2008 AWARD WINNERS BREEAM (Building Research Establishment Environmental Assessment Method) is the world’s leading environmental assessment method for buildings, with over 110,000 buildings certified and over half a million registered. It sets the standard for best practice in sustainable design and has become the de facto measure of a building’s environmental performance. Credits are awarded in each of eight categories according to performance. These credits are then added together to produce a single overall score on a scale of: PASS, GOOD, VERY GOOD, EXCELLENT. www.breeam.org 2008 BREEAM AWARDS BREEAM 2008 came into force on August 1st 2008. One of the main changes included creating a new rating – BREEAM Outstanding – that will sit above the Excellent rating. For the third year running BRE Global will be presenting awards for the most environmentally friendly buildings certified by BREEAM. The BREEAM Awards recognise and reward those involved in the design and construction of the highest scoring buildings certified under BREEAM that year. A BREEAM ‘EXCELLENT’ rating is a pre-qualification, so the winners truly represent the UK’s top examples of sustainable design. In order to win an award, each building must have excelled in every environmental category within BREEAM (e.g. from Energy to Ecology) and therefore winners represent a holistic approach to delivering environmental sustainability. As with all BREEAM-rated buildings, the award-winning designs have been independently assessed and certified. The 2008 awards will be given to buildings in the following categories: • BREEAM Bespoke • BREEAM Fit Out • BREEAM Industrial • BREEAM Multi-Residential • BREEAM Offices • BREEAM Retail • BREEAM Schools • Code for Sustainable Homes For further information regarding BREEAM please visit www.breeam.org 2008 This c ertific ate is BREE prese nted AM A WAR DS to THE M UNIV ATTHEW ERSIT H Y OF AY BUILD ABER IN DEEN G, Winn , ABE er of the 2 RDE 0 08 B R E EA EN M Aw ard C atego ry: B REEA M BE SP Clien t: Archit ect: OKE Unive rs Benn ity of Ab etts A e ssocia rdeen tes The M atthe w Ha y Buil BREE ding AM (B achie is the uildin ved a w score practi orld’s le g Researc of 76 ading h Esta ce in .19% build ing’s sustainab environm blishmen t ental le de envir sign onme asses Environm a en ntal p n s erform d has bec ment.

The Matthew Hay Project is to be the final part in his vision. • • Developed through a strong collaboration between NHS Grampian and the University of Aberdeen, the Matthew Hay Building will combine teaching accommodation for undergraduate and postgraduate students and healthcare professionals in a single building. • • All insulants were specified with low Ozone Depleting Potential (ODP) and Global Warming Potential (GWP) Encourage use of public transport All BREEAM construction site impacts considered and achieved Low water consumption fittings Rainwater harvesting system. The BREEAM Assessment The University of Aberdeen understands the need for sustainable development and has taken the opportunity to incorporate exemplar BREEAM targets into the design and procurement process. The Matthew Hay Building is the first to go through this process and, through close work with the design team and the BREEAM Assessor, the University of Aberdeen was delighted to achieve the BREEAM Excellent rating. The development has achieved a BREEAM Excellent rating, scoring 76.19%. As a university facility the building fell outside the standard BREEAM schemes and a Bespoke BREEAM Assessment was necessary – this is where the criteria are specifically tailored to the building type. Overall the sites have performed very well, gaining full credits for the Management section and achieving high scores in the following areas: • Health & Wellbeing • Energy • Transport Key Facts Building Services • • • • • The building is serviced by a low temperature hot water (LTHW) system which provides hot water to serve perimeter heating, natural ventilation and mechanical ventilation systems. BREEAM Rating: Excellent Score: 76.19% Size: Net lettable area – 3,310m2 Stage: Design & Procurement BREEAM Version: 2005 Overview of Environmental features The Matthew Hay Building benefits from: • A highly efficient façade system. • U-values and air permeability beyond the minimum requirements of Building Regulations. • Exposed, reinforced concrete frame • Natural daylighting • Local controls for heating and lighting • A Building Management System (BMS) • Day and night lighting modes • Monitoring of all plant items and energy consumption • Mixed mode ventilation strategy • Majority of spaces being naturally ventilated • Low carbon technologies and passive renewables • Heating source with low NOx emissions • Green Guide-rated materials Extensive thermal modelling was undertaken to assess the building performance, leading to accurately sized and efficient plant. The façade is also highly insulated which adds to the thermal mass and reduces heat loss. The mechanical ventilation system incorporates high efficiency thermal wheels. The thermal wheels remove heat from the exhaust air which would normally be rejected to the atmosphere and it transfers it to the supply Green Strategy • • Pollution Materials & Waste Water Land use & Ecology Health & Wellbeing 60 • What have you learnt about BREEAM? The BREEAM process is continuing to develop, especially with the new version of BREEAM 2008, which allows design teams and developers to be challenged within their designs. Achieving BREEAM Excellent on the Matthew Hay Building was attained through close collaboration between the design team and the client to realise the sustainability objectives set out in BREEAM and the targets set by the BREEAM Assessor.

