“…Moreover, the reliable datasets from those operating buildings, describing their structural and environmental performance, have provided essential support for the generation and calibration of structural/environmental numerical building models in order to optimise building designs and develop cost- [58], [59] or the properties of the novel forms of building systems [44], [47], [56], [57], [60], [62]. …”

“…The topics range from the utilisation of concrete structural elements' properties to minimise the energy usage in buildings [54], through to the investigation of the real-time control strategies in smart buildings [55], to analysis of time dependent effects of concrete systems [56] and determining optimum retrofitting solutions of concrete structural elements [57]. Moreover, the EB realtime data have formed a strong basis for the ongoing research projects, such as the generation of calibrated numerical models (see, for example, Figure 11) that (i) investigate the building's energy/ventilation performance and their influence on the occupants thermal comfort [58]- [60] and (ii) investigate the structural performance of novel hybrid precast and in situ reinforced concrete systems [47]. The ILAS building is mainly built in the precast concrete technology [61], including the building frame, twinwall system, lattice (also known as filigree slabs) and hollowcore slabs.…”

“…Thus, CFD empowers building designers to optimize the building solutions by simulation instead of trial-and-error techniques that require much effort, time and resources. Moreover, several standards and guidelines [11][12][13][14][15] have been developed to assist designers in the CFD model definition. The current research is therefore based on CFD to assist building designers to optimize NV building behaviour.…”

Environmental awareness has led to an increased concern about low carbon technologies implementation. Among these technologies, the following research is focused on the natural ventilation effect evaluation in buildings prior to its construction. The aim is to select the most suitable architectural solution to ensure comfortable indoor environment in the most efficient way in the early building design stage. The design approach takes into account the wind conditions in the region and the building surroundings to evaluate the façade opening distribution impact on natural ventilation performance. The design approach is based on computational fluid dynamics (CFD). In this article, a case study located in the Valencian Community (Spain) is depicted. The Valencian Community coastal climatic conditions are evaluated to assess the low carbon technology energy saving potential. Moreover, the main drivers and barriers involved in the design approach implementation in the region are discussed. The conclusions show that the natural ventilation design approach can improve up to 9.7% the building energy performance respect an initial building design, in which natural ventilation has not been considered. The results contribute to an assessment of the complete low carbon technology effect in the region.

“…This governing equation is solved using ANSYS CFX 14.5. This software is well-accepted software that has been used by many researchers on multi-storey buildings [32,[39][40][41]. For domain set up, the blockage ratio for the CFD model is set at 1.67% to avoid blockage effect as recommended by previous studies [10,32,36].…”

The Effects of Void on Natural Ventilation Performance in Multi-Storey Housing

Abstract:Enhancing natural ventilation performance in multi-storey housing is very important for the living environment in terms of health and thermal comfort purposes. One of the most important design strategies to enhance natural ventilation in multi-storey housing is through the provision of voids. A void is a passive architectural feature, which is located in the middle of deep plan buildings. It is very crucial to consider the configurations of voids in the buildings for enhancing natural ventilation, especially for multi-storey housing. In this study, Malaysian Medium Cost Multi-Storey Housing (MMCMSH), which is an example of multi-storey housing located in a suburban area, has been selected in this study. This study aims to investigate the potential of void for enhancing natural ventilation performance in multi-storey housing by the comparison of two different void configurations. Field measurement of MMCMSH has been conducted to validate Computational Fluid Dynamic (CFD) model and Atmospheric Boundary Layer (ABL) is an important parameter for setting up the CFD Model's domain. Ventilation rate (Q), which is necessary for comfort and health reasons, is an important parameter for the comparison of the different void configurations. This study revealed that the provision of void can enhance natural ventilation performance in multi-storey housing with an increase in the value of Q, from 3.44% to 40.07%, by enlarging the void's width by 50% compared to the existing void.
