Energy Impact Assessment/Statement
The 'Isle of Man Strategic Plan, 2007' states: Energy - Policy 5: 'The Department will prepare a Planning Policy Statement on Energy Efficiency. Pending the preparation and adoption of that PPS the Department will require proposals for more than 5 dwellings or 100 square metres of other development to be accompanied by an Energy Impact Assessment. ${ }^{(1)}$
The above Policy Statement is further defined with the following: 12.2.10 'In addition to alternative sources of energy supply, the Strategic Objectives in Chapter 3 refer to the promotion of efficiency and economy in the use of resources and the reduction of energy consumption by more efficient use of energy through energy conservation, recycling and waste reduction. There are numerous ways of increasing energy efficiency and reducing energy consumption both in the design and construction of new development and its subsequent operation, management and maintenance. The Building Regulations set standards for energy efficiency in new buildings including walls, windows, roofs and heating appliances. But the design and layout of new developments can in themselves reduce energy consumption through for example Passive Solar Estate Layouts. ${ }^{(2)}$ Added to this are the various solar panel, photovoltaic cell, solar energy and heat pump technologies. ${ }^{(1)}$ 12.2.11 'Within the Strategic Objectives relating to resource and to energy efficiency, the Department wishes to promote a greater awareness and recognition, of the benefits both to the environment and the consumer of energy efficiency in its widest sense. To this end the Department intends to prepare a Planning Policy Statement on Energy Efficiency. In the meantime it will require a planning application for more than 5 dwellings or commercial development of more than 100 square metres to be accompanied by an Energy Impact Statement ${ }^{(3)}$ to demonstrate what measures have been taken in the design of the development to reduce energy consumption and increase energy efficiency. ${ }^{(1)}$ (1) Isle of Man Strategic Plan 2007 (2) UK Department of the Environment General Information Report 27 - Passive Solar Estate Layout (3) Definition From Appendix 1 of Isle of Man Strategic Plan 2007 - 'Energy Impact Statement: An assessment, prepared by the developer/applicant, of the impacts of the development in terms of energy consumption and proposals for reducing that consumption and improving the energy efficiency of the development.'
The attached document is a suggestion of a possible format for an Energy Impact Assessment as required by Energy Policy 5 of the Isle of Man Strategic Plan.
The headings for the Energy Impact Assessment have been drawn from the following documents:
Town and Country Planning Act 1999 - Isle of Man Strategic Plan 2007
UK Communities and Local Government documents: 'Code for Sustainable Homes - A Step-change in sustainable home building practice'. 'Regulatory Impact Assessment Energy Performance of Buildings Directive Articles 7-10'
BRE BREEAM Ecohomes Standards and Sustainability Checklist (including Pre-Assessment Estimator) Sustainability Checklists - Woking Borough Council Energy Saving Trust - Passive Solar Estate Layout (specifically referred to in 12.2.10 of the Strategic Plan) Town & Country Planning Association (TCPA) 'Planning for Sustainable Energy'

Dear David
I refer to your request for advice in relation to the proposed residential development for some 45 dwellings on land to the west of Oak Road and to the south of existing properties served by Fuchsia Avenue.
Oak Road performs the function of a local road that connects with A20 Poortown Road to the south at a four-arm roundabout junction and with A4 Ramsey Road to the north at a four-arm roundabout junction. In addition there is also a connection to the wider highway network at Ballaquane Road via Rowan Avenue. Oak Road provides frontage access to residential development and provides access to other residential areas by way of a series of simple priority controlled junctions that provide access to designated Home Zones.
In the vicinity of the proposed residential development site, Oak Road has a carriageway width of some 6.1 metres with a segregated 1.8 metre wide footway along the site frontage and a grass/soft landscaped verge to the opposite side. It is subject to a 20 mph speed limit, is lit and is traffic calmed through a series of road humps and localised priority controlled narrowing at the southern corner of the site. Oak Road is a bus route and is subject to a weight restriction of 7.5 tonnes, except for access. Along the site frontage, Oak Road has a straight alignment and at the southern corner of the site, Magher Breek, a residential access road designated a Home Zone, connects with Oak Road.
The proposed residential development can be served by a simple priority controlled junction with Oak Road. Such a junction is capable of providing minimum visibility splays of 2.4 metres $\times 22.0$ metres in accordance with advice in Manual for Manx Roads for major road

speed limits of 20mph. The proposed shared surface loop arrangement within the site accords with advice in MfMR and provides a permeable site layout for all users that connects with the highway network. The layout provides for service vehicles to enter and leave the site to/from Oak Road in a forward gear.
Residential development typically generates between 0.6 and 0.8 vehicle movements per dwelling during the morning peak period, 75% of which are likely to be leaving the development. Based on the higher figure of 0.8, a development of some 45 dwellings will generate only some 36 vehicles between 8:00am and 9:00am with 27 departing and 9 arriving. This equates to one vehicle every 1 to 2 minutes using Oak Road. This level of additional movements will not be noticeable and hence will not have a significant impact on the local highway network. Furthermore 'Guidance on Transport Assessment' advises that for developments less than 50 units no assessment should be required.
I conclude that the proposed development can be safely accessed from Oak Road and the traffic movements likely to be generated by the development will not have a material impact upon the operation of the local highway network.
If you require any further advice at this stage, please let me know. Yours sincerely
