To help inspire you, here are some energy exemplar projects both large and small from around Wiltshire:
This hall was built to replace the old hall in the village in 2007. The parish was able to fundraise enough to build an exemplar hall to meet the needs of the community and use renewable energy. The walls are render/brick/block cavity construction completely filled with insulation. Underfloor heating is served by a Ground Source Heating Pump (the first hall in county to use this system). All rooms have individual thermostat controls.
The hall is well used with up to 200 users per week and the hall could potentially overheat. There is a lot of glazing and these windows cannot always be opened due to the close proximity of houses (noise pollution). As a result of this, the hall has had chiller units and air conditioning installed to cool the hall space. This system has proved very reliable and the users are pleased with the level of heating in the winter. Lessons have been learnt with the glazing and ventilation. The main advantage is the low running costs.

This hall was built in 1886 and has had some improvements over the years. However users often complained about the poor facilities and, as a result the hall was losing custom. A phased programme of work has been carried out since 2011:
- new kitchen
- improvements to insulation
- new heating system
It was decided to have heating provided by an Air Source Heat Pump which serves two fan units in the ceiling and one compression pump outside. The system has been shown to provide sufficient heat for the hall from outside. An instant response by the system is more effective for a small hall which is used at different times of the day. Of course it is more carbon efficient, and in turn ensures that fuel bills are reduced. The community use has significantly improved.
This hall was built in the 1890s and is in the middle of a conservation area. An environmental audit was undertaken in 2010 and they have since carried out a range of measures to lower their carbon footprint:
Starting with the achievable measures -
- Thermostat lowered
- Monthly meter readings
- Hot water heating programme altered
Then the more expensive work was phased -
- Attic insulation
- Sash windows removed and draught proofed, double glazed as appropriate
- 2 external walls in the small meeting room and kitchen area were insulated using environmentally friendly materials allowing movement of moisture in this chilly area.
- Installed water meters in the upstairs flats
- Upgraded most of the downstairs light bulbs to LEDs
In conclusion: The Quakers and hall users are happy with the results as there is a more comfortable environment and the work has decreased the carbon footprint. This has resulted in greater usage of the hall.

This hall is a Victorian School that was converted in 1979. Users often complained about the poor facilities.
Initially an energy audit was carried out and £20,000 was raised supplemented by a legacy left specifically for the building.
The improvements included –
- new roof with 36 photo voltaic solar panels
- lowered ceilings with insulation
- low energy lighting
- new eco boiler and improved heating system
- complete toilet rebuild, automated water and lighting
The hall is running at about 95% capacity, and they estimate about 20,000 people each year use the hall and over 35 users groups. They are still able to keep the rental at £6.00 per hour and their income is above their expenditure. The expenditure for the PV panels will be paid off in 8 years, but these earn about £3K per year so it is a very good investment.
