Following an Energy Appraisal and Microgeneration Assessment Report in 2010, Winchester College invested in PV installations on five college roof top locations eighteen months ago which are already exceeding expectations. Their current focus is the installation of a wood pellet fired biomass boiler which they hope will serve the whole medieval heart of the College.

After receiving the report in 2010, a careful analysis of the campus was carried out and five roof top locations were selected that offered best generation potential, structural capability and minimal visual impact. At the southern end of the campus the chosen sites were Mill, the school's Design Technology building; the Works Department and the PE Centre, with arrays installed on both the sports hall and the pool hall.

At the heart of the campus, panels were installed on a flat roofed area of the classrooms where they sit behind a parapet invisible from ground level. Finally, New Hall was selected as part of its redevelopment programme. The final stages of that redevelopment are now underway and the PV panels will be joined by solar thermal panels provided to generate domestic hot water for the building.

Planning consent, and on some sites Listed Building consent, was required for the installations. Winchester City Council Planners were pleased to support the initiative and the consents were obtained without difficulty.

The installations were completed in late 2011-early 2012 and eighteen months the installations are exceeding expectations. 

Additionally a feasibility study was prepared to consider the prospect of hydro generation on Logie Stream as it passes through the campus however the scale of generation did not warrant the significant investment required.

The school's current focus is on the installation of a wood pellet fired biomass installation which is being constructed in conjunction with the redevelopment of New Hall. The boiler will serve New Hall and through a new district main will connect into existing boiler rooms serving the east side of the Ancient Buildings. The existing gas boilers in those locations will then provide back up to New Hall through the district main. In conjunction with other planned projects in the Ancient Buildings it is hoped soon to extend the district main so the whole medieval heart of the College may largely be served by the new biomass installation.

Winchester College continues to explore low carbon and energy efficient solutions as it maintains and plans the development of its facilities.
