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

Subtasks

Subtask C, Commissioning Cost-Benefits and

Persistence

Subtask B, Commissioning and Optimization of Existing Buildings

Subtask A, Initial Commissioning of Advanced and Low Energy Building Systems

Lifelong Monitoring of low-energy buildings

Objective:

- Develop Software tool and Toolkit

- Follow-up performances “building envelop”, “HVAC”

- Input data from existing components measurement techniques

- Link to EPB and EAP software

We are still looking for SMC’s to join as partners
