From rooftop gardens to big box stores in North America, green roofs are a hot item in sustainable design. They promise better views for neighbouring buildings, diminish the heat island effect, and contribute to water conservation measures.
Green roofs have been in use since the Middle Ages in Europe, and sod roofs were a feature of pioneer homes in North America. After the oil crisis of the early 1970’s, Germany experimented with roof landscaping for energy conservation purposes. That country boasts more than 13 million square metres of green roofs.
With green roofs proliferating in sustainable design circles, standards for their design and construction have been established and field tested. The British Columbia Institute of Technology (BCIT) has developed a Centre for the Advancement of Green Roof Technology with a focus on developing green roof and living wall technologies for the BC coastal region. Lessons learned here are being applied in other jurisdictions.
What is a Green Roof?
BCIT defines green roofs as engineered roofing systems incorporating the use of vegetation that make environmental, economic and social contributions to urban areas. It distinguishes between three kinds of green roof:
- Extensive green roofs, ideal for large flat-roof buildings and apartments and requiring little maintenance after being established
- Intensive green roofs, or rooftop gardens requiring regular maintenance much like an at-grade garden
- Semi-intensive green roofs which combine aspects of both of the above roofs

The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More
Stinging Nettle
In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More
