Corrugated metal roofing is a good choice for a passive solar house because it deflects much of the sun’s radiant energy while also reducing the heat transferred to the roof surface below. Because of its undulating configuration, little of the material touches the roof, minimizing its heat conductivity. Additionally, if you install a vent ridge cap, air will circulate upward in the furrows, letting heat escape naturally while drawing cooler air under the roofing.

Another major issue for many window systems is that they can be potentially vulnerable sites of excessive thermal gain or heat loss. Infrared thermography color thermal imaging cameras ( used in formal energy audits ) can quickly document the negative thermal impact of roof-angled glass or a skylight on a cold winter night or hot summer day. Some passive systems use a small amount of conventional energy to control dampers, shutters, night insulation, and other devices that enhance solar energy collection, storage, and use, and reduce undesirable heat transfer. Passive solar heating works by allowing light to shine through properly oriented windows.

Three Things to Avoid When Installing Your Solar Panel System
While indirect solar systems use the same primary principals of passive solar design as direct systems, there is one key difference here. Oftentimes, glass is also placed outside of the wall so that it can trap and absorb even more of the sun’s heat. The goal of passive solar heating systems is to capture the sun’s heat within the building’s elements and to release that heat during periods when the sun is absent, while also maintaining a comfortable room temperature.

This allows for sunlight to hit the “front” of the house directly, all year long. The building is then built square along on the East-West line, typically using the same heat transferring materials and orientations throughout. What many people don’t know is that passive solar design can go much deeper than simply installing a few windows and skylights in a home.

Concrete walls (56 tons’ worth in our case) provide a good deal of heat storage capability, but the thought occurred to me that perhaps we could pack away some sun-given warmth in the air path under the floor, as well. Rather than construct an elaborate rock or water storage system, though, we decided to simply use concrete blocks that could double as thermal mass and floor joists. Exposed steel frame and Douglas fir scissor trusses and locally sourced Pennsylvania Bluestone interior and exterior wall cladding.
The architects even repurposed materials from demolished buildings on the site. Passive cooling strategies like strategically placed shutters and a sweeping roof ensure a comfortable environment for artists and visitors alike, reducing reliance on energy-intensive air conditioning. This unique arts hub serves as a model for future projects, demonstrating how innovative design can foster a vibrant artistic community while respecting the environment. For many years, architects took aim at energy loads with a focus on reducing the energy that buildings require for cooling, heating, ventilation, and lighting. Solar design encompassed ideas of light and passive approaches, and more recently, to operational and structural embodied energy.
Passive Solar Design: Adding Insulation and Thermal Mass
Some of the best thermal mass materials to use in designing your passive solar home are concrete, brick, stone, and tile. The first part of designing a passive solar home is to select the best location for its construction. The only thing that you really need to worry about here is the amount of exposure that the southern side of your home will have to the sun. It should be fully exposed to the sun’s rays to ensure that you are maximizing your homes passive solar heating.

If you just put enough windows on the south side of a well-insulated building, it’ll get toasty during even subzero weather. The real challenges in solar design are those of preventing overheating during the day and of keeping the building warm at night. And both heat storage and air circulation are necessary to meet the two goals.
Choose building professionals experienced in energy-efficient house design and construction and work with them to optimize your home’s energy efficiency. If you’re remodeling an existing home, the first step is to have a home energy audit to prioritize the most cost-effective energy efficiency improvements. While most passive solar houses are designed to maximize direct heat gains, indirect gain designs can actually retain heat for longer. The Toy Storey Residence, designed by Wallmakers in Vadakara, North Kerala, exemplifies sustainable architecture through innovative material reuse and bioclimatic design. The house’s facade integrates over 6,200 discarded toys into a CSEB (Compressed Stabilized Earth Block) ‘Toy Jaali’ lattice, transforming plastic waste into a sculptural and insulating element.
Sunspaces should not be confused with greenhouses, which are designed to grow plants. Sunspaces serve three main functions -- they provide auxiliary heat, a sunny space to grow plants, and a pleasant living area. The design considerations for these three functions are very different, and accommodating all three functions requires compromises. This is an example of a simple Trombe wall designed to transfer solar energy into your house. Since daylight hours are reduced in the winter, more windows help the house heat up faster, like a greenhouse.
Thermal insulation or superinsulation (type, placement and amount) reduces unwanted leakage of heat.[10] Some passive buildings are actually constructed of insulation. Trying to determine the best solar panels for your home is like trying to determine the best car – there’s no one correct answer. Homeowners who are considering solar typically overlook the manufacturer of their solar panels, despite this being one of the most important factors for the longevity... Solar photovoltaic panels are created to absorb the sun’s energy and convert it to usable AC energy in your home. You’ve probably come across them in your research, and you’re wondering which will...

In a direct gain design, sunlight enters the house through south-facing windows and strikes masonry floors and/or walls, which absorb and store the solar heat. As the room cools during the night, the thermal mass releases heat into the house. Ultra-efficient homes combine state-of-the-art energy-efficient construction, appliances, and lighting with commercially available renewable energy systems, such as solar water heating and solar electricity. By taking advantage of local climate and site conditions, designers can often also incorporate passive solar heating and cooling and energy-efficient landscaping strategies. The intent is to reduce home energy use as cost-effectively as possible, and then meet the reduced load with on-site renewable energy systems.
