Viability of naturally ventilated buildings in the UK under predicted future summer climates
… serious implications for overheating of naturally ventilated office buildings, many of which already fail to perform under current heatwave conditions. This thesis addresses the summer performance of such buildings under current and future climates by means of building performance …

Recommendations for the analysis and design of naturally ventilated buildings in urban areas
The motivation behind this work was to obtain a better understanding of how a building's natural ventilation potential is affected by the complexities introduced by the urban environment. To this end, we have derived in detail the physical principles of wind- and buoyancy-driven natural ventilation …

Beyond blue and red arrows : optimizing natural ventilation in large buildings
… has expanded the complexities of producing large naturally ventilated buildings. While it may be argued that designing for natural ventilation is a straightforward, intuitive process, somewhere between the simple diagrams and signing off on the building, the designer must be able to verify that …

Methodology for the evaluation of natural ventilation in buildings using a reduced-scale air model
Commercial office buildings predominantly are designed to be ventilated and cooled using mechanical systems. In temperate climates, passive ventilation and cooling techniques can be utilized to reduce energy consumption while maintaining occupant comfort using natural ventilation. However, current …

Analysis of buoyancy driven airflow patterns in a model of a naturally ventilated building
… help us understand the climate conditions inside naturally ventilated buildings in order to improve the efficiency of the design. Naturally ventilated buildings use temperature gradients to create buoyancy forces in the space and drive the airflow pathways in the space. One architectural design …

Improving the Fanger model's thermal comfort predictions for naturally ventilated spaces
… to improve its thermal comfort predictions for naturally ventilated spaces. A sensitivity analysis revealed that the comfort temperature prediction is by far most sensitive to the comfort value of mean skin temperature. Furthermore, the sensitivity analysis also indicated that for the Fanger …

Beyond arrows: energy performance of a new, naturally ventilated, double-skin facade configuration for a high-rise office building in Chicago
… tend to rely on their intuition when designing naturally ventilated buildings without detailed analyses for the long term. It may be argued that for many standard and smaller buildings, designing for natural ventilation is straightforward: a simple process of drawing diagrams to illustrate how …

Modeling buoyancy-driven airflow in ventilation shafts
Naturally ventilated buildings can significantly reduce the required energy for cooling and ventilating buildings by drawing in outdoor air using non-mechanical forces. Buoyancy-driven systems are common in naturally ventilated commercial buildings because of their reliable performance in …

Thermal Comfort and Spatial Variability: A Study of Traditional Courtyard Houses in the Hot Dry Climate of Khartoum, Sudan
… on energy consumption in air-conditioned buildings. Examining occupants' space-use patterns revealed that people were going about their daily life inside traditional houses in a manner that ensured low levels of thermal discomfort. However, a range of social, functional and cultural …

Study of natural ventilation design by integrating the multi-zone model with CFD simulation
… the performance of natural ventilation in whole buildings, as well as the detailed thermal environmental information in some particular space. This work has coupled the multi-zone airflow model with the thermal model. A new program, called MultiVent, has been developed with a web-server that can …

Study and prediction of the energy interactions between buildings and the urban climate
… can have an impact on the energy consumption of buildings, especially residential and naturally ventilated buildings. At the same time, the energy performance of buildings can affect outdoor air temperatures, mainly through the waste heat emissions from outdoor air-conditioning equipment. …

The effect of atrium configurations on energy usage in high-rise office buildings in semi-arid climate of Tehran
… around 33% of energy is used by HVAC systems in buildings (Salib & Wood, 2013). As a passive design element, an atrium has the potential to naturally provide heating and cooling, as well as adequate daylight, in arid and temperate climates. Moreover, a naturally ventilated atrium has also proven …
