"Chilled water thermal storage can provide many energy cost benefits when implemented in chilled water systems. Placing an atmospheric chilled water thermal energy storage tank in a chilled water system will have several engineering ramifications on the hydraulic performance of the system. Understanding these hydraulic implications and designing the optimum solutions for addressing these implications will improve both control and energy performance."

"Every so often, a technology that had been abandoned for a long period of time comes back to life thanks to new developments that make it viable and competitive once again. While it's too early to predict with certainty, this may be the pattern that we see for one of the heating industry's oldest technologies: vacuum steam heating. This article describes the evolution of that technology, its benefits and drawbacks, and a new approach that may make it a cost-effective option in the 21st century.

"Seattle Steam Co. has long carried the district energy torch in Seattle, from its founding in 1893 to its position today as a leader in the city of Seattle's carbon reduction efforts. The company's switch to renewable biomass fuel in 2010 helped pique the city's interest in district energy expansion....."

Planning for District Energy, CHP and Microgrids: A Checklist for Campus Administrators

District Energy, First Quarter 2014.
http://www.districtenergy-digital.org/districtenergy/2014Q1?pg=38#pg38

"Owners and operators of multibuilding campuses face significant pressure to reduce operating and capital costs, maintain reliable services and become better stewards of the environment. To meet these challenges, an increasing number of campuses are turning to district energy, combined heat and power and/or microgrids. Effective planning ... will enhance the likelihood that savings associated with the power usage and climate control needs of individual buildings will be realized and that the central plant and distribution system can be ideally located."
