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. [1]
When it comes to keeping plants warm this winter, a little preparation can go a long way. Give plants a layer of protection by mulching and watering as needed. Be familiar with the plants in your ...
A well constructed igloo can keep an average temperature of 16 °C (61 °F) if heated internally only by body heat. [2] However, if the blocks are too thick, they can cause excessive heating and risk melting. Several factors affect the thermal characteristics of igloos, including snow conditions, igloo size, structure, and arrangement.
Cooling is typically done by opening windows in the greenhouse when it gets too warm for the plants inside it. This can be done manually, or in an automated manner. Window actuators can open windows due to temperature difference or can be opened by electronic controllers. Electronic controllers are often used to monitor the temperature and ...
Stirrup sample. Stirrups form the outer part of a rebar cage. The function of stirrups (often referred to as 'reinforcing steel links' and 'shear links') is threefold: to give the main reinforcement bars structure, to maintain a correct level of concrete cover, and to maintain an equal transferance of force throughout the supporting elements.

Sunroofs can be manually operated or motor driven, and are available in many shapes, sizes and styles. While the term "sunroof" is now used generically to describe any moveable panel in the roof, the term "moonroof" was historically used to describe stationary glass panes rigidly mounted in the roof panel over the passenger compartment.
