Energy Ma*er Summit

-­‐ Performance Metrics, Standards and Conserva4on Poten4al -­‐

Norm Vezina York Catholic District School Board May 28, 2012

Energy Management Focus is on: Maximizing comfort in the environment when spaces are occupied based on established standards

Annual Energy ConservaHon Plan – Yearly conserva;on targets are set based on planned projects and ini;a;ves – Standards Used – Have to address all facets: – – –

Design & Construc;on Maintenance & Opera;ons Occupant Behaviour/Awareness

– Approved by Senior Admin

Design & ConstrucHon Several Sources for Standards –

OBC, ASHRAE, LEED, NECB

Other consideraHons – – – – –

Building and integrated systems need to be designed based on the needs, how it will be used and occupancy.

Maintenance and OperaHons • Keep all systems operaHng at peak performance – –

Preven;ve Maintenance Retro-­‐commissioning

• Clean Buildings = Clean Environment = Be*er Energy Performance • Minimize equipment downHme • Must keep up with technology • Building AutomaHon Systems – constant monitoring • Established standards such as Temperature SeVngs • Incorporate Best PracHces

Occupants Behaviour ALL about People!

– Need to create the awareness – Need to create the desire for people to

par;cipate – Need to share the results (metrics)

However, the benefits of awareness are…

Hard to see

Difficult to measure and analyse

To be successful…

Need the buy-­‐in from everyone

in the

organiza;on

Use established protocol to measure and confirm results

Must be able to support the metrics.

Provide regular repor;ng on progress and opportuni;es

Yearly Performance Metrics TradiHonal energy database:

– Involve transferring data from u;lity bills into a

U;lity Consump;on Database – Provides an excellent historical summary on how well you managed your energy (yearly report) – Data on invoice can be up to 3 months old – repor;ng takes more ;me – Hard to pinpoint specific issues or opportuni;es – Manual process – entry takes addi;onal ;me – Analysis is more generic and requires a good record of events/issues to explain variance

However…

• Historical data is very valuable but it does not indicate the result of your acHons in real-­‐Hme fashion • How do you know today’s acHons had a posiHve impact on conservaHon? • How big was the impact?

• Should it be done again?

• How much impact did a project have on energy?

• How large was the impact on energy following a change in the BAS system?

Real-­‐Time Performance Metrics • Real-­‐Time electricity data collected for Real-­‐Time energy management • For the energy manager, electricity demand in real Hme provides a host of informaHon that leads to performance improvements and bo*om line savings • Anomalies instantly show up

Using Real-Time data to - Create Awareness • Energy Champion Program was created • Real-­‐Hme data is displayed in graphical format for the last 24 hours • Shows electrical demand for the building • Demonstrates that occupant behaviour has an impact in a real Hme fashion • Save Energy signs installed –

Bring conservation leadership/successes to public attention

Energy Champion Program - Sharing the Results • Monitor is operated like a TV station including: • energy data (real time and historical) • news • posters (both programs and/or generated by student) • upcoming events • general conservation messages

Energy Management Results 2010 – 2011 results (electricity and natural gas)

YCDSB Average Energy Intensity:

58.5 MJ/c² (16.25 ekWh/c²)

– 5.5 % reduc;on over previous year (weather normalized) – 36.4 % reduc;on since the year 2000

Energy Management Results 2010 – 2011 results (electricity and natural gas) Total cost for schools = $8.31 mil – Lowest overall cost since 2005 ($8.39 mil) – Area increase of 20 % since 2005 – Commodity cost increase of 6.2% since 2005 – Cost/c2 just over year 2000 ($1.18 vs. $1.17)

Cost avoidance: $2.09 mil • Equivalent to providing energy for over 36 elementary schools • Over $15.55 mil accumulated cost avoidance since year 2000 – Equivalent to energy costs for all schools for almost 2 years

What’s next….

– Enhanced programming on the monitors – Crea;ng a “Conserva;on Challenge” in a real-­‐;me environment Buildings can challenge each other, in real-­‐;me, to a demand reduc;on duel – New Socware Program will draw from historical data, real-­‐ ;me data and BAS data (points) and compare to established metrics standards to iden;fy energy issues •

Ministry of EducaHon – UHlity ConsumpHon database (UCD)

Purpose

• To provide school boards with an energy management tool that will allow them to analyze the energy consumpHon of all faciliHes in their asset poroolio and establish comprehensive energy management strategies

Background • Launched in August 2009 • Off-­‐the-­‐shelf socware plaoorm • Currently collects data on electricity and natural gas accounts • only u;li;es that electronically provide consump;on data • system has the capacity to expand -­‐ water, propane and other hea;ng fuels • 24 months of historical consump;on data (where available) from first informa;on request • pre-­‐populated with applicable facility data from the Ministry’s School Facility Inventory System to provide meaningful analysis • building area • year of construc;on • Enrolment • collects consumpHon data from uHliHes on a daily basis

Ministry of EducaHon – UHlity ConsumpHon Database Current Status Number of faciliHes: 5,254 Number of meters: 11,433 Number of electricity accounts with data: 6,513 Number of natural gas accounts with data: 4,926 Number of Retail Sales Agreements (RSAs) in place with Local DistribuHon Companies (LDCs): • •

Ministry of EducaHon – UHlity ConsumpHon Database Key Takeaways The UCD is a valuable energy management tool for facility managers The UCD is one of the largest database of its kind in North America The educaHon sector will be able to comply with the Green Energy Act regulaHons through the use of reports in the UCD UCD is provided to all boards at no cost Each school board can have up to 5 users •

Each board determines who has access to their data
