Today's world places increasing emphasis on comfort within living spaces. The growth in awareness of energy conservation and environmental preservation has gradually contributed to the widespread use of smart home control systems. In this study, data related to human comfort conditions were compiled, and the control of smart devices in home environments was explored. Specifically, information communication technology and the Internet of Things (IoT) were combined to create a smart control system that creates a comfortable, energy-conserving home environment through the concurrent monitoring of both indoor and outdoor environmental data. If the outdoor indicators are ideal (denoting a comfortable environment) but the indoor indicators are not ideal (denoting an uncomfortable environment), the system opens a window to allow the incorporation of favorable outdoor environmental factors into the indoor environment. When the outdoor environment is uncomfortable, the window is closed to prevent the infiltration of unfavorable outdoor environmental factors. When the indoor indicators are nonideal, various types of equipment are activated according to the detection values. For example, when the humidity level is overly high, the dehumidifier is turned on. When the concentration of particulate matter with a diameter of < 2.5 µm is overly high, the air purifier is turned on. When the temperature is too high or low, the air conditioner is turned on, and when the CO 2 concentration is too high, the fan is turned on for ventilation. The values detected by each sensor and the operating conditions of each device are also displayed on the screen for the reference of the user, who can adjust the threshold values to their preferences.

In addition to the education of STEM (science, technology, engineering, and mathematics), this paper reviews the current relevant courses required in the field of construction projects from the practice point of view. The study summarizes the key courses in the education of construction engineers through document analysis, expert and scholar interviews, and subsequently establishes the key evaluation aspects and index reliability by Fuzzy Delphi Method. This study can provide the basis for the systematic curriculum design of construction engineering and management specialty in colleges and universities.

In recent years, with the rapid development of many cities in China and the massive increase of population, the problem of environmental pollution has brought great challenges to cities. The aim of the study is to establish an index system for eco-city in the developing process, taking qualitative and quantitative evaluation as the standard. The research result can reflect the development direction of eco-city construction and make city design meet the need of city sustainable development. Furthermore, it can be used as the basis for the development of eco-city system with Chinese characteristics.
