There are a number of design features and fittings that can improve bathroom energy efficiency and reduce energy bills and greenhouse pollution. Remodelling your bathroom to make it more energy efficient will improve your home because doing it right will reap the benefits of health, safety, comfort and will save you money and energy.

1. Energy Efficient Hot Water System
Select an energy efficient hot water system and place it as close to the bathroom and laundry as possible to reduce pipe length and reduce heat loss.

2. Energy Efficient Labelled Ventilation Fans
Bathroom moisture is often controlled by the use of an exhaust fan. The fan sucks out the moisture-laden air, which is then replaced by drier outside air.

Install properly sized energy efficient labelled ventilation fans to control moisture in the air while you shower or bathe. By removing moist air and drying out your bathroom, a ventilation fan will help prevent mold and mildew. Fans help remove moisture, which can increase the level of humidity in your house. High humidity can damage building materials. Worse, high humidity can cause mold growth and mold may affect your family's health. Install self closing exhaust fans to avoid heat loss or gain when not in use

3. Energy Efficient Labelled Lighting
Another easy way to make your bathroom more energy efficient is to install energy efficient labelled lighting (e.g., Light Fixtures: suspended lights, ceiling-mounted lights, cabinet lights, recessed lights, or compact fluorescent bulbs). Attractive, energy-efficient lighting adds value to your home and reduces home energy bills.

4. Insulation - Insulate Walls and Ceilings
The walls behind tubs or showers are often poorly insulated and air-sealed. Opening these walls as part of the remodelling project provides an opportunity to ensure comfort by sealing air leaks with caulk or expanding foam and installing insulation. Also make sure to air seal around plumbing and electrical penetrations.

5. Energy Efficient Windows and Doors
If you are replacing windows, doors, and skylights, consider those with the energy efficient label. New technologies in the glass and frame systems help make your home more comfortable, and lower heating and cooling costs too.

6. Energy Efficient Showerheads
The shower is the largest user of household hot water. Install an AAA showerhead to reduce the amount of hot water consumed. AAA showerheads are available at many bathroom supply stores and hardware stores. A flow rate of approximately 7L per minute is considered as AAA for showerheads.

7. Water Pipes and Water Saving Devices
Insulate hot water pipes to reduce heat loss and save energy. Install water saving devices like water saving aerators and flow regulators in your taps. Select water saving taps that have a similar water saving rating.
