“…In building facade design, fenestration design usually represents a key point in energy consumption. W. Bustamante et al [54] introduced a simulation tool integrating thermal and lighting to support the fenestration of system design. This integrated tool, named mkSchedule, focuses on complex fenestration systems in office buildings.…”

Early simulation work in the decision-making stage faces several challenges, including, for example, rapid changes of design, input variable uncertainties, and the lack of design information, although early design work represents a large percentage of energy saving potential. The availability of simulation tools for early design stages can help the architect analyze more alternatives. In this study, the existing simulation tools were explored and classified into three categories: simulation plugins based on the design software, geometry user interfaces for a simulation engine, and self-governing simulation tools. Each category’s typical tools were illustrated with their use, and a uniform standard comparison was conducted to screen tools that are available in the early design stages. The future trends of simulation tools are discussed in the second part: building databases based on existing knowledge, uncertainty and sensitivity analyses, and optimization. Time-consuming simulation is a problem in the use of simulation tools in early design stages. Advanced techniques were developed in this part for fast computing, i.e., cloud computing, parallel computing, meta-models, and more statistical methods. This paper illustrates the practical application of particular simulation tools in the early design stage, presents their limitations, and discusses decision-support tools for specific building design activities.

“…39,40 The areas with high irradiance require a shading surface to protect the walls and roof from the heat of solar energy. 41,42 PV can be used to provide this shading for the buildings. The energy produced by PV array will reduce the power consumption of the building from the main grid.…”

This research work presents shading of building in hot and dry climate areas using rooftop photovoltaic arrays. Electrical power generation using photovoltaic arrays helps in reducing dependency on the utility grid. Areas with high intensities of solar radiation for a longer duration of time create high daily temperature. The Kingdom of Saudi Arabia (KSA) falls in high temperature and very low humidity climate zone. KSA has increased electricity tariff rates by 260% since 1 January 2018, has planned goals of generation of 9.5 gigawatts of renewable energy by 2030, and has ideas of constructing a self-sustainable city by the Red Sea. Energy analysis performed in this research is to calculate benefits of placing photovoltaic arrays on a rooftop of Buildings. These benefits include the electrical energy production and reduction of building cooling load by shading effect on a rooftop. By placing photovoltaic arrays on rooftop, up to 23% energy saving of cooling load can be achieved. The net annual output of photovoltaic generation per panel is discussed by adding energy generation and saving in cooling load of the building. The distance between the photovoltaic arrays is optimized for maximum benefits of electrical energy and saving in cooling loads. Practical application: Photovoltaic arrays on rooftops for shading effect have practical benefits of energy savings in hot environment areas where high solar irradiance heat up the buildings. Photovoltaic arrays provide shading and energy generations which is a step towards zero energy buildings.

“…Stazi et al 2014studied the impact of perforated aluminum panels as solar protection system (SPS), on energy consumption and thermal comfort in a Mediterranean climate in Italy. Vera et al (2016) and Bustamante et al (2017) developed a tool for integrating the energy and light analysis of different solar protection systems with highly complex geometries. In particular, solar protection systems with curved and perforated aluminium horizontal slats are studied to implement the analysis during the early design stages of office buildings.…”

Santiago de Chile is a city with a semi-arid climate, with prolonged periods of high temperature and solar radiation. In recent years, in this city, office buildings have been built with high window to wall ratio (WWR) facades. 65% of the office buildings built in the period 2005-2014 have a WWR higher than 60%. Only 5% of these buildings showed an efficient glazed façade solar protection device. One of these systems corresponds to an exterior textile solar protection. This type of systems, together with the perforated screens, could be effective solutions for the solar protection of glazed facades, reducing the cooling energy consumption of buildings, without risking the visual comfort of the occupants. The objective of this research is to evaluate the solar transmission and lighting of seven perforated solar protection systems. Three of these systems correspond to external textile solar protections, and the remaining four are perforated metallic screens. The evaluation was carried out by applying an experimental protocol in two different calorimeters that simulate an office space. In one of the calorimeters, the solar protection systems are installed while the other is used as a reference without any solar protection system. Measurements were made with illuminance sensors and pyranometers. The horizontal illuminance sensors from Konica Minolta (T10) were installed outdoor and at different points inside the calorimeters. Near the facade, vertical indoor and outdoor pyrometers were installed (Kipp Zonnen, CMP11 and Sp Lite 2). The measurements on the north facade are made in summer on clear days. The measurements showed a reduction in solar transmission of 82.1% (metallic screen, 40% drilling) to 94.7% (cloth, 3% drilling) and from 70.8% to 95.4% in the transmission of lighting respectively.
