Until the advent of modern building codes, most buildings were designed to “breathe,” with air exchange between the interior and exterior. As codes have prioritized energy efficiency, air leakage requirements have led to tighter buildings. While this reduces energy use associated with air infiltration, it also means that buildings require a dedicated source of fresh air to ensure adequate indoor air quality. Learn More

Space Heating and Cooling

Historically, most buildings in Colorado have been heated by natural gas due to the cold winters, available technology, and relatively low cost of natural gas. Today, there are heat pump products that can reliably provide electric heating and cooling in all Colorado climate zones.Learn More

Water Heating

Water heating can be a challenging end use to efficiently electrify. Electric resistance water heaters are dependable and relatively inexpensive to install but have high operating costs. Heat pump water heaters (HPWH) are a more recent market entry with nearly triple the efficiency of electric resistance models. Learn More


Appliances are an important part of the lived experience of an apartment. Electrifying all appliances, especially cooking ranges, has significant health benefits.Learn More

Utility Metering

The electrical metering approach for affordable housing rental properties impacts utility costs, physical space requirements, administrative burden, and rental income. Learn More


Solar photovoltaics (PVs) reduces electricity costs and site greenhouse gas emissions, offering an opportunity to align with Colorado's 2040 100% Renewable Goals. Learn More
