Cost Modelling for Energy Efficient Window Replacements
This paper detailed data collection and cost-modeling efforts to understand the hardware and non-hardware (soft) cost of residential, energy efficient window replacements. NREL created a bottom-up cost model that details costs associated with window materials, installation labor, company overhead, and administrative costs. NREL did not find a single cost area for improvement but observed several non-cost barriers to increased window replacements. The non-cost barriers associated with window replacements are consumer education, lack of communication of the value of window replacement to consumers, and difficulty for consumers to identify quality products and installation.
