Annex 47 Objectives
 Extend methods and tools to advanced systems in low energy buildings
 Automate commissioning process to the extent practicable
 Develop methodologies and tools to improve operation of buildings in use
 Quantify and improve costs and benefits of commissioning, including the
persistence of benefits and the role of automated tools in reducing costs
and improving persistence
 Exchange information on commissioning practices in different countries
and disseminate relevant information to practitioners
