Optimization of passive solar design and integration of building integrated photovoltaic/thermal (BIPV/T) system in northern housing

In the Canadian north, cost of space heating is very high due to harsh weather, its remoteness, lack transportation, and dependency on fossil fuel imported from South. Since North has an abundance solar energy, significant energy savings with some added construction in houses could be achieved by applying high-performance building envelopes design strategies. The objective this paper investigate potential both passive active strategies improving efficiency northern housing. Firstly, a reference house representing typical single-family home modeled using EnergyPlus, key parameters are optimized minimize life-cycle cost. Then, air-based integrated photovoltaic/thermal (BIPV/T) system applied HVAC systems. It found that optimal can reduce demand 42% incremental 8% for Yellowknife 27% without incurring Kuujjuaq. Integrating BIPV/T systems defrost time heat recovery ventilator (HRV), extend working hours improve COP air source pump (ASHP). reduction total consumption range 1.4%–3.0% integrating HRV 0.3%–0.6% ASHP mis-match availability demand. To maximize utilization available, use thermal recovered housing requires further investigation.