Design Team details Management 20 A rainwater harvesting system has been installed which collects rainwater and uses it to serve the WCs. This item of plant reduces carbon involved in mains supply provision and reduces the demand for potable water supplies. • The external façade utilises fixed louvres and exposed concrete ceilings to increase the thermal inertia of the building. This has allowed the use of natural ventilation to perimeter rooms negating the need for mechanical cooling and ventilation. Percentage % of score attained 0 air (when required) thereby pre-conditioning the air in Autumn and Winter periods. These significantly reduce the boiler demand of the central plant. 80 100 “BREEAM challenges the Design Team to provide not only sustainable designs but also innovative concepts to such designs. From a personal point of view, this is an exciting proposal to be involved in. From a wider perspective it can only be advantageous to the environment as a whole, as well as providing the end user with an excellent working environment with low environmental impact.” Debbie Butler, University of Aberdeen 2 I BREEAM 2008 AWARDS BREEAM Fit Out Award Winner: 16 Noel Street, London about the building The BREEAM Assessment Design Team details Morgan Lovell has offices located in London, Birmingham and the Thames Valley, and is a office interior design, fit out, refurbishment and relocation specialist. The development achieved a BREEAM rating of EXCELLENT, achieving a score of 76.22%. The buildings achieved full credits in both the Management and Land Use & Ecology category and gained high scores in the following categories: • Water • Materials • Health & Wellbeing Architect: Morgan Lovell Developer: Morgan Lovell Client: Morgan Lovell BREEAM Assessors: Diligentia Ltd Its in-house teams of designers, surveyors and project managers can design and deliver entire projects, with the benefit of just one point of contact, whether a company is relocating or refurbishing, or both. Morgan Lovell employs 120 people. This year it was named in the Sunday Times Best Green Companies. It is also a FTSE4 Good listed organisation and holds the environmental standard ISO 14001 and is a member of the UK Green Building Council. Morgan Lovell specialises in the design and build of sustainable offices and wanted to use the scheduled fit out of its own office as a pilot scheme to develop a BREEAM ‘Excellent’ rated development in a 1960s office block - the type of building that would normally be viewed as an environmental write-off. The office covers two storeys of a multi-tenanted, six-storey office block.

Building Services Initial reports show that 16 Noel Street is cutting energy use by around 11 per cent, compared to usage prior to the fit out. What have you learnt about BREEAM? The BREEAM process has allowed us to learn the benefits it can bring to energy efficiency and staff health and wellbeing in particular. It has enabled us to influence and guide clients on their own BREEAM fit outs with at least three other schemes successfully implemented in the last six months alone. This saving comes from three key areas: • The use of efficient new plant • Heating and ventilation (zoned) • Intelligent lighting (with features including sensors, zoned areas and dimmers that automatically adjust to natural lighting conditions) The M&E system is state-of-the-art and harnesses any heat rejected in areas being cooled, and uses it to warm up other parts of the building as required. Each floor is separately metered to closely monitor energy usage, as is the air conditioning energy use. Green Strategy Environmental fixtures and fittings - From recycled plastic bottles for kitchen surfaces, recycled car tyres for entrance mats, FSC timber and clay based paint to cut VOCs, the specification process involved the careful sourcing of products for minimum impact on the environment. Everything was considered for its high grade of recycled and recyclable content. Waste Management - At the construction stage, waste was carefully segregated and taken to licensed stations. Existing chairs and the reception desk were reused and other furniture and items including computer equipment that were not needed were given to charities for reuse. Recycling - Full recycling stations are built-in at strategic locations across the office.

