The Canadian government, as well as a number of its provincial legislators are gearing up to introduce energy efficiency requirements in building codes that will clearly show how they will step up requirements from current standards up to near-net-zero energy levels over a set number of years. The first Canadian jurisdiction to implement this was in British Columbia (BC), where the government set out the BC Energy Step Code in 2017 that will take the building industry from current performance levels up to Passive House levels by 2032.
In preparation for the release of the BC Energy Step Code, the government funded a large parametric study to estimate the impact of the various steps on costs on housing design. This study evaluated the impact on a number of different archetypes over its vast province that has six distinct climate zones going from 2800 HDD in the Vancouver area, up to 7500 HDD in the northern parts of the province.
Given the quantity of possible energy conservation measures (ECMs) as well as the significant number of climate zones, the use of an optimization software tool to analyze the impacts of the Energy Step Code was determined to be important. The project team made use of the Housing Technology Assessment Platform (HTAP), developed by Natural Resources Canada (NRCan) in 2010, that does optimization using HOT2000, the predominant housing energy modelling software used in Canada.
The use of optimization generates vast amounts of data, with over two million individual energy evaluations done for the BC study. The data was able to inform a range of design possibilities and costs for achieving the Energy Step Code for different archetypes. This presentation explores different data visualization techniques that help in presenting the information in a meaningful way to different stakeholders.
