||Miniature Golf on the Roof at Lunchtime a Possibility with Green
Green roofs positively impact environments. In cities, they introduce
vegetation and birds while absorbing heat and water. They transform
concrete, asphalt, and pipe rooftops into green respites of sanctuary
ASTM Subcommittee E06.71 on Sustainability has worked to improve
eco-systems since 1998. Its sustainable-building standards recommend
energy efficiency through smarter building design and choice of
materials. By promoting greener buildings, the subcommittee attempts
to improve environmental systems locally and globally.
Subcommittee E06.71 approved a Green Roof Task Group in October,
during meetings of ASTM Committee E06 on Performance of Buildings in Dallas. Horticulturists, architects,
manufacturers of green-roof systems, roofing specialists, corporate
stakeholders, and scientists from Michigan, Rice, and Penn State
universities are among those who joined the new task group.
Standards they develop will cover guidance for green roof design
and construction. Basically the concept is to create something
on the roof that is living, that is vegetation of some kind,
said the task group chairman, Michael F. Gibbons, FCSI, Architectural
Systems, Inc., Dallas, Texas. It doesnt have to be a garden;
it doesnt have to just be grass. It can be a combination of things.
Gibbons said green-roof landscaping can provide a putting green
for golfers, a rest area for hospital patients, or a break area
for business professionals.
The concept is to create an inhabitable space with life on it.
It could be a golf course, a garden, or landscaping, he explained.
Or it could just be grass or wild sedum and moss.
Green roofs support aesthetically pleasing plant life typically
installed on flat or sloped roofs. As well as plant life, components
of a green roof usually include a waterproofing membrane, vapor
barrier or retarder, thermal insulation, flashings and a system
to both retain water and facilitate drainage.
Standards developed by the task group may cover roofing and waterproofing
materials, plant growth, soil, drainage, and energy efficiency.
