Energy Recovery Overview

1. Benefits of Energy Recovery Ventilators

   1. Indoor Air Quality

      • The Indoor Air Quality (IAQ) of a building can have potentially harmful, implications for occupants that live, work, or study there every day. IAQ is a measurement of the amount of undesirable substances in the air that can have adverse health effects such as Volatile Organic Compounds (VOC), carbon monoxide, natural gas, mold, and bacteria. The harmful effects that can result from poor IAQ range include:

      • Health and Wellness Effects: Acute allergies, headaches, coughs, asthma, skin irritations, and breathing difficulties, as well as chronic illnesses such as cancer, liver disease, kidney damage, and nervous-system failure.
      
      
      • Cognitive Function Effects: Studies by the Harvard School of Public Health and the Lawrence Berkeley National Laboratory found that carbon dioxide (CO2)-a constituent of exhaled breath-negatively impacted thinking and decision-making at levels commonly found inside homes and buildings.
      
      
      • Productivity Losses: Worker sickness and absenteeism cause serious losses for businesses of every type, which is estimated to cost the U.S. economy $168 billion annually.

      Energy Savings

      • Energy Recovery (ER) media works by drawing heat and moisture from exhaust air and transferring it to an outside air supply. Based on the specific application, the efficiency of this energy transfer can be as high as 80%. Proper application of energy recovery significantly reduces the heating and cooling load requirements for a building's primary air handler, which allows for use of smaller, less costly equipment.
      
      
      • The added cost of the energy recovery unit pays for itself by reducing energy costs. In some instances, paying for itself in only a few months
      
      
      • Meet Design Requirements:
        
        
        • ASHRAE - ER Products can help engineers meet the Guidelines for energy and ventilation in ASHRAE Standards 90.1, 189.1 and 62.1.
        
        
        • LEED - For buildings with LEED requirements, ER Products help to achieve the proper energy efficiencies to acquire LEED Credits in both the EA and EQ categories
