Passive Solar House Plans Hot Climate
In most climates an overhang or other devices such as awnings shutters and trellises will be necessary to block summer solar heat gain. Careful sealing with tape for air-tightness jaw dropping amounts of insulation and a fresh air intake and heat exchange system designed from scratch spawning a company that still exists.

Designers use the Passive House Planning Package PHPP to optimise the building for the local climate conditions.
Passive solar house plans hot climate. These homes require much less fossil fuel energy to. Windows glazing facing the south with some sort of control thermal mass insulation along with the ability to harness naturally occurring convective air currents for cooling the house in the summer. Zero Energy Design has been doing it for decades.
Passive cooling strategies 4. Passive solar design begins with the simple idea that you can build a house that uses natural heating cooling ventilation and daylighting. Superinsulation and Passive House came out of cold climates.
It was no solar hippie house. Ecohome June 5 2012 Last updated. Its just passive strategies natural strategies for keeping the home cool without the use of machinery or electricity.
The Saskatchewan House in the 1970s for example. Sustainable design passive solar house plans can ultimately function without any mechanical devices controlling indoor climate. Capabilities of WUFI Passive static.
If you are considering passive solar design for a new home or a major. Landscaping can also help keep your passive solar home comfortable during the cooling season. What is the real difference between solar passive homes and passive house homes.
Its condensation in winter from indoor humidity thats the problem. Active cooling strategies 5. Materials such as painted metal with high emissivity release heat more rapidly to the atmosphere cool off at night than low emissivity materials eg.
A passive solar house requires careful design and siting which vary by local climate conditions. By Larry Hartweg ZEDmaster. This is a very hot climate and yet our earthbag roundhouse is about 15 degrees Fahrenheit cooler inside than out.
Passive solar heating is the least expensive way to heat your home. Put simply design for passive solar heating keeps out summer sun and lets in winter sun while ensuring that the building envelope keeps that heat inside in winter and allows any built up heat to escape in summer. The priority should always be pas.
A passive solar home plan will depend on the location of the homewhether thats in a predominantly cool area such as the northeast section of the US or predominantly hot area such as the southwest section of the US. Passive House is the worlds most energy efficient standard and its the one we promote it really doesnt cost much more at all to build to this standard and reap the benefits including much lower running costs. So 15 degrees Fahrenheit 8 degrees Celsius temperature difference with no mechanical cooling systems.
ENERGY STAR labeled roofings have a solar reflectance of at least 25 for steep sloped roofs. For optimal performance in a hot climate choose a roofing with a high solar reflectance 50 and a high emissivity 80. These passive solar strategies have been used around the world for centuries and it is only in the past 60 years since the advent of mechanical heating and air conditioning systems that we have become dependent on artificial temperature control and abandoned common sense low.
No air conditioners no fans no anything. There are a few traits that work together to make a passive solar home efficient. Humidity is a concern there but for a different reason.
Passive design for heating cooling and daylighting can and should be incorporated into buildings in all climates. Drivers of sensible and latent cooling loads 3. The result was the worlds first Passivhaus - The Saskatchewan Conservation House which not only incorporated passive heating from the sun but also many of the elements that make up the current Passive House standard.
Basic solar science can be used to keep your home cool without electric bills. In summer months passive solar homes in North Carolina must compensate for the hot humid climate and the large amount of heat that can come into the home through windows. With Passive House in hot-humid or mixed-humid climates its indoor and outdoor humidity that can bite.
We do however also offer a Code Plus version of our house plansSlightly less efficient than Passive Code Plus is perfect for a small urban. With a southern orientation and well placed windows passive solar homes can potentially reduce heating requirements by an easy 25 without adding any cost by designing around a good Passive Solar Index score. Not only the passive aspects of this house are impressive but its active systems are something that others interested in off.
The true challenge of passive solar design is to ensure low summer cooling bills compared to those of. The huge thermal mass acts as a giant battery constantly recharging with direct solar energy gain brought in through the windows and using the same moderating thermal mass effect to cool in the summer. For high summer comfort this means understanding the solar loads and the ventilation strategy to ensure that temperatures inside the building do not exceed 25 C for more than 10 of hours annually.
