5. CHALLENGE & CONCEPT:
INCREASE PASSIVE DESIGN = REDUCE HVAC PLANT REQUIRED
The Challenge
(red items cannot be changed, everything else can!)

6. M&E CONCEPT : EARLY DISCUSSIONS WITH ARCHITECT
Can we Protect the Core AND Optimise Natural Daylight ?

7. M&E CONCEPT : EARLY DISCUSSIONS WITH ARCHITECT
Can we Protect the Core AND Optimise Natural Daylight ?
• Maximise North-light
• Reflective surfaces
• Views to Sky

8. M&E CONCEPT : EARLY DISCUSSIONS WITH ARCHITECT
Concept for Fresh Air Intake
• buried ‘Earth Tubes’ brings fresh air in from remote shaded
zone, with minimal air pollution (away from highways)
• “free” pre-cooling of fresh air via heat exchange with
steady ground temperature

9. M&E CONCEPT : EARLY DISCUSSIONS WITH ARCHITECT
Concept to integrate Internal Landscaping with M&E strategy
• Evaporative ‘adiabatic’ cooling effect
enhances comfort for occupants
• Plantations help to absorb CO2 and enhance
indoor air quality
• Helps to raise internal Relative Humidity to
enhance comfort
• Irrigated by rainwater harvesting system
