Currently slated for construction in Singapore, the EDITT Tower will be a paragon of “Ecological Design In The Tropics”. Designed by TR Hamzah & Yeang and sponsored by the National University of Singapore, the 26-story high-rise will boast photovoltaic panels, natural ventilation, and a biogas generation plant all wrapped within an insulating living wall that covers half of its surface area.

Green Roof Moss

Green Roof Moss

Mosses have been used for years in Europe for green roof applications. The shade loving mosses available from Moss Acres are now being specified and used on several green roof projects in the U.S. at shady locations where conventional green roof plants are less ideal.

In a green roof application it appears that moss requires an inch or less of medium and can tolerate extensive periods of lack of rainfall once established. Provided it is located in a shaded or partially shaded roof location, moss can contribute to creating a truly bio-diverse green roof.

Moss is also lightweight and can dry out for weeks on end, only to absorb significant amounts of water and return to it's lush appearance soon after a rain event - the perfect traits for any green roof plant.

Mosses can add uniquely appealing colors and textures to green roof projects, and because Moss Acres ships three of its four varieties of mosses boxed dry, moss can be incredibly easy and cost-effective to install on green roof projects.

Upon attending a wedding recently, owner of Moss Acres, Al Benner looked up and snapped this photo. It shows a conventional asphalt shingled roof covered with naturally occuring Haircap and Fern moss, right beneath the shade of an oak tree. Beautiful, cooling, and water absorbing - nature has it figured out all by itself!

Dug into hillside for low visual impact and shelter
Stone and mud from diggings used for retaining walls, foundations etc.
Frame of oak thinnings (spare wood) from surrounding woodland
Reciprocal roof rafters are structurally and aesthaetically fantastic and very easy to do
Straw bales in floor, walls and roof for super-insulation and easy building
Plastic sheet and mud/turf roof for low impact and ease
Lime plaster on walls is breathable and low energy to manufacture (compared to cement)
Reclaimed (scrap) wood for floors and fittings
Anything you could possibly want is in a rubbish pile somewhere (windows, burner, plumbing, wiring...)
Woodburner for heating - renewable and locally plentiful
Flue goes through big stone/plaster lump to retain and slowly release heat
Fridge is cooled by air coming underground through foundations
Skylight in roof lets in natural feeling light
Solar panels for lighting, music and computing
Water by gravity from nearby spring
Compost toilet
Roof water collects in pond for garden etc.

"rooflite™ is a precisely engineered growing media specifically for green roof applications. rooflite™ is manufactured to meet all related current and future ASTM standards as well as the German FLL-Greenroof Guidelines. The history of modern green roof technology started 30 years ago in Germany. The German FFL- Greenroof Guidelines (ForschungsgesellschaftLandschaftsentwicklung Landschaftsbau e.V., Guideline for the Planning, Execution and Upkeep of Green Roof Sites, Release 2002) reflect the latest developments and worldwide acknowledged state-of-the-art technology. These German Green Roof Standards are universally accepted as the scientific foundation for successful and thriving green roofs worldwide."

Green Rooftops Made Fast, Smart and Economical with Concrete

Posted by starstuff on 2008/11/3 17:20:47

Using Hydrophobic Pore-Blocking Ingredients (HPI's), waterproof concrete systems have proven themselves to be fast, smart and economical systems that can boost the greenroof industry.

These systems are fast because waterproofing is done right at the time of concrete placement, with no extra steps. They are smart because the technology is backed by a proven track record of over forty years and is not vulnerable to damage, reducing the liability of all parties. HPI’s actually reverse the normal absorptive nature of hardened concrete, making it physically water-repelling and non-absorptive so it won’t transmit moisture, dampness, or the salts and acids that the moisture may contain.

These systems are economical because of the initial cost/construction savings, as well as the significant long-term savings. Both bring down the cost of owning a structure with a green roof.

When truly waterproof concrete is specified for a green roof application, the owners know that they have a system which will not wear out or ever need replacement. They also know that if problems occur, there is a very simple identification and repair process that eliminates any need to disturb the growing medium.

Hydrotech's Garden Roof® Assembly allows the design professional to transform virtually any flat or sloped roof into a landscaped environment. Designed as a lightweight, low profile system, the Garden Roof Assembly can be safely installed on roof and plaza decks not engineered to handle the heavy load requirements of a traditional green roof. And because the assembly incorporates Hydrotech's Monolithic Membrane 6125®, a proven roofing/waterproofing membrane, the building owner can be assured of a water-tight structure. - more
