Why Are Sun and Shadows of Value?


As our world is encountering a crisis of the need to replace non-renewable resources, the value of solar technology is becoming more evident and in being utilized with solutions and alternatives to gas and electricity.
 
Rooftops are not the only part of the house that need sunlight, especially during the winter. The walls themselves need sun as they are retainers and play a vital role in maintaining warmth during winter months. If they do not receive sun, the overall need for more energy to heat the home and run the heater continuously is excess usage of energy.
 
 Using what the ancient civilizations knew, positioning of shadows strongly affects an environmental opinion of the important and impact that shade does provide (both positively and negatively).
 
Solar panels, Solar Home Design, Trombe Wall, etc are the new terminology for building homes and utilizing renewable resources.
  
To utilize solar gain, though, you need to be able to control how much shade falls on your roof. During the winter, in order for maximum absorption of the sun’s energy, a home would function at it’s best without shade. During the summer, shade would be desirable to cool the home.
  
The concept of Solar Home Gain is not new. Ancient civilizations such as the Puebloans of Mesa Verde built Cliff Dwellings facing south to maximize solar gain during the winter and to provide shade during the summer.
  
They had studied the sun positioning (high during summer providing shade and long during the winter to cast sunlight and warmth into the caves). Most of the cliff dwellings were oriented to collect solar energy as a result of the positioning of their architecture.
 
We can do the same.
