  3. 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. Legend Computer Heater Lights Dampners Motion Sensor Windows

  4. Lighting T5 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.) Deactivation 2. In active mode – modulates output to set LUX levels 300 LUX @ Working Plane 3. 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 / annum Annual Lighting Bill (Electrical) At 300 LUX – and not running when not needed $2052 per Annum. SAVE BETWEEN 25 – 50 % (38%)

  5. Heating BUILDING AUTOMATIONS SYSTEM • Computer allows heater to function • Requires MANUAL activation but only allows within pre-set time limits • Will run for selected time: .5 hr 1.0 hr 1.5 hr 2.0 hr Increments • No MOVEMENT within room (15 min.) computer will shut off heater • System will self modulate to internal preset thermostat, set 21DEGREES +-0 .5DEGREES $1000 PER ANNUM. (conservative) Natural gas is cheap Legend Computer Heater Motion Sensor Tempreture (DEGREES)

  6. Thermal Chimney NIGHTIME PURGING • 12:00 Midnight to 2:00 AM Requires natural air / Pressure to cause movement DAYTIME CONTROL • 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 Legend Computer Thermostat Rain Gauge Windows Heater Dampners

  7. WATER EFFICIENCY DIVICES • Tap Timers EQUATION 15 LITRES / PER DAY / PER PERSON 2 Drinking 2 Washing 12 Flushing --- 15 LITRES x 250 STUDENTS --- 3750 LITRES (say 3500) Multiply 200 days per year --- 700,000 LITRES / YEAR RAIN WATER HARVESTING $15,000 INVESTMENT

  8. EQUATION 25 YEAR RAINFALL – AVG. 600 mm / PER YEAR TANK SIZE – 2.4 H x 3.0 D 15 LITRES x 2 = 40,000 LITRES 30,000 --- 700,000 30,000 23 Times. (Hence, needs to rain every fortnight) --- 1800m2 Floor Area Available 1000m2 Collection Area (Roof) X 600 mm 0.6 / m2 --- $1.0833 cents per 1000 LITRES $0.9026 cents per 1000 LITRES RAIN WATER HARVESTING $15,000 INVESTMENT 1st of July $1.98 (Say $2.00) --- 240,000 LITRES @ 1 year --- $480 / Year (Say $500 Year) INVESTMENT $15,000 30 YEAR PAYBACK

  9. Access Control • 5 PRIMARY door sites – CBUS interface, plus Master Key Action Plan – Environmental Sustainable Design • 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. • Close windows / Lock Doors, generally • recyclable opportunities • Waste management • Air pollution • More effective use of energy resources • Alternative forms of energy • Use high quality natural materials, minimise chemically treated and or synthetic materials. • Insulation (Thermal and Acoustically) ORIENTATION • South Facing Light and appropriate shading provided by overhangs and verandahs • Material Selection / Thermal Mass / Low embodied energy
