Sustainable Sites: LEED BD+C Certification

The Sustainable Sites credit category is an important aspect of LEED BD+C certification, which focuses on promoting sustainable site selection, design, and development practices. The goal of this credit category is to minimize the environmental impact of a building project on the surrounding site, promote social and economic sustainability, and create a healthier and more sustainable environment for building occupants and the surrounding community. In this article, we will explore the key components of the Sustainable Sites credit category and the benefits of incorporating sustainable site practices in LEED BD+C certified projects.

Key Components of the Sustainable Sites Credit Category

The Sustainable Sites credit category includes various credits that are aimed at achieving sustainable site design and development. Some of the key components of the Sustainable Sites credit category include:

1. Site Selection: This credit encourages the selection of sites that are located in areas that minimize environmental impact and provide access to public transportation, amenities, and services. It also encourages avoiding sites with environmentally sensitive or protected areas, brownfields, and flood-prone areas.
2. Site Development: This credit focuses on the design and construction practices that minimize the disturbance of the site during construction, protect and restore natural habitats, and reduce stormwater runoff through practices such as green roofs, permeable pavements, and rainwater harvesting.
3. Open Space: This credit promotes the preservation and creation of open spaces on the site that provide access to nature, promote biodiversity, and create recreational opportunities for building occupants and the surrounding community.
4. Rainwater Management: This credit focuses on managing stormwater runoff through strategies such as rainwater harvesting, green roofs, and bioswales, which help reduce the impact of development on the site’s hydrology and water quality.
5. Heat Island Reduction: This credit encourages the use of strategies such as cool roofs, vegetated roofs, and shading devices to reduce the heat island effect, which can contribute to increased temperatures in urban areas.
6. Light Pollution Reduction: This credit aims to minimize light pollution from the building project by using outdoor lighting fixtures that are shielded and directed downward, reducing light trespass, and promoting dark sky-friendly outdoor lighting practices.

Benefits of Incorporating Sustainable Site Practices in LEED BD+C Certified Projects

Incorporating sustainable site practices in LEED BD+C certified projects can bring a wide range of benefits, including:

1. Environmental Sustainability: By selecting sustainable sites, protecting natural habitats, managing stormwater runoff, and reducing heat island effect and light pollution, LEED BD+C certified projects can minimize their environmental impact and contribute to the conservation of natural resources and biodiversity.
2. Social and Economic Sustainability: Sustainable site practices can also contribute to the social and economic sustainability of a project by providing access to public transportation, amenities, and services, creating recreational opportunities, and promoting economic development in the surrounding community.
3. Health and Well-being: Creating open spaces, preserving and restoring natural habitats, and reducing the heat island effect can improve the health and well-being of building occupants by providing opportunities for physical activity, connection with nature, and improved air quality.
4. Cost Savings: Sustainable site practices such as rainwater harvesting, green roofs, and permeable pavements can help reduce stormwater management costs, while strategies such as cool roofs and shading devices can help reduce energy consumption and associated costs.
5. LEED Certification: Incorporating sustainable site practices in a building project can help earn points towards LEED BD+C certification, which can enhance the project’s sustainability credentials, increase its marketability, and potentially qualify for financial incentives or regulatory benefits.
