2 Green California Schools Summit October 29, 2015 Chester A. Widom, FAIA California State Architect

3 GOVERNORS EXECUTIVE ORDER In almost every way conceivable, Californians have to get used to a very different world, and we re going to have to live just a little bit differently.

4 CALIFORNIA BUILDING CODE TITLE 24 Building Standards Commission Dept. of Housing & Community Development Office of Statewide Health Planning & Development Division of the State Architect

5 DEPARTMENT OF WATER RESOURCES TITLE 23 Model Water Efficient Landscape Ordinance (MWELO) Structure Planning and Designing Installation and Maintenance Managing Calculator Evapotranspiration Adjustment Factor (ETAF) Special Landscape Areas

6 MWELO Housing and Community Development ETAF: 0.55 Building Standards Commission ETAF: 0.45 OSHPD: Require local agency review and approval Division of the State Architect ETAF: 0.65

7 INCLUDED: K 12 AND COMMUNITY COLLEGE PROJECTS All New or Rehabilitated Irrigated Landscape New Campuses New Buildings on Existing Campuses

8 LANDSCAPE IRRIGATION REQUIRMENTS-1 All landscaping on new campuses must be 100% in compliance with MWELO requirements except that: ETAF for general landscape areas shall be 0.65 Additional water allowance of 0.35 for Special Landscape Areas ETAF for Special Landscape Areas of 1.0

9 LANDSCAPE IRRIGATION REQUIRMENTS-2 On existing campuses, compliance with the MWELO is required for: New landscape irrigation projects 500 SF or more in area. Rehabilitated landscape irrigation projects 1,200 SF or more in area. Projects 500 SF and < 2,500 SF may use prescriptive compliance method of MWELO Appendix D

10 LANDSCAPE IRRIGATION REQUIRMENTS-3 Rehabilitated landscape area requirements on existing campuses: Triggered by new building or addition to an existing building of 1,600 SF Existing landscape area equal to 75% of new building footprint or building addition footprint: Must be upgraded to comply with 2015 MWELO May be located on any campus within the district May include existing landscape area removed from service

11 THINK DISTRICT NOT CAMPUS Goal is the district s reduction of water usage Required landscape rehabilitation projects can be located in a variety of places: Adjacent to construction project Elsewhere on the campus Anywhere on other district campuses

12 THINK DISTRICT NOT CAMPUS Credit for MWELO compliant stand alone landscape irrigation projects for future construction projects If new building is placed on existing landscaped area, there is no requirement for additional landscape irrigation rehabilitation Credit for excess area

13 SELF CERTIFICATION Design Professional Architect Landscape Architect Civil Engineer Requirements Certification that design meets MWELO requirements-at project submittal Certification that construction conforms to MWELO requirements-at completion

14 DSA: A partner in the design and construction of great and safe schools.

15 Chester A. Widom, FAIA California State Architect (916)

16 DROUGHT RESPONSE BEST PRACTICES FOR CALIFORNIA SCHOOLS STRATEGIES FOR REDUCED WATER USAGE

17 EXECUTIVE ORDER B RESTRICTIONS TO ACHIEVE 25% OVERALL REDUCTION THESE REDUCTIONS MAY BE HIGHER OR LOWER DEPENDING ON YOUR LOCATION (8% - 36%) SCHOOLS MUST REDUCE WATER USE - EXECUTIVE ORDER APPLIES TO SCHOOLS

18 WHAT CAN SCHOOLS DO TO REDUCE THEIR WATER USAGE? PLANNING PLAY FIELDS ORNAMENTAL LANDSCAPING BUILDING USE MAINTENANCE EDUCATION

19 PLANNING CONTACT YOUR WATER PURVEYOR(S) TO DISCUSS AVAILABLE RESOURCES BENCHMARK EXISTING WATER USAGE CONSIDER INSTALLING SEPARATE METERS FOR INDOOR AND OUTDOOR USE ESTABLISH PRIORITIES FOR WATER CONSERVATION PLAY FIELDS AND OTHER EDUCATIONAL SPACES ORNAMENTAL LANDSCAPING BUILDING USES RAIN CATCHMENT/RECYCLED WATER SYSTEMS SUSTAINABLE SITES LOW IMPACT DEVELOPMENT

20 PLAY FIELDS PLAY FIELDS ARE REQUIRED EDUCATIONAL SPACES & MUST BE MAINTAINED FOR SAFETY STRATEGIES TO REDUCE WATER USAGE IN PLAY FIELDS FIELD USE ADJUSTMENTS/CONSOLIDATE FIELDS AERATE SOIL PLANT DROUGHT-TOLERANT GRASS VARIETIES USE AN IRRIGATION MANAGEMENT SYSTEM/MOISTURE SENSORS WATER EARLY MORNING OR AFTER SUNSET TO REDUCE EVAPORATION AVOID WATERING ON WINDY DAYS WATER DEEPLY, LESS FREQUENTLY TO DEVELOP DEEPER ROOTS ADJUST FERTILIZERS DURING WARMER MONTHS TO OPTIMIZE PLANT HEALTH ALLOW GRASS TO GROW LONGER, ESPECIALLY DURING THE SUMMER

21 ORNAMENTAL LANDSCAPING CONSIDER REPLACING ORNAMENTAL TURF WITH DROUGHT-TOLERANT LANDSCAPING MAINTAIN TREES SEPARATE IRRIGATION MULCH AROUND PLANTING AREAS USE PERMEABLE SURFACES FOR GROUNDWATER RECHARGE

22 BUILDING USE INSTALL HIGHER ACCURACY AUTOMATIC FLUSH TOILETS REPLACE OLDER PLUMBING FIXTURES WITH NEWER, WATER-EFFICIENT FIXTURES CONSIDER USING WATERLESS URINALS REPLACE SINK AERATORS, SHOWER HEADS, AND OTHER FITTINGS WITH LOW- FLOW FITTINGS USE METERED OR OPTICAL-SENSOR FAUCETS INSTALL INSTANT-HOT WATER HEATERS CONSIDER USING GRAY-WATER OR RECYCLED WATER SYSTEMS

23 MAINTENANCE REPAIR AND ADJUST IRRIGATION SYSTEMS REPLACE SPRINKLER HEADS WITH LOW-FLOW SPRINKLERS CAP OR PLUG UNNECESSARY SPRINKLERS CREATE A PROACTIVE LEAK-DETECTION SYSTEM CREATE A WEB PAGE AND PHONE HOTLINE TO REPORT BROKEN SPRINKLERS ADJUST STAFFING/COMMUNICATIONS SO REPORTED LEAKS ARE REPAIRED QUICKLY

24 EDUCATION INCORPORATE WATER CONSERVATION INTO THE CURRICULUM INFORM THE PUBLIC OF WATER CONSERVATION EFFORTS USE SIGNAGE TO TEACH STUDENTS AND PUBLIC ABOUT WATER WISE LANDSCAPING SHARE YOUR SUCCESSES WITH OTHERS

71 Power Purchase Agreement 6.2 MW 20 Sites The Water/Energy Nexus October 29,

72 Account for efficiency projects when sizing alternate energy project Chaparral: SCE tariffs make Co-Gen and Solar incompatible. Cannot feed energy to grid. Margarita: Prop. 39 projects will cut electicity usage by a third. Account for other changes that might take place over life of contract The Water/Energy Nexus October 29,

73 TVUSD will have spent all Prop. 39 dollars and touched four of thirty sites Many more projects than funding More complicated projects take much more time to put together. Best Practice: Leverage Prop 39 funds with other available funding The Water/Energy Nexus October 29,
