“…External environmental impacts such as solar gains on the transparent portion of the façade greatly influence the energy demand, particularly for cooling but also heating (Kharchi et al 2012). Undesirable indoor over-heating caused by solar heat gains may cause occupant's discomfort (Marino, Nucara, and Pietrafesa 2017).…”

The building skin has evolved enormously over the past decades. The energy performance and environmental quality of both the interior and exterior of buildings are primarily determined by the building envelope. The façade has experienced a change in its role as an adaptive climate control system that leverages the synergies between form, material, mechanical and energy systems towards an architectural integration of energy generation. The PowerSKIN Conference aims to address the role of building skins to accomplish a carbonneutral building stock. The focus of the PowerSKIN issue 2021 deals with the question of whether simplicity and robustness stay in contradiction to good performance of buildings skins or whether they even complement each other: simplicity vs performance? As an international scientific event - usually held at the BAU trade fair in Munich - the PowerSKIN Conference builds a bridge between science and practice, between research and construction, and between the latest developments and innovations for the façade of the future. Topics such as building operation, embodied energy, energy generation and storage in the context of the three conference sessions envelope, energy and environment are considered: – Envelope: The building envelope as an interface for the interaction between indoor and outdoor environment. This topic is focused on function, technical development and material properties. – Energy: New concepts, accomplished projects, and visions for the interaction between building structure, envelope and energy technologies. – Environment: Façades or elements of façades, which aim to provide highly comfortable surroundings where environmental control strategies as well as energy generation and/or storage are an integrated part of an active skin. The Technical University of Munich, TU Darmstadt, and TU Delft are signing responsible for the organisation of the conference. It is the third event of a biennial series: April 9th 2021, architects, engineers, and scientists present their latest developments and research projects for public discussion and reflection. For the first time, the conference will be a virtual event. On the one hand, this is a pity, as conferences are also about meeting people and social interaction; on the other hand, it offers the possibility that we can reach more people who connect from all over the world.

“…Individual shading practices are developed based on the outcome of the two. Dynamic modeling studies typically target the former stage and provide analysis balancing energy, daylighting and thermal comfort to inform windows and facade design that may involve passive or active protection from direct sunlight entering interior spaces [1,2,3,4,5]. Some modelling studies focus on the occupancy stage, with data derived from field studies, to help identify window treatments optimized to address contextualized challenges for a given architectural setting [6].…”

One of the important areas of occupant–building fabric interaction with IEQ consequences is windows’ shading. The relevance of shading has been explored through modeling studies in the context of energy, daylighting and thermal comfort, typically aiming to inform the design stage. In owner occupied housing the architectural design sets the scene for subsequent residents’ decisions concerning windows treatment. Here, based on varied treatments for 20m2living room window observed during an in-depth building performance evaluation in same homes, dynamic modeling in TRNSYS is used to establish the related heating loads and internal temperatures. The results allow to rank five shading usage scenarios for three physical settings, namely lack of shading, external blind and internal curtain on lower half of the window, in terms of their overheating mitigation potential, based on simplified assumptions for heating, ventilation and shading practices. The modelling points towards severe overheating issue and crucial impact of shading usage patterns on its mitigation. Yearly modelled share of overheating hours (>26 °C) are almost double for unshaded scenario compared to the most effective shading strategy (25% and 13%). The simulation contributes to understanding of the field monitoring results where the unshaded living rooms experience more severe overheating, and the two shading settings in place are associated with comparable internal thermal conditions, respectively 22% vs. 5% and 6% of yearly share of overheating hours. The simplification of human-HVAC-building interaction model likely obfuscates solar heat gain control contribution to heating load.

“…The use of solar energy in building is an important issue because of its contribution in the reduction of the fossil fuel consumption and the harmful emissions of the pollutants into the environment [3].In Iran, solar energy is mostly used for projects such as designing and building a solar shower, solar water heating installation and solar parks and no activities are done to construct solar chillers [2]. Using solar energy for heating and cooling of buildings is a new idea that was raised in 1930 and reached considerable progresses in less than a decade [4].…”

Rising energy costs and environmental problems, also the limited resources of fossil fuels, have forced humans to use renewable energy. One of the systems that are commonly used is the cooling system, by means of solar energy. Since these models have a wide variety of effective variables, such as the temperature, latitude, the length of the day, also due to the nonlinear relationship between the variables, conventional modeling methods are inefficient. Therefore regarding to the extensive capabilities of simulation models in modeling a wide range of variables with complex and nonlinear relationship, in this study with the approach of simulating solar systems, an effective survey in the field of economic and efficiency of such systems, is presented.
