The Boulder Green Points Building Program is a mandatory residential green building program that requires a builder or homeowner to include a variety of sustainable building components based on the size of the proposed structure. Similar to the US Green Building Council's LEED program, the Boulder Green Points program awards points for a menu of sustainable building practices. Renewable energy technologies are among the optional components a builder can use to earn points. In addition to green points requirements, new construction projects also must show energy efficiency compliance through the Home Energy Rating System (HERS). The required HERS index varies according to the size of the dwelling.
The Green Building Green Points program for residential remodels and additions includes tiered, above-code energy efficiency (between 15 to 50 percent depending on the size of the addition), lighting, and air sealing requirements. An addition often warrants the same energy efficiency compliance as new construction; applicants can check guidelines for thresholds.
In 2009, there were [http://www.bouldercolorado.gov/index.php?option=com_content&task=view&id... changes] passed to the building and electrical codes, and green building requirements were expanded to commercial buildings. Multi-family residential units are also included: each dwelling in a multi-unit dwelling is required to meet the green point requirements separately.
