Net-Zero Energy Homes: Solar Photovoltaic Electricity Scenario Analysis Based on Current and Future Costs

摘要

The Net-Zero Energy Home (NZEH) Coalition has a vision that all new home constructions are to meet a Net-Zero Energy Home standard by 2030. During this time, the price of energy efficiency measures, renewable energy technologies, electricity and fuels will likely fluctuate, ultimately influencing the affordability of NZEH. To evaluate the potential impact of the price fluctuation on NZEH construction costs, this study compares various combinations of energy efficiency measures and renewable energy technologies integrated into a newly constructed all-electric single-detached Quebec residence such that the annual energy production is equal to the home's annual energy consumption. For each scenario, the study evaluates the cost of constructing a NZEH today based on actual costs to that if the house were to be built in 2030. The effect of a potential photovoltaic technology cost reduction due to increase market penetration is also examined.
