Ventilation devices for roof spaces conventionally comprise a pipe which passes through the roof ridge and is covered by a wind-protection cap. Said devices detract from the aesthetic appearance of the roof and are susceptible to disruption in strong winds. The object of the invention is to ...
In one aspect primary vents are installed in the roof deck below the roof tiles, and the roof tiles are mounted to as to provide air spaces in between them and thus allow air flow from the primary vents to the outside. In another aspect a secondary vent is constructed to look like the...
And while automation has noticeably improved the quality of interior spaces with solutions like purified air and temperature control, nothing compares to the natural cool breeze of mother nature. But just like everything else in architecture, there is no one size fits all; what works in Tanzania...
HVAC system designers typically take IT equipment into account, modeling it as a heat source of from 0.4 to 1.1 W/ft2, with an average value of approximately 0.8 W/ft2. Naturally, some spaces, such as computer rooms, can generate much higher local loads, as do the portions of data cente...
Description: Can be used for the ventilation of roof structures and attic spaces, as well as sewer pipes. Designed for plain standing seam or, if retrofitted, felt roofing. Contains a valve, pass-through, underlay ring and fixing screws, as well as a thick rubber seal on the bottom of th...
Performance Evaluation of a Wall Mounted Convector for Pre-heating Naturally Ventilated Spaces There is a growing desire to reduce peak temperatures within non–domestic buildings by accessing the thermal mass of separating floors. These floors are t... SOC Managementengineering,The University of Readin...
The flow rates through the street openings and the street roofs, along the street networks evaluate the amount of external air entering and flowing through the urban airspaces. The air change rate (ACH) for a given urban airspace assesses the relative amount of the air exchange between this ...
Identify and cure sources of crawl space moisture, such as roof drainage spilling around the foundation. In roughly 90 % of inspections performed by experts, we find that wet or moldy crawl spaces or basements that had been blamed on "high water table", "rising damp", or "built over a...
Also known as attic and crawl space ventilation. Crawl spaces need to be protected from moisture that can lead to mold and bacteria growth. Moisture in a crawl space can also lead to structural damage. Installation ofintake and exhaust ventsis essential to ventilate the roof and the attic. ...
A flashing assembly for use where a sloping roof (22) extends away from a wall (10) is a strip (28) of flexible flashing material (e.g. lead) bearing a layer of air permeable material (30), preferably fibrous or reticulated foam material. This spaces the strip (28) from the roof (...
