Commercial Building Industry Trending Toward 'Green'
RICHARDSON, Texas—The commercial building industry is moving toward greater transparency, higher energy-efficiency requirements, increased sustainability and more responsible use of building materials, according to Lennox. The manufacturer foresees a number of trends leading to a $280 billion global growth in the green building sector by 2020. Among the top trends identified by Lennox are increased visibility and a greater push for net zero energy projects. Lennox says that high efficiency designs are a way buildings industry professionals and companies can differentiate themselves, and transparent declarations of efficiency and environmental friendliness increase their image in the competitive buildings industry. To lower costs, companies are turning to cheap, yet effective measures, such as alternative energy and daylighting. However, Lennox says that HVAC, which accounts for 40% to 60% of building energy use, is "an obvious first item to tackle in greening efforts."

Visiting Earth's Coldest City
YAKUTSK, Russia—Fish markets in Yakutsk, Russia, are literally open as the outdoor air is so cold the fish remain frozen in open crates. When a Swiss photographer visited the Russian city in January, the temperature was –48°C (–54°F). It was so cold his camera froze. With a lowest recorded temperature of –64°C (–83°F), it is the coldest city in the world. However, the city is far from desolate. With a population of 270,000, it is the largest city in Siberia. However, Yakutsk isn't always cold. Despite being covered with a layer of permafrost, it heats up in the summer, with a record high of 38.4°C (101°F).

Students Without AC Learning to Beat the Heat in Chicago

CHICAGO—The brutal heat in Chicago has prompted some schools to end classes early this week, or cancel classes altogether. Other schools, particularly in suburban districts, are trying to keep cool without the benefit of air conditioning in the classroom. Keeping the lights off, fans on and water breaks frequent are just some of the strategies being used to keep thousands of students comfortable. Other coping measures include rotating students into air-conditioned libraries or computer labs to cool off. "It is a bit of a distraction because you're trying to get your school year going," said one local school official. "But there's nothing you can do." Some Chicago schools, because of their age, cannot support window AC units or be retrofitted for full AC. Recent temperatures in Chicagoland have been around 95°F (35°C). When combined with humidity, it has felt as hot as 103°F (39°C).

Nordstrom Spearheads Development of 1,550 ft NYC Skyscraper
NEW YORK—Nordstrom has paid $102.5 million for its future Midtown Manhattan store to become the anchor of a 1,550 ft (470 m) tower that is under development. The store, Nordstrom's first in New York City, will occupy the first seven floors of an 88-story tower that will be taller than the 1,454 ft (443 m) Empire State Building. The deal also would give Nordstrom control of the site should something go awry with its development. The store is scheduled to open in 2018.

LED Lighting Market Could Grow by Tenfold By 2021, Says Report
BOULDER, Colo.—According to a recent report from Navigant Research, revenues from LED lighting products (including lamps and luminaires) in commercial building markets will grow from $2.7 billion in 2013 to more than $25 billion in 2021. “While other lighting technologies have limited potential for future improvements, new designs for LEDs that push quality and efficacy to new levels continue to emerge from lighting labs around the world,” said Jesse Foote, research analyst at Navigant Research. In the coming years, LED prices are expected to fall to a point where savings from electricity consumption will provide a short payback period that will encourage consumer adoption en masse, according to the report.

ASHRAE, IBPSA-USA to Jointly Host Building Simulation Conference
ASHRAE and IBPSA-USA will jointly host a conference that merges the IBPSA-USA SimBuild and ASHRAE Energy Modeling Conferences. The 2014 ASHRAE/IBPSA-USA Building Simulation Conference is intended to improve the industry’s ability to accurately model building performance. It will be held Sept. 10–12, 2014, in Atlanta. The conference has a theme of "BIM, BEM and SIM—Integrated Building Design and Modeling,” addressing building information modeling, building energy modeling and building simulation. Organizers are seeking papers on topics addressing the integration and interoperability of analytic modeling tools (BEM and SIM) with physical modeling tools (BIM). In addition, papers are sought describing workarounds, case studies, challenges, barriers and cloud-based solutions. Abstracts (400 or less words in length) are due Nov. 4, 2013. If accepted, papers are due March 3, 2014. The conference papers will be a maximum of eight pages in length.

Feature of the Week

Water-to-Water Heat Pumps
By Roy Hubbard, Member ASHRAE
Many owners and designers of large commercial, institutional, and industrial (CII) facilities are considering the economic and environmental benefits of a water-to-water heat pump as a supplement to, or substitute for, a fossil fuel boiler. While a typical hot water boiler has a coefficient of performance (COP) of 0.85, heat pumps can have COPs of 3.50 or higher, which makes a compelling case for including heat pumps in many facilities. This article discusses several system design guidelines, energy consumption calculations, green technology benefits, and capital constraint solutions.

Boilers From AERCO
BLAUVELT, N.Y.—AERCO International introduces the Modulex EXT series of condensing and fully modulating boilers for a variety of light commercial and commercial applications. Designed for hydronic heating systems, units operate from 321 MBH to 1,123 MBH (3150 kW to 11 017 kW) and have turndown of up to 24.5:1. The boilers achieve high performance due to a unique design that incorporates multiple high-capacity, low emissions burners. Each 160,500 Btu/h (4700 W) thermal module operates independently to increase turndown range, and the simultaneous low-fire operation design helps maximize operating efficiency.
