It seems obvious, but it is sadly often
too true that new homeowners make some classic mistakes when orienting their
new luxury home within their building plot or in choosing a building
plot which offers the essentials for good orientation. In particular it is vital to think carefully about building
orientation and energy consumption when building your new home.
Building orientation is important in
reducing energy consumption and keeping the interior temperature comfortable. When designing and siting your new home within your
building plot, it is necessary to think about using the sun to your advantage. As we all know, the
sun rises in the east and sets in the west, and is higher in the summer sky and
lower in the winter sky. Therefore the orientation of the whole building
should be planned and constructed to capture free heat in the winter and
minimise too much heat in the summer. Since you live in your home through summer and winter, you should design
it for the entire year. The ideal house
orientation is that the main long axis (the ridge line) of the building runs
from east to west. It is generally agreed that you can move this
orientation by as much as 20 degrees without ill effect, but that the
most glass finishes on the building should face towards the sun.
When choosing a plot or
deciding the building orientation of your new home within a plot it is
important to take into account the location of landscape features on the
building plot, for example trees and walls, which may impact on how you harness
the sun for your home. Ideally you do not want landscape features blocking the
sunlight as the sun tracks across the sky.
When planning your
building, think about where to locate your living areas. The rooms most
used must be on the side of the house orientated towards the sun, i.e. the
kitchen, lounge, dining etc. The least used rooms such as garage, laundry etc
will be on the more shaded side of the house. These shaded rooms can also
act as additional thermal mass, if properly insulated. (Thermal Mass is material that absorbs heat from a heat source, and then
releases it slowly - such as concrete or bricks). Thinking through how your home will relate to
your garden is also vital, providing sun-filled sheltered areas adjacent to
house interiors to allow seamless indoor/outdoor living spaces.
When buying a building plot and planning and designing your new home, a
sustainable, whole house approach to design and construction is
essential. For more information on passive solar design click here>
