HVAC Retrofits

VRF Heat Pumps In The Real World

Wide temperature swings, submetering deficiencies, bloated carbon footprint … these are but three of the problems tackled in two contrasting projects in the Northwest.
How is variable refrigerant flow (VRF) working for you? We asked a number of people that question and summarized the findings from two typical facilities here.

Editor's Note

A Plan And A Plant

A philosophy plus the usual opportunities made for real savings. What about where you work?
Since energy efficiency is a big part of what this industry pursues on behalf of society at large, I always like to see examples of what companies and firms are doing internally to conserve resources. This month, A.O. Smith celebrated progress on that front at its plant in McBee, SC.

The (Cost) of DOAS/Radiant

If a design team is lucky, it faces a system choice between “good” and “very good.” However, it’s not always simple to tell which is which.
Engineers are rethinking the standard engineering design paradigm, using lifecycle cost analysis (LCCA) to compare system alternatives that fulfill the same functional requirements but differ in terms of initial and operating costs.

A Lesson Plan For Sustainability

The Medical University of South Carolina implemented broad energy efficiency im-provements without incurring capital costs.
Today, many state institutions of higher learning and healthcare facilities face reduced budgets, aging infrastructure, and rising energy costs. According to the EPA, colleges and universities spend close to $2 billion each year on energy. These institutions are seeking innovative ways to renew facilities, improve energy efficiency, and reduce energy costs. One option gaining some renewed momentum is the Energy Savings Performance Contract (EPSC).

The Challenges Of Federal Government Procurement

With a collaborative design approach and the choice to forego networking protocols, this nuclear facility’s controls upgrade points toward an atypical alternate for success.
The procurement process used by the U.S. government (or its contractor) can follow one of several different paths. Usually, an equipment specification is written that contains performance criteria and other requirements. A solicitation is then released and potential sellers competitively bid for the work.
