As energy efficiency reduces the hours where air conditioning is called for, and as codes require outdoor air to be brought into homes, humidity levels in homes may rise to the point where dehumidification is required. However, there are currently no standards in Florida's Energy Conservation Code for dehumidification. Thus, a mechanical contractor that invests in an expense such as variable speed heat pumps or heat pipe technology in order to dehumidify and save energy receives little benefit relative to another home that installs an inefficient dehumidifier. A reference home dehumidification strategy needs to be established.Another strategy to reduce interior …

ASHRAE Standard 62.2, 'Ventilation and Indoor Air Quality in Low-Rise Buildings,' is the most commonly referenced residential ventilation standard in the United States. It is currently required by ENERGY STAR Version 3 (V3), the 2012 International Energy Conservation Code, the U.S. Department of Energy's Zero Energy Ready Home Program, many state weatherization programs, and many other home performance programs. The standard calls for ventilation levels that are perceived by some builders and contractors to cause indoor moisture issues in hot-humid climates unless mitigated by supplemental dehumidification systems, which increase overall energy consumption. Therefore, many high-performance home builders in a hot-humid …
