Both Holl and Nordenson pushed for the concrete scheme, while the clients would have preferred steel as they wanted the building finished as quickly as possible.33 Steel buildings are generally quicker to build and are often cheaper. But there were a number of advantages to a concrete building, particularly one with a load-carrying façade: the large thermal mass, which is inherently insulating, helps to keep the building cool in summer and warm in winter. In fact, while the building has limited supplemental air conditioning, it is largely cooled through passive means. Concrete as a structural material is also highly sound insulating and fire resistant, which makes it a great choice for a dorm building. Each single dorm room has nine operable windows that measure over 2ft × 2ft. The size and layout of the windows were designed to allow views for both standing and sitting occupants.34 The window jams are 18 inches deep, so they provide shade from the high summer sun while allowing the lower winter sun to penetrate the rooms.35
Change rates and weight values of energy consumption parameters for light steel buildings in severe cold region

Light steel buildings are widely used due to the advantages of light weight, assembly in the factory prefabrication site, convenient construction and short construction cycle. Especially in the cases of sudden fires, earthquakes, epidemics and so on, the advantages of light steel buildings are more obvious. With the outbreak of COVID-19 in 2020, all hospitals in Wuhan, China had a shortage of wards. In order to allow patients to get treatment quickly, Wuhan built the Huoshenshan hospital with a total construction area of 33,900 square meters in 10 days, and the Leishenshan hospital with a total construction area of 60,000 square meters in 18 days. The world had seen the speed of Chinese construction, and it had also made people more deeply realize the advantages and importance of light steel buildings. COVID-19 had continued to this day, and light steel building hospitals and nucleic acid testing stations are used in large quantities. However, the building envelope structure has the problems of high thermal conductivity and poor thermal inertia, more energy is needed to improve the indoor thermal environment and meet the thermal comfort needs of people in the buildings in severe cold regions.

Climate change may have multifaceted impacts on the safety and performance of infrastructure. Accounting for the different ways in which potential climate change scenarios can affect infrastructure is of paramount importance in determining appropriate adaptation and risk management strategies. Since bridges operate for long periods it is vital to identify the long-term effects of climate change on bridges and their possible adaptations. The contribution by Nasr, Kjellström, Björnsson, Honfi, Ivanov and Johansson deals with climate change impact on safety and performance of existing and future bridges. Typically, the building stock is not designed for deconstruction, and material recovery for reuse at the end-of-life of buildings is complex and challenging. Vares, Hradil, Sansom and Ungureanu presented the economical potential and environmental effects of reused steel structures. This is achieved via a case study, which highlights the environmental and life-cycle cost impact of reused steel structures. The study examines four scenarios of industrial steel buildings constructed with new and reused steel structures, and relevant comparisons are presented in terms of life-cycle costs and greenhouse gas emissions.
Cyclic Deformation Capacity of Structural Steels for Earthquake-Resistant Steel Buildings

The ability of steel building structures to resist earthquakes depends on the energy-dissipation capacity of the structural members. The energy dissipation capacity of steel members subjected to cyclic loading depends on the deformation capacity of the steel materials. Owing to the need for qualities such as weldability, strength, and deformation capacity, the structural members of steel buildings are generally made of low-alloy steel. Some carbon steels, whose chemical compositions are not significantly different from those of low-alloy steel, are also used as structural members of steel buildings. Therefore, to design earthquake-resistant steel buildings, it is necessary to elucidate the deformation capacity of these structural steels.
