Monitoring
Socio-economics - resident surveys Logging temperature and electricity demand
profiles in 72 flats – half of which received energy advice
Still to analyse: Logging electricity supply to blocks Boilerhouse gas use CHP PV

Resident Surveys
Doorstep survey Before and “After” 2009 and 2011 Randomly selected sample of 79 (of 297 flats) 29 questions

Comfort

Comfort
•Can't keep flat a comfortable temperature as there is a problem with cooling - can't open the windows enough to get a breeze as there are still workmen outside and it is dusty.•Winter is better but summer is worse. Hard to ventilate during hot weather - bought two fans.•Problem with thermostat x 2•Heating not working

In Summary
More people are certain that they know less People are doing roughly the same or less about
it More people are happy with what they do Broadly in line with the national picture High level of satisfaction with the refurbishment
and thermal comfort standards

Behaviour Change
2 groups: test & control - Feb-June 2011 Both groups received logging equip (without
displays) – temp and electricity Test group received energy advice Identical distribution of bedrooms and total
occupants in each group Almost identical cooking fuels/appliances Similar distribution between 3 blocks (which are
identical except for height) 2 doorsteppers – one giving advice – one
installing meters – around 40mins per flat

Cost of Advice
£1,780 (excluding kit) £24 per flat Electricity saving 7,116kWh = 3.6tonnes CO2 Gas saving? 11tonnes CO2 No persistence £435 per tonne C 4 years £54 per tonne C

Conclusions
Controls need clear labelling/instructions Comfort temperatures are much higher than
generally assumed in modelling – implications for plant sizing
Energy advice seems to show a small effect on demand temperatures even in the absence of financial incentives and on electricity demand
This effect either decreases with time relatively quickly OR has a seasonal relationship
Cost effectiveness depends on persistence Huge scope for behaviour change in comfort
