7 Building Up a (More Efficient) Head of Steam:
Enwave upgrades district heating plant
Richard Parrish
The construction of a new hotel tower provided an opportunity for Enwave to accelerate its
plan to upgrade the nearby Pearl Street plant, resulting in impressive reductions in emissions
and operating costs.
21 Thermal Energy Storage:
Optimizing district energy systems in more ways than one
John S. Andrepont, President, The Cool Solutions Company
Widely recognized for easing peak electric demand during the summer, thermal energy
storage can also enhance operational flexibility, efficiency and reliability for district energy
system operators.
29 The Campus Geothermal Revolution:
Applying geothermal systems in a new way
Michael Luster, PE, LEED AP, Project Manager/Senior Mechanical Engineer,
MEP Associates LLC
Geothermal heat pump systems are increasingly viewed as an attractive option for
campuses seeking to reduce fossil fuel consumption and lower operating costs.
42 Water: The Linchpin of District Energy
Jonathan Lanciani, Cofounder and President, Organica-Sustainable Water;
Don Safrit, PE, Senior Technical Specialist, McKim & Creed Inc.
The on-site treatment and reuse of wastewater can provide a uniform and reliable supply
of nonpotable water for district energy systems.
ON THE COVER: The U.S. Capitol Building, begun in 1793, is an excellent example of 19th-century neoclassical
architecture. Its design features – derived from ancient Greece and Rome – evoke the ideals that guided the nation’s
founders as they framed their new republic. It is one of many Capitol Hill buildings whose heating and cooling
needs are provided by the Capitol Power Plant.
