| ACLAMO’s building, built in the 1920’s as a branch bank, in Norristown, Pennsylvania has no roof insulation and has single-glazed
and leaky windows and entry doors. Brian Billings Architects designed this comprehensive energy conservation project, which
will utilize part of the roof area of the building to install a 10 kilowatt solar photovoltaic array. The solar PV system will
generate more than 25% of ACLAMO’s electrical consumption. The project will also replace the old windows, add interior storms
to the plate glass windows on the historic façade, replace the leaky entry doors and add blown-in fiberglass insulation in the
roof. A new Cool Roof will further reduce cooling loads, in conjunction with the R-38 insulation.
Based upon our analysis of energy usage over the prior years, this project is expected to offset
more than 30% of total building energy usage.
