Making Your Home Energy Efficient
For most people, the place where you have the most opportunity to make choices which will save you energy - and money - is in your home. There are many things to consider, each one taking you a little further in your quest for energy efficiency.
Insulation
Insulation is one of the best ways of lessening the amount of energy you need to use in heating and cooling your home. Different insulation materials have different ratings, so before taking up just any insulation offer, look into what they are offering. Consider ceiling insulation to R4 or higher, and wall cavity insulation targeting east and west facing walls.
Windows & Dressings
Energy use can be cut by having appropriate windows and their 'dressings'. Blinds can keep out heat, or cold, and can be used to shade walls too, not only windows. Heavy, thermal curtains keep the exchange of temperature with the outside at a minimum. Consider tinted or double-glazed windows for maximum efficiency.
Ventilation
Ventilation is an important aspect of creating an energy efficient house. It can help release hot air to the outside and also move cooler, or warmer air through the house to stabilise the temperature. Ceiling fans are an effective and energy-efficient way to circulate air.
Lighting
Choose energy efficient lighting, including use of sensors. LED lights use significantly less energy than traditional bulbs and last much longer. Consider natural lighting in your design to reduce daytime electricity use.
Sealing
Seal doors, windows, vents and exhaust fans. Self-sealing exhaust fans are an option. Proper sealing prevents drafts and maintains internal temperature more effectively, reducing the load on heating and cooling systems.
Start Early for Best Results
Ideally you would have engaged a thermal performance assessor from the planning stage of your project. This allows for the most cost-effective implementation of energy efficient features and ensures your home achieves the best possible rating.
