    Green roof policy

    Hi Everyone,

    I'm a Masters of Planning student at the University of Auckland, New Zealand. This year I'm writing a thesis on green (or eco) roofs and how policy can be created to provide incentives for developers to install these on new commercial buildings. I would like to hear from anyone involved in, or who knows someone involved in, the area of green roofss. I'm particulary interested in those who something to do with the policy side of things.

    Anyone who wants to discuss green roofs and there benefit to the wider urban environment is also more than welcome to post a reply.

    Cheers

    Logan

    No. Just some parts wake up faster than others.
    Broke parts take a little longer, though.

    Many cities offer reductions in plan review fees, impact fees, etc. for this type of thing. They also will frequently adjust landscaping requirements and such.

    "Oh, that is all well and good, but, voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same way in any country."

    Last year the state of NJ instituted new stormwater regulations requiring higher rates of removal of TSS (Total Suspended Solids), reduction of off site runoff, improved infiltration rates etc. One of the things they encourage is using green roofs to hold onto rainwater.

    There are several people in the US that I can think of who are actively involved in encouraging policy to support green roofs, but I don't know that they've had much of a hand in actually writing policy.

    Corporations are finding it makes good sense to be leaders in this. Ford Motor has a green-roofed facility where is makes its F-150 truck. The roof is well over ten acres. I've toured it and it is phenomenal. The $2 billion facility uses runoff to flush toilets, has its own bees and orchard to pollanate (sp, I'm no biologist) the roof, and uses natural light wherever possible. Here is a link to an article about it.

    In addition, SEMCO, a natural gas company, is building a new headquarters in Downtown Port Huron. This building will also be a green building, and be well integrated into this town's historic fabric; bringing hundreds of needed jobs to the Downtown.

    For the British version, try: http://www.livingroofs.org/
    And using http://www.google.co.uk with "green roofs" comes up with loads of stuff.

    I don't know much about the policy side of it, but I have to say I do like the idea. It appeals to the environmentalist, the conservationist, the engineer and the sci-fi geek in me

    Boy, I'd love to be able to pull that off in my community. I'll be checking back on this thread for sure!
    You only need two tools: WD-40 and Duct Tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

    I imagine green roofs can be a huge improvement in New Zealand, as they have been very successful in Germany. As long as the policy fits the environment, great. But, if an incentive is available to those who cannot effectively use it (arid climates, perhaps), it may be perceived as unfair.

    An Austin, Texas-based architect who lectured on the U.S. Green Building Council's LEED program claimed that green roofing systems are not effective in our climate. We get relatively low rainfall (~30 inches/year), but it comes in sudden rainstorms followed by blazing heat 3 seasons out of the year.

    In America, such a policy could be brilliant in the Pacific Northwest or Northeast Atlantic coast, but may not be implementable in most of the nation.

    Thanks for all the great posts people, keep them coming. Every bit of information helps as sometimes it can be hard accessing all the information that I need due to distance between New Zealand and North America.

    The climate in New Zealand, or at least Auckland where I am, is similar to that of the Pacific North West. We get quite a high amount of rainfall during the winter / spring months and our temeperatures seem to be quite comparable. Therefore, I think that many of the benefits associated with green roofs in Portland, for example, could be seen if green roofs were constructed in Auckland.

    One of the main barriers to green roof development here is that there are no working examples other than small scale roofs on co-op style housing. These roofs have not been designed or installed by green roof specialists so developers do not take these examples seriously. As there are no green roofs built we do not have any accreditation scheme to ensure that these roofs will not leak leading to a lack of confidence in this technology in NZ.

    Any ideas on how the green roof message could be spread in NZ? Examples could include information workshops for govt. agencies or possibly setting up a demonstration model to show the technology working.

    Try contacting the City of Vancouver, BC,Canada - they are currently investigating have green roof incentives for all new building construction in the City. Given that the climatic conditions are pretty similar, you should look at their website for more info.

    Green Roofs are becoming more and more is use over here, mainly for the purposes of water retention and attenuation. There's quite a few springing up, particularly in Scotland, which is always at the vanguard of SUDS (Sustainable Urban Drainage Systems) policy and use over here.

    Maybe because they get more rain than England, or maybe because their national Environmental Protection agency (SEPA) seem to be better organised than the English and Welsh one (EA) - I don't know

    It's not the same thing, but an option to a green roof is to capture rainwater from the roof using rainwater harvesting methods. The water can then be piped into separate systems for irrigation or plumbing in toilets/urinals--anywhere you don't need potable water. Something you might throw into the mix.
