1. Introduction

This Sustainability and Energy Statement has been prepared to discharge Condition 15 for the proposed application for up to 300 new homes at Bitham Park, Westbury.

Introduction Proposed Development

This Sustainability and Energy Statement has been Located on the Northern edge of Westbury the prepared to discharge Condition 15 of the approved development site covers approximately 11.2 hectares and application (APP/Y3940/W/15/3130433) for the comprises of up to 300 new homes including a new development of up to 300 new dwellings including open roundabout for access and areas of open space. space, landscaping and the associated access at Bitham Park, Westbury in Wiltshire.

Condition 15 states – The dwellings hereby approved shall achieve a level of energy performance at or equivalent to Level 4 of the Code for Sustainable Homes. No dwelling shall be occupied until evidence has been issued an submitted to, and approved in writing by, the local planning authority certifying that this level or equivalent has been achieved.

In this context, the following sections of this sustainability and energy statement set out the measures incorporated into the design of the development masterplan and individual homes which contribute towards the delivery of sustainable, low carbon homes as well as responding positively to the requirements of Condition 15.

This section of the report provides an overview of the relevant planning policy and guidance regarding the development of low carbon new dwellings from a national and local perspective.

The proposed dwellings have been designed in accordance with the ‘energy hierarchy’, which aims to reduce energy demand through passive design measures and a fabric first approach before utilising low carbon energy and the production of on-site renewable energy.

Energy Strategy Summary

In summary, the proposed dwellings will be designed in accordance with the principles of the energy hierarchy to include measures to reduce the primary energy use and carbon emissions which aim to go beyond the requirements of the latest Building Regulations (2013) through the use of WWHR as a low carbon technology.

Table 3 below demonstrates how the proposed specification of new homes is estimated to exceed the requirements of the 2013 Building Regulations.

• Specification of design to use offsite pre-fabrication with production of materials in low waste environments.

These measures will help reduce primary resource use and reduce waste from the manufacture of materials and the overall development design.

Construction Waste Management – Prior to the construction phase an appropriate Construction Environmental Management Plan (CEMP), or equivalent, will be developed to ensure the use of measures to minimise waste during the construction phases of the development, including measures such as:

 The supervision of deliveries and secure storage of materials to minimise on-site damage;

 Where possible, the use of a scheme for recycling and reusing materials on site;

 Minimisation of the excavation and landscaping requirements of the proposed development by making best us of the site topography;

 Monitoring of resource use, reviewing energy and water use and putting in place measures to minimise resource use during construction;

 Monitoring of construction material with waste stored in a dedicated storage areas; and

 Storage and labelling of construction waste in dedicated skips to ensure collection and storage of common waste streams to facilitate reuse and recycling.

In addition the development will be registered with the Considerate Constructors Scheme (CCS) and achieve certification against the Code of Considerate Practice.

Operational Waste Management – To encourage residents recycling the new homes will be provided with suitable external space for the storage of both non- recyclable waste and recyclable waste outside. Dedicated storage spaces for waste within new homes, including food waste to encourage residents to recycle waste materials will also be provided.

Full consideration will be given to the Council’s waste management infrastructure and services to ensure that the occupiers have the necessary infrastructure to participate in any kerbside recycling services.

Barratt Homes is committed to the delivery of energy efficient low carbon homes which provide long term environmental benefits.
