미국 내무부(DOI)가 최근 에너지 효율 및 재생가능에너지 기업인 Ameresco사에 에너지절약운영계약(ESPC)을 수주했다고 발표했다. 20년 기간의 이번 계약은 총 7천700만 달러의 가치를 가지며, 워싱턴DC에 있는 DOI 본사 건물에 물 보존 및 에너지 효율화 방법과 현재의 에너지 관리 서비스를 제공·실행하도록 고안됐다.

Ameresco는 종합적인 ESPC를 통해 DOI의 7층 규모 건물 내에서 에너지 및 물 소비를 줄이기 위한 여러 방법을 실행할 예정이다.

 

 

 

The U.S. Department of the Interior (DOI) recently announced that it has awarded an Energy Savings Performance Contract (ESPC) to Ameresco, Inc., (NYSE:AMRC), an energy-efficiency and renewable energy company. The contract, valued at $77 million over a 20-year term, is designed to provide for the implementation of water conservation and energy-efficiency measures and ongoing energy management services to the DOI headquarters building in Washington, D.C.

 

Through the comprehensive ESPC, Ameresco will install a combination of measures to reduce energy and water consumption within the seven-story, 1.3-million-square-foot facility. The project is designed to reduce domestic water consumption by 70 percent by installing new plumbing fixtures and harvesting groundwater that is currently collected under the building and discharged to storm drains. Ameresco will treat and store the groundwater in a re-purposed chilled water storage tank for non-potable uses including irrigation, cooling tower makeup water supply, and toilet and urinal flushing in bathrooms.

 

The energy-efficiency project is also expected to reduce electricity consumption by 31 percent and to reduce steam utilization by 12 percent. These reductions will be accomplished by installing over 9,400 solid state/light-emitting diode (LED) technology fixtures. They will be controlled by a new advanced lighting control system that will be integrated into the building automation system to control space lighting in offices based upon occupancy.

 

The ESPC is expected to result in first-year savings of more than $3.2 million and to provide for $87 million in energy and cost savings during the 18-year performance period and two-year implementation period of the contract. Overall, the ESPC will reduce DOI's greenhouse gas emissions by 24 percent and will support it in meeting Federal sustainability requirements, including several of those outlined in the March 19, 2015, executive order, "Planning for Federal Sustainability in the Next Decade."
