Strategic placement of hardscape on LEED certified projects minimizes the amount of impervious areas, as stipulated by the USGBC for LEED Green Associates.
In the realm of sustainable site development, a key consideration is managing impervious surfaces, particularly in the context of LEED (Leadership in Energy and Environmental Design) certification. This approach has been championed by the U.S. Green Building Council (USGBC).
One of the advantages of maintaining pervious surfaces is their ability to filter pollutants, making them a valuable asset in urban environments. These surfaces, such as soil and vegetation, allow water to percolate into the ground, reducing runoff and helping to combat flooding.
Hardscape elements, essential for functionality and accessibility, are often concentrated in specific areas. However, the strategic placement of these elements can have a significant impact on the sustainability of a project. The USGBC has developed a strategy for LEED projects that involves strategically placing functional and decorative hard decks to reduce the amount of impermeable surfaces on construction sites.
By strategically locating hardscape elements, it is possible to minimise the total area of impervious surfaces. This not only benefits the environment by allowing more water to infiltrate the ground, but also helps to mitigate the urban heat island effect. This phenomenon, characterised by urban areas being significantly warmer than their surrounding rural areas, can be alleviated by maintaining a higher proportion of pervious area.
Moreover, preserving more of the site's natural pervious surfaces supports local ecosystems. By doing so, projects can earn points towards LEED certification, further demonstrating their commitment to sustainability.
Another benefit of maintaining a higher proportion of pervious area on a site is the recharge of groundwater. This is crucial for maintaining healthy water levels and ensuring the long-term sustainability of the site and its surroundings.
In conclusion, the strategic placement of hardscape elements and the maximisation of pervious area are crucial considerations for sustainable site development. These practices not only reduce the environmental impact of construction projects, but also contribute to the health and well-being of local ecosystems and communities.
