FIGURE 13.17 A green building incorporates design features to minimize its ecological footprint.
Made from sustainable materials, green buildings are built to minimize energy use and water use, protect their
occupants’ health, limit pollution, and recycle waste.

TABLE 13.3 Green Building Approaches for LEED Certification CHAPTER 13 • THE URB AN ENVIR ONMENT : CREATING SUSTAIN ABLE CITIES
APPROACHES THAT ARE REWARDED MAXIMUM POINTS
ENERGY: Monitor energy use; use efficient design, construction, appliances, systems, and lighting; use clean, 37
renewable energy sources
THE SITE: Build on previously developed land; minimize erosion, runoff, and water pollution; use regionally 21
appropriate landscaping; integrate with transportation options
INDOORS: Improve indoor air quality, provide natural daylight and views; improve acoustics 17
MATERIALS: Use local or sustainably grown, harvested, and produced products; reduce, reuse, and recycle 14
waste
WATER USE: Use efficient appliances inside; landscape for water conservation outside 11
POINTS ABOVE MAY TOTAL UP TO 100. THEN, UP TO 10 BONUS POINTS MAY BE AWARDED FOR:
INNOVATION: New and innovative technologies and strategies to go beyond LEED requirements 6
THE REGION: Addressing environmental concerns most important for one’s region 4
Out of 110 possible points, 40 are required for LEED certification, 50 for silver, 60 for gold, and 80 for platinum levels. Point allocation shown is for
new construction. Allocation varies slightly for renovations and specific types of buildings. 367
