BOILERS
Boiler Systems Engineering is a section of articles in the June 2011 issue of HPAC Heating/Piping/AirConditioning Engineering; a strong emphasis on increasing energy efficiencies runs through the following selection of five articles:
1. "Navigating an Energy Audit," by Steve Connor, Cleaver-Brooks, distinguishes between two kinds of energy audits, the simple system audit and the complete facility audit. How they are conducted, their costs, and how long they can be expected to take are all covered.
2. "Reducing Hospital CO2 Emissions with Condensing Boilers" was written by Ramez Naguib, PE, LEED AP, CEM; Harsco Industrial Patterson-Kelley. Predictions for the reductions are based on modeling.
3. "Optimizing Efficiency with Multiboiler Systems" was authored by Larry J. Ashton, Raypak, HPAC Heating/Piping/AirConditioning Engineering. With several boilers onsite, only some will be needed most of the time. The rest can remain unfired until needed.
4. "Modulating Fan-Powered Economizers," by Steen Hagensen, Enervex Inc., shows how these economizers are superior to traditional economizers. Both types are described and compared; performance tables for each are included.
5. "The Quest for Maximum Boiler-System Efficiency," by Ron Rajecki, Senior Editor, is a discussion of the newer boiler technologies and control systems for water flow.
BUILDINGS
"Libraries in the LEED," by Jacquelyn Marie Erdman, was submitted by Greg Landgraf to the American Libraries Magazine website on July 19, 2011. The author features a LEED-registered branch of the District of Columbia Public Library with insights into how staff and library patrons experience the building.
"Historic Preservation by Creating a Geothermal District," by John Horst, Radcliffe Institute for Advanced Study, et al, was published in the May 2011 issue of Geo-Heat Center Quarterly Bulletin. The institute's historic Fay House was able to be added to a large five-well geothermal system that had been designed for the building next door.
COGENERATION
The following two articles were published in the May-June 2011 issue of Cogeneration & On-Site Power Production:
1. "Birmingham Uses CHP and Trigeneration in District Energy Scheme,” by Simon Woodward, Chief Executive of Cofely District Energy (Crawley, Surrey, UK). The city of Birmingham, in the West Midlands of the UK, is responding to climate change and high energy costs with a plan that has been in the works since 2003. The plan is being implemented in three phases, all of which are well-described.
2. "Why Industrial-Scale Cogeneration Is Right for the US" was written by David C. Oehl, President, Maven Power. The author, from a firm supplying onsite-power engineering services, makes the business case for cogen in this country, largely based on the low prices of natural gas which are expected to continue into the future.
POLICY – INDUSTRIAL TECHNOLOGIES
Crossing the Valley of Death: Policy Options to Advance the Uptake of Energy-Efficient Emerging Technologies in U.S. Industry is a 21-page paper from the Alliance to Save Energy (ASE). It was Web-posted May 4, 2011 on the ASE website; its ASE joint-authors are Jeffery Harris, Sr. Vice President, Programs, Paul Bostrom, Sr. Industrial Associate, and Robert Bruce Lung Sr., Industrial Program Manager. The paper focuses on policy options to ensure and speed up the adoption of these technologies. The options fall under four categories: integrating emerging technologies into efficiency efforts, understanding the connection between energy reductions and air quality, education and outreach for technical information, and cooperative public-private ventures.
