HOMES FOR REDBRIDGE

The Aim To refurbish 20 vacant dwellings of various ages and condition to higher sustainability levels than the current Decent Homes Standard

Why • Help establish a systematic approach to reducing carbon emissions.

• To support other sustainability objectives such as water efficiency, waste minimisation and materials.

• To assist the development of standards to measure the sustainability of housing refurbishment.

• To test ‘modelled’ v ‘actual’ performance.

Refurbishment works contractor

Employers Agent & Code assessors

Knowing the ‘real condition of our stock’ Pre and post refurbishment testing was carried out to all 20 properties including: • Air tightness testing • Thermal imaging • Spot measurements of Temperature, Relative Humidity and ventilation • Indoor Air Quality (Formaldehyde, Total Volatile Organic Compounds and Carbon

monoxide) • Water audit (tap and shower flows, WC types etc.)

• Additional pre refurbishment tests to some of the properties included ecology

assessments, flood risk assessments and sound insulation testing Individual reports were prepared for each property to assist with the desktop modelling

Achieving some of the code elements also informed the desktop modelling Nine elements of the code considered: • • • • •

Use of materials can affect carbon emissions Daylighting and overheating risk Use of renewables Lighting and appliances Water efficiency

• • • •

Site waste management Ecology Sound insulation Flood risk

The Results How the homes measure up

Ten of the properties were refurbished to high levels of carbon reduction ranging from 62% to 82%.

Improvements in carbon emissions

Ten of the properties were refurbished to Decent Homes Plus standard, resulting in carbon emissions ranging from 7% to 44%.

How the homes measure up

Ten properties achieved CSH Level 3 equivalent water efficiency 105 litres per person per day.

Improvements in water efficiency

The ten Decent Homes Plus standard homes achieved CSH Level 1 equivalent water efficiency – 120 litres per person per day.

How do the homes measure up against new build performance?

The Code for Sustainable Homes only applies to new homes built on or after 1st April 2007. However the vast majority of the UK’s 26 million homes have been built before this period. Although not strictly comparable, the project group were able to calculate the existing carbon emissions of the 20 properties, which all fell around the -1 to -6 scale compared to new build carbon emissions.

For instance, Freshwell Avenue’s existing carbon emission prior to refurbishment was 8979Kg of carbon per annum. After it had received minor environmental improvements its carbon emissions were reduced to 5000 kg per annum. Brian Road’s existing carbon emissions were 8328 kg per annum, reducing to under 1500 kg per annum after it had received enhanced environmental measures; a large jump from -5 to +1; and roughly equivalent to Code for Sustainable Homes level 1 for carbon emissions.

New Build Code for Sustainable Homes

The existing stock has varying starting points and optimal levels by house type

What this means to residents Warmer Homes Healthier Homes Reduced risk of fuel poverty Money saved on fuel bills For instance 19 Charlbury Gardens met a 78% reduction in carbon. An estimated saving of £1,036 per year on fuel bills.

This figure does not take into account benefits from the new ‘Feed in Tariff’

Project Funding Total Costs Total Scheme Cost = £5million

Total works costs = £700,000 (Approx £35K budget available per property)

Lessons Learned Practical considerations?

18.5°C 18

Replicability - These properties were vacant!

Need to consider what is feasible in occupied properties to avoid decant process

16 SP01

14 12

Ensure ‘greener’ items are ‘Fit for purpose’ Waste water heat recovery units would not fit in the bathrooms

10 8.3°C

Specification changes & site workmanship can change your desired carbon targets Setting targets for improved air tightness allow for greater carbon savings SAP is based upon assumptions, (e.g. for occupancy numbers, levels of occupancy and weather factors) Pre and post testing is important to establish the ‘real’ condition and post refurbishment improvements made

• You can only achieve an 80% reduction in carbon through major works and at a significant cost above decent homes • Always start with fabric measures first

Some technology savings can not be claimed under SAP Consider the use of new technologies/materials as part of finalising your specifications Beware of assumptions around the property’s existing condition Where relevant consider active investigation of properties condition

• The existing condition of older homes means they perform at lower levels of the code

Wider sustainability issues have to be considered Consider other opportunities when refurbishing e.g. provision of recycling facilities in new kitchens, Site Waste Management Plans, improving sound insulation…

• Evidencing ‘real’ performance is important

Retrofit items may not always be practicable.

Beware if not replacing items, retrofit measures may not fit Balancing energy efficiency savings with Carbon emission savings Need to consider this in your choice of technology(s)

What are the next Steps?

To keep the show home for selected open days in April 2010

To study the energy and water performance of the properties post refurbishment and post occupation

GREENER YOU’RE INVITED

HOMES FOR REDBRIDGE

Supported by:

SHOW HOME OPEN DAYS April 2010

• To undertake post occupancy monitoring of whole house energy and water consumption.

• Study the affects of user behaviour on energy and water consumption.

• To disseminate the findings through a best practice publication containing more details on the costings and via dedicated web pages • To compare the results against our successful ‘Retrofit for the future’ carbon reduction projects
