Energy Newsbriefs Blog

The WSU Energy Program Library prepares this current awareness blog with funding from the U.S. Department of Energy State Energy Program. These articles highlight energy-related news, articles, and reports about energy efficiency, energy conservation, and renewable sources of energy for energy professionals and interested members of the public.

Fan-Efficiency Metrics

HPAC Engineering, May 2015, by Dustin Meredith and Jeanne Harshaw.
http://hpac.com/iaq-ventilation/fan-efficiency-metrics

"Air Movement and Control Association (AMCA) International estimates fans account for 30 to 40 percent of commercial-building HVAC energy consumption. Improving fan efficiency, therefore, is an important step toward reducing global, overall energy use."

Balancing Hotel Energy Use and Guest Comfort

"Though hotel guest rooms may hold great potential for cost savings, concerns about the impact of energy-efficiency initiatives on customer satisfaction have kept many hoteliers from investing in energy-management solutions. With recent advances in building-management systems (BMS) and sensors, however, the balance between energy savings and guest comfort easily can be struck."

Congress Creates Tenant Star But Does Little Else

Green Building Law Update, Apr. 26, 2015, by Stuart Kaplow.

"The Energy Efficiency Improvement Act of 2015, S. 535, a portion of this bill was formerly known as the Better Buildings Act of 2015, passed the House of Representatives last week and on April 23rd was presented to the President for signature. ...[this]bill has no mandates and only requires the federal government (and no one else) to undertake some very modest, low cost, acts.  Senate bill 535 requires the General Services Administration to develop and “publish” model leasing provisions to encourage building owners and tenants to use greater cost-effective energy efficiency and water efficiency measures in commercial buildings; and, develop policies and practices to implement the measures for the realty services provided by the GSA to agencies."

Commercial New Construction Market Assessment

Northwest Energy Efficiency Alliance (NEEA), Report #E15-289, May 20, 2015.
http://neea.org/docs/default-source/reports/commercial-new-construction-market-assessment.pdf?sfvrsn=4

"The report highlights trends, barriers, and opportunities for high-performance projects, with a focus on Oregon, Washington, Idaho, and Montana. This 2014 study discusses potential intervention strategies to increase adoption of new design and construction best practices for high-performance commercial buildings. CLEAResult led this project - which includes literature review, market data and stakeholder interviews - with additional support from New Buildings Institute."

Methods of Calculating Water Recovery From Air-Conditioning Cooling Coils, Part 2 of 2

HPAC Engineering, May 2015, by William G. Acker.
http://hpac.com/air-conditioning/methods-calculating-water-recovery-air-conditioning-cooling-coils-part-2-2

"Last month, in Part 1 of this article, we evaluated four equations used to determine the amount of water vapor removed from cooling coils in condensate-recovery applications. The accuracy of those equations varies, as some calculate only the removal of water vapor entering with the outside-air intake. This month, we will discuss more-accurate methods of calculating water-vapor removal and calculating the removal of all water-vapor loads by a cooling coil."

Methods of Calculating Water Recovery From Air-Conditioning Cooling Coils, Part 1 of 2

HPAC Engineering, Apr. 2015, by William G. Acker.

"In traditional building cooling, air passes through chilled cooling coils in air-handling units prior to entering a facility. As air passes over the coils, moisture in the air condenses into water on the coils. The water drips into a collection pan below and is sent to a sewer drain. Today, however, particularly in areas where water is scarce and rates are high, many building owners are collecting this water and using it to replenish cooling towers for irrigation and other uses."

LED vs. Induction Lighting: Which Illumination Solution is Right for Your Facility?

Buildings, Apr. 2015, by Janelle Penny.
http://www.buildings.com/article-details/articleid/18718/title/led-vs-induction-lighting.aspx

"Time for a lighting upgrade? You may be torn between LED and induction fixtures. Both offer low maintenance needs, are compatible with a variety of applications, and can secure energy savings. Familiarize yourself with the basics of these technologies to uncover which one will bring your project to light."

Getting to Outcome-Based Building Performance Event Report

New Building Institute, May 2015, by Mark Frankel and Jim Edelson.
http://newbuildings.org/performance-outcomes-event-report

"This report summarizes the work undertaken by a group of building industry thought leaders who gathered for a Performance Outcome Summit in August 2014 in Seattle, Washington. During a day and a half workshop, the group examined the opportunities, barriers and next steps that will transition the commercial building industry from estimating energy use, based on models in the design phase, to measuring real performance outcomes, based on actual energy use in an occupied building."

Selecting a Boiler for Heating, Process Loads

Consulting-Specifying Engineer, Apr. 2015, by Bradley A. Pankow.
http://www.csemag.com/single-article/selecting-a-boiler-for-heating-process-loads/346ed587852de8e21b053c91f7ec85d5.html

"Boilers for heating and domestic hot water systems are used in many nonresidential buildings and across educational, hospital, and industrial campuses. This article reviews the codes and standards that regulate boiler system specification and design, plus energy efficiency and efficacy of these boiler systems."

Integration: Lighting and HVAC systems

Consulting-Specifying Engineer, April 2015, by Chris Rush.
http://www.csemag.com/single-article/integration-lighting-and-hvac-systems/74d81a6dede2cff0f4dd8a689c13ad76.html

"By considering the first principles of radiative energy, engineers can determine how to balance daylight, electric light, and HVAC systems, particularly considering various options for daylight control and the advent of LEDs."
