Thermal comfort for naturally ventilated residential buildings in Harbin. The neutral temperature in Harbin is lower than neutral temperatures in warm climates by others, which is in accordance with the thermal adaptive model.
80% of the occupants can accept the air temperature range of – °C, which is wider than the summer Cited by: Predicted thermal acceptance in naturally ventilated office buildings with double skin façades under Brazilian climates The methodology and the results developed from this study enable initial assessment of application of DSF in naturally ventilated buildings under warm and hot climates.
This indicates that for climates with mild Cited by: 8. Dec 12, · Preferred temperatures were °C and °C in naturally ventilated and air-conditioned buildings, respectively, both of which were °C cooler than neutral temperatures.
This result suggests that people of hot climates may use words like Cited by: This paper presents a thermal comfort study in a naturally ventilated residential building located in a tropical hot-humid climate region. The specific This paper presents a thermal comfort study in a naturally ventilated residential house located in a variation between day and night temperatures, that is only from 25 to 32OC (77 to 90°F).
Natural Ventilation and Colour in Hot Climates How buildings heat up when not ventilated. In a hot climate, the cost to air condition the entire volume of a large building is often prohibitive, and without some precautions a building quickly heats up during the day via radiant heat and heat conduction.
A thermal comfort field study has been carried out in five cities in the humid subtropical climate zone in China. The survey was performed in naturally ventilated and air-conditioned buildings.
Sustainable roofs for warm humid climates -a case study in residential buildings in Madurai, Tamilnadu, India naturally ventilated residential buildings in warm humid climates of India.
In hot and humid climates, for those that can afford it, air conditioning is a standard requirement and designers generally intend their buildings to include some sort of mechanical cooling system. However, providingthermal comfort in naturally ventilated buildings in this climate is a big challenge.
Vented and Sealed Attics in Hot Climates Research Report - Armin Rudd and Joseph Lstiburek Abstract: Sealed attic construction, by excluding vents to the exterior, can be a good way to exclude moisture- laden outside air from attic and may offer a more easily constructed alternative for air leakage control at the top of residential.
conditioned buildings, and 31°C in naturally ventilated buildings. The upper limit of comfortable temperature, which was developed for the 40°N latitude, can be K higher for every 12 degrees change in latitude to the south . Since Bangkok is located at 14°N latitude, the corresponding comfort temperature upper limit is °C.
Museum Passive Buildings in Warm, Humid Climates By Franciza Toledo Introduction Old and new buildings can be climate-responsive and able to attenuate exterior conditions. Historic buildings, in particular, were conceived to deal with climate passively, through proper design and adequate building features and materials.
At one time, all buildings were naturally ventilated, and many surviving examples provide hints about what strategies are effective in certain climates. Old buildings had articulated plans and courtyards to provide windows in each room; some buildings had more complicated and ingenious features.

Thermal mass for limiting summertime overheating. Thermal mass is ideally placed within a building where it is shielded from direct solar gain but exposed to the building occupants. It is therefore most commonly associated with solid concrete floor slabs in naturally ventilated or low-energy mechanically ventilated buildings where the concrete soffit is left exposed to the occupied space.
Careful selection of building shape and orientation are primary elements in the design of naturally ventilated buildings in Warm/Hot + Wet (Humid) climates. Building orientation will determine the intensity of solar radiation falling on the walls and roof of the building, and the ventilative effectiveness of the building openings.
3 Moisture control and ventilation. Olli Seppänen and the prevalence of such symptoms was higher in air-conditioned than in naturally ventilated buildings, independent of humidity. As cold air contains less absolute humidity than warm air, humidity removal is most effective at low outdoor temperatures.
In hot climates, the outdoor Cited by: 8. Jan 12, · This review article has attempted to track significant developments in our understanding of the thermal comfort issues in air-conditioned office and educational buildings in hot and humid climates in the last 25 years, primarily on occupant preference for thermal comfort in such climates.
operative temperatures below thermal neutrality for all climates. In the hot –humid climate, a lower comfort limit was not observed for naturally vent ilated buildings, and the adaptive equation was inﬂuenced by indoor air speed rather than indoor relative humidity.
The new equation developed in this. NATURAL VENTILATION FOR OFFICE BUILDINGS IN WARM demonstrated that users of naturally ventilated buildings are comfortable in a wider range of temperatures than users of buildings with centrally controlled HVAC systems.
The data in ASHRAE (RP) from (Brager et al. ) show that users with. In warm climates where houses are naturally ventilated, these temperature differentials (either 5 or 10°C) cannot be achieved for much of the year, and there may be no mechanical heating/cooling appliance to precool or heat the home for testing purposes (because the homes are passively heated/cooled).
