An attic fan installed underneath a roof. A powered attic ventilator, or attic fan, is a ventilation fan that regulates the heat level of a building's attic by exhausting hot air. A thermostat is used to automatically turn the fan off and on, while sometimes a manual switch is used. An attic fan can be gable mounted or roof mounted. Additional ...
The application of trickle vents in naturally-ventilated spaces can help contribute to IEQ Credit 2 under the LEED green building rating system. LEED EA Credit 2 references CIBSE Applications Manual 10, which provides advice on the design of naturally-ventilated spaces, recommending the installation of trickle vents in naturally-ventilated spaces.
Solar air heating is a solar thermal technology in which the energy from the sun, insolation, is captured by an absorbing medium and used to heat air. [1] Solar air heating is a renewable energy heating technology used to heat or condition air for buildings or process heat applications. It is typically the most cost-effective out of all the ...
An axial belt-drive exhaust fan serving an underground car park. This exhaust fan's operation is interlocked with the concentration of contaminants emitted by internal combustion engines. Mechanical ventilation of buildings and structures can be achieved by the use of the following techniques: Whole-house ventilation; Mixing ventilation
The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non-water heating devices such as solar cookers or solar air heaters. [1] Solar thermal collectors are either non-concentrating or concentrating.
