The openings for natural ventilation
are automatically regulated to adjust zone air temperature to be close to the lower limit temperature.
According to the results, the sows which received cooled ventilation presented a higher estimated yield of milk and smaller weaning-estrus interval compared to those under natural ventilation
, being also observed a smaller weaning-estrus interval for first parturition sows.
We conducted a survey on designers, managers, and owners of 72 natural ventilation
buildings selected from Japanese literature.
Cool nighttime air is common in the warmer seasons, and this increases the time the mechanical systems can stay off even on days when the ambient conditions exceed those suitable for natural ventilation
In Singapore, Ng Teng Fong General Hospital and Jurong Community Hospital incorporate operable windows and a unique fan-shaped ward layout so that more than 80 percent of the inpatient areas receive natural ventilation
. (For more on the project, read "Breath of Fresh Air" on page 38.) In awarding the project a 2017 AIA COTE Top Ten Award by the American Institute of Architects Committee on the Environment (COTE), the awards jury noted that its passive design strategies are a model for hospitals around the world.
The distinctive wood carvings on the natural ventilation
panels would clearly describe the masters' knowledge on the disciplines of art, mathematics, nature and religion.
To achieve natural ventilation
, the maximum ratio of floor depth to ceiling height must be considered and the heat gains to be dissipated which determine the total area of the opening.
The Moffitt line of natural ventilation
products provides facilities with a ventilation solution that requires zero operating costs and zero maintenance costs, while still resulting in cooler and more comfortable buildings.
Coffee processing simulations were performed in two situations: fully enclosed or without natural ventilation
(PHP_unventilated), and with the openings of the perforated brick or naturally ventilated (PHP_ventilated).
"Switching to high-performance operable windows can be a cost-effective way to introduce natural ventilation
into occupied spaces and improve overall energy efficiency."
The in vitro cultivation methods consisted of the conventional micropropagation (liquid, solid with 5 or 6g [L.sup.-1] of agar), micropropagation in natural ventilation
system (liquid, solid with 5 or 6g [L.sup.-1] of agar) and micropropagation in bioreactors of continuous and temporary immersion, totalizing eight treatments.
Trees were left in place on the site to create an outdoor woodland classroom and a computer-controlled natural ventilation
system uses sensors to monitor wind speed and direction and carbon dioxide levels in rooms, which in turn alters the position of power-operated windows in the rooms accordingly.
