Would you like to make use of natural surroundings to take down energy consumption and simultaneously enhance the comfort, value and sweetness of your house? It is exactly what passive home design is about. With intelligent planning of the new house design, room layout and orientation you are able to improve natural lighting, interior comfort and cut costs.
This is accomplished by designing your brand-new the place to find harness solar energy, disbursing solar energy with thermal mass, stopping heat loss or absorption with improved insulation as well as an airtight envelop.
Passively harnessing solar energy is about orienting your house to maximise the southern exposure. Throughout the winter several weeks the sun’s position towards the horizon at noon is as little as 30%. Even while it’s cold outdoors the sun’s rays continues to be emitting quite a lot of energy that may be taken to warm your house. This is accomplished by designing an area layout so the greatest rooms using the greatest home windows face the south.
On the other hand, throughout the summer time the sun’s position to horizon at noon is up to 78%. Once more, with a few simple planning, it’s not hard to deflect solar energy in the interior. This is accomplished utilizing a sufficient roof overhang to shade your window areas. Furthermore, most new home windows are coated having a special material that reflects solar energy at high angles and accepts it at low angles for example winter season. Performing these simple tips will assist you to keep the home awesome and comfy on the hottest days.
Once your house is correctly oriented to soak up or reflect solar energy after this you introduce thermal mass for your design. Thermal mass is heavy material like water, concrete, masonry, tile and rock that readily absorbs or emits heat. A few of the methods for building in thermal mass are tile or concrete floors and interior rock or masonry walls. To become more efficient design the non-thermal mass areas, like ceilings and walls produced from drywall, to mirror solar energy towards the thermal mass areas. Among it is really an exterior patio that reflects the reduced sun sun rays in the ground, with the home windows, towards the ceiling after which lower towards the floor or walls.
A house designed such as this creates a lot of its warmth in the sun’s free energy throughout the day as being a eco-friendly house. During the night the thermal mass releases the stored heat energy assisting to maintain indoor comfort.
Throughout the summer time the thermal mass cools off during the night. After that it absorbs heat within the day once more assisting to regulate indoor comfort.
Since your house is utilizing free energy the next thing is to avoid exterior climate conditions from entering your house. This made by many home builders with advanced insulation giving no less than r-50 within the ceilings, r-21 within the walls and r-30 within the floors. Many home builders include additional insulation like foam board which will help to avoid thermal bridging. To avoid air leakage all home penetrations and joints are caulked making the house virtually airtight.
