Our Services
These measures and upgrades often include lighting, water, heating, ventilation, cooling, building envelope, smart meters and controls. We first implement efficiency gains in order to establish a strong baseline for renewable energy generation needs.
Examples of distributed energy generation resources include Solar PV, CHP and co-gen plants, geothermal, renewable natural gas, wind – all of which can be paired with microgrid and battery storage technologies to promote resiliency and sustainability.
We have experience in building modernization and retrofits, and work with utility distribution systems and non-energy-focused design-build new construction. We also monetize existing energy assets and take ownership and operation off the customers’ balance sheet.
Data drives our energy analytics and supply management solutions ranging from our proprietary asset management software, AssetPlanner®, to energy procurement services for negotiating contracts and stabilizing customers’ energy budgets.
Our holistic approach ensures end-to-end technical guidance to continued O&M of energy systems. A well-designed and properly executed O&M program is a crucial element in the equipment performance and maintenance required to realize all possible energy savings.
Ameresco is uniquely positioned to provide financing for any opportunity – from ESPCs and PPAs to Design-Build and turnkey EaaS. We have 20 years of experience with an excellent track record of $6+ Billion in energy projects across financing models, markets, and technologies, utilizing available incentives.
Ameresco helps organizations meet energy saving and energy management challenges with an integrated comprehensive approach to energy efficiency and renewable energy. Leveraging budget neutral solutions, including energy savings performance contracts (ESPCs) and power purchase agreements (PPAs), we eliminate the financial barriers that traditionally hamper energy efficiency and renewable energy projects.
Drawing from decades of experience, Ameresco develops tailored energy management projects for its customers in the commercial, industrial, local, state and federal government, K-12 education, higher education, healthcare and public housing sectors.
