Use of the KOAMS can reduce HVAC operating costs and potential liability resulting from indoor air quality problems.

The Kele Outdoor Air Flow Measurement System (KOAMS) was developed to meet ANSI/ASHRAE Standard 62.1 Ventilation for Acceptable Indoor Air Quality and the energy efficiency requirements of the "green building movement". The KOAMS was tested in accordance with ANSI/AMCA Standard 610-06 and is capable of producing an overall ±0.5% accuracy through the velocity range of 200 to 1,200 fpm and ±5% accuracy at 100 fpm.

The Environmental Protection Agency (EPA) reported that, "the economic losses to the nation due to indoor air pollution are in the tens of billions of dollar per year," and suggested that "modest investments toward improved indoor air quality would generate substantial returns" (Energy Cost and IAQ Performance of Ventilation Systems and Controls, EPA, January 2000). Since the KOAMS has an accuracy of ±0.5%, specifying engineers can be assured that ANSI/ASHRAE Standard 62.1 will be met and that "returns due to improved air quality" may be gained.

The EPA further reports that, "the energy required to run the HVAC system constitutes about half of a buildings' energy cost. Since energy efficiency can reduce operating costs and because the burning of fossil fuels is a major source of greenhouse gases, energy efficiency has become an important concern to the building industry and the promotion of efficient energy utilization has become a matter of public policy."

LEED® Green Building Rating System

The Leadership in Energy and Environmental Design (LEED)® program objective is to encourage the design and construction of buildings that have little or no negative impact on occupants and the environment. The LEED® Green Building Rating System is based on a series of prerequisites and credits.

The KOAMS can be used to fulfill Indoor Environmental Quality (EQ) Credit 1: Outdoor Air Delivery Monitoring for 1 point. EQ Credit 1 requirements state, "For each mechanical ventilation system serving non-densely occupied spaces, provide a direct outdoor air flow measurement device capable of measuring the minimum outdoor air flow rate with an accuracy of plus or minus 15% of the design minimum outdoor air rate, as defined by ASHRAE 62.1- 2004."

Because of the exceptional accuracy of the KOAMS it can also be used to minimize the additional energy consumption associated with higher ventilation rates (30% above the minimum rates) on projects seeking to obtain 1 point for EQ Credit 2: Increased Ventilation and on projects seeking to obtain 1-10 points for Energy and Atmosphere (EA) Credit 1: Optimize Energy Performance.

In addition, the KOAMS can be used to measure the required air volume (14,000 cu. ft. of outdoor air per sq. ft . of floor area) during building flushout to obtain 1 point for EQ Credit 3.2: Construction IAQ Management Plan.
