PHOTOVOLTAICS

• We have installed about 170kW of PV panels on the
  roof of Lounibos with great success- and some
  large rebates from PGE. We are just completing a
  255KW PV system at the Public Safety Training
  Center in Windsor which will produce 100 of
  their electrical needs and will generate some
  surplus to sell back to the utility. Our rebate
  on this system will be about 740,000. We will be
  installing a 144KW PV system on the roof of
  Plover as part of the current remodel, and that
  should be operational in about 3-4 mos. The
  rebate on that system will be about 420,000.

PHOTOVOLTAICS

• We installed a 44KW PV system on the roof of the
  new Doyle Library and it is online now, with a
  readout of its production available to the public
  from an info kiosk in the 1st floor entry foyer.
  That rebate was about 136,000. We took a request
  to the Board Facilities Committee to begin the
  research on a large PV array for the roof of
  Haehl Pavillion, and I hope that we can do that
  project in the coming year or so. I would also
  like to look at the roof of Emeritus for a future
  PV array.

PHOTOVOLTAICS

• SRJC investigated the feasibility of placing a PV
  array on the new parking structure but with the
  height limitations, the College was trying to
  keep its building profile as unobtrusive as
  possible. The College continues to explore this
  and other Santa Rosa Campus sites for future
  photovoltaic projects.

COGENERATION

• In 1989 we installed a 240 KW cogeneration system
  at Quinn, and about 3 years ago we replaced it
  with a more updated 280 KW system. It not only
  supplies the hot water for heating the pools,
  space heating for Quinn, Tauzer, Maggini,
  Barnett, and Bailey, but it also supplies chilled
  water for air conditioning in Maggini and Bailey.
  As a by-product of the hot water production it
  has turbines in the engines which generate
  electricity for our grid. In addition to saving
  about 90,000 per year in electrical costs, we
  are going to receive a 168,000 rebate from PGE
  for it.

LOAD SHEDDING

• In the new Doyle Library our air conditioning
  system consists of a large ice maker which runs
  at night, making ice with low cost night time
  power. In the day we circulate water through the
  ice and back into the building to provide cooling
  at a fraction of the cost of a conventional A/C
  system. We are looking at ice making A/C systems
  now for several of our existing buildings. This
  type of load shedding is a major focus of PGE
  right now since it reduces their need to build
  new plants. There are substantial rebates
  available now as well.

UNDER FLOOR DISTRIBUTION

• In the remodeled Plover, the new Mahoney Library
  in Petaluma, and the large classroom/office
  building (Call Hall) in Petaluma we will be
  moving the conditioned air under a raised floor
  system which will allow us to cool the buildings
  using 65 degree air instead of the 55 degree air
  more typically needed in conventional A/C
  systems. This will save a great deal of energy
  and money by not having to cool the air an
  additional 10 degrees. It works well because the
  65 degree air passes up from a register near your
  work station and is 33 degrees cooler than your
  body temperature, and so it feels very cool.
  Conventional A/C systems are trying to push 55
  degree air down from the ceiling, through the
  layer of warm air that is always at the top of
  the room, and this is inefficient. This is a
  European technology that is gaining widespread
  acceptance in the US, and we will have the first
  such systems in Sonoma County.

RACE HEALTH SCIENCES BUILDING, IDEC

• In Race we installed an A/C system that has won
  numerous regional and national engineering awards
  and is regularly used as a demonstration system
  by PGE. It consists of a large attic mounted fan
  system which blows outside air over large grills,
  like your car radiator, that have street
  temperature water running down them. This blowing
  air causes evaporation, releasing heat out of the
  building, and provides cool air to the building.
  The mechanical chiller rarely has to go on except
  when outside temperatures exceed 90-95 degrees.
  The system is called an Indirect/Direct
  Evaporative Cooling system (IDEC), and is what we
  will use to cool Plover and several of the new
  buildings in Petaluma. PGE figures it saves
  40-50 of the energy of a conventional system.

12
BERTOLINI STUDENT CENTER

• In the new student center we will be installing a
  Ground Source Heat Pump system using water from
  geothermal wells. We will drill several hundred
  6 diameter wells, each about 300 deep, in the
  Burbank Circle Dr. They will supply a constant 55
  degree ground water as a preconditioned water
  source for air conditioning. The water will pass
  over heat exchangers to cool air, which will then
  be distributed through the building. Since we are
  typically seeking 55 degree air for A/C use, this
  supplies us with it for free, and if it needs
  additional cooling we use small heat pumps to
  drop the temperatures a few more degrees. This is
  much more efficient than trying to chill 80 or 90
  degree outside air down to 55 degrees. For
  heating we just reverse the system- it supplies
  55 degree water to the heat exchangers instead of
  30 or 40 degree outside air and so heating this
  55 degree air up to room temps is much more
  efficient.

GREEN BUILDING

• All of our newer buildings incorporate green
  building technologies and materials, and as that
  market expands and more products are available,
  we will insist that they be used. The architects
  and engineers we use are well versed in this and
  know what our requirements are, from 100
  recycled content in new carpets and upholstery,
  to counter laminates and wall coverings made from
  recycled wood byproducts, to vinyl flooring made
  from all natural linoleum components such as
  linseed oil, jute, and cork. Our interior
  finishes no longer contain any products with
  volatile oils that off gas allergens. Even the
  glues used to secure flooring, laminates, and
  wall coverings are water based, as are all of our
  floor finishing products. Our pitched roofs are
  concrete tile with no petroleum content and our
  exterior finishes are brick, plaster, and
  concrete. We just completed installation of
  interior lighting motion sensors in 9 classroom
  buildings which will save considerable electrical
  energy, and we are now completing a 2 year
  project to replace every boiler in the district
  that is over 20 years old with new, highly
  efficient modular boilers. We are in the process
  of replacing our 24 year old computerized energy
  management system (EMS) which controls the HVAC
  systems in all buildings with a new and much more
  efficient and effective system. As other new
  green products and technologies become feasible
  we will incorporate them.

ALTERNATIVE VEHICLES

• In recent years we have been replacing our older
  fleet vehicles with electric and hybrid vehicles
  wherever practical. You may have noticed the
  large number of electric carts on campus being
  used by maintenance folks, the warehouse,
  Computing Services, and Graphics. We hope to
  continue buying them and have only been
  constrained by their fairly limited availability
  and light duty nature. There are only a few
  vendors for them that have been able to stay in
  business for any length of time (long term
  availability of parts and warranty protection is
  the issue here) and we have found that they are
  often not heavy duty enough to handle some of the
  loads and tasks that are needed. We continue to
  look at new vendors, however, and to test new
  products in this area. We have had great success
  with our first hybrid vehicle and hope to
  purchase more hybrids soon.

RECYCLING

• SRJC has recycling program goals of 25 the first
  year, 50 after 3 years, and our achievement a
  couple of years ago of about 67 reduction in
  our waste stream. This years report to the state
  demonstrated about a 75 reduction in our waste
  stream, with deversions of construction waste,
  green waste, paper/plastic/metal, and other
  materials at all time highs. Our recycling
  program leads the state community college system
  and is considered a model program.

16
BICYCLES

• We have just completed the installation new bike
  racks all over campus and now have over 600 racks
  in place. We also applied for, and received, a
  grant to buy secure bike storage units with
  electronic locks. Once those are in place and we
  can evaluate their usage and effectiveness we may
  purchase more. Some will be installed in the new
  parking structure and we plan to install
  conventional bike racks in the new garage as well.
