“…However, studies such as [5,6,19,[32][33][34][35][36][37][38] have shown that poor acoustic performance can have negative impacts on health, behaviour, and cognitive function of a person. This view was shared by [39] who found that acoustic comfort in a building has a crucial impact on the health, well-being, communication, and productivity of the occupants, and can be affected by factors such as the geometry and volume of a space, generation of sound within or outside the space, airborne noise transmission, impact noise, and the acoustic characteristics (absorption, transmission, and reflection of sound) of the interior surfaces. Yet, acoustics has been neglected in design and construction practice in Nigeria despite of the provisions of section 6.2.11 of the National Building Code (NBC) 2006 [40].…”

This study assessed the acoustical performance of residential buildings in Awka, Anambra State to determine the level of satisfactions of the occupants. The study surveyed the residential buildings and distributed questionnaires to the users and occupiers of different classes of residential buildings. The results of the survey were analysed using Means Satisfaction Index (MSI) and Relative Performance Index (RPI) to assess the level of satisfaction of the occupants of the buildings and the acoustical performance of the buildings respectively based on 12 selected acoustic performance criteria. It further used Pearson Product Moment Correlation to establish the relationship between occupants’ level of satisfaction and acoustic performance of the buildings. The study found that the overall acoustic performance of the buildings was grossly poor and unsatisfactory with average RPI of 0.35. It also found that the residents were very dissatisfied with the acoustic performance of the buildings in which they live (average MSI =1.74). The study further found that there was significant positive relationship between the occupants’ level of satisfaction and acoustic performance of the buildings with a Coefficient Correlation (r) of 0.875 and a computed t-test value of 5.708 which is greater than the critical t- value (2.228) tested at 5% significance level. The Coefficient of Determination (R2 = 0.7567) then suggested that about 75.69% level of satisfaction of the occupants of the residential buildings in Awka could be triggered by the acoustic performance of the buildings in which they live. On this evidence, the study craves for the enforcement of the provisions of the National Building Code as regards to sound control in buildings. In addition, there is need for adoption of different strategies for improving acoustics performance of buildings such as absorption, mechanical decoupling, mechanical damping, blocking, covering, etc., so as to promote good acoustic practices that would improve sustainable performance of our buildings and decline the resulting consequences of sounds in our residential buildings.

“…Indoor environmental quality (IEQ) is an indicator of the general quality conditions of indoor environments that may have an impact on human's health. The IEQ indicator is composed of multiple subdomains [94], including air quality, lighting quality, noise levels, thermal comfort, among others. This section aims to address the most important IEQ factors and how their monitoring and control can be achieved.…”

Healthcare optimization has become increasingly important in the current era, where numerous challenges are posed by population ageing phenomena and the demand for higher quality of the healthcare services. The implementation of Internet of Things (IoT) in the healthcare ecosystem has been one of the best solutions to address these challenges and therefore to prevent and diagnose possible health impairments in people. The remote monitoring of environmental parameters and how they can cause or mediate any disease, and the monitoring of human daily activities and physiological parameters are among the vast applications of IoT in healthcare, which has brought extensive attention of academia and industry. Assisted and smart tailored environments are possible with the implementation of such technologies that bring personal healthcare to any individual, while living in their preferred environments. In this paper we address several requirements for the development of such environments, namely the deployment of physiological signs monitoring systems, daily activity recognition techniques, as well as indoor air quality monitoring solutions. The machine learning methods that are most used in the literature for activity recognition and body motion analysis are also referred. Furthermore, the importance of physical and cognitive training of the elderly population through the implementation of exergames and immersive environments is also addressed.

“…It concerns the achievement of different human comfort needs within the building's internal spaces, including the quality of indoor air, ventilation rate, thermal comfort, visual comfort, acoustical comfort, physiological comfort, drinking water, and other different human needs that should be achieved, and the reduction of ergonomics, micro-organisms, Hygiene, odors, electromagnetic radiation, and other pollutants. Achieving these human needs is a major role of buildings, as people spend about 90% of their lives within buildings, which makes the quality of the indoor environment affect the human directly, for whom the buildings are mainly constructed [12,32,33]. However, the awareness of green buildings demand is increasing, ensuring the desired level of IEQ is often not given the worthy care, and buildings rated as 'green' do not guaranty their cope with the desired IEQ level, especially if given an approximately low assessment weigh in the EBRSs, such as in LEED and BREEAM, which presents only around 14.6% and 15% of its total weight sequentially [4,31].…”

“…It is proposed to modify this item in the C version, by adding some types of views that can be achieved through the windows, to ensure that the achieved views through the buildings avoid the obscuring high lands in Taif, as well as to take advantage of the amazing scenery of Taif's nature. Some types of views that are mentioned in the LEED v4 could be helpful, such as: 'multiple lines of sight to vision glazing in different directions at least 90 degrees apart, views that include at least two of the following: (1) flora, fauna, or sky; (2) movement; and (3) objects at least 7.5 m from the exterior of the glazing; and unobstructed views located within the distance of three times the head height of the vision glazing' [32].…”

“…Besides, providing automatic indication devices on all-natural ventilation openings meant to achieve the minimum opening requirements. An alarm must work when any of the openings are closed during occupied hours [32]. Natural ventilation has a special significance in Taif due to its high altitude and its moisture and biological characteristics, which increases the occurrence of some serious health problems, such as respiratory symptoms, allergies, asthma, and perturbation of the immunological system, as previously discussed [31].…”

Adjustment of the Indoor Environmental Quality Assessment Field for Taif City-Saudi Arabia

et al. 2020

Along with the global concern of the Environmental Assessment of Buildings, the Kingdom of Saudi Arabia (KSA) had recently used its system, Mostadam, to provide a suitable method to assess its buildings environmentally. Nevertheless, Mostadam still cannot be used for all Saudi Arabia regions without having misleading results, which is due to its various internal regions with their various characteristics. Taif city has its unique environmental characteristics, which affect all the environmental buildings’ assessment fields. This research aimed to adjust the Indoor Environmental Quality (IEQ) field of Mostadam according to Taif characteristics. The research analyzed Taif characteristics that have an impact on the IEQ field, which are mainly related to the occupants’ different comfort needs and health requirements. Then, according to an analytical methods, authors proposed some changes to adjust Mostadam IEQ field according to these characteristics. The research resulted in an obvious difference between the resulted IEQ items weights and formulation versus the origin one of Mostadam, which proves the need for such adjustment to achieve a fair and trusted assessment to achieve the utmost credible assessment results when assessing buildings environmentally in Taif. It is recommended to adjust other assessment fields similarly later on, and then globally.
