proposed special Neoprane anti-vibration mounts that are fixed onto the main columns of the station structure that would then connect to the steel frame that houses the engine to provide precise, low frequency vibration, acoustic and shock isolation. This is in addition to the acoustic enclosure of the engine and the array of anti-vibration spring mounts below the engine itself.

Results • Network Rail’s first ever CHP plant and district heating connection for a main train station.

What to Consider when Managing an Energy Budget

Budgets are normally prepared and approved prior to the budget period and should include forecast income, expenditure and capital to be employed against a particular cost centre, and should also take into account the company’s strategy, objectives and key performance measures. There is also no point in preparing a budget if it does not align with people’s behaviour, bearing in mind that a poorly designed budget can also actually damage performance rather than enhance it.

The following points should be taken into consideration Usually energy budget planning starts by developing an energy cost baseline that forms the foundation to build the budget up from. The planning and detail required for this exercise will vary amongst organisations, and unless one has

been asked to complete a zero-based budget (i.e. starting with a blank canvas), an Energy Manager will often begin by replicating the last 12 months actual cost. This early action is a good starting point, but can cause issues down the line if these figures are not scrutinised properly.

Figures may not reflect the correct or full cost for the period; for example: • Energy bills may be mistakenly allocated to other department cost codes • Not all energy bills may have been received, particularly where there are open disputes with the supplier, unbilled meters, or meters on quarterly billing cycles • Bills received and posted in the period, may actually cover consumption in a different period.

• There are outstanding reconciliations due, particularly where supplier contracts have clawbacks (usually for TNUos, RO & FiT charges) • Billing is based on estimated reads not reflective of actual usage • Bills have not been fully validated and contain errors that require either credit or debit rebills One should also consider any special or non-standard past events that significantly impacted consumption or billing. If historical data is being used to forecast future consumption/ cost, one needs to ensure that these one off events are omitted and replaced with “business as usual” figures so that the budget is normalised and remains realistic.

Examples of events that could be unplanned may include: machinery/ maintenance shutdowns, generator

use, new equipment or equipment upgrades, cold spells or heatwaves impacting aircons/electrical heating, refurbishment works, building closures, changes in activities or operational hours and so forth.

setting a budget can be an artform rarely perfected.

Energy review

”

If resources allow, an energy review can also be a useful exercise to support development of the baseline and can be undertaken either internally or by utilising an external consultancy. The energy review should offer an estimation of likely future consumption and cost based on an assessment of site equipment, building practices and operational cycles. A good energy review will also take account of additional variables such as degree day data, occupancy, floor space and processes etc., and should also define a usage profile.

Once a baseline cost is defined, impacts of any future variables can then be considered. Any known special events due to take place that could change energy consumption should also be documented and the impact calculated. It is prudent to engage with the senior stakeholders as well as to establish any potential plans for strategic change such as company growth, downsizing and activity or process changes that may impact consumption. It is also good practice to record reasoning and

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

As an Energy Manager, one will likely have responsibility for setting an annual energy budget. Given the variables and many unknowns associated with energy costs, and the fact that this expenditure is often not under the control of one department, setting a budget can be an artform rarely perfected. In reality, organisations do not always have a clear view of their budget position, and budgets are commonly a re-hash of historical figures. With energy costs continuing to increase year on year, this is becoming an increasingly significant area of concern for organisations.

methodologies behind all forecast assumptions, so that these can be referred back to, particularly if challenged.

Energy supplier rates

party costs (which are often bespoke to supply types and supply locations), and wholesale energy costs (which are often volatile and unpredictable).

Unless an energy manager has experience in calculating these costs, it is sometimes more sensible to enlist support with these estimations.

The organisation’s energy supplier or energy consultants should be able to help in providing direction on costs based on published charges and market intelligence they are privy to. However regardless of this,

One should also build in adjustments and buffers for energy supplier rate increases. There are different ways to forecast this cost and this will be largely dependent on the kind of energy contract entered into with the energy supplier.

