Purpose
Commissioning methods and tools are necessary to ensure that buildings reach their technical potential and operate energy-efficiently. However, documented commissioning methods are currently only available for some conventional HVAC systems and do not address the advanced systems and system combinations that are important for low energy buildings. Although the current focus of commissioning practice is to attempt to make buildings work as designed, significant additional energy savings can be achieved by commissioning to optimize building operation based on actual occupancy and use. This approach to "field optimization" of building HVAC systems considers the long-term persistence of savings and benefits achieved during the commissioning process.
The goal of IEA - ECBCS Annex 47 is to enable the cost-effective commissioning of existing and future buildings in order to improve their operating performance. The commissioning techniques developed through this Annex will help transition the industry from the intuitive approach that is currently employed in the operation of buildings to more systematic operation that focuses on achieving significant energy savings. The Annex will also exchange information on commissioning practices in different countries and disseminate relevant information to national practitioners.
Key outputs of IEA - ECBCS Annex 47 include:
