Golden and Superior adopt new energy efficiency guidelines for construction projects

In a recent meeting held by the Colorado Energy Office, key discussions centered around the Golden Sustainability menu and its implications for energy codes in the state. As the sun streamed through the windows of the conference room, board members delved into the specifics of the energy code, highlighting mandatory requirements and innovative options designed to enhance energy efficiency and sustainability in new constructions and renovations.

One of the standout features of the Golden Sustainability menu is the requirement for photovoltaic (PV) systems to offset at least 10% of a building's annual electrical consumption. This is complemented by the mandate for programmable thermostats to exceed existing energy savings benchmarks by an additional 4%. The board noted that while the 2021 International Energy Conservation Code (IECC) set a baseline of 20% savings, the new standards push for even greater efficiency.

The conversation also touched on the inclusion of electric vehicle (EV) charging infrastructure, which is now a part of the sustainability framework. The board established a maximum fenestration U-value of 0.25, a step forward from the previous standard of 0.30, indicating a commitment to improved building performance. Additionally, the use of WaterSense fixtures has been made mandatory, further emphasizing the focus on resource conservation.

During the meeting, questions arose regarding the applicability of certain guidelines, particularly concerning daylighting and passive lighting options. It was clarified that these provisions are not mandatory but are available for both new constructions and renovations, allowing teams to select what best suits their projects.

The board also introduced a points system to incentivize energy efficiency. For every 2% increase in energy efficiency beyond the mandated 4%, builders can earn one point. Similarly, points can be accrued for reducing traditional energy use through renewable sources and for installing additional EV chargers.

As the meeting progressed, discussions shifted to amendments in the town of Superior, where commercial buildings are now required to be all-electric unless they meet specific efficiency standards for combustion equipment. This aligns with the broader goal of transitioning to more sustainable energy practices across Colorado.

The meeting concluded with a sense of urgency and purpose, as board members recognized the critical role these energy codes play in shaping a sustainable future for Colorado. With the implementation of these new standards, the state is poised to lead the way in energy efficiency and environmental responsibility, setting a benchmark for others to follow.
