“…Passive buildings are characterized by a lower heating energy consumption than typical buildings (reduction in heating energy consumption by 80-90%) with a higher initial cost of building development compared to typical buildings [6,7]. Furthermore, comparing a passive house to a low-energy building, it brings many more benefits as a well-designed and constructed passive building provides a higher comfort level for its occupants [17]. In [18], the authors analyzed the energy, environmental, and ecology effects of integrating passive strategies into buildings.…”

“…It was found that depending on the combination of passive techniques applied, it can provide energy savings ranging from 6.7 to 66.2%, a reduction in the life cycle cost ranging from 12 to 52%, and payback periods of 0.5 to 84 years. In [17], the results of the comparison of five houses with passive and net-zero technologies with a traditional house were presented. The study revealed that the basic model containing renewable energy sources had a more significant impact on the cumulative cost benefit in not only economic but also social and environmental terms.…”

The building sector contributes significantly to global final energy consumption and energy-related CO2 emissions. The demand for sustainable and energy-efficient passive buildings with a minimal ecological footprint has increased due to the global energy crisis, climate change, and environmental concerns. This need can be met by constructing passive buildings. However, to develop a building that is truly passive, it is required to meet many passive house conditions, negligible for typical buildings, which increase the project complexity and pose challenges and risks threatening its successful completion. The aim of this work is to present the findings from a quantitative risk analysis in passive construction based on the results of expert surveys that were carried out using a Computer-Assisted Web Interview. Feedback from expert surveys covering the experience of 748 passive buildings projects from seven countries (Poland, Germany, Great Britain, the United States, Australia, Spain, and Austria) allowed us to access the frequency of occurrence, severity, detectability, and Risk Priority Numbers of the 32 risk factors identified in passive buildings projects. Those risk factors were identified based on literature research, risk interviews, scenario analysis, brainstorm sessions with passive buildings specialists, and our own observations of passive buildings projects. This study revealed that incorrect costing was the most frequent issue; complicated, non-compact building shapes with an unfavorable area-to-volume ratio had the highest severity of effects; the wrong interpretation of correctly prepared drawings and details obtained from the designer had the lowest detectability; and incorrect costing had the highest Risk Priority Number. In addition, this study allowed us to identify a narrow group of critical risk factors that are the most significant (have the highest RPN) and to which special attention should be paid in the risk-management process.

“…In European social housing, funds are set aside for special ecological construction at the time of planning, and it is also mandatory to include a certain size of passive housing in social housing in proportion to the area [ 8]. For example, the Vauban eco-community in Freiburg, Germany, which focuses on solar power generation, has set standards for wall insulation, recycling of building renovation materials, public participation, and terra-energy use, and has become a model community for energy conservation and sustainability.…”

Social security-oriented rental housing is not only an important way to solve the housing problem for urban residents, but also an effective means to improve the quality of urban life and promote sustainable development of urban environment. Past public rental housing emphasized efficiency in construction, allocation, and use, but lacked public functionality, resulting in many projects becoming identical "miniature commercial housing". Therefore, this article focuses on the "two-type" security-oriented rental housing and lists new design cases of Modern rental housing. It proposes that social security-oriented rental housing should enjoy multiple rights and have the aesthetic function of open shared space and personalized innovation, low-carbon emission reduction intelligent function, fair transfer and participation function. Measures such as providing preferential housing, rental or new housing subsidies, and land price subsidies are provided for specific populations in need. By realizing the design concept of multiple values, social security-oriented rental housing can not only maintain basic rights, but also enhance the quality of residents' lives, further improving their quality of life and environmental friendliness.
