Brill School Renewables Portfolio Introduction

|
A handful of County Councils have supported pioneering renewables work in their schools, thereby not only reducing CO2 emissions but also providing future generations with hands on experience and an understanding of renewable energy. Schools are also an effective way to reach communities with information about sustainable energy. Councils have a key role in facilitating renewable energy installations in schools. County councils can implement renewable energy projects in local authority run schools through their capital programmes. Where there is no direct relationship with the school, councils can still play an important role in supporting school-based projects. Schools can consider the use of renewable energy during new build, as a part of refurbishment or if an old boiler needs replacing. This case study looks at one school that has an ongoing commitment to renewable energy and its partnership with TV Energy, a sustainable energy NGO.

Context
|
Brill Church of England Combined School is one of a number of schools in Buckinghamshire which are members of the eco-schools scheme. Environmental awareness is integrated into the curriculum at Brill School and the school lists the educational reasons for developing its renewable energy portfolio as:
●
Opinions and values are formed at a very early age
●
We are a school and we educate pupils for life in all areas
●
We are a school and we are a source of education for the local community
●
We are renowned throughout the county within both the education and noneducation community as a school which is concerned about environmental and ecological issues
●
All schools would like to have more money ~ if we can spend a little to receive more in return ~ it must be worth doing
●
We share our ideas with anyone who is prepared to listen, a strength of our school is ICT ~ Computers and information technology ~ we are able to share our ideas and findings with a world wide audience
Brill school worked with TV Energy, as part of the Community Renewables Initiative (CRI) to add solar thermal collectors, and a wind turbine to its existing green energy measures, including solar PV panels.

Process/partners
|
Partners, Brill School, Buckinghamshire County Council, TV Energy. The head teacher informed local residents and parish councillors of the proposal to install the wind turbine as part of the consultation process. No negative feedback was received due, it was felt, to the turbine being mounted on only a nine metre mast. Indeed the community have been very supportive of the developments, both through financial assistance and through physical assistance with installing the turbine.
Technologies covered
|
Solar thermal water heating, Proven WT6000 wind turbine, PV solar and ground source heat pump.
Carbon savings, associated costs and savings

The solar thermal system is estimated to yield about 12- 13,000 kWh of energy annually. Payback is less than four years (£3,000 was the cost to Brill School for the system). This system, together with the energy efficiency improvements, has resulted in annual fuel cost savings of £1,000. Photo 2. The turbine attracts visitors from other schools wanting to follow Brill's example.
The wind turbine is expected to double the current electricity saving, assuming an offsetting of the entire annual energy output at 3.5p/kWh. Annual generation from the turbine will be between 15 and 25 MWh, comparing well with Proven's original estimate of 19 MWh given the area's average wind speed. The wind turbine is capable of producing in excess of £1,200 worth of electricity per annum (estimated annual energy yield 18,917.6 kWh).
The following funding was secured towards the installation of the solar thermal system and wind turbine: ●
The solar thermal system cost around £12,000.
●
£2,000 was awarded from the TV Energy Community Renewable Energy Grant.
●
£16,000 was secured from the DTI Clear Skies Grant scheme,
The remaining funding came from the school's own fund raising activities (£6,060) and from Buckinghamshire County Council Energy Challenge Fund (£8,060). The solar thermal system is used primarily to heat the school swimming pool over the summer and also provides hot water for kitchens during the rest of the year. This not only reduces environmental impacts from using fossil fuel, but has also enabled the pool to be used at a reduced cost to the school pupils and the wider community during holidays and outside of school hours. Out of season, the solar panels are used to heat water required in the kitchen. A Ground Source Heat Pump system has also had Clearskies funding, with the remainder coming from Buckinghamshire County Council.
Projects/spin offs

Brill School is an award winner for conservation and green issues and is used as a reference site for local schools up to a 30 mile radius. Pupils are well aware that many of the renewable energy sources they read about are working within their school, creating a better future for all. The school had already incorporated renewable generating technology in the form of PV panels (producing around 700 kWhs per annum) and energy saving devices before the solar water heating and wind energy systems. There have been many enquiries from across the country regarding the school and it has helped to give Buckinghamshire County Council the knowledge and desire to replicate this type of project.

TV Energy was contacted to assess the school's ideas on wind power and solar thermal systems, to advise on government funding, recommended companies, and promotion, plus general support. The head teacher played a key role, being the driving force behind the whole project liaising with suppliers, filling in grant applications, securing planning and arranging installation. TV Energy have helped to maximise the payments for electricity generated by the wind turbine in today's complex electricity trading market.
