Of course, those people weren't in HVACR Week's opening general session to hear Robin Crow, owner of Dark Horse Recording, deliver his message on the absolute power of service. Crow, who brought along five electric and acoustic guitars (including an amazing acoustic double- neck rig that had the most amazing sound), delivered an incredible talk on how he succeeds in an industry that is in decline. His success is based on che concept of exceeding customers' expectations.
Infrared heaters help efficiently heat spaces for which traditional heating options would not be sufficient. Most of us, for example, have eaten in the outdoor area of a restaurant on a cool evening, the chill being kept away by radiant patio heaters.
We began the year with a new President and a new Congress, both of whom campaigned on promises of reducing energy use and increasing environmental regulations. The economy was still - is still - in the doldrums, and we fiad a refrigerant phaseout deadline looming. And yet, we've been successful as an industry in many ways this year, despite some obstacles. Let's take a look at some of the things we've done:
It's no secret that there has been significant criticism of the certification process for the U.S. Green Building Council's (USGBCs) Leadership in Energy and Environmental Design (LEED) Green Building Rating System. In February, HPAC Engineering Editorial Advisory Board member Mark S.
So how does this benefit the professional engineer? Because of its ability to use Web links, Twitter posts (called "tweets" in Twitter-speak) can be the means to get proposals and design-update announcements to clients faster than a phone call. If you're attending a trade show with several members of your team, you can cover it with more precision than ever before.
Thomas Friedman] is one of my favorite authors and is also a columnist for The New York Times. On April 15, 2007, in an editorial in the Times titled, "The Greening of Geopolitics," Friedman put forth his now-famous proclamation that, "Green is the new red, white and blue." His book, Hoi, Flat and Crowded, continues the theme that American environmental leadership, coupled with American ideas and ingenuity in alternative energy, can help America regain its international stature.
There are two types of high-efficiency gravity-flushing toilets - single- and dual-flush. A high -efficiency, gravity, singleflush toilet uses no more than 1 .28 gallons of water per flush. Dual-flush toilets use 1.6 gpf for a full flush and 0.8-1.1 gpf for a short flush. Several studies conducted by water utilities have concluded the average flush volume for a dual-flush toilet is 20% or less than conventional 1.6 gpf toilets.
This industry has so many ways to keep the heat inside buildings - solar thermal and photovoltaic, condensing boilers, tankless water heaters, radiant, geothermal heat pumps, inverter heat pumps, heat recovery ventilators and more. Manufacturers are trotting out that technology at an increasing rate as the editors and staff of Green Mechanical Contractor saw at the International Builders Show and at the Air-Conditioning, Heating & Refrigerating Exposition this past January.
Once a person is familiar with the language, "We're having a charrette tomorrow at 8:00 AM about that brownfield project. They've decided to go LEED-GoId." becomes "We're having a meeting tomorrow at 8:00 AM about that contaminated land project. They have decided to go for a building certification."
In his blog "Cutting Training in a Down Economy Is not a Smart Move" www. pinpoint performance. netlblogsljustin_bellerlcutting_ training_down_economy_not_smart_move) , Justin Belter, performance-improvement specialist and instructional designer, writes, "If you are thinking of cutting back on your training budget just to save money and ride out our current economic storm, you are actually doing more harm than good to your organization's bottom line.
The term "ventilation" historically has been used to define the amount of outdoor air provided to a space; the term "ventilation effectiveness" is used in Standard 62.1 to describe the portion of outdoor air introduced into the occupied region of a space. However, HVAC systems also must account for outdoor-air ventilation loads, systemic inefficiencies, and distribution losses.
Or maybe green has been here all along, but previously went by a name that wasn't as catchy. In a classic case of what's old is new again, Johnson Controls Inc. (JCI) announced during Greenbuild that it is promoting the concept that efficiency is the first step toward sustainability. Imagine that, energy efficiency is green. Or is it green is energy efficiency? Either way, that's how JCI sees the future of sustainability.
According to a new International Facility Management Association report, "Green Practices 2008," facility managers increasingly are following a master plan when implementing sustainable practices and are tying their efforts to measurable goals and business strategies.
At 2,000 ft and with 150 floors, it would be the second-tallest residential building in the world and stand taller than Chicago's Sears Tower and New York City's upcoming Freedom Tower. While 30 percent of The Chicago Spire's units are pre-sold, the developer has put the project on hold. In addition, construction on the 90-story Waterview Tower and the Shangri-La Hotel, just across the river from the Trump Tower, was halted several months ago.
HPAC Engineering Editorial Advisory Board member William P. Bahnfleth, PhD, PE, a professor of architectural engineering and director of the Indoor Environment Center at The Pennsylvania State University in University Park, Pa., was honored twice during the American Society of Heating, Refrigerating and Air-Conditioning Engineers' (ASHRAE's) 2008 Annual Meeting, held June 21-25 in Salt Lake City.
Some of the complaints are justified. For example, a project seeking LEED for New Construction certification can earn a point for installing a bike rack. Certainly, it's a good thing to encourage people to ride a bike to work. It gets cars off the roads, saves gas, and reduces carbon-dioxide emissions. The problem is if you install an energy-efficient HVAC system, you also get a point.
Mr. [Steve Tom, PE, PhD] is correct in urging caution regarding the oversizing of VAV boxes. However, the cycling on and off of VAV boxes to maintain space-temperature set point is a fact of life, regardless of the accuracy of box selection. I suggest a 20-percent oversizing limit for VAV boxes.
Thankfully, that's what separates the greenbuildings initiative from the consumer-level green movement. The U.S. Green Building Council (USGBC) has specific criteria that must be met for a building to qualify as Leadership in Energy and Environmental Design- (LEED-) certified. Critics complain that LEED has its flaws. For example, certification doesn't ensure that a building is energy-efficient, a key factor for a green building, according to most engineers and building owners and managers.
