In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.
The passivhaus standard combines superinsulation with other techniques and technologies to achieve ultra-low energy use.. Superinsulation is an approach to building design, construction, and retrofitting that dramatically reduces heat loss (and gain) by using much higher insulation levels and airtightness than average.
Parabolic Solar Cooker. A solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize drink and other food materials. Many solar cookers currently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves, [1] and advanced, large scale solar cookers can cook for hundreds of people.

Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. [1] Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
Solar Cookers International spearheads the solar cooker Performance Evaluation Process (PEP). The PEP testing program is an objective, scientific process to evaluate solar cooker performance. Evaluation of the performance, user experience, and quality of solar cookers was identified as a high priority by the attendees of the 5th SCI World ...
Solar-Powered Greenhouse Imagine harnessing the sun’s energy to power your greenhouse. With solar panels, you can power lights, fans, and heaters without the hefty energy bills.
Installed faced fiberglass batt insulation with its R-value visible (R-21) [1]. The R-value is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive [2] flow of heat, in the context of construction. [3]
No, heated outdoor cat houses are designed to be energy-efficient. Most use low-wattage heating pads, typically consuming between 10 to 40 watts — about the same as a small light bulb.
