Green Roof of the Year 2014 30 Years and Counting

The second oldest Green Roof Association* in the world, FBB (Fachvereinigung fr Bauwerksbegrnung), awarded a prize for Green Roof of the Year 2014 to a 30 year old Green Roof on the Allianz Insurance Company in Stuttgart, Germany. Oldest Green Roof Association DDV (Deutscher Dachgrtner Verband).

The roof is one of the first projects where Jrg Breuning, CEO at Green Roof Service LLC / Green Roof Technology was substantially involved in the realization. Allianz Insurance Company decided in 1981 to build their local headquarters in the heart of Stuttgart. At that time the office building was already a big step forward for urban development in many regards. Along with very advanced, environmentally friendly technologies it was also one of the first buildings to achieve the split between living green working space and luxurious living in downtown of a large City.

The Green Roof is generally assembled around the building and on different levels. Most people in the offices have a view into the green spaces. Some areas of the Green Roof are accessible for coffee breaks and, on the highest floors there is usable garden space for the Condominium owners. The top floor even offers extensive lawn areas as playgrounds for kids.

All Green Roofs together measure over 21,000 sf. This inner city oasis utilized an advanced Optigreen Green Roof Systems with fully automatic high tide and low tide irrigation system in the mineral drainage layer. The plants decide when they need irrigation; no drop of water is wasted or can evaporate before reaching a plant. Neither a person nor electricity is needed to operate this fully mechanical system and it leaves enough room for precipitation to fill up the water storage under the plants. This green roof represents a smart combination of Blue Roof and Green Roof as Green Roof Service LLC / Green Roof Technology is still doing it on projects today. It is a foremost and 100% accurate irrigation system far beyond most irrigation systems that are operated by sensors, electricity, Apps, tubes, pipes or other highly vulnerable and expensive equipment we see every day on projects in North America or around the world.

The entire depth of this highly efficient Green Roof technology is approximately 18 inch and has allowed lawn, perennials, shrubs and small trees to grow for over 30 year without replacement or changing out the growing media.

Green Roof Service LLC / Green Roof Technology is proud of this Award and we are pleased to offer more information about it. We offer Green Roof tours for anyone interested in this kind of technology.

This has been a landmark project for more than 3 decades and we congratulate all who are part of this Award!

Uneven Water Supply for West

Green Team at Green Roof Technology, — Tuesday, July 15, 2014

WASHINGTON . June 18, 2014 — The final water supply forecast for this year shows the West divided into a wet north and dry south while snowpack has already melted in much of the region, according to data from the USDA National Water and Climate Center (NWCC).

Washington, most of Idaho, Montana, Wyoming and the northern parts of Colorado and Utah are expected to have near normal or above normal water supplies through the rest of summer, according to the forecasts. Far below normal streamflows are expected for the southern parts of Oregon and Utah, southwestern Idaho, California, Arizona, New Mexico and western Nevada.

Many of these areas are in the nearly 500 counties across the country experiencing drought, 57 of them in California alone, according to USDA disaster designations .

This year saw near-record low snowfall in parts of Nevada, California, Arizona, New Mexico and the southern parts of Utah and Oregon. Even with some May precipitation, those areas remain dry. The biggest change this season was in the Washington Cascades. At the beginning of February the snowpack was about half of normal, but it recovered and most of Washington will have a near normal water supply from snowmelt, according to the Center.

Spring snowmelt is well underway, according to NWCC hydrologist Cara McCarthy. A lot of our SNOTEL sites have already melted out, especially those in the southern half of the West, McCarthy said.

Colorado had mixed weather during May. They had winter and summer all in one month: snowmelt, snowfall, snowmelt, said McCarthy. Heavy precipitation combined with snowmelt, causing flooding in parts of the state.

Forecasters monitor conditions all year, but June is the final forecast of the season. These are snow-based water supply forecasts, McCarthy said. Typically by July there won’t be enough snow left on the ground (to measure).

In Western states where snowmelt accounts for the majority of seasonal water supply, information about snowpack serves as an indicator of future water availability. Streamflow in the West consists largely of accumulated mountain snow that melts and flows into streams as temperatures warm into spring and summer. USDA scientists analyze the snowpack. air temperature, soil moisture and other measurements taken from remote sites to develop the water supply forecasts.

The NWCC water supply forecast is part of several USDA efforts to improve public awareness and mitigate the impacts of climate change, including drought and other extreme weather events. Through the creation of the National Drought Resilience Partnership, launched as part of the Presidents Climate Action Plan. federal agencies are working closely with states, tribes and local government to develop a coordinated response to drought.

Since 1939, USDA has conducted snow surveys and issued regular water supply forecasts. View information by state .
