USP 800 Pharmacy HVAC Testing – The Devil is in the Details: Part 1

Posted by Matt Napolitan on Oct 23, 2019 10:00:00 AM

A large healthcare client of ours recently opened a brand new USP 800 compliant compounding pharmacy, which we commissioned. We collaborated with the engineering team and the hospital during the design phase to help ensure prior issues weren’t repeated, and the hospital’s concerns were thoroughly articulated and addressed. At the conclusion of the design phase, the team was confident that the design direction was solid and would give the hospital what they were looking for.

Understanding the Basics of a Ground-Coupled (Closed Loop) Heat Pump Design: Part 1

Posted by Tate Colbert on Oct 9, 2019 10:00:00 AM

The ground source heat pump is a wonderful technology that will be vital in achieving energy efficiency goals this century. This technology isn’t new, but it is beginning to become more accepted as a viable solution for large scale, high efficiency HVAC performance. There are two main types of ground source heat pump systems: those that are “Ground Water” (also called Open Loop) and those that are “Ground-Coupled” (also called Closed Loop), see Figure 1 below. In either case, the water from the ground is pumped to a heat pump, where heat is either extracted out of or rejected into the ground and moved into or out of the conditioned space.

Occupant Based Controls for Energy Savings

Posted by Daniel Tuhus-Dubrow on Jul 3, 2019 10:00:00 AM

I recently attended the Performance Evaluation Methodology for Building Occupancy Sensing Systems for HVAC Controls workshop, which followed the annual ASHRAE conference that just wrapped up in Kansas City, MO. The workshop focused on one of ARPA-E’s[1] research programs called SENSOR (Saving Energy Nationwide in Structures with Occupancy Recognition)[2], and brought together a diverse group of individuals, including researchers from national labs and universities, industry representatives, design engineers, and other interested parties.
