“…The results indicated that design variations with certain block forms, azimuth angles and latitudes can generate a significantly enhanced sunlight reception and thermal performance. Seong et al (2011) investigated the geometrical elements of apartments and the design factors and regulations related to the solar right in South Korea. To satisfy the solar right regulations, a mathematical computational model and subsequent algorithm were developed to automatically adjust the height of apartments.…”

An algorithm-based parametric design method was developed to generate the layout of a high-rise housing complex with improved sunlight access and compliance with the relevant building code restrictions in South Korea. Integrated with computer-aided modelling and simulation, the algorithm automatically arranges multiple apartments according to their height, separation, the shaded area between adjacent buildings and setbacks from site boundaries. The algorithm was then implemented in three high-rise housing complexes across South Korea to validate its feasibility. In all three cases, the algorithm generated housing layouts that satisfied the considered building regulations and improved overall sunlight exposure conditions. Particularly, lower-density housing with fewer buildings or floors were found to be more effective in allowing sunlight access: more housing units were included in the longest sunlight exposure duration whereas fewer units were included in the shortest sunlight duration. The proposed parametric approach allows the effective execution of both diverse experiments in housing design layouts and assessments of layouts' sunlight access conditions, enhancing sustainable decision-making in the design process.

Sunlight has always played an important role in the design of human settlements. Well-designed urban structures, especially in moderate or cold climates, should be assured of direct sunlight in indoor living spaces and also in public spaces. Direct sunlight in a built environment is an important factor for health and well-being, the effective functioning of solar systems, and sustainable construction. However, many problems involved in the exercise of rights of access to sunlight can arise when sunlight is obscured by a tall cityscape. Many states, regions, and cities regulate solar access, but solar rights and landowner rights are in a permanent conflict. The high urban density of many cities with tall skyscrapers accentuates the problem of the availability of sunlight. This paper presents a review of existing regulations and metrics for ensuring the availability of direct sunlight in buildings and of assessment methods that have been adopted in multiple countries and cities. Approaches, methods, and tools of rights of access to sunlight are critically analyzed. The paper also details experiences from former socialist countries where strict long-term strict on direct access to sunlight in flats were applied.

“…The ever increasing number of high-rises and densification are likely to lead to an ignorance of the elements that must be considered in solar access design. Such issues result in further problems such as a violation of the right to sunlight or privacy invasion, which may decrease the quality of the dwelling environment [2]. Apartment housing, in particular, is frequently exposed to designs insensitive to the problematic aspects mentioned above, resulting in many negative effects caused by the high population density and floor area ratio [3].…”

Economic growths lead to population increases in large cities. This has brought about the growing necessity for apartment housing which has resulted in higher density populations living in high-rise apartment complexes. Therefore, the urban microclimate is aggravated due to the increasing ratio of artificial coverage and substandard daylight availability. To achieve a comfortable living environment and improve urban microclimates, a process considering the daylight availability and the outdoor thermal environment is required when designing apartment housing complexes. This study selected a total of 27 valid cases using an orthogonal array, L27( 3 13 ) design of experiments (DOE). As a result of significance probability obtained in DOE analysis, the design factors that have an effect on the outdoor thermal environment and daylight availability were found to be building coverage ratio, distance between buildings, and azimuth. The rankings of the effect of design factors were shown to be in the order of azimuth > building coverage ratio > distance between buildings > floor area ratio > width/depth ratio. The surface temperature of the whole building decreased by 0.3 °C and Mean Radiant Temperature (MRT) decreased by 1.1 °C as a result of applying the greenery coverage ratio to apartment complexes. Heat Island Potential (HIP) also showed a decrease of 5.4 °C (at noon).
