Notas del editor
- *Based on past 5 yr building permit data (US Census)
- Mobile Homes begin to get national attention for their poor air quality and construction materials
- 438 mobile homeowners were eligible for FEMA assistance 129 mobile homes required complete demolition or removal
- High Interest Rates (More than 7.5%) Short Term Mortgages (Less than 20 Years) High Energy Costs (More than $350 in energy costs)
- Almost 75% of Vermonters that live in mobile home parks are under 80% median income
- Air quality management is the CERV’s top priority. When indoor levels are below setpoint, but your heating or cooling is not satisfied, the CERV will enter a recirculation mode. Recirculation mode is important for efficiency because it utilizes the fresh air stored in the unoccupied regions of your home which helps maintain uniform comfort The CERV automatically acts to exchange energy and moisture at an efficiency that can be greater than 100%. The CERV’s heat pump can extract energy and moisture
- The higher the R-value, the better the insulation material's ability to resist the flow of heat through it. Floor R-40 Walls R-43 Roof R-60
