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…
