“…The plant design proposed significantly and effectively improves indoor thermo-hygrometric conditions necessary for this kind of environment. Here, indoor air quality and ventilation requirements are crucial for thermal comfort, and, as some important research has demonstrated, for the health, well-being, and optimal work conditions of the occupants [24,28,32,36,37]. This aspect was proved by the specific value and distribution of the obtained indoor climatic parameters that allow the achievement of comfortable conditions.…”

The aim of our present research is to investigate possible solutions for the achievement of indoor comfort with the absence of any draft risks in the occupied zones of Cultural Heritage school building. A simple method for sustainable, reversible, and easily maintainable operations on the plant system, oriented to indoor comfort improvement and possible building-plant system refurbishment, is provided. It is based on thermal comfort assessment at an early design stage, carried out by dynamic simulation and CFD techniques. It helps to identify major ineffective equipment in historical school buildings, and potential sustainable, noninvasive, reversible, and conservative measures. Results obtained by a simulation exercise of a historical school building, a check case study, showed that the evaluation of thermal comfort conditions can be a strong guideline for reversible plant design. This guarantees building protection and preventive conservation. Refurbishment and retrofitting solutions, with a lower impact can be identified. Thus in depth assessment of the building physics and plant performance aiming at energy efficacy and sustainability, can contribute to finding out the balance between energy saving, sustainability, and quality of life. Our method can be a useful tool for effectiveness analysis on retrofit and refurbishment measures for similar case studies.

“…This software remains under development; two blocks on Parametric Analysis and Optimization have been used for real design. A. Zhang et al [45] organized an integrated method for school and schoolyard design in northern China through the hybrid use of DesignBuilder and a three-dimension microclimate tool, ENVI-met. In their suggested process, the tool ENVI-met completed the outdoor climate calculations, which were imported to DesignBuilder as boundary conditions.…”

Early simulation work in the decision-making stage faces several challenges, including, for example, rapid changes of design, input variable uncertainties, and the lack of design information, although early design work represents a large percentage of energy saving potential. The availability of simulation tools for early design stages can help the architect analyze more alternatives. In this study, the existing simulation tools were explored and classified into three categories: simulation plugins based on the design software, geometry user interfaces for a simulation engine, and self-governing simulation tools. Each category’s typical tools were illustrated with their use, and a uniform standard comparison was conducted to screen tools that are available in the early design stages. The future trends of simulation tools are discussed in the second part: building databases based on existing knowledge, uncertainty and sensitivity analyses, and optimization. Time-consuming simulation is a problem in the use of simulation tools in early design stages. Advanced techniques were developed in this part for fast computing, i.e., cloud computing, parallel computing, meta-models, and more statistical methods. This paper illustrates the practical application of particular simulation tools in the early design stage, presents their limitations, and discusses decision-support tools for specific building design activities.

“…), and subjective questionnaire surveys are conducted near the monitoring sites [15][16][17][18]. The field monitoring outdoor thermal comfort evaluation method is to find out the comfortable or acceptable thermal conditions for local residents, to understand human body perception of the thermal environment [19][20][21], and to provide valuable reference for urban planners and park designers [9,[22][23][24][25], so as to formulate strategies for optimizing the outdoor thermal environment.…”

Urban parks are an important component of urban public green space and a public place where a large number of urban residents choose to conduct outdoor activities. An important factor attracting people to visit and stay in urban parks is its outdoor thermal comfort, which is also an important criterion for evaluating the liability of the urban environment. In this study, through field meteorological monitoring and a questionnaire survey, outdoor thermal comfort of different types of landscape space in urban parks in Chengdu, China was studied in winter and summer. Result indicated that (1) different types of landscape spaces have different thermal comforts, (2) air temperature is the most important factor affecting outdoor thermal comfort; (3) because the thermal sensation judgment of outdoor thermal comfort research in Chengdu area, an ASHRAE seven-sites scale can be used; (4) the neutral temperature ranges of Physiological Equivalent Temperature (PET) and Universal Thermal Climate Index (UTCI) in Chengdu in winter and summer were obtained through research; (5) and UTCI is the best index for evaluating outdoor thermal comfort in Chengdu. These findings provide theoretical benchmarks and technical references for urban planners and landscape designers to optimize outdoor thermal comfort in urban areas to establish a more comfortable and healthy living environment for urban residents.
