Stack Ventilation as A Design Tool to Improve Indoor Thermal Comfort of Duplex Studio at Soho High Rise in Hot and Humid Climate

Abstract

Natural ventilation can afford building occupants with thermal comfort and a healthy indoor environment. Ventilation approach (i.e. cross ventilation, stack ventilation, single-sided) is conceivably the key parameter that influences ventilation performance among all the design-related parameters. To improved energy and indoor air quality issues, the ventilation approach should be smarter and sensible. A significant smart and sensible ventilation concept is to enhance natural ventilation. Natural ventilation, that is dependable factors with the principles of sustainability and green energy, is widely acknowledged nowadays. Residential and Commercial office building of all major metropolitan cities of the world is characterized by high rise and high density. In this respect, this paper investigates the performance of a representative SOHO high rise building in the city of Selangor, Malaysia and evaluates the optimum solutions by using an optimization approach for that SOHO high rise. The study focused on a unit with single-sided ventilation (i.e. openings in just one external wall) and for stack ventilation only openings are the doors from the upper level and lower level. This pilot test will assess that air movement through the doors can improve indoor thermal comfort. A selection of unit is grounded on the orientation and mid-floor level of the building. The effects will demonstrate the amount of wind velocity passing through the doors can decrease the temperature from 32? to 30.3? and RH from 62.6% to 68.5%.
