Omaha, NE (PRWEB) January 07, 2014

Bes-Tech, developer of the Digi-RTU, the most innovative and energy efficient aftermarket rooftop HVAC unit control package on the market, announce electrical energy savings of 65% and 68% during an independent energy study by Efficiency Vermont, with additional funding support contributed by the Burlington Electric Department.

Burlington Electric partnered with a local contractor and Vermont Energy Investment Corporation, a tenant in a 51,000 square foot office building located in Burlington, Vermont. The study results reported metered and calculated electrical savings of 65%.

Efficiency Vermont partnered with a local contractor and Vermont Country Store; a 170,000 square foot retail distribution center located in North Clarendon, Vermont. The study results reported metered and calculated electrical savings of 68%.

For each building, one rooftop unit was metered for two weeks before the Digi-RTU was installed and metered for two weeks after the Digi-RTU was installed. Measurement and verification activities as well as analysis were managed by Efficiency Vermont.

The Digi-RTU, winner of the 2011 American Public Power Association’s DEED Energy Innovator Award, is the most innovative and energy efficient rooftop HVAC unit control package on the market. The Digi-RTU has a proven track record of reducing energy consumption and demand by up to 65% with a typical ROI of 1 to 3 years. The Digi-RTU is a simple plug-n-save solution for existing RTU which allows building owners to increase efficiency of older rooftop units without the expense of replacing them.

  • Reduced electricity consumption up to 65%
  • Reduced peak electricity demand up to 65%
  • Reduced compressor on/off cycling up to 75%
  • Improved equipment life span
  • Reduced equipment noise
  • Improved temperature and humidity control
  • Improved CO2 based (greenhouse gas) demand control

The Digi-RTU is the only product on the market that addresses each area identified by the Pacific Northwest National Laboratory (PNNL) to maximize electricity consumption and demand reduction. The Digi-RTU integrates with the existing economizer, modulates the supply fan, modulates the compressor speed, and regulates the indoor air CO2 level. By intercepting heating and cooling calls, the Digi-RTU’s patented technology manages the compressor and fan speeds to match the space requirements. As a result space temperature and humidity are best managed.
