What is 'Open Space' credit and its benefit?

• A. Ensures some portion of the site provides open space for ecological and human health benefits
• B. It requires all open space to be developed into buildings
• C. Limits tree cover to less than 5%
• D. Reduces parking availability on site

Answer: (D)

Open Space is about reserving and integrating vegetated, accessible open space on the site to support ecological and human health benefits. This credit aims to preserve or create on-site areas—such as lawns, trees, and landscaped spaces—along with features that enhance stormwater management and microclimate, while providing a place for occupants to enjoy and benefit from nature.

That’s why the best description is a portion of the site being dedicated to open space that delivers ecological and human health benefits. The other ideas don’t fit: it doesn’t require all open space to be built over, it doesn’t set a max tree cover at a tiny percentage, and reducing parking, while common in sustainable design, isn’t the core focus of this Open Space credit.
