Abstract

Energy-related decision making for a building is a demanding task, due to the challenges associated with energy system performance prediction. Performance prediction can be done either with simulation tools or by referring to the building energy performance databases. However, in Canada, interactive building energy performance databases that allow the evaluation of different energy efficiency improvement options based on actual data are not found. Therefore, most of the Canadian building construction and retrofitting projects adopt the energy simulations. However, simulation results can contain errors due to multiple reasons including data uncertainty and challenges in capturing system deterioration. Therefore, actual energy performance data is needed to support the simulation results and to inform the designers regarding the actual performance of different energy system configurations under varying environmental conditions over the years. Thus, post-occupancy energy monitoring mechanisms and building energy performance databases need to be developed for continuous data acquisition. Building energy performance is known to have a high correlation with the building indoor environmental quality, which creates high health impacts on occupants. Therefore, human health impacts associated with building energy efficiency measures have to be considered at the design stage. However, lack of information about the actual indoor environmental quality impacts associated with different retrofits and operational strategies poses challenges to building designers. Occupant health and energy use monitoring needs to be mandated for new buildings in Canada, in order to overcome these challenges. Moreover, comprehensive databases containing both energy and health performance of buildings need to be developed to inform the building designers and construction industry as a whole. This study discusses the requirements for developing a health-energy monitoring mechanism for Canada. The key parameters need to be monitored and the challenges are identified.
