6 Key Areas for improving Energy Efficiency in your Home

Creating a sustainable, energy efficient home is environmentally friendly, improves the health and comfort of your home and reduces your spend on energy bills. What’s not to love. 

So let’s look at some key areas that could really impact the environmental sustainability of your home and improve your homes coziness at the same time. 


When cold draughts are forcing their way into you home, it makes it especially hard to heat and maintain heat in your home. A low cost, fast solution is to block these gaps with draughts excluders that you can purchase from your local hardware store. For a longer term solution, at Cozy NZ we can look at joinery and glazing solutions to combat bad draughts and increase comfort levels. 


Heating your home improves comfort levels and is vital for a healthy home. 

Ensure you have a clean heat source that is safe and as efficient as possible. 

If you are using a fireplace get your chimney swept regularly and burn dry wood. 

If you are considering upgrading your heating system pay attention to energy star ratings and opt for the most efficient models, they will save your money in the long run. 

Become savvy on the best temperature to set your house at, each degree adds cost to your bill at the end of the month. 


Consider upgrading single glazing to more energy efficient double glazing. 

Heat escapes fast from old single glazing, also letting in heat quickly over the summer months making energy bills for heating and cooling much higher compared to homes that are double glazed. 

Double glazing also reduces condensation making for a healthier home.

Cozy NZ can retro fit double fit glazing as well as offer glazing solutions with inserts and full replacements for window and door joinery. Talk to our team if you need advice or solutions in this area. 

Window coverings 

Window coverings help keep the heat in, aim for two layers of material and ensure coverings touch the ground where possible.  If you are considering upgrading do your research and talk to an expert to ensure you are selecting the right window coverings for your home and space, window coverings not only look great but they can help the sustainability of your home if chosen and used correctly.


Insulation has a huge impact on your homes heating and cooling efficiency. Ensuring you have adequate insulation in your walls, roof, under floor and crawl spaces will go a long way to helping reducing heat loss in the home. 


Consider using a dehumidifier or installing a ventilation system to help reduce 

condensation, mould and dampness. Use windows to ventilate your home and try to line dry clothing.
