Building Automation System
ENGINEERING SERVICES –
TERMINOLOGY: “BUILDING AUTOMATION SYSTEM”
• Clipsal “CBUS” system• $21,000 Over & Above, Lighting Heating controls
7 Year payback period on ENERGY SAVINGS
• MOTION SENSOR• INFRA-RED (with Modulating Output)
• Lighting 300 LUX at the working plane• Heating Natural Gas Units Rinnai with
modified Computer Control Chips• Window Opening at high level by motorized
winders with limit controls • Automated Dampening Controls to Thermal Chimney• Security Proximity Card readers at primary access points 5NO
* Activates various programmes within computer controlled outputs.

LightingT5 FRI PHOSPHOROUS TUBES (ENERGY EFFICIENT)
• They come with Electrical Ballast• Hence dimmable by INFRARED MOTION SENSOR with
modulating output. i.e.1. Movement Activates – No movement (15 min.) Deactivation2. In active mode – modulates output to set LUX levels
300 LUX @ Working Plane3. Touch Control Override (i.e. Audio Visual Presentation)4. Time Variable / Ease of change – Preset Key Criteria
ESTIMATED COST / SAVINGS
• 1800 M2 say 2000M2
UFA GROSS• 500 Lights - 400 on @ any time
400 x 60 WATTS (Double Tubes)24 kw / hr (15 cents an hour)$3.60 / hr
Operation 1500 hrs a year
$5400 / annumAnnual Lighting Bill (Electrical)At 300 LUX – and not running when not needed
$2052 per Annum.
SAVE BETWEEN 25 – 50 % (38%)

HeatingBUILDING AUTOMATIONS SYSTEM
1. Computer allows heater to function2. Requires MANUAL activation but only
allows within pre-set time limits3. Will run for selected time:
.5 hr1.0 hr1.5 hr2.0 hr
4. No MOVEMENT within room (15 min.) computer will shut off heater
4. System will self modulate to internal preset thermostat, set 21DEGREES +-0 .5DEGREES
$1000 PER ANNUM.

Thermal ChimneyNIGHTIME PURGING
1. T1 / T2
Differential Thermostats (Inside / Outside)
Ambient Temperature Comparisons
IF: exceeds 21 DEGREES + tolerance
Opens DAMPNERS to thermal chimney
Open WINDOWS – if Rain Gauge indicates rain,
windows automatically close, and rely on greater time.
Will NOT allow heater, To engage self modulating thermostats

Access Control
1. 5 PRIMARY door sites – CBUS interface, plus Master Key
Action Plan – Environmental Sustainable Design
1. Schools Responsibility - Make a commitment to this system, to achieve the ideal ECOLOGICAL sustainable outcomes.
Make sure processors are put into place, so as the school community play vital role in achieving ECOLOGICAL results.
Upon occupancy a management training process will be required, to inform and educate the users of the buildingxs ESD attributes, this shall empower the users to take ownership and future management responsibilities.
2. Close windows / Lock Doors, generally
3. recyclable opportunities
4. Waste management
5. Air pollution
6. More effective use of energy resources
ORIENTATION
1. South Facing Light and appropriate shading provided by overhangs and verandahs
2. Material Selection / Thermal Mass / Low embodied energy
7. Alternative forms of energy
8. Use high quality natural materials, minimise chemically treated and
or synthetic materials.
9. Insulation (Thermal and Acoustically)
