Buildings account for about 40% of energy consumption and 36% of CO2 emissions in Europe. The renovation of old buildings leads to significant energy savings: there can be about a 5% decrease in energy consumption and CO2 emissions. Therefore, the EU created the Energy Performance of Buildings Directive (EPBD), which promotes an improvement in buildings’ energy performance.

For an expert in wastewater collection and treatment in Belgium, one of our consultants specializes in adapting the clients’ buildings to fit the EU regulations. As the project leader in charge, he heads the renovation of buildings that are from the 1960s and 1970s.

The first phase of the project consists of renovating the roofs, as most of them are around 20 years old. Ample insulation is placed where needed and durable materials are used. In an effort to explore different options of materials and thickness of insulation, pilot-projects are set up in which our consultant can test different roofing materials. The positive effect of these new materials will only become visible in a few years’ time as thet have a long durability. Still, this is a big improvement as these new roofing materials are now part of the client database. This means that in the future, they will be able to compare, and modify their building specifications if the results of the recently used materials are positive.

Our consultant’s work consists of speaking with experts, planning the project scope, specifying quantities and making estimation of the costs, publishing through e-tendering, choosing contractors and managing the project until completion.
