  abstract     = {{The popularity of fully glazed facades in office building design has been well-established over the years. One of the techniques used to achieve a seamless outer appearance is the shadow box system, which is composed of two layers of glazing with an air cavity in between. It has gained widespread popularity in markets worldwide due to its potential for creative design and flexibility. However, it is prone to issues such as condensation, contamination, and overheating. This research utilized a mockup test approach to study the issue of overheating in shadow box systems and analyze the main causes of this problem. The findings have significant implications for the design of shadow box systems. The results of the mockup test indicate sun altitude in relation to the geolocation and facade orientation plays a major role in overheating the shadow box. Additionally, careful consideration should be given to the design of ventilation openings to mitigate the overheating issue. This ongoing analysis aims to develop strategies to mitigate the issues found in shadow box systems and future research will involve a comprehensive analysis of various types of shadow box systems.}},

  abstract     = {{People in cities are often exposed to complex mixtures of sounds, some originating from nature along with some created by human activities like traffic noise, sounds of industrial machinery, or music. This research aimed to study how the acoustic environment of a university campus is perceived by people. The procedures for soundscape data collection and analysis were based on the ISO 12913 series. 30 volunteers divided into four groups participated in a “soundwalk” at the campus of the architecture school in Detmold, Germany, filling out questionnaires while sound
measurements and recordings were being taken. After the soundwalk, the data from the questionnaires, sound measurements, recordings, pictures and videos were analyzed. The findings suggest that people’s perception of sound is susceptible to the context, as participants seemed to shift their preference according to the ongoing
activities that drew attention, such as a construction site, sounds from children playing, music and groups of people. The results provide new evidence and insights about the acoustic environment and the soundscape of the university campus and can inform stakeholders to improve environmental quality.}},

  abstract     = {{Façades cover a significant amount of surfaces in cities and are in constant interaction with the acoustic environment. Noise pollution is one of the most concerning burdens for public health and wellbeing; however, façade acoustic performance is generally not considered in outdoor spaces, in contrast to indoor spaces. This study presents a systematic literature review examining 40 peer-reviewed papers regarding the effects of façades on the urban acoustic environment and the soundscape. Façades affect sound pressure levels and reverberation time in urban spaces and can affect people’s perception of the acoustic environment. The effects are classified into three groups: Effects of façades on the urban acoustic environment, including sound-reflecting, sound-absorbing and sound-producing effects; Effects of façades on the urban soundscape, including auditory and non-auditory effects; Effects of the context on the acoustic environment around façades, including boundary effects and atmospheric effects.

  abstract     = {{Urban noise pollution is a major environmental health problem. International organizations are making efforts to prevent health damage due to high levels of noise in cities, but the design of the built environment typically neglects the acoustic impact of architectural projects. Building facades, covering a substantial part of the vertical surfaces of the urban fabric, have a significant effect on the wellbeing of the population and on the environmental impact of buildings. Facade geometries and materials interact with the diversity of sounds in the city composing soundscapes that influence the health, comfort, and productivity of people inside and outside of buildings. This study gives an overview of the elements involved in the composition of the urban soundscape and revises the potential effects of sound-reflective and sound-absorptive facades. With the purpose of exemplifying the integration of acoustic data into facade design processes, a parametric design workflow is developed to experiment with acoustic simulations of a street environment, alternating between sound-reflective and sound-absorptive facades.}},
