Cat Houses Go Green!

11 Sep

These sustainable pet houses are the design of Greenrrroof Animal Homes as seen on their website

A search on Wikipedia gives the following information on sustainable house design:

A green roof is a roof of a building that is partially or completely covered with vegetation and soil, or a growing medium, planted over a waterproofing membrane. This does not refer to roofs which are merely colored green, as with green roof shingles. It may also include additional layers such as a root barrier and drainage and irrigation systems. Container gardens on roofs, where plants are maintained in pots, are not generally considered to be true green roofs, although this is an area of debate. Rooftop ponds are another form of green roofs which are used to treat greywater. Finally, the term “green roof” may also be used to indicate roofs that utilize some form of “green” technology, such as solar panels.  Green roofs are also referred to as eco-roofs, vegetated roofs, living roofs, and greenroofs.

Green roofs are used to:

  • Grow fruits, vegetables, and flowers
  • Reduce eating (by adding mass and thermal resistance value) and cooling (by evaporatvie cooling) loads on a building — especially if it is glassed in so as to act as a terrarium and passive heat reservoir
  • Increase roof life span
  • Reduce storm water run off — see water-wise gardening
  • Filter pollutants and CO2 out of the air — see living wall
  • The soil and plants on green roofs help to insulate a building for sound; the soil helps to block lower frequencies and the plants block higher frequencies.[2]
  • Filter pollutants and heavy metals out of rainwater
  • Increase wildlife habitat in built-up areas — see urban wilderness

A green roof is often a key component of an autonomous building.

A 2005 study by Brad Bass of the University of Toronto showed that green roofs can also reduce heat loss and energy consumption in winter conditions.

In a recent study on the impacts of green infrastructure and in particular green roofs in the Greater Manchester area, researchers found that adding green roofs will help keep temperatures down, particularly in urban areas: “adding green roofs to all buildings can have a dramatic effect on maximum surface temperatures, keeping temperatures below the 1961-1990 current form case for all time periods and emissions scenarios. Roof greening makes the biggest difference…where the building proportion is high and the evaporative fraction is low. Thus, the largest difference was made in the town centers.
