The “2,000-Watt Sites” label certifies residential zones that are able to demonstrate the sustainable use of resources for the construction, operation and renovation of buildings and for the mobility associated with their operation. It is based on the “Energy City” label and the Swiss Engineers and Architects Association's “Energy Efficiency Path for Buildings”. For a housing development project, an application for a certificate may already be submitted at an early stage, and the label will then be issued after an assessment has been made of the project goals and the binding agreement governing compliance with the specified objectives.
