“…On the other hand, internal ones only prevent excessive heat from entering the building after thermal heat gain (Pushkar and Yezioro, 2022). Up to 95% of the solar energy that hits the surface of the structure can be blocked by external shading (Aldabesh et al, 2021).…”

With the rising global temperatures, developing countries are one of the most adversely affected countries by climate change. Furthermore, changes in lifestyle and unsustainable ways of development have resulted in a shift away from passive strategies in the construction industry, which contribute to excessive energy consumption. This demands immediate action to use passive strategies and one of the most widely used passive strategies is shading devices, which can significantly lower the indoor temperature and give the structure the most efficient energy performance. Shading devices were a dominant identity of traditional architecture in Pakistan; however, it has been evident during the past decade the use of such devices has become obsolete due to modernized solutions. This study aims to examine the performance and effectiveness of shading devices in terms of heat gain and daylight levels in residential areas. A comparative case study methodology has been used. The fixed overhanging shading devices of six residential units in Mansehra City, Khyber Pakhtunkhwa province, Pakistan, have been used. Sun angles are calculated through the SketchUp tool Curic Sun to analyze and determine the performance of overhanging in both summers and winters. This article reveals south shading devices as an essential part of houses built before 2,000 in Mansehra City. Though, houses built after 2,000 do not consider using south shading devices to maximize energy use. This study emphasizes considering the type, design, and use of shading devices according to the building’s orientation to improve building performance and energy efficiency.

“…Spain is one of the countries in the European Union with the greatest potential for the use of renewable energy in buildings, particularly solar energy. This is due to the number of hours of sunshine (an average of approximately 2500 h of sunshine per year) it receives and the warm temperatures typical of a Mediterranean climate (temperatures remain on average every month above 20 • C but present seasonal variation) [4][5][6]. By incorporating bioclimatic design criteria, it is possible to generate buildings with almost zero consumption, moving us closer to what has been called sustainable architecture (i.e., the design of buildings that generate zero impact on the environment) [7].…”

Thermal Behavior in Glass Houses through the Analysis of Scale Models

Reducing energy expenditure in the construction sector requires the implementation of passive strategies in buildings. In Spain, consumption is centered on air conditioning systems associated with the demand for the building’s thermal envelope. A critical point of the enclosures is represented by glazed holes where much of the energy that is consumed is lost; however, homes increasingly tend to have large window openings due to the comfort and visual well-being they provide to users. In this study, we focus on an extreme case, analyzing a fully glazed house in its four orientations. It is necessary to evaluate the most energy efficient passive strategy for this type of construction. The results are based on the temperature analysis obtained during the monitoring of two scale models of a glass house. The results indicate that solar control foil glasses perform better in warmer weather stations. Regarding the cantilever installation, it influences the interior temperature and the central hours of the day, mitigating the increase in temperature as well as slowing the nighttime cooling.
