BUILDING ENVELOPE OPTIMAZATION METHOD AND APPLICATION TO THREE HOUSE TYPES IN A PROPOSED SOLAR DISTRICT ENERGY SYSTEM
Chris Kirney, Anil Parekh, Keith Paget
A simple cost optimization method was applied to determine the appropriate investment in energy efficiency for houses to be built as part of a large scale solar community planned for construction near Calgary, Alberta. The cost effectiveness of individual house envelope energy efficiency upgrades was determined using energy simulation results and builder contributed costing information. These results then guided the combination of house energy efficiency upgrades. Finally, the incremental costs of these combined upgrades were compared to the estimated incremental cost of providing space heating using the planned solar district heating system to determine the appropriate house energy efficiency upgrades.
