High Performance School (CHPS) Requirement

a. All new schools and new occupiable and conditioned buildings on existing campuses shall, at a minimum qualify as a CHPS project as defined in the version of CHPS “Best Practices Manual Volume III, Criteria”, applicable at the time the project is submitted to the Division of State Architect (DSA). (CHPS Volume III is available at www.chps.net)

b. The District seeks to meet as many CHPS criteria as economically feasible. Defining characteristics are listed in Section A.3, above. Some are referenced in this “School Design Guide” as specific LAUSD requirements for new schools. Others are included in the CHPS Best Practices Manual, “Volume II, Design” and “Volume III, Criteria.”

c. To achieve these goals, the District advocates an integrated "whole building" design approach to maximize the interactive affects of good practice and the District’s criteria and requirements. Key systems and technologies must be considered together from the beginning of the design process, at preliminary schematic design and optimized for long-term performance.

d. Architects shall submit a CHPS Scorecard (see Appendix “A.1”) at the following milestones:

1. Schematic Design: Forecast of CHPS points anticipated to be achievable supported by project Basis of Design and preliminary plans.

2. Design Development: Detailed account of CHPS points achieved in the school design with supporting references to specific narratives, plans, specifications and cut sheets in the submittal.

3. Construction Drawings (50%): Detailed account of CHPS points to be achieved in the school design with supporting references to specific narratives, plans, specifications and cut sheets in the submittal.

4. Final Design (100% Construction Drawings): Final accounting of CHPS points achieved with the signature of the registered project architect.

5. Construction Completion: Final accounting of CHPS points achieved with the signature of the registered project architect. 2. CHPS Specifics

1. CHPS Best Practices Manual “Volume III, Criteria” defines many prerequisites and optional credits that address a wide range of high performance design opportunities. The following topics address key areas of priority to the District.

a. Lighting and Daylighting

1. Electric lighting standards and control requirements are described in the Electrical Power and Lighting section of this “School Design Guide.”

2. Adequate daylighting, integrated with electric lighting and controls, is required in all classrooms.

3. Lighting and daylighting shall be designed and calculated in accordance with the criteria and examples included in the Southern California Edison “Classroom Lighting Guidelines.” For daylighting, this approach requires computer analysis – utilizing a CHPS-approved methodology (see CHPS “Volume III, Criteria, IEQ Credit Daylighting”).

b. Energy Performance

1. By integrating the design of all building components to increase energy efficiency, the source energy requirement of each proposed new school shall be a minimum of 15% better than required by the California Energy Efficiency Standards (Title 24) in force at the time the project is submitted to DSA, unless compelling justification is provided to the District for a lower efficiency. Under no circumstances shall any new school perform less than 10% better than Title 24.

c. Acoustics

1. Analyze the acoustical environment of the site (such as traffic) and the characteristics of planned building components (such as HVAC), and design to minimally achieve a classroom acoustical performance of 45 dBA background noise level (unoccupied with HVAC system on) or better (see CHPS “Volume III, Criteria,” IEQ Prerequisite Minimal Acoustical Performance and Credit Improved Acoustical Performance).

2. While the desired performance target of 35 dBA may not be practicably achievable, the Architect shall explore innovative design options for obtaining its speech cognition goal with wall and ceiling reflective surfaces, strategically placed absorptive surfaces, and voice reinforcement systems.

3. For additional criteria, refer to the District’s “Acoustical Requirements” (in Appendix “A.3”).

d. Indoor Air Quality

1. Appropriate design strategies shall be utilized to ensure healthy indoor air quality (see CHPS “volume III, Criteria,” IEQ Prerequisite Indoor Air Quality Minimum Requirements).The issues that shall be addressed include minimum outside aire ventilation, HVAC design and air filtration, and moisture control.

2. During construction, steps must be taken to provide CHPS- mandated temporary construction ventilation; dust protection; product preconditioning; sequencing; vacuuming and duct cleaning; building flush-out; and post-occupancy ventilation (see CHPS “Volume III, Criteria,” IEQ Prerequisite Indoor

Air Quality Minimum Requirements).

e. Commissioning

1.The District will provide CHPS-compliant commissioning services for all new school building construction(see CHPS “Volume III, Criteria, Energy Prerequisite Fundamental Building

Systems Testing and Training and Credit Enhanced Commissioning).

The Architect shall assist the District-appointed Commissioning Agent as required, and incorporate in the Contract Documents the necessary provisions specifying the General Contractor commissioning-related tasks, including Division 1 to 16 Specification Section(s), Commissioning

Plans, and other documents. Contact the District representative for further information.

2. The required “Basis for Design” must be complete with all design parameters, assumptions and criteria (not simply a reference to LAUSD design guidelines) so it intent is fully available to the Commissioning Authority.

f. Water Efficiency

1. To the maximum extent feasible, incorporate landscaping and interior water efficiency strategies as listed in Section A3e, above. Develop a water use budget for exterior and ornamental water use as specified in design Guide Section 3.9.D.1 Planting and Irrigation, Irrigation Design Requirements (see CHPS “Volume III, Criteria,” Water Prerequisite Create Water Use

Budget)

g. Storm Water Management

1. Utilize the LAUSD “Post-Construction Storm Water Management Plan” (“BMP Selection White Paper”) and accompanying Check List for site planning for enhanced water quality and for the selection of appropriate Best Management Practices. (See also CHPS “Volume III, Criteria,” Credits Limit Stormwater Runoff and Treat Stormwater Runoff.

h. Construction Waste Management

1. Establish a minimum non-hazardous construction and demolition debris recycling requirement of 75% by weight as defined in Specification 01340, Construction & Demolition Waste Management (see also CHPS “Volume III, Criteria,” Materials Prerequisite Construction Site Waste Management).

i. Materials

1. To the maximum extent feasible, specify CHPS-compliant low emitting materials (see CHPS Best Practices Manual “Volume III, Criteria,” IEQ Credit Low-Emitting Materials). On its website, CHPS maintains a list of low emitting materials. j. Educational Displays

1. Provide at least one permanent education display on the school site that describes the high performance features that are part of the school’s design (see CHPS “Volume III, Criteria, Prerequisite Educational Display).

k. High-Performance Schools

1. For specific schools or buildings, the District may elect to increase the utilization of CHPS “Best Practices” – especially those in “Volume III, Criteria” – to improve “green” performance and obtain incentive funding.
