New energy efficient lighting has been installed at the Civic Center, as well as field lights and external building lighting at Garden Acres Park. These upgrades were identified during energy efficiency assessments of the properties and have received rebates from Efficiency Works. Estimated annual energy savings from these lighting improvements is 30,586kWh. To continue efforts to identify City facility efficiency opportunities, Efficiency Works energy assessments have been conducted at both the Quail Recreation Center and the Library.
Construction is completed on both a 200kW city-owned solar installation at the Waste Services Building on Martin St and a 211kW city-owned solar installation on the Longmont Housing Authority (LHA)/partner owned Ascent at Hover Crossing low-income multi-family development. The Martin St. system was energized in September 2025 and has provided energy offsets to participants since October 2025. The Ascent at Hover Crossing system was energized in January 2026 and bill credits have been issued to each occupied unit since. These projects were funded through capital improvement project funds and staff anticipates receiving at least 30% of the installation costs back via elective pay through the Inflation Reduction Act (IRA). Work is underway to identify additional City-owned sites for solar installations to support program expansion.
Construction has concluded on a project to install a 10 kW solar photovoltaic (PV) installation on the roof of the recently constructed maintenance building and adding battery storage to further reduce energy demand from the City's wastewater treatment plant (WWTP). Environmental Affairs was awarded a Renewable and Clean Energy Challenge grant through DOLA to support a project at the City's (WWTP) to install the solar and battery storage and to purchase two new high efficiency blowers to reduce energy consumption of the secondary process by 25% (over 600,000 kWh annually).
New energy efficient lighting has been installed at the Service Center, in limited areas of the Utility Center, as well as at the Sunset Campus. These upgrades were identified during energy efficiency assessments of the buildings and have received rebates from Efficiency Works. Estimated annual energy savings from these lighting improvements is 33,000kWh.
