Storage occupancies - The heat release rate from high piled storage commodities is expected to be very high. In such cases, it is considered by some fire protection professionals desirable to vent the heat from the building if the temperatures in the building reaches sufficiently high levels to endanger the structural stability of the roof system.
Wood is a poor insulator and so it conducts heat from the radiant barrier to lower surfaces of said wood, where it, in turn, sheds heat by emitting IR radiation. According to the US Department of Energy, “Reflective insulation and radiant barrier products must have an air space adjacent to the reflective material to be effective.” [9]
Air sealing can improve the energy efficiency of a building by minimizing the amount of energy needed to heat or cool the building. This is especially pertinent in cold-climate buildings where space heating consumes the largest amount of energy. [9] A blower door test can be used to test the quality of the air sealing of the building envelope.
Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process. [7]
In a modern high-rise building with a well-sealed envelope, the stack effect can create significant pressure differences that must be given design consideration and may need to be addressed with mechanical ventilation. Stairwells, shafts, elevators, and the like, tend to contribute to the stack effect, while interior partitions, floors, and ...
Vinyl-sided, wood-framed sheds blend the strength of a wood frame with the maintenance-free aspect of vinyl siding (it does not need to be painted or varnished). The International Building Code (IBC) defines a shed as a building or structure of an accessory character; it classifies them under utility and miscellaneous group U (Chapter 3 Section ...

Mechanical ventilation is often provided by equipment that is also used to heat and cool a space. Natural ventilation is the intentional passive flow of outdoor air into a building through planned openings (such as louvers, doors, and windows). Natural ventilation does not require mechanical systems to move outdoor air.
