La revisión periódica del uso energético en las instalaciones de la ciudad de Longmont ayudará a identificar más opciones para mejorar la eficiencia energética, la gestión del pico de consumo y las tecnologías de energías renovables, para así ayudar a la ciudad a reducir el consumo energético y los gastos asociados a las instalaciones municipales.
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 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.
Construction is completed on a 200kW city-owned solar installation at the Waste Services Building on Martin St and is almost complete for a 211kW city-owned solar installation on the Longmont Housing Authority (LHA)/partner owned Ascent at Hover Crossing low-income multi-family development. Projects were funded through capital improvement project funds and staff anticipates at least 30% return via elective pay through the Inflation Reduction Act (IRA). The Martin St. system was energized in September 2025 and is providing energy offsets to selected participants. The Ascent at Hover Crossing system is expected online with credits being issued to each of the 75 apartments by end of Q1 2026.
