PD04: Building HVAC&R resilience for a changing climate

Paul Stoller, Managing Director, Atelier Ten

Nicki Parker, Brisbane Sustainability Manager, Norman, Disney & Young

Lasath Lecamwasam, Building Services Engineer, ESBS Consultants

Yale Carden, Founder & Managing Director, GeoExchange Australia Pty Ltd

Greg Johnson, National Sustainability Manager, Stockland

The AIRAH Special Technical Group want to challenge the notion that resilience should cost the building owner more. Good resilient design should extend asset life, improve comfort and decrease running costs – resulting in lower whole-of-life cost.

Real life case studies demonstrating resilience in practice will be explored including; Stocklands’ approach to resilience across their portfolio and The Commons – residential resilience in heatwaves through good design. The role of technology in resilience will be examined in addition to Smart BMCS to pre-empt heat waves and more stringent testing conditions for equipment.

The soon-to-be-launched ‘Best Practice Guide for HVAC&R Resilience’, which covers the whole lifecycle of HVAC&R from Design, to Engineering and Installation, through to Maintenance and Operation, will be discussed in this session.

HVAC designers, manufacturers, installers, property owners, managers and advisors who want to safeguard and future-proof their buildings and assets for a changing climate should attend.

Managing Director of Atelier Ten’s Australian offices and global leader of its Benchmarking practice, Paul is recognized for environmental planning and design consulting work on large-scale campus, community and urban projects. Paul’s work in Australia includes major museum expansions in Sydney and Perth, a research laboratory in Adelaide, a tropical plant conservatory in Canberra, a six-building Precinct at ANU, the adaptive reuse of a former auto factory at Tonsley Park, and the thermal labyrinth at Federation Square in Melbourne. He has particular expertise in facade environmental performance optimisation expertise.





With nearly 12 years in Building Physics and Sustainability consulting, Nicki’s in-depth knowledge of applying complex principles to practical sustainable design provides value to built environment projects throughout the design cycle. Her specialist skills are focused around sustainable design solutions and advanced computational modelling techniques. She also has a keen interest in how climate change adaptation affects individual buildings.

Nicki has worked in a number of sectors to incorporate sustainability as a key driver in the buildings sector. Her background in building physics is crucial in understanding how a building works, allow project teams to pursue effective strategies, both from an energy consumption and cost perspective, and throughout the life of a building. This includes using climate change projections to quantify the potential impacts throughout the life of a development.

Nicki is a Green Star Accredited Professional (GSAP), the Vice-President for the Australian Affiliation of the International Building Performance Simulation Association (IBPSA), and co-chair on the Australian Institute of Refrigeration and Air Handling (AIRAH) Special Technical Group for Resilience.
