Factors affecting natural ventilation
WebAug 2, 2016 · Consider the use of fan-assisted cooling strategies. Ceiling and whole-building fans can provide up to 9°F effective temperature drop at one tenth the electrical energy consumption of mechanical air-conditioning systems. Determine if the building will benefit from an open- or closed-building ventilation approach. WebIn rooms with natural ventilation, low-frequency noise and total sound-pressure levels were lower; however, the rooms had higher ultrafine-particulate counts and lower ventilation rates.

The results showed that the factors that most influenced the performance of broilers were temperature , ventilation rate, and genetic strain .(AU)
WebSome key considerations when designing for thermal comfort: Ideal internal temperatures in winter: 18-21˚C. Ideal internal temperatures in summer: 22-27˚C. Occupants can experience thermal discomfort when the temperature at foot level is below 19˚C, or 3˚C below head level. This can be alleviated with underfloor heating. WebStack ventilation uses this natural phenomenon to our advantage by allowing us to control air flow without the use of expensive mechanical systems. From open windows that pull …
