Domus Alba
“GAF roofing has proven to accomplish the qualities that were desired by
the architect/owner. A 60-mil fleece-back white TPO roofing membrane and
R-30 Icynene under-slab insulation complete the cool-roof construction,
which reflects around 87% of the sun’s damaging UV rays off the roof.”

Building Overview
• Domus Alba is the residential home of David M. Harper, principal and director
of the architectural firm HKS. Wanting to walk the walk about sustainability, he
decided to follow his own example to build and design a home that would
showcase the highest standards of sustainability, architecture, and energy
conservation. The home features six bedrooms, six bathrooms, two
half-bathrooms, a three-car garage, saltwater pool, jacuzzi, and much more.
Challenge
• The Harper family wanted to raise the bar and highlight their commitment to
sustainability by obtaining LEED® Gold Certification on their new home. However,
the size of the building made it challenging, since larger homes use more energy.
Plus, the house is located in a high-heat and humidity zone in Florida, which made
it harder to design the home to have low-energy use.
Materials Used
• Complete concrete shell
• EverGuard® Fleece-back TPO 60 mil
• R-30 Icynene under-slab insulation
Solution
• GAF roofing was chosen for its durability, quality performance, and safety benefits
toward LEED® accreditation and for the options available for environmentally
friendly solutions. Installing the TPO cool roof and high-efficiency insulation was
instrumental in helping the Harpers achieve their sustainability objectives.
Key Facts
• The roof and insulation combined with home automation, LED lighting, sunshades,
and other eco-friendly products helped the home achieve a High Energy Rating
System index rating of 33 (most newly built homes have a HERS rating of 100).
• The Harpers’ home also received the 2014 Most Outstanding LEED® for
Homes/Single Family Project by the U.S. Green Building Council of South Florida
and the 2015 AIA Miami Chapter Committee on the Environment (COTE) Award of
Merit for Sustainability.
