IEA-ECBCS annex 47 Cost-effective Commissioning of low-energy buildings Brussels, 28/01/08 Alexis Versele

Outline • Annex 47 • Objectives • Subtasks • Organisations & Management • Status • Belgian contribution 2

Annex 47 Objectives q Extend methods and tools to advanced systems in low energy buildings q Automate commissioning process to the extent practicable q Develop methodologies and tools to improve operation of buildings in use q 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 q Exchange information on commissioning practices in different countries and disseminate relevant information to practitioners 3

Subtasks Subtask A, Initial Commissioning of Advanced and Low Energy Building Systems • Information Flowchart • Information model • General Cx-methodology for advanced & low energy buildings – Functional Test Procedures – Control strategies for advanced systems – Case studies Subtask B, Commissioning and Optimization of Existing Buildings • Tools – Data visualization Subtask C, Commissioning Cost-Benefits and – Field optimization Persistence – Commissioning • Cost-Benefit Methodology • Fully documented case studies • Methodology & tools to enhance persistence • International Database – Commissioning Cost-Benefit – Persistence 4
