New construction projects include design and construction of new buildings, and major renovations of existing ones. As defined by major programs like LEED, which has a rating system dedicated to new construction (LEED-NC), a major renovation involves major HVAC renovation, significant envelope modifications, and major interior rehabilitation.

In line with the LEED-NC emphasis, new construction often refers to new commercial office buildings, but many other commercial occupancy types can fall under this category, including hotels, mid- and high-rise residential, and institutional buildings such as libraries and schools.

Sustainability in new construction typically means a range of considerations:

• siting (e.g., locating near public transit, using previously developed land)

• water efficiency

• energy efficiency

• sustainable and healthy materials

• construction waste management

• indoor environmental quality
