# Introduction

This free course, Energy in buildings, looks at the importance of energy in buildings in the UK, particularly housing. Topics covered include reducing the heating demand of houses, improving their heating systems and reducing the electricity used by appliances and lighting. These are all methods of reducing their overall CO2 emissions.

This OpenLearn course is an adapted extract from the Open University courses T213 Energy and sustainability and T313 Renewable energy. It should take about 10 hours study time.

You will need a calculator handy (perhaps within your computer) to answer some of the course questions.
