Summary: | The life cycle optimization (LCO) of zero carbon buildings (ZC) was examined, using a laneway house built with photovoltaic and solar air wall (SAW) renewable energy collection, air-to-water heat pump, smart grid-integrated thermal storage (SGTS) hydronic battery with an internet-connected stochastic (predictive) control system in subarctic Edmonton, Alberta, Canada. LCO is for global warming potential (GWP), energy, cost, and renewable friendliness. A life cycle assessment (LCA) based methodology (carbon return on investment – CROI) is proposed for design and retrofit decisions on the basis of GWP and cost. Sustainable building rating systems are modelled for their effectiveness in reducing GWP and energy use and are found to reduce life cycle GWP by 18.3% (LEED 2009 certified), 60.7% (PassivHaus 9.30), 96.9% (net zero) and 97.2% (zero carbon) compared to a home built to Alberta Building Code 2014 (base model – BM) over an 80 year life cycle. LCA of the ZC laneway house found a 94.4% reduction in GWP ... |
