 “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

 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

• ptimum performance in logical reasoning and arithmetic

 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

 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

 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

 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

 Core classrooms, assembly areas, nurses’ offices and

• ther primary use spaces:
• Permanent Classroom
• Non-Permanent Classroom
• Assembly Space
• Auditorium
• Cafeteria
• Career Center
• Conference Rooms
• Core Support/Resource/Focus/Push-

in/Pull-out room

• Counselor’s Office
• Custodial Office
• Faculty Lounge or Dining
• IDF/MDF Rooms
• Lecture Hall
• Library
• Multi-purpose Room
• Nurse/Health
• Occupational/Physical/Speech Therapy
• Parent Rooms
• PE/Coaches Office
• Pre-School/Headstart
• PrimeTime
• Principal/Staff Office
• Reception/Waiting Area
• School Police Office
• Stage
• Student Center
• Study Hall
• Testing Room
• Theatre
• Vocational Classroom (excluding shops)
• Work Rooms
• One-on-One Instruction/Small Group

Instruction/Behavior Modification Room

 To conserve energy the following types of spaces will

not be air conditioned:

• Kiln Rooms
• Kitchens
• Restrooms
• Showers
• Storage Spaces
• Supply Rooms
• Team/Locker Rooms
• Gymnasiums
• Interior Corridors
• PE Prep
• Weight Training
• Wrestling Rooms
• Dance Studios
• Vocational Shops

(Woodshop, Auto Shop, Metal Shop, etc.)

 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

 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

 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  Penn ES  Tierrasanta ES  Scripps ES  Zamorano ES  Mira Mesa HS  Morse HS  Serra HS  PV at an additional 8-12 schools
