The thermal mass, a 6-18 inch thick masonry wall, is located immediately behind south facing glass of single or double layer, which is mounted about 1 inch or less in front of the wall’s surface. Solar heat is absorbed by the wall’s dark-colored outside surface and stored in the wall’s mass, where it radiates into the living space. Solar heat migrates through the wall, reaching its rear surface in the late afternoon or early evening. When the indoor temperature falls below that of the wall’s surface, heat is radiated into the room.

Passive house and passive solar - free heat for homes
SIPs are sandwich panels with solid polystyrene (styrofoam) in the middle and oriented strand board structurally laminated to each side. One of the advantages of SIPs is that, if properly used, they are almost airtight, so a home will have minimal air infiltration. Keep in mind that you would also likely need to use mechanical ventilation, such as an energy recovery ventilator, for an airtight house to maintain indoor air quality while also maximizing energy efficiency. The light can be from passive windows or skylights and solar light tubes or from active daylighting sources. In traditional Japanese architecture the Shōji sliding panel doors, with translucent Washi screens, are an original precedent. International style, Modernist and Mid-century modern architecture were earlier innovators of this passive penetration and reflection in industrial, commercial, and residential applications.
The Tally: The Cost of Building a Solar Home
An indirect-gain passive solar home has its thermal storage between the south-facing windows and the living spaces. Passive house design principles are gaining traction worldwide as an effective way to minimize energy consumption in buildings. Typical homes allow unwanted flows of energy between the exterior and interior. The Kalyon Energy Control Building by Bilgin Architects in Karapınar, Turkey, exemplifies sustainable design through its innovative response to a challenging desert environment. The high-reflectivity stainless steel facade minimizes heat gain while creating a visual connection to the vast solar panel field it manages. This strategic placement and material choice underscore the project’s commitment to energy efficiency.
Is SunPower Still The Best Solar Company For Solar Panels?
In cool or moderate climates, a passive solar house will not require any air conditioning and will be comfortable inside simply with natural nighttime ventilation cooling. When the outdoor temperature drops below the inside temperature, you just open up the house and let it breathe. In hotter, drier climates, you might consider an evaporative cooler (such as those at Coolerado) to supplement cooling.

These engineered lumber products utilize materials that would otherwise be waste, composite decking made of recycled plastics, and more. The basic form of this home is what I call the “Western Solar Farmhouse.” The floor plan is arranged around a central great room with a high-vaulted gable roof. Around the sides of the central great room are grouped rooms or porches with a lower-pitched hipped roof. The porches can go around all sides as they do in the classic plantation house design that’s built in tropical climates with shade cooling and “outdoor” rooms. The Western Solar Farmhouse’s central living area is typically a rectangle, and the solar gain rooms would usually be located on the long solar side.

As part of a top-to-bottom renovation, consider installing a geothermal heating and cooling system to conserve energy. They work by tapping into stable temperatures a few feet below the earth’s surface to heat and cool a home. Poor heat and moisture management are the enemies of durable, comfortable, and efficient housing, and good building design and construction starts with a solid understanding of good building science. In the meantime we decided to maintain our old farmhouse as best we could and be thankful for the roof over our heads.
I usually recommend clear double glass for solar-oriented windows and “low-e” glazing on the other sides. Low-e glazing limits incoming heat in summer and reduces heat loss from the inside in winter. Using clear glass on the south wall windows allows more of the sun’s energy to warm the house in winter, when the sun will be able to enter the house through the south-facing windows. In colder climates, using insulative window drapes or blinds at night helps reduce overnight heat loss and increase comfort. Sunrays may fall on a wall during the daytime and raise the temperature of its thermal mass.
Net-zero energy homes
The greenhouse should allow us to grow more foods over winter, and startseedlings early for the main garden. This is a picture of Liz with a harvest fromour winter (outside) garden taken in February of 2004. To reduce unwanted heat gain in the summer, all windows should be shaded by an overhang or other devices such as awnings, shutters and trellises. If an awning on a south facing window protrudes to half of a window’s height, the sun’s rays will be blocked during the summer, yet will still penetrate into the house during the winter. The sun is low on the horizon during sunrise and sunset, so overhangs on east and west facing windows are not as effective.

The perimeter of the foundation wall or slab should be insulated to the frost line or around the slab perimeter. In a temperate or cold climate, the east and west walls of the sunspace should be insulated (no glass). The precise amount of equator-facing glass and thermal mass should be based on careful consideration of latitude, altitude, climatic conditions, and heating/cooling degree day requirements. 'Low-grade' energy needs, such as space and water heating, have proven over time to be better applications for passive use of solar energy. Objects and materials are placed behind these windows to absorb and retain the incoming heat. The materials used in these surfaces and objects are referred to as thermal mass materials due to their ability to effectively absorb and retain heat.
Passive solar houses in colder areas will use heat-absorbent materials in the building design to maximize natural heat retention. This article will discuss how passive solar homes are designed and provide real examples to outline the benefits of these design strategies in colder climates. In conclusion, sustainable housing trends are reshaping the way we conceive, design and inhabit our living spaces.

The open floor plan across all levels, alongside double-height ceilings, fosters a naturally light and airy atmosphere. This eliminates the need for excessive artificial lighting and air conditioning. Furthermore, the lack of partitions between the ground floor, featuring an open kitchen and bedroom, and the mezzanine master suite, allows for natural ventilation to flow freely throughout the villa. This synergy between design and Indonesia’s tropical climate creates a comfortable and eco-friendly living environment. The shape and size of your roof can also constitute effective passive design. Adding a large overhang allows light into your home during wintertime because the sun is at a higher angle, says Rodriguez.
Thermal chimneys are designed around the fact that warm air rises; they create a warm or hot zone of air (often through solar gain) and have a high exterior exhaust outlet. The hot air exits the building at the high vent, and cooler air is drawn in through a low vent. In the case of the Myers’ house, the available house pad was narrow and long on a north-south axis, so I placed extra glass on the south-facing great room for more solar heat gain.
