3 Options for HVAC Energy Savings

Building Operating Management, June 2015, by James Piper.

"Even with today’s falling energy prices, facility managers are looking for ways to reduce the energy use of HVAC systems. New technologies and improvements in existing technologies are giving facility managers options. While advances can be seen in practically all HVAC systems, some of the most significant advances are coming in three particular areas: variable refrigerant flow systems, rooftop units, and geothermal systems."

Is VRF Right for Your Next Project?

Consulting-Specifying Engineer, June 2015, by Amara Rozgus.

"Variable refrigerant flow (VRF) systems can be specified into a variety of buildings, especially those that require flexibility. An overview of these systems and some best practices have been provided by Julianne Laue, PE, LLED AP BD+C, BEMP, senior energy engineer at the Center for Energy Performance, Mortenson, Minneapolis."

VRF with Heat Recovery Ventilation In Pre K-12 Schools

Engineered Systems, May 2015, by Robert G. Thompson.

"As the learning curve for VRF continues, it’s only fitting to see how it can fare in a familiar learning environment. Turns out it can play a key role in the critical lesson of adapting to existing spaces and occupancy needs when crafting the optimum retrofit design for a given client."

Variable Refrigerant Flow [VRF] Is Evolving

Engineered Systems, Feb. 2015, by Marcia Karr.

"While mechanical energy codes may lag relative to the efficiency targets of some other codes, the expansion of VRF into a wider range of equipment makes it easier than ever to exceed expectations. Perhaps more importantly, its incorporation into heat pumps, dehumidifiers, compressors, and more represents more flexibility in delivering an effective retrofit without a total system overhaul."

Variables for Retrofitting with VRF

Buildings, Jan. 2015, by Chris Olson.

"If you’re considering a major retrofit of an existing HVAC system, take these three steps to do your due diligence for a possible VRF [variable refrigerant flow] solution, says Anne Wagner, energy efficiency engineer at the Pacific Northwest National Laboratory (PNNL)." Also, gives a 15-year lifecycle cost analysis comparison between VAV and VRF retrofit alternatives.
