Caernarvon 1 is a 3-storey multi-unit residential building located in Edmonton, AB and was constructed circa 1976. The building consists mostly of two-bedroom units. 3D Energy performed an energy analysis and assessment which determined that Caernarvon 1 has an Energy Utilization Index (EUI) of .92 GJ/m², which is 60% more than the median Energy Star EUI for this type of building. After completing a site visit, 3D Energy was able to identify 7 different energy conservation and renewable energy measures.

Of the 7 measures analyzed, 3D Energy recommended implementation of 6 measures that would save approximately $15,803 a year with a simple payback of 2.8 years. These measures included lighting upgrades, programmable thermostats, and recommissioning the heating system. The remaining conservation measure was not recommended due to a long payback period. If implemented, the recommended ECMs would result in a massive 66% reduction in electricity consumption and 28% reduction in natural gas consumption. Additionally, this would result in an annual reduction of 131.9 tons of CO2e, the equivalent to taking approximately 28 cars off the road.
