Energy-Efficient HVAC Revenue to Nearly Double By 2020, Says Report
BOULDER, Colo.—Annual revenue generated by global sales of energy-efficient HVAC systems is expected to surpass $33 billion by the end of the decade, according to a recent study from Navigant Research. The "Energy Efficient HVAC Systems" report concludes that annual revenue from energy efficient HVAC systems is set to nearly double from $17.2 billion in 2013 to $33.2 billion by 2020. "In the wake of the global recession of 2009, developed markets for efficient HVAC... remain sluggish," said Navigant senior research director Bob Gohn. "However, the North American market will revive during 2013 and begin to experience more substantial growth during 2014. Europe will follow a similar trend, but recovery will likely not occur until mid to late 2014."

Researchers Developing Device to Regulate Ventilation Levels
RICHLAND, Wash.—A single advanced building control now in development could reduce the overall annual energy bill of the average large office building by 18%, with no loss of comfort, according to a report by the Department of Energy's Pacific Northwest National Laboratory. The report is based on extensive simulations of the impact of one type of advanced building control now in the offing in the building industry. The device is capable of customizing the level of ventilation by sensing the number of people in different areas or zones of a building and then adjusting fan speed and air movement accordingly. "An 18% boost in building energy efficiency by modifying a single factor is very, very good," said team leader Michael Brambley, Ph.D., Member ASHRAE. "The savings were much greater than we expected."

Tricky Ways to Pull Down a Skyscraper
TOKYO—Tokyo is a city with a lot of outdated buildings located close together. Because razing one building by conventional means is difficult without disturbing another, Japanese companies are perfecting what might be called "stealth demolition." Japanese construction engineers have developed some interesting techniques for urban building deconstruction and recycling, prompted not only by safety concerns but also by changing energy costs, office infrastructure needs and environmental laws. To date, about a dozen buildings have been torn down using two techniques: top-down and bottom-up deconstruction. For example, since last fall the 40-story Akasaka Prince Hotel has had its innards torn apart floor by floor by hydraulic shears and other heavy equipment. The building has been shrinking by about two floors every 10 days. Other cities, such as New York, are studying the Japanese techniques to renew congested business districts.

Businesses Worldwide Increasingly Interested in Energy Efficiency
WASHINGTON—Global interest in energy efficiency has risen 116% since 2010, recent research by Johnson Controls has found. "The Energy Efficiency Indicator," a survey of more than 3,000 decision-makers in 10 countries, analyzed energy efficiency choices, practices and investments. Around 73% of respondents said they have already set energy reduction goals within the last year, up from 58% two years ago. Among the organizations that set public goals, 72% plan to increase their investments in energy efficiency.

Facebook Turns On Data Center at Arctic Circle
STOCKHOLM—Facebook has opened a new data center in Luleå, Sweden, a place that offers plenty of water and a cool climate, as the social network seeks to lower its costs and improve its environmental friendliness. The new data center is Facebook’s first outside the U.S., located about 600 miles (966 km) north of Stockholm at the edge of the Arctic Circle. It is also the first to rely exclusively upon servers designed by the company itself. Facebook says the city's "chilly Nordic air" can be used to cool the thousands of servers in the 290,000 ft2 (27 000 m2) facility. Any excess heat that the servers produce can be used to warm the office. Also, the facility is powered by locally generated, 100% hydroelectric energy, which is so reliable Facebook has been able to reduce the number of backup generators by more than 70%. Sweden’s dense fiber optic network is another reason Facebook chose the Nordic nation to build its first foreign data center.

Insufficient Building Practices Contributing to Storm Damage
MOORE, Okla.—The cost of damage from tornadoes is increasing rapidly in the United States even though National Weather Service historical data shows no significant rise in the number of storms. Damage costs are rising because of increased population density, even in mostly rural states such as Oklahoma, which has seen substantial urban sprawl in the last decade, said Greg Carbin, warning coordination meteorologist for the National Weather Service's Storm Prediction Center in Norman, Okla. Another important reason is that most homes in the "tornado alley" of the central U.S. are not built to withstand even a modest tornado. "This notion that we cannot engineer buildings economically to withstand tornado loads is a fallacy," said David Prevatt, a civil engineer who surveyed damage in Moore, Okla., which was hit by a tornado with the highest strength rating last month. The result is that residents of tornado alley, insurance companies and the U.S. government are footing a mounting bill from damage that could be limited with better construction.

Feature of the Week

Ground Source Heat Pumps in Schools
By Jim MacMillan, P.E., Member ASHRAE
Ground source heat pump (GSHP) systems in schools provide an excellent source of comfort and partial heating/cooling. According the U.S. Department of Energy, the systems reduce energy use by 25% to 50% compared to traditional systems and result in typical payback periods of two to eight years. This article is a review of various considerations to help guide design professionals when proposing these systems to school boards, parents and others.
