Remove all existing attic insulation in the main body of the home; there is R-30 fiberglass batt insulation in the
family room addition. Cellulose insulation will be added to the existing fiberglass batt insulation to achieve a
total R-value of R-60,
Remove all existing HVAC equipment in the interior closet of the home,
Remove all existing ducting in the attic,
Remove the existing tank style water heater in an interior closet,
Remove three wall mounted air conditioning units, one located in bedroom #2, one in the kitchen nook area and
the one in the family room,
Remove an existing “pellet” style fireplace from the family room,
Close off and frame in an existing wood burning fireplace located in the family room,
Install a new “right sized” HVAC equipment in the attic. Equipment is as follows: Goodman gas furnace 95%
with a Goodman condenser 16 SEER-13 EER with an ARHI # of 3669754,
Install all new software designed R-8 flex ducting system in the attic including Shoemaker low static pressure
register grilles,
Air seal the complete building envelope with a focus on the attic to interior space plane,
Install a Noritz model number NRC98 tankless water heater in the attic with an efficiency factor of 93%,
Install new windows throughout. Windows are vinyl frame, dual glazed, Low-E² glazing with the following
values, U=.34, SHGC=.29,
Install Panasonic “continuous rated” bathroom exhaust fans in the master and hall bathrooms.
Install polyurethane closed cell foam on all the crawlspace subfloor to a minimum of R-19.
Install loose fill cellulose insulation in the attic area to achieve a total R-value of R-60.
Install high efficacy LED interior and exterior lighting.
Install an energy-efficient Pentair pool pump.
Install a 5.2 KW roof mounted Solar PV system.
Final Results of Taurus Court “Deep Energy Retrofit”:
Taurus Ct. is a 2,200 S.F. home built in 1958. The average monthly PG&E Gas bill “prior” to the retrofit averaged $75 and
the SMUD Electric bill averaged $300. The “combined” PG&E and SMUD bills “post” retrofit has been reduced by about
$340. This represents a combined monthly savings exceeding 85% allowing an extra $340 per month to be "re- directed”
to the family budget and the local economy. This is an effective way to turn your home into a “positive cash flow”!
The process utilized to complete the Taurus Court project was modeled from the success achieved in Fresno California
by Green Earth Equities (GEE) who have delivered the highest level of residential energy-efficiency in the country
resulting in two contracts with the U.S. Department of Energy (DOE).
The “Community Home Energy Retrofit Program” (CHERP) will feature Taurus Court as a “Case-Study”:
CHERP is the most successful public awareness and consumer educational program in the country teaching homeowners
how to “maximize” home energy-efficiency and to “minimize” the overall cost of improvements. Jack Frost, President of
Green Earth Equities/ Sacramento has been appointed as the Sacramento Regional CHERP Director. Jack is planning to
use his home on Taurus Court as a “Case-Study” to help homeowners learn about the wide range of energy-efficient
upgrades available to improve the health and comfort of their homes and to learn how they can significantly reduce their
utility bills. Jack has a letter of interest from the U.S. Department of Energy (DOE) for a “Net-Zero” Demonstration Project
in the Greater Sacramento Region to help CHERP further expand public awareness and consumer education.
