When you heat an uninsulated home, heat escapes, particularly through the ceiling. You are required to keep the heater on to maintain a comfortable temperature while the heat and the cost, goes through the roof.
Generally speaking, if you get your orientation, design and passive systems (including insulation) right, you’ll spend less money in the long term to heat and ventilate your home adequately.
Installing the correct level of Pink® Batts® insulation in your home will help you save on your power bills and over time will 'pay' for itself.
According to BRANZ research, the cost of installing ceiling insulation in an otherwise uninsulated house in Wellington would be paid back by the savings in heating costs in 4 years. After 20 years this homeowner would enjoy a net saving of over $3,000.
It takes a 1% increase in the cost of building a new home to increase your thermal insulation from the New Zealand Building Code (NZBC) minimums to the highest levels of Pink® Batts® Ultra®. The higher R-values over the NZBC minimums decreases the energy used in heating and cooling by up to an extra 30%.
Sun is great heat source so orienting your home to take advantage of sunlight will mean less energy is required to heat it.
Taking advantage of the natural warmth of sunlight during winter can assist in saving energy cost to heat your home. Conversely, shading windows from direct sunlight can help stop your home overheating during summer and incurring cost to cool it.
