Your Roof: Once Black, Now Green – Meakin Armstrong – National – The Atlantic   1 comment



Toronto has been aggressive about it: they have a new, comprehensive green roof law, the first one in North America.

Like all laws, it’s complicated, but new building permit applications for residential, commercial, and institutional developments must now have green roofs. New industrial developments (as of April 30, 2012) will soon have to be green, also.

The law states a minimum roof size, so it doesn’t apply to gardening sheds. And the larger the roof, the greater the percentage of it will have to be green. People can opt out, but they have to pay toward a fund.

Efforts are already paying off: Green Roofs for Healthy Cities is reporting that the law has resulted in more than 1.2 million square feet of new green space planned on new commercial, institutional, and multi-unit residential developments. It will also keep enough rainwater runoff out of the lakes and rivers to fill fifty Olympic sized swimming pools. It’s reduced the heat island effect and led to an annual energy savings of over 1.5 million KWH for building owners.

And there are still other benefits: opportunities for parks and recreational areas. Birds and bees do well with these changes. To get an idea of what these roofs can look like, here’s a collection of still images of green roofs around the world.

Other cities are trying to catch up with Toronto. New York City is in the midst of its PlaNYC initiative that’s encouraging green roofs, planting trees, and trying to improve the streetscape so to minimize the heat island effect for which the city is notorious: temperatures there can exceed rural areas by seven degrees. The first green roof in New York City, which is at a large post office facility in Midtown, saves its owners $30,000 in electrical bills.

What’s stopping people the world-over from having green roofs? Higher initial cost. Sometimes, higher maintenance cost or roofs unable to handle the weight. But proponents say electrical savings can help in those areas. Also because the roof is covered with waterproofing and a lot of dirt, the roof is preserved and tends to last longer. And more buildings are under construction that have been designed with green roofs in mind, like this refinery office in Rotterdam.

What’s next? Perhaps “blue roofs,” which preserve rainwater for recreation, like at Urbeach. Then, there’s this: what about green floors? Or Depave, a Portland group that rids areas of “unnecessary concrete?” ”

New Move to Develop Global Standards for Measuring Energy Use in Buildings – UNEP   Leave a comment

The UNEP Common Carbon Metric  is a most welcome effort in the measurement  of  building-related CO₂ emissions .

“Efforts to establish international standards for measuring energy use in buildings have received a boost, after the International Organization for Standardization (ISO) decided to consider an innovative tool developed by the United Nations Environment Programme (UNEP) to gauge energy consumption and CO₂ emissions in homes and offices across the world.

The Common Carbon Metric (CCM) – developed by UNEP’s Sustainable Buildings and Climate Initiative – could form the basis for a new international standard for measuring the environmental performance of existing buildings. The ISO – the world’s largest developer and publisher of international standards, covering 162 countries – will develop relevant methods.

The Common Carbon Metric is intended to create a uniform system for defining the climate impact of buildings through a consistent protocol, which can, in turn, help develop international baselines for use by architects, designers and the construction industry.

Today, the building sector is the single largest contributor to greenhouse gas emissions with about one third of global energy use taking place in offices and homes. Moreover, building-related CO₂ emissions are set to rise from 8.6 billion tones in 2004 to 11.1 billion tones in 2020.”

Top Ten Highlights of the League of Green Embassies | CleanTechies Blog –   Leave a comment

“The League of Green Embassies was created by the United States Department of State. It was established as an initiative to promote international cooperation for clean technologies and energy efficiency. There are three major objectives of the League of Green Embassies are, “To advance the Presidential mandate to reduce greenhouse gas emissions in USG buildings; to demonstrate the capabilities of U.S. products and technologies to the world market; and to increase the exports of U.S. products and services in line with the national Export Initiative.” When the league was established in 2007, it was run by former U.S Ambassador to Sweden, Michael M. Wood. In 2010, the U.S. Embassy in Helskini’s ambassador, Bruce J. Orek, took over the league.”

Although this is USA centric , all nations can take note and focus on the methods and merits of greeen building… nad principles of sustainability.
