Using Performance Simulation in the Commissioning and Monitoring of a Net Zero Energy Home
Abstract
Abondance Montréal is a net-zero energy “triplex”, a typical 3-unit apartment building in Montreal. This paper reports the lessons learned during the commissioning phase of the building and in setting up the monitoring system. As-built numerical simulation is used to assess performance against design specifications, without having to wait for measured yearly performance results. Commissioning results are used to validate and fine-tune the simulation inputs. This allows detecting and remedying operating problems that are not critical but lead to a degradation of the energy performance. After the commissioning phase, a detailed monitoring system is implemented to allow a full performance assessment and to provide data for calibration of the design simulations. Comparison between design simulation and recorded performance is compared to simulation outputs.