If the company is One should also build in adjustments currently locked into a fixed fully inclusive and buffers for energy supplier rate contract, then quite increases. simply these contract rates can normally be calculated against the forecast consumption for each of the estimation around the wholesale relevant months up to the date that energy element of the cost will the contract expires. Where energy always require a higher element supplies are billed on multiple rates, of guesswork, and risk tolerances calculations may be more complex should be applied to these uncertain and consumption may need to proportions of the forecast. be split against these rates, or an average pence per unit price (APPU) can be applied.

the next year. Some initiatives can be implemented at little to no cost, however those requiring investment will likely need more substantial planning and some form of a presentation and business plan to project sponsors/stakeholders in order to secure funding.

Calculating likely payback from initiatives can take time, and it is therefore good practice to start this planning well in advance of the new financial year. It is also worth considering the source of funding within the company, and which money pot is more likely to pay out.

For example, if planning a smart meter roll out, all directly purchased meters will likely fall into a CAPEX request, however if there are restrictions on this funding, one could consider options to lease the meters which would then fall into an OPEX request. One could also consider requesting funding from different departments that may benefit from the proposed initiatives.

Incentives could also be broken down into mini projects over a longer term to help gain buy in on smaller requests, or equally performance contracts with third parties may also be an option to consider, alleviating the need to request funding completely.

When calculating the financial impact from energy efficiency initiatives, one should ensure that the return from these is forecast only in months that they will realistically be delivered within the budget year, as well as applying contingency to account for risk in delayed delivery. Risk ratings can be subjective and should be defined by the project manager. A RAG approach (red, amber, green) is common, and one can assume certain percentages of success against each traffic light and adjust figures accordingly. Individuals will have different approaches and perceptions of risk, and being a risk adverse, risk neutral or risk seeking individual will influence calculations. Despite this, there is still an essentially optimistic nature in people, that means

estimates and projects are often late in delivery and over budget.

ANNOUCEMENTS

BPMA 2017/18 Annual Report, Directory and Buyers Guide In October 2015, and in conjunction with the EMA, the British Pump Manufacturers Association (BPMA) produced a ‘buyer’s guide’ which was specifically formulated for Energy Managers, Facilities Managers, Estate Managers and Procurement Teams, to understand the substantial energy saving opportunities that replacing pumping systems represents.

THE EMA MAGAZINE • ISSUE JULY—AUGUST 2017

Pumps and their associated systems are major consumers of electrical energy. The ‘Energy

38

Savings Opportunity Scheme’ (ESOS) conducted by 10,000 large companies highlighted pumps as one the best potential energy savings measures.

To help energy managers understand the savings that could be made through upgrading pumping systems, and how to achieve them, a guide was produced to help ensure that the pump industry, and specifically BPMA member companies, were well represented when energy reduction strategies were identified and implemented, as part of any company-wide energy audit.

The buyer’s guide was distributed to all attendees at the EMEX event in London that year, which included a large proportion of the energy management community and was extremely well received.

It delivered on its aim of helping energy managers connect with those companies who were looking to manufacturers and suppliers

of pumps and related technologies for energy reduction solutions.

As a follow-up to that successful activity, and again in conjunction with the EMA, the BPMA is pleased to be able to distribute its 2017/18 Annual Report, Directory and Buyers Guide to all readers of the EMA Magazine. Providing unprecedented levels of technical, application and energy reduction data, it is hoped that this important reference material will help even more ‘non-pump experts’ to better evaluate and if necessary reduce the energy consumption of their pump systems.

The publication contains information about all BPMA activities and initiatives, details on the products and services offered by its members, along with a range of informative and practical articles.

Steve Schofield, Director and CEO of BPMA commented “We are thrilled to be able to issue this publication to EMA members as it further demonstrates our commitment to the drive for improved energy efficiencies across all pump systems, and to ensuring that all those individuals with responsibility for energy use reduction, have a core understanding of the impact that pumps can have on a company’s overall energy consumption. This undertaking also serves to put BPMA member companies, their products, their engineering skills and their business credentials at the heart of good energy efficiency practice. In essence, if energy managers need help and guidance with their pump systems, this Buyers Guide and the wider BPMA membership will provide that support.“
