The presentation will discuss Alberta case studies that have navigated the NECB code requirements and lessons learnt from the experience, ranging from prescriptive compliance to energy modeling. Examples of how the trade-off path can be applied will also be presented. When a project pursues the performance path (energy modelling), there is synergy with other sustainability certifications such as LEED or BuiltGreen.
Early design decisions informed through energy modelling and parametric analysis may help design teams achieve NECB compliance or other sustainability targets in a cost effective manner, and allow more freedom in meeting other project requirements aside from energy. We will also review the challenges of new stringent energy standards on building envelope systems and consequential effects such as energy efficiency, air quality and condensation.
