Lockheed Martin partnered with SitelogIQ on a DOE II ESPC task order at the DOS Embassy in Managua, Nicaragua. The goal was to improve energy usage and production at the facility. The primary driver of the project was 1.2 MW solar photovoltaic plant. The balance of the project included HVASC RCX and a new chiller. Lockheed Martin asked SitelogIQ to develop bundled energy system improvements to provide the site with cost-effective systems and energy savings under an ESPC. SitelogIQ was responsible for the IGA and Final Proposal. A key ECM was the installation of approximately 1.2 MW of solar PV. This includes both carports and ground mount solar. Further renewable generation including additional PV and wind generation was identified for future phases. Phase one included ECMs, retro-commissioning the existing EMCs, and HVAC. Additionally, this project included the installation of a night chiller to optimize cooling overnight by substituting for the larger chillers. Other measures included the site-wide installation of LED lighting fixtures on both the interior and exterior. Power quality was improved through the installation of transformer upgrades.
Overall this project reduced the energy load of the embassy by 37% and reduced the reliance on the local energy provider.
