  2. • Temperature and Student Learning • Air Conditioning at San Diego Unified • Implementation Plan • Air Conditioned Spaces • Schedule • Design and Construction Cost • Minimize Impact to the General Fund • Energy Conservation Measures 2

  3.  “The preponderance of data of safety, absenteeism and efficiency …leads to the conclusion that human performance deteriorates rapidly at a temperature above or below a relatively narrow comfort zone.  Students experience approximately a two percent reduction in learning ability for every degree a room fluctuates from the optimum.” Council of Educational Facility Planners journal article by C. William Day 3

  4.  Researchers have been studying the temperature range associated with optimum learning for several decades and concluded:  Students perform mental tasks best when room humidity is between 40-70% and temperatures range from 68 to 74 degrees Fahrenheit  Teacher effectiveness and morale are similarly impacted by classroom temperature  Adequate Ventilation is essential Proper oxygen levels are also essential to achieving optimum performance in logical reasoning and arithmetic Source: EPA Study 4

  5.  1999 – Climate Study Initiated ◦ Established three climate zones  Zone 1 = coastal  Zone 2 = central  Zone 3 = inland  2001 – Ceiling Fan Initiative ◦ Board directed staff to utilize passive measures for hottest schools ◦ Ceiling fans, window tinting, etc.  2008 – Prop S passed; included A/C for Zone 3  2012 – Prop Z passed; included A/C for Zone 2  2013 – HVAC 2000 ◦ Board directed staff to expedite A/C for 2000 hottest classrooms 5

  6.  Expedited air conditioning in remaining qualifying spaces in all climate zones  Three-year implementation plan starting  in January 2016  Template approach: ◦ Standardized systems ◦ Individual, rooftop package units ◦ Fast-track process for design, ◦ DSA review and procurement  Separate expedited project and WSM  Minimize impact on schools during construction ◦ Work performed after school hours, including evenings, weekends, and vacations 6

  7.  Indefinite Delivery Indefinite Quantity (IDIQ) ◦ Competitively bid construction contracts based on estimated quantities ◦ Allows for a large amount of work across multiple sites in a condensed timeframe ◦ Individual A/C projects scheduled according to heat ranking  Whole Site Modernization (WSM) ◦ Schools scheduled to start their WSM by 2018, will receive A/C under that project ◦ HVAC will be incorporated into the overall WSM project design, Installation will be performed with other WSM work 7

  8.  Electrical Upgrades ◦ Sufficient electrical infrastructure required  A/C installation requires electrical infrastructure, transformers, switch gear, new conduit wiring and electrical panels ◦ Some schools will need power upgrades  Potential periods of power outages ◦ Requires coordination with utility company 8

  9.  Core classrooms, assembly areas, nurses’ offices and other primary use spaces: Permanent Classroom Occupational/Physical/Speech Therapy ◦ ◦ Non-Permanent Classroom Parent Rooms ◦ ◦ Assembly Space PE/Coaches Office ◦ ◦ Auditorium Pre-School/Headstart ◦ ◦ Cafeteria PrimeTime ◦ ◦ Career Center Principal/Staff Office ◦ ◦ Conference Rooms Reception/Waiting Area ◦ ◦ Core Support/Resource/Focus/Push- School Police Office ◦ ◦ in/Pull-out room Stage ◦ Counselor’s Office ◦ Student Center ◦ Custodial Office ◦ Study Hall ◦ Faculty Lounge or Dining ◦ Testing Room ◦ IDF/MDF Rooms ◦ Theatre ◦ Lecture Hall ◦ Vocational Classroom (excluding shops) ◦ Library ◦ Work Rooms ◦ Multi-purpose Room ◦ One-on-One Instruction/Small Group ◦ Nurse/Health Instruction/Behavior Modification Room ◦ 9

  10.  To conserve energy the following types of spaces will not be air conditioned: ◦ Kiln Rooms ◦ Interior Corridors ◦ Kitchens ◦ PE Prep ◦ Restrooms ◦ Weight Training ◦ Showers ◦ Wrestling Rooms ◦ Storage Spaces ◦ Dance Studios ◦ Supply Rooms ◦ Vocational Shops (Woodshop, Auto Shop, ◦ Team/Locker Rooms Metal Shop, etc.) ◦ Gymnasiums 10 10

  11.  DESIGN: Each A/C project at each school requires an architectural design and engineering plan Average duration three months ◦  DSA: Plans must be submitted to the Division of State Architect for review and approval prior to the start of construction ◦ Average duration three to six months  BID and AWARD: A construction contract for the performance of the A/C installations must be procured through the bid and award process ◦ Average duration four months  CONSTUCTION: Installation will occur either through an IDIQ contract or a WSM project ◦ Duration varies depending on type and quantity of spaces to be air conditioned 11 11

  12. Phase ase 1A - Proj oject ct Comple plete te $110M 0M Actual al • Board approved February 2013: 2,000 hottest classrooms • Climate Zone 3 schools and some Zone 2 schools • Air conditioning for classroom spaces • Projec ect t complete te Phase ase 1B - Ins nstal tallation lation 2016 $18M Estima timate ted • Continuation of A/C at Phase 1A sites • A/C for nurse’s offices, assembly areas, and other critical spaces • Project in design • Installation starts in early 2016 Phase ase 2 (Prop opose osed) d) - Inst stal allation lation 2016-2019 019 $204M 4M Esti tima mate ted • Expedited A/C for remaining qualifying spaces in all climate zones • Continuation of A/C in remaining spaces at Phase 1A sites 12 12

  13.  Additional Energy Cost Estimate: $2.8M Annually  Maintenance Cost Estimate: ◦ Initial Year Total: $2.15M - $1.4M (maintenance) - $750,000 (trucks, tools, and equipment) ◦ ◦ Ongoing: $1.4M per year (maintenance staff and materials)  Offsets: ◦ Concurrent Photovoltaic (PV) projects ◦ Modernization projects include insulation efficient windows, etc. ◦ A/C System Controls 13 13

  14.  Installation of solar panels at 16-20 schools ◦ Offset air conditioning consumption 10.5M KWhr/year ◦ $40M estimated construction/installation cost ◦ $2.8M estimated energy cost offset annually  PV at 8 schools designed for installation in 2016:  Nye ES  Zamorano ES  Penn ES  Mira Mesa HS  Tierrasanta ES  Morse HS  Scripps ES  Serra HS  PV at an additional 8-12 schools installed 2017 14 14
