One of the most important relationships in the commissioning process is between the commissioning agent, the owner and the engineer of record (EOR). A relationship that requires ongoing coordination with common goals defined from the beginning of the project. But what happens during Design-Build projects when the relationship between the EOR and contractors may result in different goals and can cause a conflict of interest? This paper provides a resource for all commissioning agents participating in a design-build project and offers guidelines to use to navigate from design to construction and to occupancy as effectively as possible.

This paper addresses issues from DGNB refurbishment and explores how a design process can be streamlined to address refurbishment and still preserve the gains from IED. Registration of the existing conditions is a prerequisite for a good design process where the software tools developed to ensure low energy consumption and good indoor climate can be used, and 3D scanning is therefore making a new and important contribution. The paper includes case studies of both ideal and applied design processes from an architectural office that specializes in sustainable projects.

Automated fault detection and diagnosis (AFDD) methods, followed by corrections, have the potential to greatly improve a building and its system’s performances. Existing AFDD studies mostly focus on component and sub-system AFDD. Much less effort has been spent on detecting and diagnosing faults that have a whole building impact. In this paper, an integrated data driven method: Pattern Matching Principle Component Analysis method, is developed and applied for whole building fault detection. Real building data that contains artificially injected faults and naturally occurred faults are used to evaluate the method’s accuracy and false alarm rate. The method presents great potential to be a cost-effective and accurate whole building fault detection strategy.

This paper explores opportunities for, and impacts of potential regulated energy performance and emission reduction standards for existing buildings in British Columbia. It includes evaluation of four standards – Standard 100-2015, Standard 90.1-2010 (BC Building Code), National Energy Code of Canada for Buildings-2015 and retro-commissioning procedures. Standards are applied to the existing building stock, except low-rise residential buildings, at the time of existing building alterations or repairs that trigger the BC Building Code or Vancouver Building Bylaw.
