New construction: Energy supply, resource use, and quality of living

Renewable energy systems are being used in select new construction projects. These include, for example, photovoltaic systems and heat pumps. Photovoltaic systems generate electricity from solar energy. Heat pumps use ambient heat to provide heating. The scope and use of these systems vary depending on the project.

When planning our new construction projects, we base our designs on the applicable legal energy efficiency requirements. In addition, we evaluate project-specific technical options designed to reduce energy consumption during the building’s subsequent operation, to the extent that this is technically feasible and economically justifiable. A building’s final energy performance depends in particular on the construction method, the design of the building envelope, the building services systems used, and the actual use of the building.

When planning construction projects, we assess – within the framework of the applicable planning and technical guidelines – how the available land can be used and whether it is possible, on a project-by-project basis, to limit the amount of permanently sealed land. The specific land-use adjustments implemented in each case depend, among other factors, on the location, zoning plan, open-space concept, and the technical and regulatory requirements of the respective project.

When selecting building materials, we take into account not only technical, functional, and economic requirements but also project-specific aspects of resource use. Depending on the construction project, factors such as durability, material usage, and/or the possibility of future reuse or recycling may be considered.

For select projects, we incorporate roof and facade greening systems designed specifically for each site. Depending on their design and maintenance, these systems can help provide shade for specific areas and alter the microclimate around the building, as well as provide habitats for certain plants and small animals. The actual effects vary by project.

In our projects, we take into account mobility options and infrastructure that can facilitate access to various modes of transportation. Depending on the location and project, these may include, for example, bicycle parking facilities, charging infrastructure, or good access to public transportation. The specific options available depend on the individual project.
