Energy inefficient buildings located in cold climates require up to five times more energy to heat than more energy efficient buildings. More stringent construction codes will reduce building energy consumption and thereby lead to reduced energy costs and emissions. For this study, professional energy audits were conducted on two representative buildings and AkWarm Energy Modeling software models of the buildings were generated. The actual energy consumption of the buildings is compared to the modeled energy consumption. The representative buildings are then modeled as if they were constructed to 1975 and 2001 codes, and the energy consumption for the buildings under those construction codes is estimated. The study is novel because it uses actual energy consumption of the buildings to ground truth the models, and then considers how much energy those buildings would consume if their building envelopes were constructed to the standards of other eras. The two modeled buildings are similar to many other buildings located in cold climate regions such as Interior Alaska. Improving the energy efficiency of the existing building stock will reduce the energy consumption, energy costs, and the carbon footprint of the buildings. The findings show the predicted versus actual energy consumption for the two buildings as they are built. The findings also show that a more stringent construction code significantly reduces the energy consumption of the two buildings.
