Q: How long has PaceControls’ PACE3 product suite been in operation?
   PaceControls, an ENERGY STAR PARTNER and DOE and Ben Franklin Technology Partners funded company, commenced operations in 2005 to develop energy efficiency and smart grid HVACR (heating, ventilation, A/C and refrigeration) retrofit solutions to make existing heating, cooling, and selected refrigeration equipment more efficient.  Over 15,000 units of our award-winning product suite have been deployed, and PaceControls is proud to be a DOE grant award winner and part of the DOE-funded Consortium for Building Energy Efficiency at the Philadelphia Navy Yard, a national center for building efficiency and smart grid innovation.


Q:  What kinds of HVACR equipment can use PACE3 retrofits?
A:  Over 60 IPMVP-compliant metered trials, independent testing, and controlled lab testing 2005-14 have shown the patented and UL Listed PACE3 product suite to be suitable for a wide range of HVACR equipment.  The PACE3 line was designed with significant input from the HVACR industry, to provide a highly flexible retrofit solution to a wide range of HVACR equipment.  Primary applications are with positive-displacement (non-centrifugal – e.g. scroll, reciprocating, and screw compressor) air conditioning and refrigeration units from 3 up to about 100 tons, although in joint product development with a global OEM, PACE3 retrofits have shown good results even on residential-scale SEER 15+ equipment.  In heating, non-condensing gas- and oil-fired boilers and furnaces with AFUE ratings less than 92 are generally excellent candidates.  PACE3 retrofits also can be very effective with heat pumps, and another significant “sweet spot” application is rooftop gas/electric or electric/electric package units.  A qualified HVACR technician or building engineer, in communication with PaceControls if necessary, can determine appropriate applications.

Q:  What are the requirements for an installation?
A:  PACE3 retrofits can be installed on a very wide range of HVACR appliances that are in good working order, by a qualified HVACR technician and in compliance with PaceControls technical documentation and support.

Q:  Why must the installer be a qualified HVACR technician?
Installation is quick and relatively straightforward in most cases, but knowledge of HVACR control circuitry is important, and use of qualified HVACR technicians assures that the PACE3 retrofit is installed properly, in the right applications (and in properly functioning equipment), to assure both savings and full equipment operating performance.

Technical Operation

Q:  How is what PACE3 retrofits do, different than a building-wide monitoring and control system?
A:  PaceControls retrofits are compatible with all building-wide management systems (BMS), and most current PACE3 installations are in buildings that have some form of BMS.  Most BMS systems are designed to allow such benefits as remote thermostatic control with setbacks, equipment run time normalization, monitoring and reporting, online diagnostics, prevention of harm from poor electricity quality, and similar features.  These, of course, are all valuable.

In contrast, PACE3 technology is focused at the “foundation” of building energy consumption, by improving the energy efficiency of the compressor cycle (in the case of cooling or refrigeration systems) and/or thermal energy source (in the case of heating systems).  Thus, it operates “below” the BMS level, but quite compatibly and visibly with it, and with easy interconnection.


Q:  How do PACE3 retrofits save money?  Are incentives available?
A:  In all applications, PACE3 retrofits reduce energy consumption (kWh and therms), and save the operating cost of the saved energy.   In cooling and heat pump applications, PACE3 retrofits can also reduce time-average demand (kW) substantially, as a PDR (permanent demand reduction) EEM, providing additional savings from reduced demand charges.  PACE3 is eligible for both electric (both kWh and kW) and gas energy incentives, generally anywhere such incentives are offered.
