Energy Impact Assessment/Statement

Energy Impact Assessment

Background

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.

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. Added to this are the various solar panel, photovoltaic cell, solar energy and heat pump technologies.

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 to demonstrate what measures have been taken in the design of the development to reduce energy consumption and increase energy efficiency.

(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'
