Stirling engine based cogeneration system retrofit impact on the energy requirement and greenhouse gas emissions of the canadian housing stock
Energy end-use and greenhouse gas (GHG) emission impact of retrofitting Stirling engine based cogeneration systems in existing Canadian houses is studied using the Canadian Hybrid Residential End-Use Energy and GHG Emissions Model (CHREM). CHREM includes close to 17,000 unique house files that are statistically representative of the Canadian housing stock (CHS). The cogeneration system performance was evaluated using a high resolution integrated building performance simulation software. It is assumed that the Stirling engine cogeneration system is retrofitted into all houses that currently use a central space heating system and have a suitable basement or crawl space. A high efficiency auxiliary boiler is included to supply heat when cogeneration unit capacity is not sufficient to meet the heating load. The GHG emission intensity factor associated with marginal electricity generation in each province is used to estimate the annual GHG emissions reduction due to the cogeneration system retrofit. The results show that cogeneration retrofit would yield substantial energy savings and GHG emission reductions in the CHS.
