 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
