The green plot ratio, known as GPR, is a powerful metric in urban design and development.
GPR is an architectural metric utilized for assessing and planning the inclusion of greenery in cities and buildings. This metric was devised by Singaporean landscape architect Dr. On Boon. GPR was developed with the intent of optimizing the amount of green space, or plant coverage, in an urban environment.
Using GPR an architect has a quantifiable measure to determine how much greenery should be incorporated to counteract the absorption of heat in the building fabric as well as enhancing the qualities of open space.
GPR is a scientific ratio of plant coverage onsite to determine the ideal amount of greenery for creating sustainability in urban design. The ratio is determined based on the biological parameter of the "leaf area index", or LAI, a form of measurement for the total leaf area per unit of ground area. LAI is calculated by taking a sample of foliage from the plant canopy, measuring the leaf area of the sample, and dividing it by the relevant plot size. The resulting GPR is the average LAI of the greenery on site, and the ratio depends on the type of greenery:
Urban green space helps play a vital role in the sustainable design and biodiversity within cities. Quality urban green space can help improve the quality of city life. Architects can utilize GPR to help maximize your green space potential without sacrificing on the utility or overall vision of the building project.
Urban sprawl has led to increases in pollution, consumption of energy and resources. As a response to the global climate crisis, increasing the use of greenery in our architectural designs can help drive sustainable development.
The increased use of plants in urban design drives health and well being benefits, affects the quality of the air in our city and can contribute towards decreasing the effect of heat islands.
If you’d like to know more about implementing GPR on an upcoming project, contact Scott Henson Architect. By creating more efficient buildings in NYC with the use of GPR, we are working to help reduce the contribution of carbon emissions in the city.
Every day we hear about the negative implications of climate change as pollution levels continue to rise and our carbon footprint increases in size every year.
To combat this, you might consider taking the train to work instead of driving. If it's convenient, you may separate your paper and plastics in the recycling bin. You might even be persuaded to buy a fuel-efficient car. But it's time to think bigger and consider investing in sustainable architecture as a way to greatly reduce the negative effects of climate change.
Many people are unaware of just how much buildings negatively impact the environment. In 2008, the Environmental Protection Agency (EPA) stated that buildings in the United States contributed to 38.9 percent of the nation's total carbon dioxide emissions, including 20.8 percent from the residential sector and 18.0 percent from the commercial sector.
Sustainable architecture focuses on building more efficiently by minimizing the footprint of the development site, using local and sustainable materials and incorporating more efficient mechanical systems, ultimately to minimize a building’s overall impact on the environment.
Sustainable architecture has the potential to change the way society views the environment. It is a well-known fact that architecture is able to shape our perspective and shift the cultural norm.
For example, a building owner can construct a traditional roof, but he or she might also want to consider a green roof with amenities for tenants. Not only is it more environmentally friendly, but there are property resale benefits as well. Make the green option the attractive option.
At Scott Henson Architect, we take pride in architectural sustainability. With knowledge in design, preservation, construction and more, let us help you build with an environmentally conscious mindset. Please contact us today!
