"Pumps, flues, valves, sizing, maintenance... there's a lot more to consider than just the boiler. Keep the car metaphor in mind, and your next replacement might not drive you to despair."

Supermarkets: A Bellwether of Industry Changes

Air Conditioning, Heating & Refrigeration News, Sep. 7, 2015, by Ron Rajecki.
http://www.achrnews.com/articles/130513-supermarkets-a-bellwether-of-industry-changes

"Supermarkets and their needs will always be one of the front-and-center elements of the HVACR industry. These high-profile businesses operate long hours, use large amounts of energy, and have tens of thousands of dollars in perishable product that needs refrigeration 24/7. Trends in supermarkets can often provide insights into changes to come for the rest of the commercial refrigeration world, and — as is the case industry-wide — refrigerants are on the minds of many in the supermarket sector."

Direct-Fired Technology: From Makeup Air to Space Heating

ASHRAE Journal, Sep. 2015, by Thomas Boeckermann, and others.
http://bookstore.ashrae.biz/journal/download.php?file=2015Sept_016-027_Kuehn.pdf

"Direct-fired heating technology is a safe, energy-efficient, and cost-effective means to provide heating for a wide range of applications. The two main uses—makeup air and space heating—have different applications and require different approaches to deliver the most efficient design. This article summarizes the basic operating principles, safety, energy performance, psychrometric behavior, and recommendations for the use of direct-fired heating units."

Harvesting Energy Savings in Cannabis Cultivation Facilities: Quick Wins for Cultivators and Utilities

E Source, Sep. 11, 2015, by David Podorson.

"With the recent legalization of cannabis in some states, cultivation facilities have rushed to increase production and gain market share, and they have often overlooked energy considerations in the process. Indoor cannabis cultivation facilities are huge energy consumers with year-round loads; each marijuana plant consumes more energy than seven refrigerators, and each cultivation facility may contain up to 400 plants.... Here we present nine tips for quickly and easily reducing the energy consumption of these facilities."

Pond Loop for Ice Refrigeration

ASHRAE Journal, Sep 2015, by Jason Larosh.

2015 ASHRAE Technology Award Case Studies:
"The pond loop geothermal refrigeration system at the Janesville Ice Arena uses an adjacent pond as thermal storage to pull heat from and reject heat to the ice sheet refrigeration system. Other improvements to the arena include a new ice sheet and hot water heating system."

City Sewage Energy Recovery

North American Clean Energy, Jul/Aug 2015, by Erwin Schwartz B.Eng. is the President at DDI Heat Exchangers.
http://www.nacleanenergy.com/articles/20651/city-sewage-energy-recovery

"Municipal wastewater heat recovery is a system in which a heat exchanger transfers heat energy from the sewer waste water to a solution of water and antifreeze (ethylene glycol). A heat pump then uses the heat of this solution to heat buildings, preheat domestic hot water, and heat garages in the winter and also cool the space in the summer."


Combination Ductless Heat Pump & Heat Pump Water Heater Lab and Field Tests

Northwest Energy Efficiency Alliance (NEEA), Aug. 26, 2015, by Energy 350.
http://neea.org/docs/default-source/reports/combination-ductless-heat-pump-heat-pump-water-heater-lab-and-field-tests.pdf?sfvrsn=4

New NEEA Report: "This report summarizes the lab and field test findings for Mitsubishi’s prototype Ductless Heat Pump (DHP) Plus H2O product. This product combines a ductless heat pump with a heat pump water heater into a single, integrated product. Mitsubishi has teamed with a water heater partner for the water heater portion of the product. NEEA has partnered with Mitsubishi to test the appliance and to provide feedback regarding performance. NEEA has selected Energy 350 to conduct the testing and reporting."
