Pittsburgh, Pennsylvania - Bayer MaterialScience has conducted a life-cycle analysis of typical commercial buildings and found installing additional insulation during re-roofing can provide significant energy, environmental and financial benefits, the company said 12 May.
Bayer's report: "Energy and Environmental Impact Reduction Opportunities for Existing Buildings with Low-Slope Roofs," estimates the annual market opportunity for replacement covers 1.5 billion-sq.ft (139.3 million-sq.m) of floor space. BaySystems, part of BMS, is a leader in polyurethane insulation.
Low-slope roofs, the company said, are virtually flat with minor slope for draining. The company believes that improving thermal performance during the necessary re-roofing process, will save owners or operators of these buildings $2400 million in utility costs, save 0.266 Quads (quadrillion British thermal units) in source energy and prevent more than 19 million tons of CO2-equivelant emissions annually after a ten year period.
"The study is based on sophisticated energy modelling and includes and entire life-cycle perspective that uses rigorous evaluations to determine energy and environmental impacts," said George Pavlovich, product safety manager.
BMS said, across all buildings analysed, the energy saved by adding roof insulation during roof replacement is 20-28 times greater than the one-time energy required for making raw materials, manufacturing, installing and transporting the insulation "based on a very conservative 30-year product life."
