Green Roof Innovation Testing Laboratory

Last updated

The Green Roof Innovation Testing Lab ("GRIT Lab") is a University of Toronto research facility at the John H. Daniels Faculty for Architecture, Landscape and Design. [1] The only facility of its kind in Canada, [2] the GRIT Lab tests and researches the environmental performance of green roofs, green walls, and solar photovoltaic technologies in Canada to help mitigate climate change. [3]

Contents

The GRIT Lab is run by a team of landscape architects, civil engineers, building scientists, and biologists from the UofT Daniels Faculty, including Director Liat Margolis as well as professors Robert Wright, Dr. Ted Kesik, Dr. Brent Sleep and Jennifer Drake. [4] [5]

Related industry partners such as Tremco, Bioroof Systems, and Sky Solar, as well as government agencies including the City of Toronto, and other academic institutions are also involved in the project. [6]

History

The GRIT Lab was established in 2010 on the roof of the Daniels Faculty at 230 College Street in Toronto by the Daniels Faculty’s Centre for Landscape Research. [7] The opening of the lab came after the City of Toronto introduced a by-law in May 2009 that required all new developments in the city larger than 2,000 square meters to incorporate a certain percentage of green roof space. [6] [8]

Operations began in 2011 to monitor the performance of the city’s recommendations. [3] This is done by testing the effectiveness of various green roofs, green walls, and solar photovoltaic technologies in the Toronto climate. [3] [7] The experiments aim to reveal the optimal construction of green roofs and how to maximize environmental performance. [9]

In addition to testing, the lab also offers private educational seminars to related organizations and those interested in green-thinking. [6]

To date, the GRIT Lab consists of 48 boxed plant testing beds, a variety of green walls, and its own weather station. [1] Data is regularly collected on soil moisture, flow rates, temperature, rainfall, humidity, solar, and wind to determine which combinations can produce the greatest cooling and stormwater benefit. [5] [1]

In 2013, a website was established to share the results of the lab’s research with the public. [7]

In 2017, the lab moved from College Street to the fifth floor roof of the Daniels Faculty’s new home at 1 Spadina Crescent. [1] The new lab at 1 Spadina focuses on both testing the absorptive qualities of green roofs, as well as the effectiveness of cisterns or holding tanks at keeping rainwater out of storm sewers and the ground. [6]

Awards

In 2013 the GRIT Lab received an Award of Excellence from the American Society of Landscape Architects. [10]

Green roof

A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. 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 debated. Rooftop ponds are another form of green roofs which are used to treat greywater. Vegetation, soil, drainage layer, roof barrier and irrigation system constitute green roof.

National Renewable Energy Laboratory United States national laboratory

The National Renewable Energy Laboratory (NREL), located in Golden, Colorado, specializes in renewable energy and energy efficiency research and development. NREL is a government-owned, contractor-operated facility, and is funded through the United States Department of Energy. This arrangement allows a private entity to operate the lab on behalf of the federal government. NREL receives funding from Congress to be applied toward research and development projects. NREL also performs research on photovoltaics (PV) under the National Center for Photovoltaics. NREL has a number of PV research capabilities including research and development, testing, and deployment. NREL's campus houses several facilities dedicated to PV research.

1 Spadina Crescent

1 Spadina Crescent, also known as the Daniels Building, is an academic building home to the John H. Daniels Faculty of Architecture, Landscape, and Design at the University of Toronto in Toronto, Ontario, Canada. The building is situated in the centre of a roundabout of Spadina Avenue, north of College Street. Its location provides a picturesque vista looking north up Spadina Avenue; it is an axial view terminus for Spadina Avenue.

In the 19th century, it was observed that the sunlight striking certain materials generates detectable electric current - the photoelectric effect. This discovery has laid the foundation of solar cells. Solar cells have gone on to be used in many applications. They have historically been used in situations where electrical power from the grid was unavailable.

Solar panel

The term solar panel is used colloquially for a photo-voltaic (PV) module.

Zero-energy building Energy efficiency standard for buildings

A zero-energy building (ZE), also known as a zero net energy (ZNE) building, net-zero energy building (NZEB), net zero building is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site, or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows and insulation, and solar panels. The goal is that these buildings contribute less overall greenhouse gas to the atmosphere during operations than similar non-ZNE buildings. They do at times consume non-renewable energy and produce greenhouse gases, but at other times reduce energy consumption and greenhouse gas production elsewhere by the same amount. Zero-energy buildings are not only driven by a want to have less of an impact on the environment, but theyare also driven by money. Tax breaks as well as savings on energy costs make Zero-energy buildings financially viable. A similar concept approved and implemented by the European Union and other agreeing countries is nearly Zero Energy Building (nZEB), with the goal of having all buildings in the region under nZEB standards by 2020. Terminology tends to vary between countries and agencies; the IEA and European Union most commonly use "net zero", with "zero net" mainly used in the USA.

Building-integrated photovoltaics Photovoltaic materials used to replace conventional building materials

Building-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, or facades. They are increasingly being incorporated into the construction of new buildings as a principal or ancillary source of electrical power, although existing buildings may be retrofitted with similar technology. The advantage of integrated photovoltaics over more common non-integrated systems is that the initial cost can be offset by reducing the amount spent on building materials and labor that would normally be used to construct the part of the building that the BIPV modules replace. These advantages make BIPV one of the fastest growing segments of the photovoltaic industry.
