need pump and filter rooms on the interior for this. This
could also be viewable and educational.
There are plenty of roof surfaces for collection and this is the
cleanest source for collecting rainwater. Use gutters from
the roof to direct the water to storage tanks with overflow
into the storm system. For irrigation (on-site agriculture), use lighting should also be LED. Not only will these fixtures
this, or a larger retention area on site.
StorM WAter – coordinate with the site layouts and
parking, but use pervious surfaces for parking areas and
include bio-retention areas and swales or underground
storage and sediment traps so water leaving the site is as
clean as rainwater. See site drawings on the east side.
Native plants should minimize any need for decorative
irrigation, but irrigation should be available for any
community garden needs.
eLectricAL – it appears that most of the electrical will
need to be redone from the switchgear to the distribution to
the fixtures and devices. Any new equipment should be high
efficiency. Reduce the need for electrical power by using
high efficiency light fixtures and equipment and day-lighting
where possible.
Provide a PV (Photo-Voltaic) array, probably over the staff
parking area on the south side of the building (this will shade
parking as well). This will probably be tied into

the grid for net metering, but with advances in electrical
energy storage in the future, could be utilized to have the
facility completely “off the grid”.
Use LED (Light Emitting Diode) or magnetic induction
fixtures for long life and greater efficiencies. Exterior
use less electricity, but they also produce less heat in the
summertime to minimize additional
Use daylight and occupant controls for lighting. When there
is sufficient day lighting in an area, then electric lights should
be set to be off or dimmed. When a space is not occupied,
all lighting except emergency should be off.
Low voltage systems should include life safety; security;
telephone and data and any Audio/Video required. Ensure
coordination with the BAS.
fire protection – Will probably need to be
completely redone to upgrade to code, though some existing
piping may be able to be reused. A combination of wet
piping in conditioned areas and dry piping in unconditioned
areas will be required. it will not be necessary to tie the
sprinkler system into the captured water systems for the
building. The existing city service can be utilized for this.
glossary of terms
Low-e – Low Emissivity. Actually, low thermal emissivity -
is a quality of a surface that radiates, or emits, low levels of
radiant thermal (heat) energy. All materials absorb, reflect and
emit radiant energy. Emissivity is the value given to materials
based on the ratio of heat emitted compared to a blackbody,
on a scale of 0 to 1. A blackbody would have an emissivity
of 1 and a perfect reflector would have a value of 0. Ratio
of heat emitted compared to a blackbody, on a scale of 0 to
1. A blackbody would have an emissivity of 1 and a perfect
reflector would have a value of 0.
geo-thermal – Literally, “earth heat”. A system of using
the relatively consistent temperatures of the ground, or large
bodies of water, below a certain depth to transfer heat to (in
the summer) or transfer heat from (in the winter) rather than
burning fossil fuels or using electricity.
bAS – Building Automation System, also sometimes referred
to as Energy management System (EmS). A system of
sensors, meters and controls that monitors a building’s energy
and water usage, coordinates different requirements for the
different spaces and allows for automatic and manual control
of its equipment for optimum efficiencies and comfort.
commissioning – The term commissioning comes from
shipbuilding. A commissioned ship is one deemed ready for
