UNEMAT 2012/1

Everyone says that we must use less energy! But how? That is the

big question. In this article, you can read about the house of the

future, which uses hardly any energy at all...

Most houses use energy - lots of it. We use energy for heating,

[5]  lighting, for running our household appliances - TV's, washing

machines, fridges, and so on. In winter time, most houses use

dozens of kilowatts of electricity every day, or the equivalent in

gas.

The house in the photo, on the other hand, uses virtually nothing:

[10]  most of the energy that it uses comes straight from the sun, the

wind or the ground. This is an experimental house at the University

of Nottingham, and it could be the kind of house that most people

are living in fifty years from now.

During the daytime, it is rarely necessary to turn on an electric

[15]  light, even in rooms without windows. Sunlight, or daylight, is

"piped" through the house, into each room, through special highreflection

aluminium tubes. You can see how well they reflect light,

by looking at the reflections of the faces in the picture!
