RICS Valuation Conference, November 2011 1Prof. Sarah Sayce BSc PhD FRICS IRRVKingston UniversityValuation & SustainabilityA Progress ReportThe Ambition• There is an undisputed desire to find the proof that ‘green’ or ‘sustainable’ buildings command a higher value (or others should be discounted?)Why?• we need to (must?) reduce energy/ carbon consumption• We wish to mitigate – in preference to adapt to –climate change• As a profession we have a belief in markets leading change – rather than rely on regulation  The current role of the valuer• The role of the valuer is primarily to reflect markets• They work on data and evidence• If there is a lack of evidence then the valuer cannot factor them in to their Market Values – but may need to advise on investment worth“When calculating a property’s worth, the market doesn’t currently take the issue of sustainability into account, but this could also have been said for central heating way back in the 1970s when people weren’t convinced it was going to have a market impact”.Ben Elder RICS Global Valuation Director, September 2011The theoretical positionSustainability Criteria metInvestment worth higher than market valueSustainability aware investor exploits mis-pricing to purchase or retain assetAs sustainability bites, asset performs better than market normMarket identifies mis-pricing and adjustsSustainability Criteria not metInvestment worth lower than market valueSustainability aware investor exploits mis-pricing to sell assetAs sustainability bites, asset performs worse than market normMarket identifies mis-pricing and adjustsWhy the pace needs to change• A lack of market response at the pace required:• Energy targets not being met• Challenges to create economic case to retro-fit stock – are they value efficient?• Inadequate reflection of the relationship between health and well-being and building stock• Difficulty in reflecting technological changes and the ratings appropriately into appraisals• Changing corporate  & societal environment • Changing client requirements and attitudes 6What is the opinion ?• Surveys have long shown that many people say they might pay up to 10% premium for LEED/BREEAM (CoreNet /JLL,2008)• But interviews show that whilst sustainability is desired, traditional selection criteria dominate (Dixon et al; 2009; Cushman & Wakefield (2011) “the trouble is that to calculate you need a sizeable benchmark and we don’t have that”Assessing the state of play• It is all about energy … where we have some metrics• Offices in US – clearly evidence to link energy certification (Energy Star) – some evidence re LEED  (Miller et al, 2007; Eicholtz et al, 2009; Fuerst & McAllister, 2011)• Offices in Australia: discounts for low scores; impact return, yield and vacancy of CBD offices (Building Better Returns (2011)Sayce et al. 2010Other Environmental Issues …• London is one of the most ‘at risk’ cities internationally due to the economic importance• Flood is as much about SUDS as coast of rivers• Research found that whilst taken into account on purchases it is not adequately accounted for subsequently • Too little recognition of impact of Flood & Water Management Act 2010• Flood risk insurance is a ‘live issue“it is important for valuers to understand how to articulate flood risk when pricing property investment assets even though evidence of a measurable effect on investment yields of on property rents is not readily apparent”CEM, 2011What is coming through …• Europe – less transaction based evidence of BREEAM/LEED – but starting … (Leopoldsberger et al. 2010)• Evidence from far east shows some  negativity (Deng li and Quigley 2011)• Investigations via Energy Rating Systems for Existing buildings: the new game in town (e.g. Dunse et al 2011)• Most work on multiple regression – and assume causality; still structural issues on ‘noise’• “despite the publicity and promotion, the voluntary certificated section is miniscule in terms of the current commercial real estate stock” (Fuerst & McAllister, 2011)• They are concentrated in new stock• EPCs may in some markets be important – but have acknowledged issues of accuracy and usefulness but are set to become criticalConclusions10Are certificates the answer?... • BSRIA: Soft Landings Framework Findings• Buildings do not necessarily perform to design belConclusions11Are certificates the answer?...
