“Green Value”Green buildings, growing assetsa new RICS international report

A Developer’s View

From

Jim Green MSc MRICS CES

Baylight Properties & RICS Presidential Commission on Sustainability


Statutory purpose what you must do l.jpg
Statutory Purpose – what you must do

  • Planning & Compulsory Purchase Act 2004

  • The statutory purpose of planning has now become the “achievement of sustainable development”

  • Pension Funds Disclosure Regulations – must publicly reveal ethical & environmental stance and commit to future improvement

  • EU Green Paper 2001 – Euro framework for accounting standards committing institutions & companies to CSR & TBL


The majority of property developers see green buildings l.jpg
The majority of property developers see Green Buildings

  • “as an interesting but questionable concept that they may have to engage with to obtain planning permission and which is likely to both increase their costs and reduce their profits”

  • Not sufficiently profitable – not sustainable

  • Are they the New Luddites ?

  • Still holding on to old technology – younger generation thinks differently



Green value study l.jpg
Green Value Study

  • RICS- Worlds largest real estate profession. 117,000 members in 123 countries

  • Professional qualifications FRICS, MRICS, CES

  • Agenda for Change 2000 – 16 Faculties inc Environment

  • Resources - Over 400 publications published annually

  • Green Value Report

  • Commissioned to develop better understanding of the linkages between Green Buildings and Value to various stakeholders

  • Green Value Case Studies

  • 18 project reviews including 3 Universities featured today

  • www.rics.org/greenvalue Exec Summary / Report / Case Studies / GreenBuild Conference Atlanta Nov 2005


Green value key barriers l.jpg

Assumption that it costs more to build green

Knowledge and research not widespread

Green options are poorly understood

Steep learning curves

Construction companies lack experience

Not seen as business benefit

Shortage of professionals with suitable experience

Insufficient understanding of value and appraisal

Outdated regulations

Perception of risk amongst lenders, funders

Green Value – Key Barriers


Green value report conclusions 1 l.jpg
Green Value Report – Conclusions 1

  • Cost does not equal value

  • Value may exceed cost savings many times – focus on value as well as costs

  • Value is hard to define; many benefits unquantifiable but undeniable – especially productivity

  • Distribution of costs and benefits of green buildings varies significantly – occupiers gain

  • Number of green buildings is small but growing- we are all learning, evidence base needs to grow


Productivity gains l.jpg
Productivity Gains

  • Adding skylighting to retail store increased productivity 40% (Heschong Mahone Gp)

  • Conversion energy savings gave payback 4.1 yrs / ROI 24% but benefits from lower absenteeism and productivity payback 69 days / ROI 540% (Penn. Power & Light)

  • CABE “Value of Good Design” - hospital eco renovation gave 21% improvement in discharge rates, care quality, speed, satisfaction, less drugs, reduced visits


Green value conclusions 2 soft benefits value l.jpg
Green Value: Conclusions 2Soft Benefits (Value)

  • 85% of a buildings real costs are related to staff/productivity costs – user satisfaction is therefore key

  • Initial construction costs <10% of a buildings life time costs

  • Energy is typically 30% of a buildings operating costs

  • Increased productivity especially through daylighting

  • Enhanced health and well-being

  • Higher academic achievement

  • Higher morale

  • Reduced absenteeism

  • Image – branding and symbolising values

  • More data needed to audit and provide reliable evidence for these


Green value conclusions 3 l.jpg
Green Value – Conclusions 3

  • Limited post-occupancy feedback limits evidence

  • Strong ties exist between green building and marketing profiles

  • Regulatory and financial barriers still exist

  • Cost and time of Certification (LEED/BREEAM) is a disincentive

  • Importance of integrated design processes / chain of procurement client-led

  • Positive impact on communities



Case study 1 c k choi building university of british columbia13 l.jpg
Case Study 1: C.K Choi Building, University of British Columbia

  • Institute of Asian Research

  • Completed October 1996, @2,788 sq m (gross), owner occupied

  • 5 research centres, conference facilities, FT occupancy 100 people / capacity 150

  • Construction costs ($1578/sq m or £147 psf); total @ $4.4M

  • $44,000 grant to enhance energy efficiency; private donations 50%


Choi building design features l.jpg
Choi Building: Design Features Columbia

  • Tree stands to reduce cooling loads

  • Internal stack effects (natural ventilation)

  • Building forms to enhance day-lighting thereby reducing lighting and cooling loads

  • Enhanced energy control systems

  • Waste heat recovery

  • Composting (waterless) toilets

  • Rainwater harvesting and Greywater collection for irrigation (no sewer connection required)

  • Zero ozone depleting substances, low solvent, low VOC material specifications


Choi building project successes l.jpg
Choi Building: Project Successes Columbia

  • Same construction cost as conventional building

  • 69% reduction in elec. usage compared to ASHRAE standards, saving 191,000 KwH per annum

  • High recycled content in building materials

  • 60% primary wood structure

  • 100% exterior brick cladding

  • Positive impact on enrolment and University reputation

  • Learning points: Would have installed a ground source heat pump; natural ventilation is not always easy to manage / better acoustic treatment needed for naturally ventilated areas



Case study 2 liu centre university of british columbia17 l.jpg
Case Study 2: Liu Centre, University of British Columbia Columbia

  • Completed Sept 2000, 1747 sq m

  • Teaching and office areas and public spaces for events, conferences

Implications for uk heis l.jpg
Implications for UK HEis Columbia

Well designed and implemented buildings can deliver:

  • Reduced whole life costs

  • Better functionality for users including those who have to maintain

  • Involving and understanding user requirements and experiences is central to Green Building Design – often neglected to a significant cost

    The Green Building movement is getting a critical mass

  • Especially in North America

  • Including many US universities


Implications for uk heis25 l.jpg
Implications for UK HEis Columbia

Green Buildings are moving up the experience curve

  • Better understanding of what works, and doesn’t

  • Falling costs for key technologies

    Green building is inevitable

  • To respond to climate change and stricter regulation

  • To improve long term financial and market performance of HEis
