“…Because it is necessary to comply with the relevant regulations of China's highway transportation safety regulations, the 12meter-long IAA container consumes a lot of money and time in the transportation process. Furthermore, due to the temporarily dispatched for on-site construction, they are still not completed on time [9]. Not only that, but also based on the preconditions for ensuring the safe use of container houses, relevant regulations have made corresponding restrictions on the side window opening dimensions and building height of the container according to the structural characteristics of the container itself.…”

The concept of temporary buildings may have many forms or definitions in different countries and regions. In China, they are defined as buildings and structures that are simply constructed for temporary use of production and life and are required to be demolished within a specified period of time. Container houses are the most common type in China. They have been widely used in post-disaster recovery, temporary resettlement of industrial workers and low-income groups. It also plays an important role in different historical stages. It is undeniable that they have the advantages of simple construction technology, fast construction speed, integration and high degree of modularization in practical application. However, from the beginning of the Wenchuan earthquake in 2008, as well as the subsequent series of natural disasters, their design and functional defects were exposed. Through the spot investigation and questionnaire survey, this paper summarized these issues. For the reason that, this study attempts to fill this gap by introducing a new lightweight reconfigurable structure system (LRSS). First of all, in order to meet the needs of national conditions, the system is based on new modular design and manufacturing methods, quick to build and construction, but also easy to disassemble and transport. Moreover, the new design breaks through the traditional style of component form and size restrictions, with more human and sustainable features. Finally, through computer simulation and analysis, it is convinced that the new products have better comprehensive performance. Multiple comparison results are sufficient to illustrate the new structural system can meet the demand of people whom at different age even different social stratum, and ultimately achieve a win-win results from both social and environment system.

“…As prior studies related to NZEHs have shown, several simulations have been conducted to achieve net-zero energy through a combination of energy-efficient technology and renewable energy. Optimizing the design of building envelopes (insulation and windows, airtightness performance, and more) for the load reduction in residential buildings [4][5][6][7][8][9][10][11][12] is one way to achieve this. Baek et al analyzed energy usage for six houses of the same shape, size, and renewable energy system located in Daejeon, Korea, which were designed with the object of net-zero as empirical cases of NZEHs.…”

Over the past 20 years, net-zero energy house (NZEH) construction costs have steadily decreased because of many reasons, such as technical progress, energy-saving design obligations, and dramatic cost reductions in renewable energy systems, especially solar power systems. Currently, the costs of NZEH are estimated to be about 5% higher than similar-sized houses. These additional costs are mainly for installing PV systems, which can be offset by energy saving costs. This study assessed energy performance and load matching through remote monitoring systems, and energy costs were analyzed for two-family houses. The two houses were all-electric houses and different in both size and location. A 6 kWp grid-connected PV system and 16 kW air source heat pump for space heating and domestic hot water were equally implemented. After data analysis, 100% of the energies were supplied through the PV system for 3 years, thus achieving net-zero energy. According to the Korean residential electricity tariff system, the annual electricity charges were, on average, between USD 105.1 and USD 121.4 after adding demand charges and value-added tax for import electricity charges. The energy cost reduction rate, compared to the same house without a PV system, was about 95%, and the simple payback period of the 6 kW PV system in NZEH was about 6 years. In addition, the annual load cover factor and supply cover factor as load-match indices between electricity generation and the load were in a range of 0.39–0.49 and 0.37–0.42, respectively.

“…The version of the competition, Solar Decathlon Latin America and Caribbean 2015 (Cali, Colombia), to which the prototype presented in this article was submitted, unlike previous editions [8][9][10][11][12][13], was given a social approach, which allowed researching on other architectural typologies and sustainable-healthy construction solutions, where the transfer to society of the environmental strategies implemented in these prototypes gained special relevance. The objective was no longer to present a housing cell where excellent comfort conditions and minimum energy consumption were achieved on the basis of technology decontextualized socioeconomically from the society where the competition was held [14].…”

The AURA 1.0 prototype is a sustainable social housing proposal, designed by the University of Seville and built for the first Latin American edition of the prestigious Solar Decathlon competition. Different conditioning strategies were integrated into this prototype, optimized for a tropical climate, and focused on contributing positively to the health of the most humble people in society. In this moment, in which a large part of the world population is confined to their homes due to the Covid-19 pandemic, we have the opportunity (and the obligation) to reconsider the relationship between architecture and medicine or in other words, between the daily human habitat and health. For this reason, this analysis of aspects derived from the interior conditioning of the homes is carried out. The main objective of the Aura proposal is to be able to extract data through a housing monitoring system, which allows us to transfer some design strategies to the society to which is a case study, in order to promote environmental comfort and, therefore, people’s health. The AURA 1.0 prototype develops flexible and adaptable living spaces, with a high environmental quality, in order to maintain the variables of temperature, relative humidity and natural lighting within a range of comfort required by the rules of the event. To achieve this end, the prototype develops an architectural proposal that combines passive and active conditioning strategies, using construction qualities and typical costs of social housing. These strategies allowed the project to achieve the first prize in the Comfort Conditions test. So, this paper presents an appropriate and tested solution that can satisfy comfortability and health of residents who live in social housing while maintaining low energy consumption.
