The façade is an important, complex, and costly part of a building, performing multiple objectives of value to the occupants, like protecting from wind, rain, sunlight, heat, cold, and sound. But the frequency of façade fires in large buildings is alarming, and has multiplied by seven times worldwide over the last three decades, to a current rate of 4.8 fires per year. High-performing polymer based materials allow for a significant improvement across several objectives of a facade (e.g., thermal insulation, weight, and construction time) thereby increasing the quality of a building. However, all polymers are flammable to some degree. If this safety problem is to be tackled effectively, then it is essential to understand how different materials, and the façade as a whole, perform in the event of a fire. This paper discusses the drivers for flammability in facades, the interaction of facade materials, and current gaps in knowledge. In doing so, it aims to provide an introduction to the field of façade fires, and to show that because of the drive for thermal efficiency and sustainability, façade systems have become more complex over time, and they have also become more flammable. We discuss the importance of quantifying the flammability of different façade systems, but highlight that it is currently impossible to do so, which hinders research progress. We finish by putting forward an integral framework of design that uses multi-objective optimization to ensure that flammability is minimized while considering other objectives, such as maximizing thermal performance or minimizing weight.

With the intensification of urban development in Chinese cities, mixed land use in urban centers extends vertically into 3-D and expands its scale from a single building to commercial clusters. The multi-level pedestrian system in city centers also changed its role from one of traffic isolation to spatial integration, where transit nodes, street sidewalks, squares, building entrances, atriums, and corridors are interconnected, both horizontally and vertically, into a whole spatial system, within which pedestrian flows are guided and shopping facilities are arranged. This paper uses spatial configuration analysis of space syntax to examine the impacts of spatial patterns on movement distribution and the business performance of tenant mix in the multi-level commercial system of the Nanshan Commercial Cultural District in Shenzhen, China. The key objective is to better understand the interactions between the socio-economic variables and spatial design parameters of a shopping complex. The research findings point to the importance of multiplicity between syntactic variables and other spatial variables in influencing the pedestrian flows, business performance and tenant mix in highly complex commercial systems. Particularly noteworthy is the relationship between spatial accessibility measures and the location of escalators, and the ways in which individual commercial buildings are embedded into the overall spatial system. The study suggests that this may lead to the preliminary identification of the spatial qualities of effective vertical extensions of mixed land use in a high-density urban settings.

The number of public libraries is not good enough in Korea. The main reasons why there are not many libraries are: the lack of people's recognition of necessity and importance of public libraries, stingy investment by the central and local governments for building public libraries, and no policy on effective building of public libraries. Now, there should be a policy on building and operating small-size public libraries that the developed country adopts. Redevelopment of local areas and reconstruction of old apartment complex are the best chance of building small-size libraries in those areas. The apartment complex in which this study took place is going to be reconstructed in the near future. A small-size library can be built with a district office and a post-office as a multi-complex building. Building a small-size library with public institutions or business buildings in the place of redevelopment of local areas and reconstruction of old apartment complex is one of the best solution of solving the lack of public libraries in Korea.

Vertical greenery has become an important technological means to improve the ecological environment condition in urban high-density areas, especially in central areas of Chinese cities. The cost of vertical greenery has significantly increased both in the decision-making process of architectural design and in the assessment of the sustainability potential of urban complexes. The estimation and evaluation of the cost of vertical greenery have become important obstacles to multi-party investment in the construction of vertical greenery. Considering the factors of the building typology and full life-cycle cost, this paper constructs an assessment model of vertical greenery in seven types in urban complex, and suggests an optimized approach to vertical greenery in an urban complex.

A controller who is responsible for visiter's safety makes a decision about measures for visiter safety in human-based decision making process. Many potential accidents that are caused by human error lurk in results of the process. The accidents can be decreased by changing the decision making process from human-based into technology-based. Technology-based decision making process can catch a controller's attention through data filtering, alarm filtering, and so on. So, the controller can get information on occurrence of an unforeseen accident pro-actively. The objective of this study is to suggest a concept of 3D spatial information control system for visitor flow control in multi complex building using technology-based decision making process. This study shows utilization of the system and contribution.

This study considers that the establishment of a public library within multi-use complex is one of the most effective ways to expand infrastructure of public libraries in Korea. A survey on the complexation rates of public libraries in Seoul was made through on-the-spot visits and telephone interviews. It turned out that out of all 112 public libraries in Seoul, 55 of them are in multi complex buildings. In order to efficiently establish public libraries to multi-use complex, absolute consideration on the size, location, and space should be made. Moreover, if necessary, additional complexation with commercial facilities, schools, and local government buildings should be made.

A Special Building Zone, which could relieve or ignore part of the Building Act and the regulations in relevant laws, was practically established for the creation of new urban landscape, the improvement of construction technology, and the improvement of construction-related policy. However, due to the lack of understanding the Special Building Zone as well as the insufficiency of detailed standards in policies, the system currently cannot be operated in universal matters. In such circumstance, this study, which is based on the current data on the Special Building Zone defined in exiting law, attempts to analyze the multi-unit housing that has been planned by the system of Special Building Zone. Also, this study aims to derive the Special Building Zone's possibilities and implications that contribute to the improvement of landscape, so as to suggest solutions for effective improvement of the system. With the results above, solutions for the improvement of the system can be derived and summarized as the following. On the one hand, from 'planning perspective', it is necessary to improve the system in a comprehensive way with consideration of urban and local contexts. On the other hand, from 'procedure perspective', some foundation shall be prepared for a system that can allows comprehensive tasks, including the settlement of the zone, the alleviation/elimination of regulations, the approval of building's construction, the process of construction, and the monitoring.
