  Application: This checklist shall be used for nonresidential projects that meet the following: new construction, or building additions of 1,000 square feet or greater, or building alterations with a permit valuation of $200,000 or more pursuant to Section 301.3, AND are adopting Tier 1 voluntary measures.

  Note: All applicable mandatory requirements in Chapter 5 shall be met prior to applying Tier 1 voluntary measures.

  Instructions:

  Comply with all Tier 1 prerequisite measures from the various categories shown on the table below.

  Add a “ Y ” to all mandatory and Tier 1 prerequisite measures in the appropriate columns.

  Select the required number of additional electives from those categories shown on the table below and add a “ Y ” on the selected elective and add an “ N ” on the rest.

  Count the total number of Tier 1 prerequisite measures plus the additional electives and write down the total number at the end of the checklist. Determine if the required number of Tier 1 measures have been selected to achieve Tier 1 compliance.

  Y = Yes (section has been selected and/or included) N = No (section has not been selected and/or included) O = Other (provide explanation)

  [N] = New construction pursuant to Section 301.3

  4. Open parking garages of any size, or open parking garage areas, of any size, within a structure.

  Note: For the purposes of this section, unconditioned shall mean a building, area or room which does not provide heating and/or air conditioning.

  Informational Note:

  1. Functional performance testing for heating, ventilation, air conditioning systems and lighting controls must be performed in compliance with the California Energy Code.

  5.410.2.1 Owner’s or Owner representative’s Project Requirements (OPR). [N] The expectations and requirements of the building appropriate to its phase shall be documented before the design phase of the project begins. This documentation shall include the following:

  1. Environmental and sustainability goals.
  2. Building sustainable goals.
  3. Indoor environmental quality requirements.
  4. Project program, including facility functions and hours of operation, and need for after hours operation.

  6. Building occupant and operation and maintenance (O&M) personnel expectations.

  5.410.2.2 Basis of Design (BOD). [N] A written explanation of how the design of the building systems meets the OPR shall be completed at the design phase of the building project. The Basis of Design document shall cover the following systems:

  1. Renewable energy systems.

  2. Landscape irrigation systems.

  3. Water reuse systems.

  5.410.2.3 Commissioning plan. [N] Prior to permit issuance a commissioning plan shall be completed to document how the project will be commissioned. The commissioning plan shall include the following:

  SECTION 304—VOLUNTARY TIERS

  304.1 Purpose. Voluntary tiers are intended to further encourage building practices that improve public health, safety and general welfare by promoting the use of building concepts which minimize the building’s impact on the environment and promote a more sustainable design.

  304.1.1 Tiers. The provisions of Divisions A4.6 and A5.6 outline means, in the form of voluntary tiers, for achieving enhanced construction levels by incorporating additional measures for residential and nonresidential new construction. Voluntary tiers may be adopted by local governments and, when adopted, enforced by local enforcing agencies. Buildings complying with tiers specified for each occupancy contain additional prerequisite and elective green building measures necessary to meet the threshold of each tier. See Section 101.7 of this code for procedures and requirements related to local amendments, additions or deletions, including changes to energy standards.

  [BSC & HCD] Where there are practical difficulties involved in complying with the threshold levels of a tier, the enforcing agency may grant modifications for individual cases. The enforcing agency shall first find that a special individual reason makes the strict letter of the tier impractical and that modification is in conformance with the intent and purpose of the measure. The details of any action granting modification shall be recorded and entered in the files of the enforcing agency.

  SECTION 305 [OSHPD 1]— CALGreen TIER 1 AND CALGreen TIER 2

  305.1 CALGreen Tier 1 and CALGreen Tier 2 buildings contain voluntary green building measures necessary to meet the threshold of each level.

  305.1.1 CALGreen Tier 1. To achieve CALGreen Tier 1, buildings must comply with the latest edition of “Savings By Design, Healthcare Modeling Procedures” found online at http://www.energysoft.com/main/page_ downloads_ sbd_healthcare.html.

  305.1.2 CALGreen Tier 2. To achieve CALGreen Tier 2, buildings must exceed the latest edition of “Savings By Design, Healthcare Modeling Procedures” by a minimum of 15 percent.

  SECTION 306 [DSA-SS]—VOLUNTARY MEASURES

  306.1 Purpose. For public schools and community colleges, voluntary measures further encourage building practices that improve public health, safety and general welfare by promoting the use of building concepts which minimize the building’s impact on the environment and promote a more sustainable design.

  306.1.1 Appendix A5, Divisions A5.1 through A5.5, outline means of achieving enhanced sustainable design and construction by incorporating voluntary measures that exceed the mandatory measures.

  306.1.2 Chapter 5 Nonresidential Mandatory Measures that are not adopted as mandatory measures by DSA-SS are voluntary measures recommended and encouraged for the design, construction, verification and maintenance of non-energy systems.

  Note: The building commissioning requirements for energy efficiency specified in the California Energy Code are required.
