Albuquerque, New Mexico
Typical Year (TMY3) HDD65 4157 / CDD65 1269, Hot Year (2001) HDD65 3940 / CDD65 1535
Tables 249-252 show the impact of awnings
on a typical house in Albuquerque with
different window orientations over a typical
year. Tables 253-256 repeat this analysis for
a hot year in Albuquerque. The impact
varies depending on the type of window
glazing and whether the awnings are in
place all twelve months or only during the
cooling season. For a house with windows
equally distributed in the four orientations,
Table 249 shows the annual heating and
cooling energy use as well as the peak
electricity demand for each combination of
glazing and shading condition. The table
also shows the impact on the total cost for
heating and cooling. In all cases, the net and
percent savings are in reference to a house
with no shading.
Table 249 shows that awnings reduce
cooling energy use by 26-39 percent as
compared to the unshaded house. The
higher savings are for awnings at 165
degrees over windows with clear
glazings, while the lower savings are for
awnings at 90 degrees over windows with
Low-E glazings. Because awnings block
useful solar gain in winter, heating energy
use increases when the awnings remain in
place 12 months a year. Using the
awnings only during the cooling season
produces the largest net energy savings.
The net energy savings are from 4 to 6
percent in Albuquerque when awnings are
used only during the cooling season from
April through October, while the penalties
are from -16 to -9 percent when they are
deployed throughout the year.
Table 249 also shows that awnings reduce
peak electricity demand by 10-15 percent
in Albuquerque, with larger reductions for
the clear glazings and smaller reductions
for the Low-E glazing. Tables 250, 251,
and 252 show results for houses in
Albuquerque where the windows
predominantly face to the east, south, and
west, respectively. Both the cooling
energy savings and the peak demand
reductions are largest on west-facing
awnings. Tables 253-256 show the
impact of awnings on a particularly hot
year (2001) in Albuquerque. The main
effect is to increase the cooling savings by
61 percent due to the hotter or longer
summer.

The costs shown here are annual costs for heating and cooling only and thus will
be less than the total utility bill. Heating is assumed to be provided by a gas
furnace and cooling by a central air-conditioner. Electricity costs used in the
analysis are 8.4 cents per kWh and natural gas costs are $12.64 per MBTU,
which are the average costs in 2009 for the state of New Mexico according to the
Energy Information Administration (see Appendix E for details).
