Information Exchange Requirements to Support Commissioning of HVAC and Building Envelope Components During an Energy Retrofit Project - A Comparative Case Study

摘要

In order to support a variety of commissioning processes in an automated way, differences and commonalities regarding information exchanges and data flows associated with the commissioning of different types of systems and components should be identified and formalized. In relation to this, we investigated the construction phase of an energy retrofit project in Philadelphia, PA. Specifically, we studied two systems that directly affect the energy consumption, occupant comfort and the operation costs of a facility: the Heating Ventilation and Air Conditioning (HVAC) system and the building envelope. First we identified tasks, stakeholders and required information exchanges. Then, comparing these information exchanges with the Model View Definition of the Industry Foundation Class schema, we analyzed whether these exchanges exist or have to be created to support the use of computational tools during commissioning processes. This paper summarizes our findings.
