Commissioning and Design for 2016 Olympics

ASHRAE Journal, Jul 2016, by Ross D. Montgomery and Walter R. Lenzi.
http://bookstore.ashrae.biz/journal/download.php?file=2016July_014-019_Montgomery.pdf

"Beginning in 1994, the International Olympic Committee began to require environmental awareness as part of all Olympic Games. Over the years, the emphasis on sustainability grew, and the Rio 2016 Olympic Games in August is the latest example of the benefits gained by using these strategies. ASHRAE members and student members are a part of this high-profile project, as they provided commissioning and HVAC&R design services, especially at the Olympic Park. This venue is where most events will occur in Barra da Tijuca, located 21 miles (34 km) south of Copacabana beach."

New Heat Pump Water Heater Changes the Game

Northwest Energy Efficiency Alliance, July 2016.
http://neea.org/neea-newsroom/press-releases/press-release-detail/2016/07/05/new-heat-pump-water-heater-changes-the-game

"Today, A. O. Smith, the largest manufacturer and marketer of water heaters in North America, introduced a dramatically efficient new model of heat pump water heater. Already three times more efficient than a standard electric water heater, A. O. Smith engineers refreshed the Voltex line to improve energy efficiency benefits and performance for homes in all climates, including homes that routinely deal with cold weather."

Think Outside the Troffer

"Upgrading outdated, inefficient troffer lighting is not as complex or costly as you think."

Reducing Energy Consumption with High-Temperature Heating and Ventilation

The Construction Specifier, May 2016, by Marc Braun.

"The Department of Energy published a study, “Field Demonstration of High-efficiency Gas Heaters,” where it discussed how high-temperature heating and ventilation (HTHV) direct gas-fired heaters dramatically reduce energy consumption when replacing unit heaters in warehouses and other high-bay buildings. These direct-fired technologies—often referred to as ‘make-up air heaters’—have been widely adopted as high-efficiency ventilation units. The surprising thing is specialized versions of these products can accomplish high-efficiency space-heating when ventilation is not required, such as during unoccupied times."

Efficiency Is Only the Start: Technology, Design Advances Are Driving High-Performance Lighting

"High-performance lighting designs aim to satisfy occupants while they slash energy use."

Applying Combined Heat and Power Systems

Consulting-Specifying Engineer, June 2016, by Rodney V. Oathout.

"Cogeneration systems, often referred to as combined heat and power (CHP) systems, generate both electricity and thermal energy. As they become more common in the United States, engineers must understand the nuances and design strategies for successful application."

Replacing a Steam Boiler

Engineered Systems, Jun 2016, by Ray Wohlfarth.

"When designing or replacing a low pressure steam boiler, throw out everything you know about hydronic boilers. A steam system is closer in operation to an air conditioning unit than it is to a hydronic boiler. If you design a steam system using hydronic design methods, it will not operate properly. A hydronic system uses sensible heat while a steam system uses both sensible and latent heat. Sensible heat can be measured with a thermometer while latent heat causes a change of state and cannot be measured accurately with a thermometer. The following are some of the steps I take when designing a replacement steam system."

What Matters When Purchasing a Small Wind Turbine?

Solar Today, Spring 2016, by Mick Sagrillo.
http://solartoday.org/2016/05/what-matters-when-purchasing-a-small-wind-turbine/

"What makes a manufacturer worth considering? With the plethora of small wind web sites out there, it’s might seem daunting to try to ferret out the wheat from the chaff, who is a legitimate small wind manufacturer and who is a huckster. Actually, it is simpler than it appears. Remember the discussion about turbine certification? (ST Winter 2015/2016) This is your screen. Any manufacturer not listed with a certified turbine should not be considered, period. No matter what they promise or how much they plead. Do you want to be someone’s beta test site or do you want a working wind system for decades?"

Energy Efficiency in Commercial Tenant Spaces - A Feasibility Study

U.S. Department of Energy, Apr. 2016.
http://energy.gov/eere/buildings/downloads/energy-efficiency-separate-tenant-spaces-feasibility-study

"While commercial building owners generally have control over building systems and operations, tenants play a critical role in achieving lasting reductions in energy intensity. In recognition of this collaborative role, the Department of Energy has studied the feasibility of improving energy efficiency in tenant spaces. This study finds significant potential to improve energy efficiency during the design and construction of tenant spaces and describes several possible steps to encourage owners and tenants to improve the efficiency of those spaces."

ASHRAE Research Outlines Measures to Reach Toward Net Zero Energy

Engineered Systems, Apr. 26, 2016.
http://www.esmagazine.com/articles/97706-ashrae-research-outlines-measures-to-reach-toward-net-zero-energy

"Thirty specific energy savings measures across all building types and climate zones resulted in cutting energy use by nearly half, according to results of newly approved research funded by ASHRAE."
