Energy Auditing

Facilities Planning and Design

Entech has been providing comprehensive energy audits since our inception in 1981. Our energy audits provide our clients with a thorough understanding of how energy is being expended and utilized at their facility or campus. Entech’s analyses and designs have realized cost savings in the millions of dollars for our clients. The institutions we serve have benefited from Entech’s specialized evaluation of energy rates and exploration of countless energy saving opportunities often otherwise unknown to our clients.

Entech considers a variety of energy reduction techniques for building systems. Energy savings in mechanical systems often involve the incorporation of central heating plants, geothermal heat pumps, cogeneration, fuel conversion, thermal storage, and summer shutdown of boiler systems. Energy savings in electrical projects may include upgrades to electrical systems, peak shaving opportunities, utility monitoring and control systems, and replacement of obsolete indoor and outdoor lighting systems. The modernization of water and wastewater systems is also investigated, adding to the potential for substantial energy reduction, subsequent cost savings, and improved human comfort levels.

The latest methods for modeling mechanical and electrical systems are employed to assess both theoretical and actual energy use. Energy Conservation Opportunities (ECOs) are presented, identifying practical methods for reducing energy consumption and cost. Entech’s ECOs include a description of the energy conservation opportunity, a recommended solution, estimated construction cost, and economic analysis (i.e. simple payback and NPV).

Entech’s Energy Audit process includes a comprehensive data-gathering effort to ascertain baseline conditions including utility rates, operating schedules, demand profiles, and other pertinent information. We complete a thorough walk-through inspection of the area being audited in order to obtain lighting levels, temperatures, loads, flow rates, occupancy, and occupant interviews. Each facility’s theoretical energy use, due to building heat loss and cooling requirements, is calculated and compared to the facility’s energy bills. When the energy bills confirm our energy models, we can provide calculations of realistic savings potential through our energy conservation measures. We then provide a report that is clearly written to fully inform technical and non-technical personnel alike. Report information and the supporting documentation is made available on Entech’s web-based FM-Assistant© database. Comprehensive written reports and plans are also produced to communicate the findings of the comprehensive energy analyses.
