Building performance

The performance of the base building tenants rent from is a crucial factor in the overall comfort and efficiency of the space. There are a number of ways to measure and influence building performance, through its Building Energy Efficiency Certificate (BEEC) and NABERS rating, Green Star rating and lighting power density. CitySwitch provides evidence of the benefits of high-performing buildings and sample calculations to assist with the business case for selecting a high-performing building.
