The consent authority must not consent to development for the purpose of buildings unless it has considered the following matters that are of relevance to the development--
(a) the extent to which potential energy consumption may be reduced during the construction, occupation, utilisation and lifecycle of proposed buildings,
(b) the extent to which sustainable natural resources, such as the sun and wind, will be used in proposed buildings to create naturally comfortable living and working environments,
(c) the extent to which proposed building materials and construction techniques are ecologically sustainable and will--(i) minimise the expenditure of energy (including, in the case of building materials, any expenditure of energy involved in their manufacture), and(ii) maximise the useful lifecycle of proposed buildings.
