Effective building envelope and air handling designs took comfort most of the way from theory to reality in ISU’s Hach Hall. An existing in-house deionized water supply and a new fogging system finished the task and saved an estimated 22% in humidification costs.
How can you really, really seal any gap between your pipe and the rest of the wall that just had a hole put in it to accommodate the pipe’s path? That’s a question we haven’t asked in these pages before. Learn about the available technology, bolt/nut combinations, and more to maintain a safe long-term relationship between these elements of your building systems and your building.
This large complex is welcoming a host of new arrivals, from new boilers and chillers to an
overhaul of its hydronic strategy. Avoiding a whole lot of drilling was one benefit of their new design choice. Balancing first cost, maintenance costs, and the system itself were additional positives for keeping all 225 units comfortable and affordable.
Back in January 2011, I wrote in this column about hospital-acquired infection based on my introduction to this serious problem and my participating as a steering committee member for the Hospital Associated Infection Organization (HAIO).
With our next Today’s Boiler scheduled for May, I don’t want to wait that long to keep you apprised on the latest in the ongoing saga of finalizing and implementing new boiler regulations. Even last month’s ABMA meeting is not the latest, but ABMA president Randy Rawson has sent his members (including ES) a good summary of the present situation. So with thanks to him, I am providing an excerpt of his update below. If you have trouble keeping up, don’t feel bad.
There have been dramatic changes to the building controls market over the last 20 to 30 years. The “energy crisis” of the 1970s (along with the development of the microprocessor) sent the “Big 5” dominated pneumatics market into an energy management system (EMS) orbit that was joined by several dozen other manufacturers by the mid-1980s.
In this column, I will describe the “issue” disclosed through analysis of the trend graph included in my January 2012 column. I will also introduce a new system and show its trend graph, leaving it up to the reader to discover the operational “issue” illustrated in the graph. The answer will be given at the start of next month’s column.
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has published an industry-first standard for VFDs. As with all AHRI Standards, 1210 (I-P)-2011 and 1211 (SI)-2011, Performance Rating of Variable Frequency Drives, are available free of charge on AHRI's website.
Thirty-six people were recognized by ASHRAE for their contributions to the Society and the building industry at the Society’s 2012 Winter Conference. The Hall of Fame honors deceased members of the Society who have made milestone contributions to the growth of HVACR technology.
Kloben, Italy’s largest manufacturer of solar thermal equipment, and Universal, one of Italy’s largest solar integration companies, have formed KU Solar to distribute their solar HVAC systems in the U.S.
EE Global will be held March 27-29, 2012, at The Peabody Resort in Orlando, FL.Co-hosted by the Alliance to Save Energy and its affiliated Southeast Energy Efficiency Alliance, EE Global 2012 is the latest annual gathering of influential energy efficiency professionals from around the world.
Energy efficiency and historic preservation are rarely synonymous. More often than not, one must be compromised for the sake of the other. Fortunately, the University of Arkansas found a way around such compromises when it came to the restoration and mechanical renovation of the school’s beloved Peabody Hall.
The USGBC has released its 2011 list of top 10 states for LEED®-certified commercial and institutional green buildings per capita, based on the U.S. 2010 Census information. The District of Columbia leads the nation, with more than 31 sq ft of LEED-certified space per person in 2011, with Colorado being the leading state, with 2.74 sq ft per person in 2011.
As former commercial fishermen who decided to develop their own line of organic oils, the Barlean family was no stranger to innovation. A manufacturer of nutritional lipids products based in Ferndale, WA, family-owned Barlean’s Organic Oils LLC grew so rapidly that it soon needed its own fish-oil production facility.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
