For the massive 235,000-sq-ft Merrimack County Nursing Home in New Hampshire, the geothermal source available nearby may not have been the fountain of youth, but it did prove key to the center’s “uber-green” mechanical system retrofit. See how the companies involved brought together 16 wells, over 300 water-to-air heat pumps, and the rest of the 615-ton system to serve this 290-bed facility.
Two engineers mine their collective experience for tips on designing, modeling, and operating hydronic radiant heating and cooling systems. From conceptual basics to control nuances, on to goals like maximizing deadband operation or deploying a hybrid system, the article circulates plenty of practical information for an array of radiant opportunities.
Critchfield Mechanical, Inc. an HVAC engineering firm in Menlo Park, CA needed a cost-effective and energy-efficient perimeter zone ventilation solution.
Word of mouth is a potent ingredient in craft brewing, the fastest-growing segment of U.S. beer making. Defined as producers of fewer than 6 million barrels annually, craft brewers tend to share best-practice tips with the same enthusiasm that beer lovers have for the unique brands and flavors they create.
In which the author lays out the path from earlier data center design to a more recently discovered airflow challenge. Read on for his insights on how to keep positive differential pressure from being a negative for your facility’s energy budget.
Data center HVAC has come a long way since ’80s-era strategies and even since turn-of-the-century room parameters. Consider that evolution, and how options like economizers and evaporative cooling may be more appealing in light of wider environmental envelopes.
The students have changed, and the way spaces get used is changing as well. How do we need think about educational environments to foster better thinking inside them?
The author's firm recently explored three options for use in buildings that are “user-friendly” when dealing with the highly variable load demands of multi-tenant occupancies, often requiring simultaneous space heating and cooling requirements. Read on to see what they found out about performance and life-cycle cost for their client.
