Reduced load on air conditioning systems and the associated costs with running them.
Choosing an appliance
When choosing an appliance or product, just don't look at the price and features.
Also have a look at its energy consumption.
If money is your only driver for selecting an appliance, compare the costs of the appliances and their running costs over the expected lifetime.
This is the simple method and not completely accurate. The correct way to analyse costs is to do a Net Present Value (NPV) analysis, which takes into consideration the future value of money. For a small fee, Punchline Energy can compare the total lifetime costs of products or appliances.
Just send an email with the following information for each product or appliance.
Purchase price, daily energy consumption, cost of energy and product lifetime.
