Drivers - People…  Our Main Aim: “The provision of Excellent Affordable Housing”  “Affordability” not only driven by our Rent Policy, but also the need to reduce energy costs to which tenants are exposed  BHA based in Low Income Area  Some of our tenants suffer from Fuel Poverty  Provides tenants with more disposable income and generally leads to healthier lifestyles  Approach implemented since inception of BHA September 1995

Drivers – Buildings, Environment…  We have responsibilities to ensure: our properties are future proofed to protect people against rising energy costs; deliver improved air quality within the building envelope; and reduce the impact of existing and new stock on the environment  Berwickshire benefits from the highest levels of solar irradiation in Scotland – we’re ideally placed  Scotland has 25% of Europe’s wind resource; let’s use it! In autumn 2002 the Scottish Executive consulted on a proposal to set a target that 40% of our electricity comes from renewables by 2020…
