Green Buildings – Why? The problem – carbon and climate change? The opportunity – economic & environmental benefits The solutions – – Renewable energy – Carbon management – Energy management – Sustainable construction and “green” buildings
Carbon and Climate Change Buildings account for approximately 40% of raw material and energy consumption 55% of wood not used in fuel production is consumed in construction Buildings and associated construction activity account for at least 30% of global greenhouse emissions Energy represents 30% of operating costs in a typical building (Kok, N. 2009. Corporate Governance and sustainability in global property markets)
BREEAM EuropeWhat is BREEAM?•Environmental Assessment Method for new Buildings•Certification scheme•Voluntary•Independent & credible•Holistic•Customer focused•Credits basedImprove the Environmental Performance of the Building;Improve the Internal Environment for Occupants;Improve upon existing environmental standards.Types of building covered by BREEAM International:Retail, Offices and associated areas, Industrial, Toyota retail units,More to come…
Aims of BREEAM:To mitigate the impacts of buildings on the environmentTo enable buildings to be recognized according to their environmentalbenefits To provide a credible, environmental label for buildings To stimulate demand for sustainable buildingsObjectives of BREEAM: To provide market recognition to low environmental impact buildingsTo ensure best environmental practice is incorporated in buildings To set criteria and standards surpassing those required by regulationsand challenge themarket to provide innovative solutions that minimize the environmentalimpact of buildingsTo raise the awareness of owners, occupants, designers and operatorsof the benefits ofbuildings with a reduced impact on the environmentTo allow organizations to demonstrate progress towards corporateenvironmental objectives
A number of GBCs are also looking at adapting BREEAM into their own national environmental assessment methodLeading to a tool that is: Nationally recognised and endorsed Appropriate and tailored to the local context and conditions Consistent with other international standards and assessment tools Available in the local languageAdvantages: Benefiting from BRE’s knowledge and expertise Best practice sharing Less resources required Income revenue
Stages of AssessmentThe stages of assessment in which the BREEAMschemes can currently be used to assess the environmentalimpacts arising as a result of an individual buildingdevelopment (including external site areas) are:•Design Stage•Post Construction Stage (mandatory in allschemes from 2009 Autumn)•Operational Stage (BREEAM in Use indevelopment for International)

BREEAM vs LEED vs Green Star etc. LEED over simplifies the use life cycle analysis, in particular relating to building materials Green star – issues associated with spanning differing climatic zones. (Cooling tower credit) Green star awards credits for issues such as mould prevention, low VOC finishes, and avoidance of composite wood product. BREEAM International – localised framework but still developing. Previous issue relating to design stage & construction stage certifications now resolved.
BREEAM vs LEED vs Green Star etc. Overall Rating comparison Source: BREEAM 2009
Questions to ask yourself Where is the building being constructed? Who is the intended occupant/buyer? Does the building type meet any of the generic schemes? Which scheme will provide the highest rating for your development? Does your design team have familiarity with one particular scheme or all? Are there any local assessors available for each scheme? Are country reference sheets complete?
General information One part of a raft of measures contained within the Energy Performance of Buildings Directive 2002/91/EC including: – Thermal rehabilitation of existing building stock – Inspection of air-conditioning systems – Certification of independent experts Norms and calculation design criteria for the energy performance of a building stipulated in law nos. 372/2005 and 157/2007.
Requirements Requirement for an EPC on construction sale or rental of a property from 1st January 2007, however deferred to 1st January 2010 in Romania and Bulgaria. Must show the assessment rating Expressed on an A-G scale (and numerical) Must not be more than 10 years old Decreasing exceptions Provide recommendation for improvement Public buildings require a Display Energy Certificate.
Interaction with BREEAM Energy assessment in BREEAM allows up to 15 credits when the assessed building demonstrates an improvement in the energy efficiency of the building fabric and building services Energy performance is shown as a CO2 based index The credit scoring is determined by comparing the building’s CO2 index taken from the EPC with CO2 emissions from a reference building
Green Buildings – theeconomic case Neil Foster – WSP Group SRL
Current & Future Economic Drivers Increased analyst and investor screening of corporate environmental and social policies (CSR) including real estate investments Increasing certainty of the business case for developing green The continual increase of energy prices Increased competition through tougher market conditions. The need for developers to remain competitive. The opportunity to be seen as a market leader through seeing green building as a unique selling point
Evaluating Energy Efficiency In normal times: Green rated buildings commanded rental rates roughly 3% higher per square foot than otherwise identical buildings Premiums in expected rents (i.e. rents adjusted for building occupancy levels) are even higher – above 6% Selling prices up to 7% higher
Productivity Benefits Offices – 2-16% productivity increase Retail – increase in sales per sq foot Schools – 10-15% betterment in results
Evaluating Energy Efficiency In the current market: Blue-chip investors and tenants remain active in the market and are therefore most attractive to developers. Green rated buildings have a greater likelihood or occupancy or sale Investors are seeking pre-let or leased buildings with guaranteed returns Lower ongoing running costs for developers working on a BOT (build-operate-transfer) basis.
Construction Costs The earlier in project planning green methods are considered the lower the likely impact upon final construction costs. Green rating/schemes are designed to recognise good design not to force it upon developers and designers. Certification costs are small in comparison to design costs <5% excepting smaller buildings/developments
