Program Entices Energy-Efficiency Retrofit Funding With Returns From Savings
SEATTLE—Private investors, a technology company, a municipal utility and an environment-oriented foundation have joined forces to show that major energy-efficiency improvements in commercial buildings may provide alluring new revenue to all involved. A program at the Bullitt Foundation’s new building in Seattle is aimed at attracting the notice of commercial building owners around the country who may be reluctant to make large investments in such technologies. Under the plan, if investors put in the capital for energy efficiency "deep retrofits," new revenue, based on precise measurements of energy savings, will continue for decades. Seattle City Light, a municipal utility, has agreed to the long-term purchase of energy savings from the Bullitt Foundation, whose new building is lauded for its energy-efficiency features. The savings will be measured by a software program from EnergyRM, using a new kind of power meter that will track and verify how much savings have occurred daily.

DOE Launches U.S. Buildings Database
WASHINGTON—The U.S. Department of Energy (DOE) has launched the Buildings Performance Database, the largest free, publicly available database of residential and commercial building energy performance information. The database will allow users to access energy performance data and perform statistical analyses on more than 60,000 commercial and residential buildings across the U.S. New records will be added regularly. The database includes the buildings' location; age; size and function; electricity and fuel consumption; equipment information and operational characteristics. The data can be used to compare performance trends among similar buildings, identify and prioritize cost-saving energy efficiency improvements, and assess the range of likely savings from these improvements.

European Refrigeration Groups Lobby for Relaxing of F-Gas Elimination Targets
LONDON—European refrigeration industry organizations say they are redoubling efforts to convince European policymakers that the recent decision by the European Parliament ENVI Committee to ban HFCs in new equipment from 2020 is too stringent. The Air Conditioning and Refrigeration Industry Board (ACRIB), the British Refrigeration Association (BRA), the European Partnership for Energy and the Environment (EPEE) and European Refrigeration, Air Conditioning & Heat Pump Contractors (AREA) say that compromise is needed to ensure that the refrigeration, air conditioning and heat pump industry does not bear the brunt of costs for an accelerated phase-down of HFCs and premature new equipment bans in key HVAC&R sectors.

Energy Use Intensity of U.S. Federal Buildings Reduced 25% in Past Decade
WASHINGTON—The U.S. General Services Administration (GSA), which builds and manages federal buildings, recently announced that it cut federal energy spending by $65.5 million in fiscal year (FY) 2012 by reducing the energy use intensity levels in its buildings by nearly 25% since FY 2003. That placed the GSA well ahead of its goal of a 21% reduction in energy intensity.

Solar-Powered 'Sustainable City' in Dubai Progressing
DUBAI, United Arab Emirates—A London-based architecture firm has been chosen to design Phase 2 of the Dubai Sustainable City development. The 114 acre (46 ha) city, as planned by Stringa Planning Studio, will produce most of its own energy with solar panels. Every house in the city will be equipped with solar panels, which will meet 60% of their energy needs. The construction of Dubai Sustainable City is planned over four phases. According to Diamond Developers, about 100 villas and townhouses at the Dubai Sustainable City will be online by the end of 2014. By 2016, the final phase is expected to be complete.

Developing Nations Closing Renewable Energy Gap
NEW YORK—Renewable energy investments are shifting to developing nations as countries from Morocco to Chile pursue power sources that wean them off fossil fuel imports, two studies promoted by the United Nations said. China’s total of $67 billion of investments in wind, solar and other renewable projects led developing nations to $112 billion of spending in 2012, according to a statement today from the U.N. and other groups involved in the studies. That compares with $132 billion in expenditures in the industrialized world. The gap in spending on renewables between richer and developing countries shrank to 18% last year from 250% in 2007, marking a “dramatic change” in investment patterns, the statement said. Two-thirds of the 138 nations that now have clean-energy targets are in the developing world.

ASHRAE Launches Online Discussion Platform
ASHRAE has developed an online platform for its members and others in the HVAC&R industry to engage in real-time discussion and information exchange for design, construction, operation and support of the built environment. The platform, at www.ASHRAExCHANGE.org, was launched at the 2013 ASHRAE Annual Conference in Denver, which ended June 26. Anyone with access to the Internet can view posts, comments and messages on the ASHRAExCHANGE at any time. Neither registration nor special software is necessary, as the platform is Web-based. With thousands of ASHRAE members and nonmembers checking the ASHRAExCHANGE 24/7, the hope is the online discussions will generate plenty of thoughts and comments from many knowledgeable people, according to Spencer Morasch, incoming chair of ASHRAE’s Electronic Communications Committee.

Feature of the Week

Total Energy Wheel Control in a Dedicated OA System
By John Murphy, Member ASHRAE
With increased focus on reducing energy consumption in buildings, the use of exhaust-air energy recovery in HVAC systems is becoming more common, somewhat prompted by requirements contained in ASHRAE standards. Proper control of the energy-recovery device is critical to realize the expected energy savings. The focus of this article is on proper control of a total energy wheel (or enthalpy wheel) when applied in a dedicated outdoor air system (DOAS). This article earned the author the Journal Paper Award, presented at the recently concluded 2013 ASHRAE Annual Conference.

This article originally was published in March 2012. Click here to download the article. It will be available here through July 12.

After July 12, access to the article from this eNewsletter will no longer be available. It will remain available for free download by members here and for purchase by nonmembers in the ashrae.org online store.
