Promoting the Lessons of Sustainability
Our in-house Research and Sustainability Team work to assist in the enhanced design and construction of homes subject to the Code for Sustainable Homes and to deliver effective improvements in the efficiency of our core range of homes.
This focus encompasses: -
1. Improving the energy efficiency of the building envelope through:
- Enhanced thermal insulation.
- Low energy lighting designs
- Improving air tightness performance.
- Attention to junction detailing and thermal bridging potential.
The Standard Assessment Procedure (SAP) energy ratings for all homes are available for customers and are displayed in all completed properties, providing information on the running costs of a house.
2. On and off-site energy generation and carbon balancing:
New technologies are constantly under consideration for integration into our developments as part of an overall strategy involving best practice design and considered specification of materials.
Guidance is given to our companies on these aspects through the Redrow Renewable Energy Policy.
Technologies covered include: -
- Photo voltaics - Redrow are members of the WERC (Welsh Energy Research Centre) Photo voltaics task force.
- Grey water recycling
- Solar heating
- Water harvesting
- Heat recovery systems
- Off-site "green" energy generation
- Micro CHP
3. Water management:
- Incorporation of flow restrictors.
- Specification of dual flush toilets in all new homes.
- Incorporation of sustainable urban drainage systems (SUDS) where practicable as part of the development process.
- Creating wildlife habitats and lessening the impact of our developments on the environment.
- Incorporating water butts where practicable.
4. Consideration and trialling of new construction methods and products and processes:
- Seeking and trialling new materials and processes which are more efficient in performance, build and sustainability.
- Sourcing materials and products, ensuring that wherever possible, they are locally sourced and have been produced from sustainable or renewable resources.
- Design of housetypes which permit more efficient land usage by employing higher density development whilst still providing quality living environments.
Through our involvement with leading exponents in this increasingly science based field, such as the Building Research Establishment (BRE), the Home Builders Federation, the Welsh Energy Research Centre and NHBC we have shared our experiences to date of using the Standard Assessment Procedure (SAP) and the Code for Sustainable Homes (the Code), contributing to the continued development and evolution of the mechanisms underpinning the Code. For example, the data collected on-site during monitoring of designed energy performance versus actual measured performance at our Stamford Brook development, undertaken by Leeds Metropolitan University has been used as a basis for their LowCarb4Real workshop programme. This programme is designed to facilitate knowledge exchange, promote understanding of the application of construction technology, highlight key technical issues and thereby improve build quality and process and is being delivered to the industry at large.
‘Vision’ at Devonport, which is being developed in conjunction with English Partnerships, provides an example of how these our sustainability aspirations are being translated into reality.
This project is transforming the former M.O.D. South Yard stores enclave and provides 463 new homes and a range of employment, retail and mixed use development and includes a mix of homes built to BRE EcoHomes " Excellent " standard and Code for Sustainable Homes Level 3.
To date, this scheme has scooped the Sustainable Communities Award in the Royal Town Planning Institute Awards and a Commendation in the Housing Project of the Year category of the Mail on Sunday British Homes Awards, 2007 . The scheme is also shortlisted in a number of categories of the 2008 Housebuilding Innovation Awards, including the Regeneration Partnership Project and the Community Award.
We encourage our employees to be innovative and at Cheswick, another site delivering homes built to Code Level 3 of the Code, the Area Construction Manager and Site Manager have introduced energy saving features within the site compound together with rain water harvesting to supplement the compound’s water supply.
This year has also seen Redrow expand its in-house expertise with the addition of a qualified Code and EcoHomes assessment capability. Combining the practical lessons learned with these new skills has not only assisted us to deliver our first Code level 3 homes , constructed at Cheswick and Vision at Devonport, but has also guided improvements to our core housetype range.
Biodivesity
Biodiversity plans will become a feature of development as the Code becomes more widely adopted, however, Redrow already has experience of working with other stakeholders to provide the appropriate landscaping designs to encourage fauna and flora to flourish.
For instance Redrow has worked closely with Flintshire County Council, the Countryside Cou8ncil for Wales and local wildlife groups on its plans for 300 new homes on the site of the former Lane End Brickworks and quarry in Buckley, North Wales. A large part of this site is designated a Special Area of Conservation(SAC) and a Site of Special Scientific Interest (SSSI), primarily because it provides habitat for a colony of great crested newts, a European protected species.
Redrow’s proposals for the ecological restoration of the site involve creating a series of new newt ponds which will provide a greatly enhanced breeding habitat as well as areas of woodland and terrestrial habitat.
Although the site enjoys special protection because of the prescence of the great crested newts, Redrow’s wildlife mitigation plan for the site includes measures which will benefit a wide range of species, including birds, bats, badgers and amphibians.
Redrow has also prepared and is funding the implementation of an Ecological Management Plan to ensure sensitive long term management of the nature reserve.
Encouraging our Customers to think Green
We believe in encouraging our customers to appreciate that living on a new development brings benefits to the environment and to positively influence customers’ attitudes to more environmentally friendly living.
Additionally, we encourage our customers to reduce their own carbon footprint and live more sustainably.
We provide a comprehensive Homeuser guide tailored to each development informing the owner about the efficient running of their new home and local information on items such as public transport and recycling centres. We also integrate Travel Plans into the overall principles of development design where possible and our development at Farnborough encapsulates an example of this kind of Travel Plan which aims to increase the attractiveness of walking, cycling and public transport and to reduce the number of solo-occupied car trips.
Saving Water
Reducing water consumption in the home, at the office and on site is also seen as a priority.
Our standard specification aids our customers by including features such as dual flush WCs. Further water saving features such as restricted flow fittings and water butts are made available in our Green Options list. These items already come as standard in our Debut range and are of course included in homes we build in compliance with Code level 3.
Water conserving measures are also in use on site. At our Cheswick scheme rain water harvesting is employed to supplement water supply to the site compound.
