Integrated Energy Systems promote the integration of total building energy management into the selection of technologies used to heat cool and power the a single building or a campus of buildings. Electricity to such buildings is provided by on-site or near-site power generators using one or more of the many options: internal combustion (IC) engines, combustion turbines, microturbines, and fuel cells. In CHP systems, waste heat from power generation equipment is recovered for operating equipment for cooling, heating, or controlling humidity in buildings, by using absorption chillers, desiccant dehumidifiers, or heat recovery equipment for producing steam or hot water. Integrated Energy Systems (IES) research and development projects targeting the commercial building sector have the potential to:
IES research and development projects targeting the commercial building sector have the potential to:
- Dramatically reduce fossil fuel use and air pollutant emissions
- Improve the electric grid's power quality, efficiency, reliability and return on investment
- Enhance energy security
DOE has installed a building integration "test site" at an office building on the campus of the University of Maryland at College Park. Some of the objectives of the test site are to study how the CHP system integrates with the building systems (HVAC and electrical) and how the system integrates within itself. Ronald Fiskum, a Program Manager for DOE's Office of Distributed Energy, says, "In the near future, CHP for building systems will be engineered in the factory - instead of in the field. The system behind the building here at the
University of Maryland may one day be on just one skid. You bring the whole skid in, you hook up the electrical, and you're ready to go."
There are seven industry teams that have IES cost-shared projects.

Gas Technology Institute
(PDF 1.5 MB)
The Gas Technology Institute, Waukesha, Trane, Ballard Engineering Inc., Charles Equipment Co., and the University of Illinois at Chicago have teamed to develop and demonstrate reciprocating engine generators ranging from 290 kW to 770 kW matched with absorption chillers (e.g., 90 RT) to optimize performance. Modularized, "plug and play" integrated energy systems are easily adaptable to various requirements for electricity, hot water, and chilled water. The team is using market analysis to guide the development of this system and expedite commercialization.

Burns & McDonnell
(PDF 984 KB)
Burns and McDonnell teamed with Broad USA, Solar Turbines, and Austin Energy to develop a modular system that integrates a 5-MW combustion turbine generator with an advanced waste heat-fired 2,500-ton indirect-fired absorption chiller. The system will be owned and operated by Austin Energy and will provide electricity to a microgrid and chilled water to a high-tech industrial park.
In addition to improved reliability through onsite generation and producing 2,500 tons of free cooling, the system will displace 2,500 tons of electrical centrifugal chilled water during peak periods. The system's modular design is adaptable to various capacity, space, and grid interconnection requirements.

Honeywell Labs
(PDF 1.9 MB)
Honeywell Labs has teamed with Broad USA, Chelsea Group, and I.C. Thomasson to develop reference designs to improve economics and simplify installation. Honeywell Energy Services is installing a prototype system at the Fort Bragg Army Base. The prototype features a 5-MW turbine generator integrated with a 1,000-ton Broad USA absorption chiller fired with waste heat or gas to meet air conditioning needs. Turbine exhaust can also be used to produce steam. A supervisory control system will optimize energy supply.

NiSource Energy Technologies
(PDF 1.3 MB)
NiSource Energy Technologies and Rahmat Shoureshi, controls consultant, are developing, integrating, and packaging an energy system that optimizes facility energy use by combining multiple 60-kW microturbines in packaged systems. The project builds on a successful hotel installation in Chesterton, Indiana, to develop future applications in other industries with high water-heating needs. The system optimizes energy options for a facility's specific energy use patterns including space heating, thermal load from hot water heating, and swimming pool and spa heating.

United Technologies, along with Capstone Turbine Corp., is accelerating the development of packaged integrated energy systems by fast-tracking preparations for a test facility. The team is analyzing factors that influence market success by developing a screening tool and optimizing the modular system to achieve significant savings. The team is defining modular systems using multiple 60-kW microturbines integrated with a Carrier absorption chiller. The small size of this system means it is especially well suited to retrofit applications and can augment existing systems.