The commitment of Lancaster University and UPP to environmental issues required that this latest phase of student accommodation should focus on sustainability and improving environmental performance. BREEAM certification was a requirement of Lancaster University. • • • • • • • • • High levels of insulation High levels of airtightness Mechanical heat recovery ventilation systems Low NOx, A-rated gas condensing boilers Solar water heating Building management system Low water use aerated taps and showers, dual flush WCs SUDS (Sustainable drainage) wastewater attenuation system Full low energy lighting/PIR to common areas High levels of acoustic performance Dimensioning to accommodate standard building material sizes Simple plan configuration Use of A-rated Green Guide products FSC-certified timber Ecologist’s recommendations implemented Recycling storage space. Building Services Key Facts The overriding approach has been to reduce energy loads by passive means, significantly improving insulation values and airtightness performance to the accommodation. Both the townhouse and cluster flat accommodation are provided with low pressure hot water heating using low NOx, A-rated gas condensing boilers. High levels of insulation and excellent airtightness performance have reduced space heating requirements and the largest energy load is providing hot water. • • • • • Whole house mechanical heat recovery ventilation units are used to deliver fresh, filtered air to all habitable rooms, with 80% heat recovery efficiency. Solar thermal collectors are used on cluster flat accommodation to pre-heat water. The new accommodation at Lancaster University is seen as part of the educational offering, and incorporates many of the attributes that support sustainable student living. BREEAM Rating: EXCELLENT Score 71.4% Net lettable area: 9240m2 Stage: Design & Procurement BREEAM Version: 2006. The BREEAM Assessment The development has achieved a BREEAM Excellent rating scoring 71.4%. Overall the scheme performed very well gaining maximum credits within the Management section and achieving high scores in the following areas: • Health & Wellbeing • Transport • Land Use & Ecology • Pollution The scheme also achieved a significant proportion of the energy credits due to the high energy standards achieved. Building Regulations, and the high levels of airtightness encouraged the use of mechanical heat recovery and ventilation systems to provide a controlled, filtered whole house ventilation system. A variety of measures have been adopted to ensure a healthy internal environment, in particular quality of indoor air, levels of natural light and improved acoustic performance. Wherever possible natural and benign materials and finishes are used internally, care being taken to avoid materials which omit unwanted VOCs. All paint finishes are based on natural technologies and solvent free. Traditional solvent-based adhesives/sealants are avoided. The use of controlled ventilation with heat recovery ensures a continuous supply of fresh air to all habitable rooms, and helps maintain optimum humidity levels in the accommodation. The townhouses are designed so that only the party walls are load bearing with floors spanning between these walls. This allows the internal space to be flexible in respect of layout and may be reconfigured if necessary, future proofing the accommodation. Aerated taps and showers deliver controlled amounts of water, and dual flush WCs are used throughout. Design Team details Metering of utilities is discrete to each townhouse enabling each dwelling to review and compare actual usage online. The University is implementing an incentive scheme to promote responsible utility usage. University Client: Lancaster University Developer Client: UPP Ltd Architect: Goddard Wybor Practice M&E Consultants: Bailey Gomm Principal Contractor: Norwest Holst Green Strategy What have you learnt about BREEAM? Attention has been given to the construction process and waste generation during construction. We have found the discipline of undertaking the BREEAM assessment to be helpful to the project delivery team and not difficult to satisfy given the background and approach to the student residential concept, which is based on sustainable principles. The building incorporates significantly higher levels of insulation and airtightness than required by current Percentage % of score attained Management “The generally accepted definition of sustainable development places upon us an approach to development whereby every action has to be taken while considering its future effect.

Situated in Alnwick, in the North East of England, it is a flagship development designed to achieve exemplary standards of sustainability and environmental performance. The new office building is formed of two blocks located to the south and east of an existing building which remained fully operation during construction. The development has achieved a BREEAM Excellent rating, scoring 80.72%. Overall the development performs well, despite the rural nature of the site limiting the number of credits which were achievable within the Transport section of the assessment. DEFRA champions Sustainable Development, helping Government as a whole to deliver economic, social and environmental sustainability. Defra is also the focal point for rural policy, supporting strong rural communities and ensuring that dispersed rural needs are reflected in social and place-based policies across Government. The Department has a strong international dimension, with a critical role in both European Union and global policy making. Within the energy credits the development also achieved all of the credits available for energy performance beyond the current Building Regulations. A number of specific targets were set for the project through a sustainability charter which all parties involved signed up to and was monitored throughout the design and construction process. These included: • Delivering a low carbon building and including wind turbines, photovoltaic cells, solar heating and a biomass woodchip boiler • Minimising mains water consumption through selection of low water use fittings and the use of a rainwater harvesting system with a consumption target below DEFRA’s own policy targets • Achieving a BREEAM Offices 2006 rating of Excellent and a score of at least 76%.

