For people planning to build a home and the idea is to have Green Home that offers the owners the chance to make use of renewable resources to save money, then proper orientation of the new home is important. Orienting a new structure to accept the warmth provided by the sun during winter months while avoiding extreme heat in the summer is actually not a new thing. Ancient Roman and Greek homes were oriented and then built with the idea of seasonal exposure. Certain facts influencing building orientations never change. The sun rises still in the east and it sets still in the west. By midday during winter the sunlight is at low angle and at high angle during summer. These are facts that do not change; therefore they should be taken advantage in planning for home building. It is important to position a new structure accordingly so that the daily, as well as the seasonal, motions of the sun can be used in increasing indoor comfort while significant reduction of cooling and heating expenses is also possible.
Benefits of Maximizing Southern Exposure
Sunlight is natural and it is a great source of free warmth. Since daylight is free and sustainable there is no reason why anybody should ignore its power that is readily available. By positioning your home properly according to the movements of the sun you will be able to save energy while creating a healthier and more comfortable living space for you and your family.
Affordability is indeed a good advantage and the cost of trying to maximize sunlight is going to depend on what measures you are going to take. For instance, rearranging your furniture is free and all it takes is some efforts on your part. Other measures can be really inexpensive like painting your wall with lighter reflective paint. Some measure though may require a bit more investment (like installation of light shelves and retrofitting skylights and windows), but will surely pay off in the long run. Harnessing the natural energy from the sun by using solar-powered lighting in illuminating paths and landscapes is also a recommended measure to take.
Maximizing the ability of using a valuable resource like sunlight is indeed helpful in keeping the lights off at daytime and in saving money every minute.
When you make use of the sun’s power to warm and light your home, you are also saving the environment from total destruction. Use of daylight doesn’t need electricity generation and it eliminates greenhouse gasses emission, thus you are making it possible to save the Earth. Additionally solar power utilization involves very little product resource manufacturing, extraction or shipping.
What Should Be Done
For New Homes
Basically, the steps are simple. One good measure to consider is facing the front side of the structure within twenty degrees on the true south. This positions windows that are south-facing and will give them the ability to effectively collect solar energy that will bring in heat inside the home during the cold winter months. It is important though to know that not all windows facing south are going to be effective solar collectors. The degree measurement and the size of the window are important factors. Large windows that are facing extremely to the southwest may overheat the home interior during summer months, and structures that are positioned extremely to the southeast may not get the required sunlight and warmth when winter comes.
Dispersing the light is important and this can be achieved by a properly positioned south-facing window that can illuminate the area from 20 up to 100 times more. When you disperse the light, you reduce glare and heat while you also reduce overhead lighting use.
Painting your ceilings and walls in reflective light colors is also a good idea as well as use of sky tubes or solar lights. You would also benefit well from the power of the sun by installing light shelves that can be useful in reflecting light deeper inside large rooms.
For Existing Homes
For an existing home the best way to take full advantage of the benefits of the sunlight is to start on making renovations. Renovations usually equate high costs but that shouldn’t be the case if you know what to do. The first thing that should be done is to use the resources available. It is also a recommended step to consult a home designer or contractor that is experienced and skilled in passive solar, heating/cooling and electrical design techniques.
It is a good idea to adjust Venetian blind angle so that the light can be aimed where it is needed. When you angle the blind towards your ceiling, light is reflected downwards with no heat gain. Using blinds is ideal because it can reduce the entry of unwanted glare and heat, while you can still benefit from the warmth and the light of the sun.
There are a lot of things to take into consideration if you want to maximize the benefits that can be provided by the power of sunlight. Maximizing southern exposure is one significant consideration. This is a measure that will provide your home with needed shade during sunny summer days. Additionally, proper orientation is going to give you the opportunity to take advantage of sunlight so your home is provided with the required warmth and light during the dark and cold winter days.
If you are building a new house or planning on renovations, getting professional help is a good idea. Professional designers can make your residence a structure that is more affordable to cool and heat. Aside from being energy-wise, proper orientation of your home is also going to give an abode that is highly comfortable and healthier to live in.
Make day-lighting an essential concern in your home building or renovation project by maximizing southern exposure. Daylight is free and it is abundant. It offers natural light and warmth that will give you the chance to save energy, save the Earth and save you and your family’s health.
