Passive Solar Design
Thermal mass acts to control temperature swings from night to day. If this house has floors and walls which can recieve and store this energy for later release after the sun goes down will utilize this energy during the day and night. They heat up too quickly and conversely give up it's heat too fast. Dark colors of stone, cement, tile, adobe brick, and masonary make a good battery for solar radiation, or what is otherwise know as "Thermal Mass". The battery portion of the house are the materials and mass that is contained within it's walls that have the capabilities of storing the solar radiation that comes through the windows. A house that is properly oriented with enough windows facing south will recieve a large amount of energy on a sunny day in the middle of winter. How efficient is your house as a battery, that is, how well does it charge up and save the free heat that the sun provides during the day and how well does it give back this heat during the night when! needed? Conventional materials such as gypsum wall board for walls and wood floors make for poor storage of solar energy. Obviously, good insulation is a paramount component to good passive solar design.
To view illustrations of my Pasive Solar Energy design for a house that I am building in southwest Colorado, visit my website listed below.
Jerry McElroy is a writer, photographer, and artist who is building an energy efficient, off-the-grid, straw bale house in Southwest Colorado.
Passive solar design takes advantage of both summer and winter sun angles for free cooling in the summer and heating in the winter. How cool (or hot) is that? http://www.labocavista.com is an on-line documentary which explains the design and components of the house and discusses the environmental challenges that we as humans face.
One way of thinking about your house when it comes to the sunshine that falls upon it everday is like that of a battery. Conventional construction without the attention to passive solar design can over-heat during the summer days and require mechanical cooling and cool down during the night in the winter requiring mechanical heating. Larger roof overhangs will block the sun from entering the house during the summer when the sun is high in the sky but allows it to enter the windows and warm the thermal mass when the sun's angle is low in the winter time.
Passive solar gain,... it's free and completley pollution free! It can be as simple as paying attention to the orientation of the house, placement of windows, the length of the overhang of your roof, and the kind of floor and walls chosen.
