“…In the 1980s and 1990s, several researchers contributed to the psychrometric chart and applied unique comfort models [24]. More recently, several researchers applied the psychrometric chart to local contexts [25][26][27][28]. The chart of Olgyay has been used less because it is less comprehensive.…”

A B S T R A C TThe energy consumption and thermal comfort in buildings are heavily affected by weather conditions. Therefore, the aim of this paper is to analyze the bioclimatic potential of Algerian climate zones. This analysis was made based on eight representative locations using recent weather datasets (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017). The thermal comfort and passive design potential analysis were based on a psychometric chart applying the adaptive comfort model ASHRAE 55-2017. In addition, an evaluation of the bioclimatic potential was conducted using simulations of a monitored and calibrated residential building model in Algeria using EnergyPlus. The building model has been tested in eight previously selected locations. The heating and cooling energy load results were calculated for each climatic zone and compared. The results allow architects and urban planners to better understand the climate and provide practical design guidance.1 Evaluate the thermal comfort and bioclimatic design potential of eight selected cities, which represent the six official climate zones of Algeria, based on a psychometric chart and the adaptive comfort model ASHRAE 55-2017. 2 Validate the bioclimatic potential analysis by simulating the heating https://doi.

“…These tools are based on their own indicators. The literature proposes many bioclimatic indicators that are focused on the improvement of thermal comfort mostly through natural ventilation [35][36][37][38][39][40][41][42][43][44][45][46][47]. It also proposes building performance indicators, but they are mostly component-based [48][49][50][51].…”

The current challenge is to reduce the building energy consumption, in hot and humid climates, for which air conditioning is widespread. Up to now, the lack of criteria that identify the available cooling resources and the level of performance of technical solution has represented the major obstacle. To address these issues, the authors propose a new set of indicators to fully inform the decision-making process of the bioclimatic design of fully space-conditioned buildings in a hot and humid climate. This set of indicators provides an overview of the exploitable environmental resource (external air through external convection, natural ventilation and sky radiation cooling) referred as the Environmental Resource Indicators and of the capacity of the building to exploit those resources referred as the Building Performance Indicators. The indicators are implemented for a very basic two-story residential building in the hot, humid climate of Djibouti. The case study shows not only the ability of the indicators to reflect the bioclimatic performances of the buildings but also their ability to give an overview of the building heat exchanges, from which the implication of improper bioclimatic solutions on building cooling consumptions can easily be identified. These indicators are a means to help choose which technical solutions are most suited to the local climate, which is very useful for designers and architects in the early stages of building design.

“…In literature and worldwide market, numerous arrangements and designing of evaporative cooling systems are available. However, upcoming three headings are important from the subject of thermodynamic conception, that is, isenthalpic cooling [46,47], sensible cooling, and dew-point (or below wet-bulb) cooling [10,48,49]. In order to highlight the significance of temporal and spatial variations on AC performance, 24 h-based ambient air conditions of two cities, that is, Multan (Pakistan) and Fukuoka (Japan), are investigated for nonhuman AC applications.…”

“…Direct evaporative cooling [46,49] (DEC) is the fundamental sense of typical evaporative cooling conception in which water vapors continuously evaporate into air until condition of air saturation arises. Therefore, cooling effect is produced by means of heat of water vaporization as shown in Figure 7(a).…”

In addition to humans' thermal comfort, air-conditioning (AC) could be required for various nonhuman applications, for example, animals' AC, greenhouse AC, food storage and transportation, industrial processes, and so on. In this regard, optimum conditions of air temperature and humidity are explored and compared on psychrometric charts. Thermodynamic limitations of existing AC systems are discussed from the subject point of view. Consequently, four kinds of low-cost energy-efficient AC systems, namely: (i) direct evaporative cooling (DEC), (ii) indirect evaporative cooling (IEC), (iii) Maisotsenko cycle (M-Cycle) evaporative cooling (MEC), and (iv) desiccant AC (DAC), are investigated for climatic conditions of two cities, that is, Multan (Pakistan) and Fukuoka (Japan). In addition, systems' fundamentals and principles are explained by means of schematic diagrams and basic heat/mass transfer relationships. According to the results, performance of all systems is influenced by ambient air conditions; therefore, a particular AC system cannot provide optimum AC for all nonhuman applications. However, one or other AC system can successfully provide desired conditions of temperature and relative humidity. It has been concluded that evaporative cooling systems provide low-cost AC for dry climates, whereas DAC system is found energy efficient and viable for humid climates.
