Reflecting a long-established Swedish commitment to environmental stewardship, the Nelson Cultural Center addition at the American Swedish Institute (ASI) in Minneapolis integrates several technically advanced sustainable features, including a high-efficiency geothermal heating and cooling system that reduces energy consumption by nearly 30 percent (based on an ASHRAE 90.1 baseline) while supporting the Institute’s diverse community programming.
When it comes to celebrating the new Exploratorium museum project, located at Pier 15 along San Francisco’s Embarcadero, the engineering and systems design professionals at Integral Group tend to take it a bit … well, personally.
The author’s longtime interest in bundling efficiency techniques in a single system eventually led him to a new pairing: VRF zoning technology and geothermal design. See how he got there and how this couple played out for an historic 107-year-old Iowa courthouse that serves the law through the area’s brutal winters and humid summers.
Take a large hospital, subtract unexamined rules of thumb, add meaningful incremental improvements like VFD’s and a controls upgrade, and what do you get? Smarter engineering via improved performance for both the pumps and the chillers. But it all starts with one little question.
