Help & SupportChapter 10-7.5: Green Building and Green Points Program
10-7.5-1 Legislative Intent and Purpose.
The purpose of this chapter is to protect the public health safety and welfare by regulating residential construction with the intent to conserve energy, water and other natural resources, preserve the health of our environment through optional and mandatory requirements related to design, construction, operations, recycling, and deconstruction This chapter has the following additional purposes:
(a) It provides criteria for rating the environmental performance of residential construction practices and provides guidelines for documentation that demonstrates conformance with the criteria;
(b) It encourages cost-effective and sustainable residential building methods, by encouraging conservation of fossil fuels, water and other natural resources, reduction of greenhouse gas emissions, recycling of construction materials, reducing solid waste and improving indoor air quality;
(c) It identifies the specific requirements for complying with the Green Points Program and how the program interfaces and exceeds the 2006 International Energy Conservation Code adopted in Chapter 10-7, "Energy Conservation and Insulation Code," B.R.C. 1981;
(d) It includes mandatory green building requirements to ensure that construction waste and deconstruction materials are recycled, reused, or otherwise diverted from land fills, and minimum requirements to ensure that dwellings are constructed in an efficient manner; and
(e) It includes provisions intended to provide for joint administration with the processing of building permits for remodeling, adding on, and constructing dwelling units.
Ordinance No. 7565 (2007)
10-7.5-2 Scope and Administration.
(a) Scope. The provisions of this chapter apply to the following:
(1) New construction, remodels, or additions to a dwelling, including without limitation single-unit dwellings, multi-unit dwellings, and dwellings within mixed use developments.
(2) Any two or more building permits for the same structure that are applied for in any 12 month period shall be considered as one application for the purpose of meeting the requirements of Sections 10-7.5-3, "Mandatory Green Building Requirements" and 10-7.5-4, "Resource Conservation – Green Points," B.R.C. 1981.
(3) The requirements of this chapter shall apply to construction activities of all types of dwellings unless the context clearly indicates otherwise.
(4) The requirements of this chapter are in addition to and do not replace the requirements within the Boulder Revised Code, including without limitation all of the life safety codes, the historic preservation ordinance, the land use code and the City of Boulder Design and Construction Standards.
(b) Administration. The Green Points Program shall be administered applied, and interpreted in accordance with Chapter 1, "Administration," Chapter 2, "Definitions," of the International Building Code (IBC) and the International Residential Code (IRC) as adopted with amendments by Sections 10-5-2, "Adoption of International Building Code with Modifications," and 10-5.5-2, "Adoption of International Residential Code with Modifications," B.R.C. 1981.
(c) Inspection and Compliance. No person shall fail to comply with the requirements of this chapter. No person shall construct in violation of a Green Points approval. All approvals and inspections of Green Point's applications and requirements shall be done in conjunction with a residential building permit application and field inspections. An application shall be made on a form that is approved by the city manager. The applicant shall demonstrate compliance with all of the provisions of this chapter prior to the issuance of a certificate of occupancy by the city manager.
(d) Exceptions. Any structure that includes dwellings that are pursuing a U.S. Green Building Council's LEEDT (Leadership in Energy and Environmental Design) Silver Certification or comparable green building rating certification or higher will be exempt from the Green Points requirements. No person that applies for this exception shall fail to complete the LEEDT certification process and receive such certification within six months after the final inspection on the building permit. The city manager may grant an extension to this time period if a request is made by the applicant and the applicant demonstrates a good cause as to why additional time is needed to complete the certification.

(c) Energy Efficiency – Additions and Remodels. An applicant for a building permit for a remodel or an addition to a dwelling that does not exceed the thresholds in subsection (b) above shall demonstrate that it meets the energy efficiency requirements of this section. A building permit for an addition to or a remodel of a dwelling unit shall meet one of the following standards:
(1) Requirement if upgrading the energy efficiency of the entire structure. The applicant may demonstrate that the entire building meets the HERS requirements that are described in Table 1B below; or
(2) Requirement for the new addition or the area of the house that is subject to a remodel. The applicant may demonstrate that the addition or the area of the building subject to a remodel meets the requirement of the IECC for the remodel area or addition as described in Table 1B below. Building permits under this requirement shall also meet the following:
(A) Complete a blower door test before application for the building permit to determine whether the building has a fresh air infiltration rate of no more than 0.5 natural air changes per hour (NACH) compliance rating. If this standard is exceeded, then the applicant shall meet the requirement of paragraph (B).
(B) Improve, repair and seal the dwelling unit, verified by a subsequent blower door test and prior to a certificate of occupancy or completion that demonstrates that:
(i) for buildings that had an air infiltration rate of 1.0 NACH or greater, then the building shall have a NACH 50 percent or less than the original blower door test,
(ii) for all other buildings, the building has an air infiltration rate of not greater than 0.5 NACH compliance rating.
