Thomas Watson, ASHRAE’s 2012-2013 president and retired chief engineer for Daikin Applied, recently received The Institute of Refrigeration’s J&E Hall Gold Medal Award for his work to improve the efficiency of chillers and industrial heat pumps....More
With commercial structures certified under the LEED rating system, owners/operators tend to assume they simply can “set it and forget it.” Such an approach is inherently flawed, as the performance of all buildings “drifts,” or degrades, over time....More
The USGBC released “LEED in Motion: Venues,” which highlights efforts to transform the environmental, social, and economic footprint of convention centers, sports venues, performing-arts centers, community centers, and public-assembly spaces....More
The 2017 International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo) broke three show records: overall attendance, exhibit space, and visitors. Here is your guide to some of what you may have missed.
Free cooling has been around for years, with systems limited to low chilled-liquid temperatures and operation during winter. Recent trends in buildings and increased focus on energy conservation, however, have sparked an evolution in chiller design....More
Effective March 16, earners of ASHRAE’s Building Energy Assessment Professional (BEAP) certification will receive recognition by U.S. government agencies for contracts requiring energy-audit services....More
Recently, I needed to ask my friend Rob Tanner, a Florida attorney who is board-certified in construction law, for legal advice. Even if you’re not in Florida, you may find some of what Rob has to say helpful, so I interviewed him for this post....More
The USGBC recently announced the top 10 states for the LEED green-building rating system, an annual ranking highlighting states that made significant strides in sustainable-building design, construction, and transformation over the previous year.
During its 2017 Winter Conference Jan. 28 in Las Vegas, ASHRAE recognized outstanding achievements in building design in the areas of occupant comfort, indoor-air quality, and energy conservation as part of its 35th Technology Awards program.
Despite a 14-percent increase in total buildings and a 22-percent increase in total floor space, U.S. commercial-building energy use increased just 7 percent from 2003 to 2012. Still, there is much room for improvement....More
It is inevitable: Over time, your facility’s HVAC will break down or require an upgrade. When that time comes, you must decide whether to refurbish, retrofit, or replace equipment. In the case of fan-coil systems, each option has pros and cons....More
Factors limiting the use of computational fluid dynamics have been lengthy modeling and setup time, expensive software licenses, and extensive training requirements. These challenges are being overcome with a new generation of cloud-based software....More
Data breaches and other cyber crime cost companies billions each year worldwide, and the damage to brand reputation can be incalculable. Since hackers look for weakly defended systems to attack, this paper presents 5 cybersecurity “best practices” to mitigate system vulnerabilities. Some are commonsense measures like effective password management; others involve securing open ports and other access points, software upgrades, user management, and vulnerability plans....More
A top priority for higher education institutions is to provide a competitive learning environment for their students. In order to succeed, they must address outdated, aging campus facilities. In these older buildings maintenance and operations costs are high, space utilization is inefficient and poorly managed, and current technology is lacking. This white paper explores four strategies for converting campus facilities into a network of smart buildings that address the needs of current and future students....More
