Please note:
These calculations are hypothetical estimates only. They are based
upon a number of factors, including your computer input, average
heating/cooling energy consumption in 256 cities around the United
States and Canada, average fuel costs in various regions of the
United States and Canada, laboratory controlled air infiltration
measurements and reasonable assumptions of average heat loss or
gain attributable to air infiltration controllable by DuPont Tyvek®
Weatherization System Products in an average home. Because factors
affecting energy savings are so variable, these hypothetical calculations
are made solely for the purpose of demonstrating that DuPont Tyvek®
Weatherization System Products, if properly installed, can provide
meaningful energy savings.
These calculations
are not meant to be nor should they be used as actual or expected
energy savings claims for housing using DuPont Tyvek® Weatherization
System Products. Numerous variables including living habits of
occupants, fuel costs, house construction and location, weather
conditions, etc. can significantly affect energy savings attributable
to such products.
The closest city to
the zip code provided for which long-term weather data is available
and upon which calculations were performed is PHILADELPHIA.
