Making Your Renovation Energy Efficient

February 15, 2019




















What makes a renovation energy efficient?


If you are about to renovate or extend your home you can make this major investment more energy efficient and comfortable.  Incorporate simple design features into your renovation or your new home, your home will be warmer in winter and cooler in summer saving on energy bills.


Look at the following components:

  • Building Design

  • Building Materials

  • Window size and placement

  • Fixtures

  • Draught proofing and weather sealing

  • Heating systems

  • Hot Water System

  • Lighting

#Building Design

  • Ensure living areas face north to take advantage of the winter sun and natural light.

  • Clever renovation design can compensate for a badly oriented building so seek expert advice.

  • Contact the Energy Smart Information Centre for a list of builders and designers who specialise in energy efficient housing.

Building Materials

  • Concrete floors and masonry walls (such as cavity brick or feature brick walls) can stabilise temperatures in rooms with north-facing windows by thermal mass to absorb heat in winter.

  • Lightweight materials such as timber or plasterboard, used internally will allow rooms to heat up and cool down quickly.

Window Size and Placement

  • It is important to have the right size windows in the right places to allow the winter sun in and the summer sun out.

  • Allow cross ventilation in the house to eliminate the need for Air-conditioning. 

  • Use casement, sliding or double-hung windows.


  • Reduce heat loss through windows with lined close fitting drapes, tight fitting Holland or Roman blinds with pelmets or double glazing

  • Unprotected skylights and roof windows  can be a major source of heat loss in winter and heat gain in summer.

  •  Keep skylights as small as possible and install double glazed skylights.

Draught Proofing and Weather Sealing

  • Look for obvious gaps under windows and doors

  • Ventilate bathrooms, toilets and laundry to avoid damp and mould

Heating Systems

  • The most efficient and cost effective way to heat your home is to use one or more space heaters or a zoned central heating/cooling system.

  • Ceiling height and room placement must be taken into consideration


Hot Water System

  • Install an energy efficient system (gas, solar or heat pump)as near as  possible to the kitchen, bathroom and laundry.

  • Install a unit that is the right size for your needs

  • Insulate hot water pipes

  • Use AAA rated shower heads


  • Make good use of natural light especially in living areas

  • Paint your walls and ceilings in light colours

  • Use compact fluorescent lights in living areas

  • Large banks of recessed lights, or downlights should be avoided
