According to Brett Martin, rooflights can help to achieve reductions in CO2 emissions and aid Part L compliance. The company claims that a rooflight area of 15-20% provides energy savings in most buildings and the performance specification set for rooflights is an average insulation u-value of 2.2W/m?K. It believes the simplest way to achieve these energy savings is to install triple skin rooflights. Rooflights can be an effective way of introducing natural light into a building, reducing the need for artificial lighting and creating a more pleasant environment.

Research to investigate the effect that rooflights have on the amount of energy and C02 emissions, comissioned by the National Association of Rooflight Manufacturers (NARM), has found that rooflights save energy by reducing the need for artificial light and by providing passive solar gain. Undertaken by the Institute of Energy & Sustainable Development at Leicester's De Montfort University, the study shows that rooflights can have a dramatic effect on a building's total energy consumption. Bill Hawker, technical director at Brett Martin Daylight Systems claimed that anaylsis of the research suggests 15-20% is the optimum rooflight area required to provide significant energy savings.
