Zeroing In [on Zero Energy]

Building Science Insights, Building Science Corporation, by Joseph Lstiburek.
http://www.buildingscience.com/documents/insights/bsi-081-zeroing-in/

"So what does “net zero” mean anyway? And what is the difference from a “zero energy house”? A zero energy house is “off grid” and makes all the energy it needs on site using renewables. This is not easy to do and typically involves an ultra efficient house and energy storage. Good luck. Having said that, I like the ultra efficient part. I can’t help it. Engineers worship efficiency. The storage part worries me."

"Industries that must treat or pretreat their wastewater face varied challenges. Any given facility’s needs are best met by a total systems approach (TSA) — a fully integrated solution that includes all pieces of the puzzle instead of uncoordinated components and systems. The approach includes a collaborative evaluation up front to understand a facility’s requirements, apply proven designs and materials, and select innovative products that achieve the optimum water quality at the best life cycle cost."

"When the topic of discussion is making ice cream, the first thing that comes to mind isn’t heat, but at Nestlé’s Ice Cream factory in Tulare, California, heat is recovered from air-cooled air compressors to heat process water."

Airside Economizers For Indoor Pools

Engineered Systems, Oct. 2014, by Patrick J. Reynolds.
http://www.esmagazine.com/articles/96785-airside-economizers-for-indoor-pools

"Sometimes it’s less important to think outside the box than to notice that the stuff inside the box has changed. In the case of airside economizers, more modern components and seasonal opportunities can make things work swimmingly."