The design and construction teams were subsequently challenged to deliver the ‘Excellent’ rating. The scheme is the first retail project of its kind to achieve the highest BREEAM rating of ‘Excellent’. Top scores were achieved in the following categories: • • • Management 93.75% Health & Wellbeing 81.82% Transport 80% Building services Lighting: Lighting to streets is subtle and high efficacy LED lighting has been used where appropriate. Back of house area lighting is controlled by presence detectors to significantly reduce operational hours. Car park lighting energy usage costs will be halved through the use of intelligent controls and high-efficacy lamps and an enhanced level of control allows for a three stage switching of lighting to all decks, linked to daylight sensors to ensure lighting is not on during daylight hours. Perimeter lighting is also controlled independently. Ventilation: The architectural design of the scheme has taken advantage of natural ventilation to reduce the energy demands associated with heating and cooling via large air handling systems, saving around 5 million kilowatt hours per annum, equivalent to the energy consumed annually by 450 homes. Green Strategy Sustainability Guidelines: Environmental guidance for all tenants was provided through a number of initiatives including a shop-fit guide, retailer and on-site management training, and an education and green issues awareness programme. Materials: Building materials with low environmental impact have been specified for use throughout the scheme. Timber and insulation are environmentally sustainable, and recyclable materials such as zinc and copper have been used in preference to less recyclable materials. Materials such as natural stone, brick, steel, glass and landscaping have been predominantly UK-sourced where possible. Waste Recycling: During construction, 90% of steel waste was recycled, 80% of timber was chipped (recycled), and 40% of concrete was from recycled sources. Water: Low water use fittings have been installed in residential units, landlord and public areas. The rainwater harvesting system captures rainwater from the street canopies for re-use in flushing toilets and irrigation throughout the scheme.

The BREEAM Assessment method was used across all five schools for Greenwich BSF. It was instrumental in bringing a consistent level of high sustainability performance across a large building schools programme. BREEAM was effective in delivering sustainability through the common low energy and sustainable environmental engineering approaches by BDP that the process facilitated. The ‘Excellent’ rating was difficult to target, but ultimately proved achievable through the integrated design approach and inherent sustainable design from the outset of the project. Code for Sustainable Homes: 32 & 33 Tewitt Close, Windmill View, Illingworth Background Information Building Services These two homes in Illingworth are the first real homes to be certified against the Code for Sustainable Homes (Code) which was launched in April 2007. On all properties on the estate, as with other homes in the area, artificial stone was used to construct walls and dark grey concrete cladding used as roof tiles. All homes benefited from white UPVC double glazed windows, and a pre-finished composite door. These homes form part of the new 84-home Windmill View Estate in Illingworth, near Halifax. The estate includes 11 two-bed houses, 8 two-bed apartments, 2 one-bed apartments, 58 three, four and five-bedroom houses – all classic stone-fronted, spacious (and popular) properties. Twenty seven of these homes are available for shared ownership, with the remainder available for rent from Pennine Housing 2000. The development area had previously been used for a mix of social housing and high rise units but they were demolished, leaving the area as a waste ground in need of redevelopment. Instead of just building the scheme as planned, Bramall funded the Code assessment using the project as a test bed for the Code. The developers Bramall Construction specialise in the refurbishment and construction of public sector housing throughout Yorkshire, Humberside and the East Midlands. The company is part of Keepmoat plc, a leader in community generation in the north of England. Key Facts • • • • Code Rating: 4 Score: 70 No. of units assessed: 2 Stage: Post Construction Overview of Environmental Features: These first two Code houses have the following features: • Solar panels producing renewable energy for heating hot water • 44% improvement to standard building regulations • Improved U values on glazing, external doors and loft space • Fitted exhaust air heat pump • 300mm cavities which are fully filled to reduce energy loss • Recycling bins stored in the kitchen units • Improved sound insulation • Water-saving measures including low flush WCs and controlled flow rate taps • Home user guide • Use of Green Guide-rated materials • A Code for Sustainable Homes 4 Star rating • Full marks were achieved in three of the Code categories: −− Surface water run-off −− Waste −− Management • The two homes also scored well in the Water and Ecology categories. The homes contain solar panels which are used to heat inside and power the hot water systems. Exhaust heat pumps can top up the temperature by recycling warmer air from the kitchen and bathroom over a heat exchanger, converting it into fresh, filtered air. The solar panels and heat pumps contribute to a 44% improvement on Part L building regulations. The houses have thicker, 300mm cavity walls and improved insulation on the glazing, external doors, floors and loft space. They also use less water, through restrictors on taps and dual-flush toilets. The improved U values will mean residents will pay around 50% less for their energy bills. Green Strategy Both homes met the Code requirements in specifying Green Guide-rated materials and all timber used is either PEFC or FSC certified. To reduce local traffic impact, homes are supplied with stores specifically made large enough to store bicycles securely.

From working on the scheme at Illingworth we have learnt that achieving the Code is not impossible but some of the individual areas that the company were scored on were difficult to achieve (eg ENE 1). However, the experience gained from the Illingworth scheme means that the next submission should be easier. THE eN Categ. . . Energ . Wa OR SUS TA .

We have a number of additional projects in the pipeline that will also be built to the Code. We fully support the work that Communities and Local Government are doing and hope to continue working with them’. Ashley Jones, Project Co-ordinator The estate also benefits from landscaping features. Each property has its own garden and private space with ample room for planting or for recreational use. The public areas have also been landscaped with trees and shrubs planted to create a pleasant view from the new houses. To ensure local facilities are further improved, a £50,000 donation has been given to Calderdale Council to carry out local improvements.
