2008 AWARD winners for wales

Transcription

1 2008 AWARD winners for wales BREEAM (Building Research Establishment Environmental Assessment Method) is the world s leading environmental assessment method for buildings (with over 100,000 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. The operation of BREEAM is overseen by an independent Sustainability Board, representing a wide cross-section of construction industry stakeholders. BRE Global will be presenting an award for the most environmentally friendly buildings in Wales certified in 2007 by BREEAM. The BREEAM awards for Wales have been created to recognise and reward those involved in the design and construction of the highest scoring buildings certified under BREEAM in Wales that year. A BREEAM EXCELLENT rating is a prequalification, so the winners truly represent Wales top examples of sustainable design. Unlike many construction awards, the BREEAM awards are not subjectively judged but reward the developments that have been independently assessed and certified as scoring the highest number of credits in the relevant year and location. The prerequirements are that the development must score an EXCELLENT and have been certified to a recent BREEAM version (2005 onwards). The 2008 BREEAM AWARDS for Wales will be given to buildings in the following categories: 2006 BREEAM AwARds This certificate is presented to ThE Mills Building VETERinARy laboratories AgEncy, weybridge Winner of the 2006 BREEAM Award Category: BREEAM Bespoke 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.

4 BUILDING SERVICES Excellent U-Values (i.e. well insulated fabric) have been achieved through construction techniques and materials improving the thermal performance of these homes resulting in a 35% improvement on 2002 Part L requirements. GREEN STRATEGY The homes at Glasdir scored high marks in the Transport category through the provision of cycle storage for residents and have managed to gain the two credits available for public transport despite its rural location. DESIGN TEAM Developer: George Wimpey North West a Taylor Wimpey Company EcoHomes Assessor: Cyril Sweett Energy credits have been gained through an effort to minimise carbon emissions and improvements to the thermal performance of the homes. SAP calculations helped demonstrate this through improvements to: Air tightness Window U-values Full glazed doors External walls Roof U-values Ground floor U-values In the homes natural gases will be used for water and space heating and they will be serviced by class five energy efficient boilers. A-Rated fridges and freezers have been provided within all the homes, with the aim of reducing the release of ozone depleting (ODP) and global warming (GWP) substances into the atmosphere. Products which have zero ODP and GWP of less than 5 have been specified. These insulation products have been used within the; loft and wall cavity, flooring system, loft hatch and pipe work. Water efficient devices in all homes include: Flow regulated taps and showers Low flush toilets A-rated washing machines Local amenities are also within 1000m of the homes and all the homes meet the EcoHomes Home Office requirements. High scores were achieved in the section through the previously mentioned insulation materials. Light pollution has also been addressed as external lighting will be operated by PIR (Passive Infra Red) detectors. Renewable energy technologies have not been integrated in to the dwelling types. Consistent scores were gained in the Materials section through the use of a high percentage of PEFC and FSC certified timber. Green Guide A-Rated materials have also been used in the homes. The importance of recycling has been addressed through a recyclable materials collection system at the kerbside. Water consumption has been identified as an issue and water butts have been installed on rainwater pipes from the roofs of the homes to collect water for external use and irrigation of gardens. Percentage % of score attained Taylor Wimpey is focused on creating mixed and sustainable places to live featuring homes that are well designed, environmentally friendly and in locations that are well served in terms of local amenities. From our experience of having delivered high EcoHomes ratings (VERY GOOD and EXCELLENT) on a range of development types throughout the UK Taylor Wimpey uses the BREEAM EcoHomes scheme to assesses the performance of our houses as well as influencing the ongoing review of our designs and specifications. This research enables us to understand in detail the cost, design and other implications of seeking specific ratings at any given site. This development being the first EcoHomes EXCELLENT in Wales is a credit to the Company s commitment to sustainability and The Welsh BREEAM awards act as a valuable benchmark in this area and is tangible recognition that we are delivering against the most demanding objectives.

6 GREEN STRATEGY This office building nearly achieved full credits in the category by: Registering with the Considerate Constructors Scheme and scoring well Carrying out seasonal commissioning Supplying a building user guide Monitoring energy and water consumption on-site Committing to control waste on-site The development also performed well in the Materials section by only using FSC certified timber and incorporating local products which are Green Guide A-Rated including: Natural Welsh slate for the roof of the development Purpose made native hardwood from sustainable sources for the windows Lower brick plinth to external face, with timber frame and cladding with warm cell infill Internal wall is of plasterboard and plaster finish Concrete blocks to internal party walls, with plasterboard finish to reduce sound transmission from adjoining units. Additionally to prevent the unnecessary frequent replacement of carpets, under their tenancy agreement tenants will not be permitted to change carpets within the office for the first 5 years of occupancy. To address the need to recycle, a central storage space has been set aside to house four dedicated recycling storage bins. The location on which the business park is being developed has been reused as it formerly housed a Aluminium Die Cast unit. Remedial works carried out in advance of constructing the units contributed immensely to the ecological pollution by capping all wastes by the former thus preventing pollution off site at another source. The site has had a full ecology survey carried out and has been deemed to be of a low ecological value. Credits were gained in the category through the provision of permeable paving with 100% attenuation from rainwater runoff from hard surfaces. Additionally thermal insulation used in the building has a Global Warming Potential (GWP) of less than 5 and no refrigerants have been used. DESIGN TEAM Developer: The use of BREEAM Standards on our projects focuses the minds of both the client and design team members in providing facilities that meets the demands of current strategies and policies. BREEAM outlines the targets in which to provide a sustainable building unit for the benefit of occupiers. In this instance it also allows the new buildings to nestle in well with the established residential area nearby. This type of Development can also act as an attraction to the environmental conscious businesses such as N Power and Energy MGT.
