Low and zero carbon homes-Delivering genuine sustainability and avoiding unintended consequences

Let\´s start looking through the correct end of the telescope and focus on the real imperatives: (1) the existing building stock; (2) installing large-scale renewables where they will be most cost-effective; (3) ensuring that the new buildings are ultra-low carbon and incorporate renewable technologies which are correctly sited, cost-effective and reliable (including the optimised use of passive renewables); (4) adopting a "whole system" approach and deliver spaces, places and buildings which are genuinely sustainable; (5) healthy, safe, productive and inspiring; (6) fit for people and the planet; and (7) sustainability is more than zero carbon and can\´t be bolted-on: - it must be "in-built".
