Many utilities are promoting tightly-sealed homes to improve energy efficiency, and it is important to understand the implications of a well-sealed structure on indoor air quality (IAQ). With Electric Power Research Institute (EPRI) support, Energy International conducted a nationwide survey of electric utilities to determine utility understanding of IAQ and ventilation issues. A total of 35 utilities were contacted for this survey. Utilities known to be active in the ventilation area were specifically targeted. The remaining utilities were chosen to gain a balanced geographical and size representation. A survey form was completed for each utility, providing a consistent platform for the survey. The results of the survey indicate a mixed awareness and interest in ventilation issues. Of the 35 utilities contacted, 10 were concerned with IAQ issues and were taking steps to alleviate potential problems through ventilation. Eight of the utilities believed that IAQ issues may be important in the future but have not yet implemented ventilation requirements or recommendations. The remaining 17 utilities did not express a significant concern with IAQ and did not foresee future problems. The utilities surveyed had only moderate concern with detailed ventilation issues such as infiltration measurements, spot vs. Whole house ventilation, source control vs. dilution, and control strategies. The most important utility concerns appear to be questions about the basic need for IAQ controls, and the cost-benefit analysis of energy efficient homes that require additional ventilation equipment. The utilities contacted that are concerned with IAQ generally have several mechanical ventilation system options to meet recommendations.
