"Leaning on experience and data from various K-12 cities and projects, the authors pursue some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll."

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."

Tacoma Power Ductless Heat Pump Proposal Changes Washington State Energy Code

Northwest Public Power Bulletin, Apr. 2016, by Sonja Bert. -- scroll or jump to page 14.

"An energy audit of the medical center's equipment, processes, and systems identified a number of operations and maintenance improvements that could add up to significant energy savings."

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?"

Evaluating Chilled Water Cooling System Components

Chiller & Cooling Best Practices, May 2016, by Joe Leichner.
http://www.coolingbestpractices.com/technology/chillers/chillers-and-cooling-systems-weec-2015/evaluating-chilled-water-cooling-system-c

"While the chiller is the heart of a chilled water system, its support system of components and controls are equally critical to maintain and manage to ensure the highest system efficiency levels are attained. Emphasis is often placed on the chiller since it is the most visible and typically the highest energy element of a chilled water system. Yet, if you look beyond the flanges, there’s an opportunity to improve delivery of chilled water to the airside or process loads and maximize system efficiency."

The Water Energy Nexus: Business Risks & Rewards

Pumps & Systems, May 2016, by Jessi Tseng.
http://www.pumpsandsystems.com/pumps/may-2016-water-energy-nexus-business-risks-rewards

"Increasing demand and competition for water and energy have implications for many of the world's largest industries. Energy utilities and producers of metals, chemicals, oil, gas and coal are the most energy- and water-intensive industries.... New ideas and approaches will be necessary to ensure sustainable resources in the future."
