Mandatory green roof?

Alas not in Asia. The green building is still driving built environment innovation, and whilst politicians ponder carbon limits, and building owners ignore operating costs then obviously the next step is regulation. In Canada, the Mayor of the Toronto is poised to implement legislation becoming the first city in North America to impose mandatory green roofing for an area of 5000 square metre and up. In my view It is yet another step in the right direction.

Its not Morse code
Essentially it all boils down to one issue, communication. From within the industry it is clear to see, look at any project brief, it includes those immortal words familiar to every developer, architect, and engineer on the planet “comply with code” or some equally ignominious phrase. This mini brief communicates to all parties the expected standard, covering all aspects of the building including occupancy, building safety, means of escape, fire prevention and protection, mechanical ventilation, etc. Its often used by those who don’t understand the individual legislative requirements, but know a building must comply with the local code to earn the necessary occupancy certificate.

Regulation
The implications are clear, green building is becoming main stream period. Once considered a fringe activity, at the edge of society, the development of green building has slowly entered the lexicon of typical both builders, developers, and regulators.

I don’t see this as a trend as many claim, flares were a trend, green building is not. However, just like consumers goods, some people will want to buy the latest camera/TV/computer/etc. and these early adopters are the real beneficiaries, because over time achieving a new green standard will only become increasingly difficult as the entry level bar is continuously raised.
