Efficiency: It’s All In the Installation

February 3_NIST Quality HVAC Report ImageA recent National Institute of Standards and Technology (NIST) report proves that HVAC equipment requires a quality installation (QI) in order to perform at its rated efficiency. The report, “Sensitivity Analysis of Installation Faults on Heat Pump Performance,” shows design and installation deficiencies contribute directly to a rise in energy consumption.

The report is based on a three-year study that focused on how the building, equipment and climate affect HVAC performance. The following installation faults were found to have the largest potential impact on efficiency:

  • Duct leakage
  • Low indoor airflow
  • Refrigerant undercharge or overcharge
  • Oversized equipment with undersized ductwork
  • If two or more simultaneous faults occur, the loss of efficiency and amount of energy consumption risk amplification

A QI requires high-efficiency products, correct design, proper installation and accurate field measurements. To help ensure these components are met, the ANSI/ACCA 5 QI Standard specifies what to measure, how to measure and the measurement tolerances necessary for unitary residential and commercial HVAC systems.

We recognized that a successful, sustainable installation not only requires a high-performing product but top-notch service as well, which is why we created the Diamond Dealer™ program more than 10 years ago. This elite group is the most extensive, highly-qualified contractor network in the industry today. Through demanding certification and continuous education, our Diamond Contractors™ ensure that our energy-efficient products perform at their industry-leading efficiencies.

ASHRAE, NAHB and ICC Combine Forces to Develop New Green Building Standard

April 9_3 logos
The National Association of Home Builders (NAHB) announced last month that ASHRAE will join forces with the association and the International Code Council (ICC) to develop the 2015 ICC/ASHRAE 700 National Green Building Standard (NGBS). This marks the third adaptation of the standard and the first time that ASHRAE has partnered on its development. As long-time advocates for green building, we’re thrilled to see ASHRAE team up with the NAHB and the ICC to both advance and promote the values of sustainability.

A joint NAHB and ICC committee first developed the NGBS in 2007. The committee included home builders, code officials, product manufacturers, government representatives and building science and energy-efficiency specialists. The American National Standards Institute (ANSI) approved the standard in 2009 as the first green standard for residential construction, development and remodeling. The NGBS was updated in 2012 and since then has been used to certify more than 32,000 residential constructions. In fact, the NGBS now serves as the leading standard in the industry for sustainable home building, a growing trend in the U.S. market and a sector that is expected to represent as much as one third of the building market by 2016.
