Resource Efficient
Building · Louisville, KY
This 5,400 square foot guest
house is an example of energy efficiency and ecologically
sound materials. Views to the south east and
south west demanded large glass areas. Solar gain
was controlled by using infrared rejecting low-e
glazing.
The house will be used for guests,
has apartments for a nanny and grounds keeper,
and as a workshop for the owner's home occupation
as an inventor of high tech machinery.
Resource and energy efficient
materials include R-8 windows, recycled cellulose
insulation R-44 at roof and R-30 at walls. High
efficiency HVAC equipment is zoned and has intelligent
controls. When weather permits the house is cooled
with natural ventilation augmented with a whole
house fan. Hot weather cooling is made more efficient
with ground water cooled heat pump. Natural gas
provides heating. Domestic hot water is provided
with natural gas high efficiency condensing type
water heater. A blower door test for air infiltration
provided quality control. Siding and soffits are
industrial quality cement fiber boards applied
with stainless steel screws that will be left
unpainted and have a life span of 65 years minimum.
Recycled plastic lumber is used for exterior trim
and deck boards.
