Energy Dept. Announces $19 Million in Building-Efficiency Investments

Heating, Piping, Air Conditioning, Jun 2016.
http://hpac.com/archive/energy-dept-announces-19-million-building-efficiency-investments

"The U.S. Energy Department recently announced it is investing $19 million in advanced building technologies intended to lower utility bills, reduce greenhouse-gas emissions, and create jobs."

Lunching and Learning: Food for Thought on a Geothermal-Heat-Pump-System Design

Heating, Piping, Air Conditioning, Jun 2016, by Jeffrey Newcomb.

"In the article, Fred, a mechanical engineer, explains his unusual design for a campus chilled-water system to William, a civil engineer. William asks questions and makes observations, system diagrams scribbled on napkins are exchanged, and Fred is left with a new way of thinking about his design. Sound familiar?"

Puget Sound Energy Launches 'Urban Smart Bellevue' Energy Efficiency Program

A project of the Northwest Energy Efficiency Council, the Smart Building Center (SBC) is hosting a "Tool Lending Library". The diagnostic tools are available to building owners and managers, as well as energy service professionals, for short term data collection on energy using equipment and systems in commercial and institutional buildings in Washington.

Commissioning and Design for 2016 Olympics

ASHRAE Journal, Jul 2016, by Ross D. Montgomery and Walter R. Lenzi.

"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."

Reducing Energy Consumption with High-Temperature Heating and Ventilation

The Construction Specifier, May 2016, by Marc Braun.
http://www.constructionspecifier.com/reducing-energy-consumption-with-high-temperature-heating-and-ventilation/

"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."

Replacing a Steam Boiler

Engineered Systems, Jun 2016, by Ray Wohlfarth.
http://www.esmagazine.com/articles/97773-replacing-a-steam-boiler

"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."
