energy efficient buildings

In preparation for my experiment this week, ‘envisioning future infrastructure’
Ive been doing some research into an important part of future wellington: Energy efficient buildings.

From my research Ive discovered that there are 5 key aspects to having an energy efficient building or home. These are as follows:

1 – Placement and design,

Position a building in such an orientation that it takes advantage of the natural resource that are around the ares such as morning sun or prevailing winds can make a huge difference to the costs associated with the continued running of the buildings.

2 – Insulation,

This is super important to making a building that doesn’t waist it energy on heating or cooling. As it turns out it is also important to make sure that it is reasonably well sealed so that you dont get air drafts but still main tain good ventilation in rooms like the kitchen or bathroom.

3 – Efficient heating/cooling

It no good having a house that retains heat well is the heat source is wasteful, Its important to have an aircon system that is as optimised as possible so to avoide wasted energy used for heating or cooling.

4 – Decrease energy use

This is an obvious but important factor. By doing simple things like reducing the amount of hot-water that is stored and turning off electronics when not in use the savings can be huge. Also having lighting that isn’t wasteful and only lights areas that are needed rather than large ambient areas.

5 – Local generation

Finally generating some power, no matter how small amount reduces the load on the national grid. Also depending on your energy needs excess power produced during the day can be sold back to the grid for credits to be used at night when your solar panels aren’t active. In this way the grid effectively acts as a battery for the house hold, buying any excess power produced during the day while the family is out and then selling them back power from there other sources at night.

    New Zealand is already heading in the right direction with the Government funded “Warm Up New Zealand: Heat Smart programme” So it’ll be good if we can build upon that
