2Contents What makes a sustainable building? Credit examples BREEAM aimsHow BREEAM worksBREEAM growthWelcome to BREEAM Offices half day seminar.Today we are going to take you through:Details of what BREEAM is and it’s aims.We will then go through a workshop which will allow you to understand the technical issues that BREEAM addresses within the schemeThis will give you more of an understanding to carry out a Pre Assessment Estimator exercise – which is a simplified pre BREEAM assessmentWe will then take you through some aspects of the assessment process – fees, statistics of number of assessors, costs of assessments and how to achieve a higher BREEAM rating.We are often asked what are the increase in captial costs to build a sustainable building and we will take you through a piece of research we carried out looking at offices, a house and PFI health centre.Finally we will go through an exemplar school case study highlighting some of the issues that BREEAM awards credits.

17Environmental Weightings BREEAM - WeightingsManagementHealth & W’beingEnergyTransportWaterMaterialsLand UseEcologyPollution1525510Environmental WeightingsEach section has a weighting factor applied to it. These were derived through consensus based research with a number of different groups and organisations – government bodies, manufacturers, green lobbyists etc. This gives it a sense of importance to each issue – therefore you can see Energy and Transport were considered the most important issues because of the CO2 implications associated with them. At the time water wasn’t considered as important however today we are constantly provided with information to the contrary – droughts and floods appear to be a major problem within the UK. In line with the update of the GREEN Guide to Specification this exercise will be carried out again to establish the current importance of each issue.
18What is BREEAM? Environmental Assessment Method Certification scheme VoluntaryIndependent & credibleHolisticCustomer focussedCredits basedBREEAM is the Building Research Establishments Environmental Assessment Method.It is a certification scheme, therefore once an assessment has been carried out and passed our quality assurance process a certificate is issued. We have now achieved compliance with UKAS and ISO9001, we will go through more information on this later.The scheme is voluntary, however more organisations and government bodies are specifying BREEAM as with English Partnerships, Housing Association, DfES (we will talk more about this later) and soon possibly Code for Sustainable Homes.The scheme is independent in that we train assessors who then purchase a license to carry out assessments on behalf of BRE. We ensure it is credible by consulting with various technical experts, our assessors and an independent sustainability board.The assessment is holistic, it addresses a number of issues on the sustainability agenda, not just energy and carries weightings associated with the importance – we will go into more detail about this later.The scheme is customer focused – assessors provide feedback to us from the industry on how to improve the scheme and what direction it should take.The assessment is a credits based system.
19Aims Improve environmental performance of buildings Improve internal environment for occupantsWithin BREEAM we are aiming to improve the overall environmental performance of buildings – in terms of energy, embodied energy, pollution, water etc.However it is important to understand that the occupants using the building enjoy using the space and perform well within it – it is all very well having an environmentally efficient building but it needs to be well daylight, ventilated and thermally comfortable etc.
20Mass market Number of buildings BREEAM Environmental Standards Regulatory minimumMinimalBREEAMAspirationalThis diagram gives an indication as to what BREEAM is trying to do with buildings in terms of environmental benchmarks.We have the number of buildings on the Y axis and the environmental standards on the X axis. As we can see they are continually being pushed. Environmental standards are increasing with Building Regulations which is the regulatory minimum and as we can see from the diagram the number of buildings being built are only just achieving this level. What BREEAM is trying to do is move the mass market, the majority of buildings, towards achieving more sustainable and efficient buildings – rather than focus on improving the minority exemplar buildings.Environmental Standards

27Annual review process Each scheme is reviewed annually Currently ‘2006’ versionReview process driversBuilding RegulationsChange in legislationIndustry best practiceChange in common practiceTherefore a 2006 VERY GOOD is a higher standard than a 2005 VERY GOOD rating.
28Cost of sustainability ‘Putting a price on sustainability’ BRE Trust (BRE & Cyril Sweett), 2005Covers :HousingNaturally ventilated officeAir conditioned officePFI health centreCapital cost implications of achieving the different BREEAM / EcoHomes ratingsAvailable from BRE bookshop £9 / £22.50
29Results – worst case scenarios % Increase in capital cost to achieve a BREEAM rating:LocationPassGoodVery GoodExcellentPoorupto 0.1%upto 0.9%upto 5.7%-Typical0%upto 0.4%upto 1.7%upto7%upto 1.3%upto 4.2%This study looked at the worst case scenario for each location.Compared three locations: poor-bad transport links and greenfield site – achieve no transport and LU&E credits, typical scored some and Good location scored all site specific credits.As we can see the increase in capital costs in a poor location is up to 5.7% to achieve a Very Good rating. Therefore you can still achieve the requirements set by DfES in a worst case location for small extra costs. Excellent couldn’t be costed as this included credits that were site specific and could not be allocated a general cost such as recycled aggregate.Why did DfES not ask for Excellent?Because there was no increase to the allowed cost per square metre for new schools, that BRE advised DfES to require a “VERY GOOD” rating rather than the “EXCELLENT” standard set by the OGC. From the schools used to pilot BREEAM Schools it was felt that achieving a “VERY GOOD” rating would be possible within the current budget constraints of £1050/m2. It was also felt that this would allow schools such as St Francis of Assisi (with a sustainability specialism) to demonstrate their environmental credentials by exceeding the required minimum level of “VERY GOOD”.BUT It is worth noting the earlier in the design process that BREEAM is considered, the easier and cheaper it will be to get a higher BREEAM rating and therefore achieve an Excellent rating and a more sustainable school.‘Putting a price on sustainability’
31BREEAM Awards Response to request from assessors and clients Presented at BRE annual conferenceAwards in each schemeHighest performing buildingWe’ve also introduced the BREEAM awards this year. This is partly in response to the comment that there is no incentive for people to go just beyond the 70% for an excellent rating, but also to raise the BREEAM profile, and also the profile of high performing buildings. Thereby demonstrating and rewarding excellence.There are awards in each BREEAM version, and they are simply awarded based on the highest BREEAM score. The awards will be presented annually at the BRE conference and you can see last years winners in the photograph here, (a couple of the winners are also shown on the next slide.)
32Offices Winner - Scottish National Heritage HQ OverviewOccupant control for lighting, heating and ventilationProximity detection for the water supply to all urinals and WCsEnhancement of the ecological value of the siteExtensive use of FSC certified timberRe-use of a site that was previously contaminatedThese are two of the winners
