Equipment sizing. The higher-performance window replacement options would allow reduced sizing of the residential unit heat pumps, as the heat pumps are eventually replaced. The highest-performance replacement option is estimated to reduce peak heating loads 33%-47%, and peak cooling loads 19%-33%. This would allow a replacement heat pump sized at least one step smaller ameristep than the existing pump in pretty much every residential unit, yielding reduced replacement cost, reduced replacement peak loads on the utility, reduced windows operational noise level, and possibly better dehumidification performance during the cooling season.There would be little or no equipment sizing benefit associated with the clear glass window replacement options, however. This is because the clear glass options produce only small ameristep peak cooling load reductions and peak heating and peak cooling are roughly equal in these buildings. In a colder climate, where heating loads are dominant, the clear glass options would replacement also allow equipment size reduction in many cases. It''s clear that energy savings alone won''t justify window replacement (see "Other Considerations in Window Replacement"). If windows are to be replaced in any case, windows however, the analysis provides justification for an upgrade to high-performance glass. At a cost of $60 per window, the payback on low-e argon filled glass is a reasonable 9 years.And there are other issues to be considered. The companion study ameristep on window replacement condition estimated the current value of deferred maintenance at over $1 million, which reduces the comparative windows cost of window replacement. Comfort and other ameristep effects may be difficult to quantify in dollar replacement terms, but they have important costs and benefits.
