Design for Sustainability in Airport Development Projects Tony Wallis – Associate - Beca Airports May 2009

Outline  Pavement Maintenance  Recycling Pavement Materials  New Technology  Stabilising Existing Materials In Situ  Use of Local Materials  Green Buildings

Bob the Builder says…  REDUCE  REUSE  RECYCLE

Maintenance - Crack Sealing and Injection

Maintenance – surface treatment

Auckland Airport – Recycling of Runway

Auckland Airport – Slabs Removed

Godzilla

Ohakea – AC Milling

AC Millings/Recycled Asphalt (RAP)

“Coolpave” – Warm Mix Asphalt

Stabilising

“Mudcrete”

Aitutaki – Local Coral

Other Initiatives  Green Procurement  Carbon Optioneering

Green Buildings - Why Go Green?

Drivers for Green Buildings  Climate Change  Ozone Layer Depletion  Waste Generation  Depletion of Natural Resources  Kyoto Agreement  Greenhouse Gases / Carbon Footprint  LOWER OPERATING COST

Buildings CONSUME  40% of the world’s raw resources (3 billion tons)  15% of its fresh water  40% of its energy  50% of the timber harvest The Building Industry – A Global View

Buildings PRODUCE  40% of solid waste to landfill  40% of harmful air emissions  35% of the world’s CO2 emissions The Building Industry – A Global View

Meridian Offices - Design Targets  Use 60% less energy than comparable buildings  Use 70% less water than comparable buildings

Auckland Airport – Pier B

Photovoltaics (PV) - Example

Solar Hot Water

Rainwater Reclaim - Example

Fabric / Facade Solutions

Water & Power Saving  Energy Audit – Meters  Lighting – automatic, sensors  Heating/Cooling – CO2 detectors, shading, ventilation  Building Management Systems  Variable Speed Motors – Baggage conveyors and travelators

Water & Power Saving  Solar/Wind Generators  Solar Water Heating  Airfield Lighting – LED/Solar powered lights  Water tanks  Low flow fittings
