After the collapse of the World Trade Center towers Sept. 11, people in the vicinity faced a new threat: the sudden release of tons of dust and debris into the air. Early reports warned of asbestos risks, then stated that the levels in the air were much lower than anticipated. Many people didn’t believe it.
The American Society of Heating, Refrigerating and Air-Conditioning Engineers’ (ASHRAE) ventilation standard provides new design guidance for controlling odor in indoor spaces where smoking occurs. The addendum does not address health effects relating to smoking spaces — just odors.
Toronto, ON, Canada is expected to have more housing starts this year than any other metro area in North America. This is one of the reasons why Messe Frankfurt Inc. is hosting ISH North America in Toronto on Oct. 31-Nov. 2, 2002.
Humidity and its control have been receiving greater and greater attention, especially their relationship to good or poor indoor air quality (IAQ). So it’s no wonder that an American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) seminar explored “Practical Aspects of Humidity Measurement.”
The U.S. Census Bureau has started to release portions of the data collected from its 2000 Census. Its “Profile of Selected Housing Characteristics: 2000” is now available, and a comparison with the previous 1990 Census data shows where the market has evolved and where it hasn’t.
As the nation continues to grapple with increasing mold problems indoors, it is clear that ventilation and moisture play key roles in feeding mold and then spreading it. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has been questioning whether its own standards, specifically 90.1 on energy-efficient buildings and 62 on indoor air quality (IAQ), have contributed in a significant way.
It’s the middle of summer, the temperature is soaring, and it’s time to think about keeping cool — especially where customers are concerned. So what do you do when you have to take a building’s A/C system offline in order to make repairs? Or worse yet, what do you do when a system breaks down, and you’re going to have to wait a few days for a part? One answer is portable, or temporary, cooling.
When a major department store in a New York mall had a problem with its 600-ton absorption chiller, management needed a quick solution to keep the store cool. NuTemp came through with a portable chilled-water plant and generator.
As part of Carrier’s 100th anniversary celebration, the company has recognized two energy-efficient HVAC investments. Two Chicago buildings were presented with a Carrier Environmental Award at the Building Owners & Managers Association (BOMA) International 95th Annual Convention & The Office Building Show.
Today’s centrifugal chillers offer some of the highest efficiencies ever. The technology may be more advanced, and the refrigerants are newer, but some things remain the same: the systems’ need for regular maintenance.
