how to paint a brick house – Basic Info

There is no doubt about it, an energy efficient home is a cost effective one. One of the ways on how to save energy and make your home energy efficient is to design a new house properly and make use of the correct building materials.

In the old houses in Australia and South Africa, bricks have long been chosen as building materials. Nearly 90% of all the houses in these places are constructed using bricks, and still are today. Nowadays, in an effort to improve the energy efficiency of homes and for ways on how to save energy, building regulations require the newly built houses to use the right materials. Here are some points you should know that will help you come up with an informed choice. click to read on recoloring the exterior of my brick home in Central PA.

As you are probably aware, most of the energy consumed in the home is used for cooling and heating purposes. Therefore, any effort that can reduce the cooling and heating requirements of your home will be a good one, right? But, do you think it is possible to reduce your cooling and heating energy consumption while keeping up the thermal comfort of your home? This is where passive home design plays an important role.

In passive home design, the incoming energy from the sun is used to improve the house’s cooling and heating characteristics in a natural way. Four major principles make up passive home design. These principals are orientation, ventilation, insulation and thermal mass.

Here is a simple example how orientation can affect your house’s cooling and heating characteristics. If you live in the northern hemisphere, south facing windows would let the sun in during winter, assisting in heating your home. While during summer the sun is high in the sky, which will keep your house cooler as less surface of the window is exposed to sunlight.

Cross ventilation is important. To facilitate cross ventilation, either side of the house should have sufficiently sized openings with almost no internal obstructions. This allows air to get in and out of the house in order to naturally cool it down.

Insulation in walls and ceilings acts as obstacles to heat conduction. The efficiency of insulation is characterised by the insulation material’s R-value. But it is not only the R-value that one has to consider. The thermal mass is another important factor to keep in mind.

Thermal Mass.
Typically, dense and heavy materials, like bricks, convey heat better through the walls. However, due to their thermal mass, bricks can absorb much more energy. Temperature differences then become small and the heat absorption into the house during summer is significantly reduced. Lightweight materials, compared to brick walls, have very low thermal mass. It is because of this thermal mass that brick walls are much better at moderating your home’s temperature.
