2. When drawing your plan, try and add as much detail as you can, labelling different features, such as double glazed windows and cavity walls. Draw two separate plans; one draft and one final copy (remember to use rulers and a sharp pencil as you would in Science)

3. The Basics Draught proofing is one of the cheapest and most efficient ways to save energy in any type of building, from a flat to a mansion – but it’s often overlooked. To draught proof your building you should block up unwanted gaps that let cold air in and warm air out. By saving warm air you’ll use less energy to heat your building. The savings Full draught proofing will save on average $50 per year. Blocking gaps around skirting boards and floor boards could save another $40 per year. Draught-free homes are comfortable at lower temperatures – so you’ll be able to turn down your heating. This could save you another $100 per year. What Can be Draught Proofed? Windows Doors Chimneys and fireplaces Floorboards and skirting boards Loft hatches Pipe work Old extractor fans Cracks in walls Useful Website http://www.energysavingtrust.org.uk/Home-improvements-and- products/Home-insulation-glazing/Draught-proofing

4. Did you know that around a third of all the heat lost in an un-insulated home is through the walls? Insulating cavity walls reduces heat loss and can save you around $150 a year on your fuel bills. The Basics Home built from 1920 onwards have external walls that are made of two layers with a small gap or ‘cavity’ between them. This means they have 'cavity walls'. Insulating your cavity walls means filling that gap - with very good reason. ? No heat can now be transferred by convection because the air has been replaced by insulating materials. Conduction is very poor because both the insulating material and the trapped air are good insulators. The room in the house stays warmer for longer

5. The Basics All properties lose heat through their windows. Installing energy efficient glazing is an effective way of reducing your energy bills and keeping your home warmer and quieter. Double glazed windows use two sheets of glass with a gap between them which creates an insulating barrier, whilst triple glazed windows have three sheets of glass. Both options can deliver a high level of energy efficiency. It is not the case that you have to use triple glazing to gain the most energy efficient window. What it can do Smaller energy bills : replacing all single glazed windows with energy efficient glazing could save you around $250 per year on your energy bills. A smaller carbon footprint : by using less fuel, you’ll generate less of the carbon dioxide (CO 2 ) that leads to global warming. A more comfortable home : energy efficient glazing reduces heat loss through windows and means fewer draughts and cold spots. Peace and quiet : as well as keeping the heat in, energy efficient windows insulate your home against unwanted outside noise. Reduced condensation : energy efficient glazing reduces condensation build-up on the inside of windows (useful for humid rooms or buildings).

6. The Basics Insulating a hot water cylinder is one of the simplest and easiest ways to save energy and money. Fitting a 'jacket' around your cylinder will cut heat loss by over 75%. Both tank and pipe insulation keep your water hotter for longer by reducing the amount of heat that escapes. What the cost? What does it Save? A new, 75mm thick hot water cylinder jacket will save you around $70 per year. The jackets themselves cost less than half that, meaning that you can reclaim your initial cost in less than 6 months. Insulation for hot water pipes will cost around $20 and can save you around $30 a year, which means you should recover the cost of fitting within a year.

7. Did you know that in an un- insulated building a quarter of your heat is lost through the roof. Insulating your ceiling is a simple and effective way to reduce your heating bills and you can even do it yourself. The Basics It's never been more important to think about insulating your ceilings and walls. Without proper insulation a lot of the valuable, expensive energy you use to heat your home will be lost through the loft. The recommended depth for mineral wool insulation is 270mm however there are other materials which require different depths. ?

8. The Basics Timber floors can be insulated by lifting the floorboards and laying mineral wool insulation supported by netting between the joists. You can also use a regular tube sealant, such as silicon to fill gaps between floorboards and skirting boards to stop draughts. Costs and Savings Using a silicone sealant to fill gaps will save you around $40 a year on your heating bills. Insulating underneath the floorboards on the ground floor will save you around $100 a year.
