Presentation Transcript

  1. Sustainability: Measurement and Valution Evidence from Australia and New Zealand Georgia Warren-Myers Dr Richard Reed

  2. Introduction • Background • Sustainability and Rating Tools • Role of Valuation • Methodology and Results • Measurement of Sustainability • Market Value and Industry Rating Tools • Conclusions and Further Research

  3. Background • Need to identify the relationship between sustainability and value • Australian and New Zealand Investors and Sustainability • Lack of Evidence • Valuers have a pivotal role

  4. Sustainability & Rating Tools • Sustainable buildings are not a ‘kit home’ • What is sustainability? • Industry Environmental Rating Tools • NABERS • Green Star • Potential issues • What constitutes sustainable?

  5. Role of Valuation • Impact of Sustainability on Value? • ‘Market Value’ • 5 Approaches of Determination – however commercial property use DCF and Capitalisation of Income approaches • A ‘sustainable’ office building is not a ‘new’ form of property - it still maintains the primary purpose of a commercial building • Issues for Valuers

  6. Methodology & Results • Part of a larger study • Objective • Australian and New Zealand fieldwork • Investors • 9 semi-structured questions • Interview • Valuers • Questionnaire • 16 questions • 2007-2008

  7. Measurement of Sustainability • Investor and Valuer opposing opinions! • Also slightly different perceptions between NZ and Australia • Investors value performance • Valuers want a rating • New Zealanders want both!

  8. Investor Perceptions on the distribution of preference for Design Ratings or Building Performance

  9. Valuers’ Preference

  10. Market Value and Industry Rating Tools • Valuers understanding and knowledge of rating tools • Australia ahead of NZ – result of industry awareness and tool development • Uncertainty of the impact of rating tools– lack of evidence and research • Varying opinions on which tool has the most beneficial impact on value

  11. Impact of Rating Tools on value

  12. Industry rating tools & value

  13. Conclusions & Further Research • Confusion and lack of knowledge • Inability to compare all building upon a single rating system – both performance & holistic • If Valuers reflect the investor market – when the two are placing value on two different elements – how can value be quantified? • For the ‘value of sustainability’ to be identified more work needs to be undertaken to be able to identify, quantify and measure the level of sustainability across ALL buildings - New and Existing buildings!!!!!! Then the value connection can be examined.
