Highest Credentials for Bauder Sedum Green Roofs

The roofs on the offices for the Department for International Development (DfID) were failing, with water entering and damaging the fabric of the building; additionally the insulation was inadequate making the building thermally inefficient, contributing to unnecessary energy usage and needless CO2 emissions.

The overlayed Bauder roof solution, installed in 2010, incorporated the company’s integrated foil-faced PIR insulation and sedum vegetation blanket, making the project the largest retrofit green roof to date in Scotland. The rationale behind the green roof came about because in 2010, central Government offices were set a target to cut their greenhouse gas emissions by 10%.


The DfID monitored the performance of the newly installed roof and calculated the energy savings created as well as equating the reduction of CO2 emissions. The combination of the added PIR insulation and the additional thermal and environmental benefits of the green roof have led to a carbon reduction of 18 tonnes in the first year, and savings of between 3-10% in heating costs.

The project team included Miller Roofing as the installing company and Turner and Townsend Project Management, Mark Bruce, senior project manager said, "As Project Managers for the Department for International Development roof replacement project, we are pleased to confirm that the project was delivered on time and on budget; surpassing all quality expectations whilst incorporating many significant environmental benefits. The project team from Bauder and Miller Roofing were very professional and a pleasure to work with. I would have no hesitation in recommending them to any future clients who were considering a green roof system."
