The challenge

Solar PV
(case study 1)

The council has already utilised the available roof space on the building with a 90kwh solar system, the new heating system needs an additional 44kwh solar system to cover the extra electrical usage. The solution was to utilise the adjacent car park with the construction of a car park canopy to provide space for the additional panels. The cost of the installation is circa £1200 per kwh, greatly extending the payback period.

The site is located adjacent to a registered battlefield so there are sensitivities around the location and views from the battlefield.

Air to air heating system
(case study 2)

The original heating system was installed when the building was built in 1976, most of the system is now obsolete and exceeded is expected lifespan. The main challenge has been to design and program the installation of the system in a live building where critical services are required to operate, added to the challenge is due to the tight time scales for funding the system will be installed in the winter.
