On the occasion of Ecobuild 2012 exhibition to be held from March 20 to 22 in London, innovative technologies in the area of sustainable construction and environmental protection will be honored.

These include the use of renewable energy by photovoltaic systems. Considered a promising technology, power generation through solar energy is not limited only to new construction.

In England, Withington more specifically, the project reference to the sustainable renovation of existing historic house church “St. Michael and All Angels’ dating back almost 900 years which is the first “Zero-Carbon Church” in England. A photovoltaic system composed of Kyocera solar modules installed on the roof of the church, provides renewable electricity and a wood biomass ecological boiler ensures environmental warmth.

The power of this building dating from the twelfth century is handled entirely by renewable energy. The 24 solar panels installed on the roof of the church generate a total return of 3.12 kWp.

In addition, their solid frames must withstand without failure the high stresses associated with extreme weather conditions. Thanks to a special system of scales, solar modules were installed on the historic building while respecting its aesthetic appeal and without damaging the existing architecture. The renovation of the church is part of a sustainable concept, both in terms of ecologically and economically. Apart from installing solar, biomass wood boiler was also installed to provide heating.

For members of the parish, the renovation of the church is doubly paid: in addition to savings in CO2, generating heat and electricity is also reflected in significant financial savings. In England, this pioneering project will serve as a benchmark for sustainable renovation of other churches.
