Chula Vista Green Building Standards (Plan Check Version for Submittals)

Per Chula Vista Municipal Code Chapter 15.12, Green Building Standards, the following green building measures shall apply to all new residential construction, remodels, additions, and alterations, and to all new nonresidential construction, remodels, additions, and tenant improvements.

Definitions
  • Building Official means the officer or other designated authority charged with the administration and enforcement of this chapter, or duly authorized representative.

  • Composite wood products include hardwood plywood, particleboard, and medium density fiberboard. Composite wood products does not include hardboard, structural plywood, structural panels, structural composite lumber, oriented strand board, glued laminated timber as specified in “Structural Glued Laminated Timber” (ANSI A190.1-2002) or prefabricated wood I-joists.

  • Energy Code means the California Energy Code, as adopted and amended by the City in Chapter 15.26 of the Municipal Code.

  • Green Building means a holistic approach to design, construction, and demolition that minimizes the building’s impact on the environment, the occupants, and the community.

  • Infiltration means an uncontrolled inward air leakage from outside a building or unconditioned space, including leakage through cracks and interstices, around windows and doors and through any other exterior or demising partition or pipe or duct penetration.

  • MERV means filter minimum efficiency reporting value, based on ASHRAE 52.2-1999.

  • Moisture content means the weight of the water in wood expressed in percentage of the weight of the oven-dry wood.

  • Outdoor Air (Outside air) means air taken from outdoors and not previously circulated in the building.

  • VOC means volatile organic compound and is broadly defined as a chemical compound based on carbon chains or rings with vapor pressures greater than 0.1 millimeters of mercury at room temperature. These compounds typically contain hydrogen and may contain oxygen, nitrogen and other elements. See California Code of Regulations (CCR) Title 17, Section 94508(a).
Standards

Buildings and building sites shall be designed to include the following green building measures: Storm Water Management and Discharge Control. Municipal Code Section 14.20

  1. Construction Waste Reduction, Disposal and Recycling. Municipal Code Section 8.25.095
  2. Energy Efficiency.  Buildings shall meet the requirements of the Chula Vista Municipal Code Section 15.26
  3. Air Sealing.
    1. Joints and openings. Openings in the building envelope separating conditioned space from unconditioned space must be sealed by a method acceptable to the building official.
    2. Other openings.  Whole house exhaust fans shall have insulated louvers or covers that close when the fan is off. Covers or louvers shall have a minimum insulation value of R-4.2.
  4. Water Use
    1. Indoor Water Use
      1. 20% Savings.  A schedule of plumbing fixtures and fixture fittings that will reduce the overall use of potable water within the building by 20% shall be provided.  The reduction in potable water use shall be demonstrated by one of the following methods.
        1. A calculation demonstrating a 20% reduction in the building “water use baseline” as established in Table 1 shall be provided, or
        2. Each plumbing fixture and fitting shall meet the 20% reduced flow rate specified in Table 2.
      2. Multiple showerheads serving one shower shall not exceed the maximum flow rates specified in the 20% reduction column contained in Table 2 or the shower shall be designed to only allow one showerhead to be in operation at a time.

Fixture “Water Use” = Flow rate x Duration x Occupants x Daily uses

  • Except for low-rise residential occupancies, the daily use number shall be increased to three if urinals are not installed in the room.1
  • The Flow-rate is from the CEC Appliance Efficiency Standards, Title 20 California Code of Regulations; where a conflict occurs, the CEC standards shall apply.2
  • For low rise residential occupancies, the number of occupants shall be based on two persons for the first bedroom, plus one additional person for each additional bedroom.3
  • For non-residential occupancies, refer to Table A, Chapter 4, 2007 California Plumbing Code, for occupant load factors. 4
