Commissioning on HVAC Systems for Improved Energy Performance: IEA Annex 40 Update



Natascha S. Milesi-Ferretti


The Energy Conservation in Building and Community Systems program of the International Energy Agency has set up Annex 40, a research working group on Commissioning of Building HVAC Systems for Improved Energy Performance. The objective of Annex 40 is to develop, validate and document tools for commissioning buildings and building services. This work includes 5 tasks: 1) the commissioning process, 2) manual commissioning tools, 3) building energy management system assisted commissioning tools, 4) use of models for commissioning, and 5) commissioning projects.The Annex research project has completed its working phase and is currently at the middle of the final-year reporting phase. At this point in the project, the commissioning process is well defined and numerous tools have been developed to facilitate various aspects of commissioning. These tools include standard models of commissioning plans (SMCxPs) for various building types, task lists that can be applied using a cost benefit analysis, and software designed to aid in automation and documentation of tests. Many of these tools have been tested in real building commissioning projects and the lessons learned regarding challenges in development and implementation are being documented.
