This paper examines the influence of weather conditions on the electricity production of photovoltaics panels in region distinguished by its subtropical mountainous climate with the help of energy plus simulation tool. A back propagation neural network BPNN model is used to explore the relationship between weather categories and pv generation. Find...
The influence of recycled concrete powder (RCP) on the thermal insulation of alkali-activated materials remains unclear. Hence, this study develops an innovative alkali-activated insulation mortar, serving RCP and blast furnace slag as the precursor and expanded polystyrene (EPS) beads as fine aggregate, together with air entrainer. Experimental re...
Reducing the operational energy demand while maintaining a comfortable thermal environment is an essential approach to achieving energy-efficient buildings. The premise lies in accurately assessing and predicting the occupant's thermal sensation. However, most thermal comfort models are not entirely suitable for dwellings, since the effects of time...
This study investigates the optimization of urban ventilation in Zhao’an Old Town, Fujian, through the integration of Computational Fluid Dynamics (CFD) simulations and field measurements. The findings underscore the critical roles of spatial layout indicators, such as the Frontal Area Index (FAI), Opening-to-Facade Ratio (OFR), and Building Volume...
In the context of the escalating challenge of climate change, optimizing buildings’ energy performance has become a critical research area, yet studies specifically targeting library buildings are scarce. This study addresses this gap by investigating the impact of multi-objective optimization on energy efficiency and occupant comfort in educationa...
Respiratory infectious diseases have affected the health of the elderly. This study investigated the optimization of physical barriers as a low-cost design strategy to reduce the risk of infection in nursing homes for the elderly in Hong Kong, which were significantly affected by the outbreak of COVID-19. First, data on two types of rooms, single a...
As global demographics shift towards an aging population, the need for sustainable healthcare environments becomes increasingly critical. This study addresses this imperative by examining the application of Green Building Rating Systems (GBRSs) in healthcare facilities, such as hospitals and nursing homes. It emphasizes the urgency of developing en...
The interaction between high-rise and low-rise buildings in high-density cities can have an impact on the wind environment of surrounding streets and areas. In Hong Kong, a city with a large number of high-rise buildings, there are public open areas between these buildings that are potential sites for public facilities. However, there is a lack of...
To achieve the goals of carbon peaking, a national policy instrument for carbon peaking in the building and construction sector has been launched by the Chinese MOHURD (30 June 2022). We have developed an actionable framework for implementing these policy objectives. The framework was designed by classifying and prioritizing selected strategic gove...
By 2021, the urbanization rate of China had reached as high as 64.72%. At the same time, the efficiency-driven urban planning paradigm had shifted to that of an efficiency-and-fairness intent. Fairness refers to the publicness of public open spaces (POS) as an indicator of an inclusive and fair city. The authors are interested in the measure of POS...
Triggered by the global call for low-carbon design, the idea of “productivity for a building envelope” has permeated the role of building to produce alternative (renewable) energy alongside weather and solar protection, and the authors hypothesized that the geometrical shape and configuration of a roof is a significant contributor to low-carbon des...
This study investigates the differences in outdoor thermal comfort in different spatial types over long-term observations during the transition season in a cold region. Using the Universal Thermal Climate Index (UTCI) as an evaluation index, subjective questionnaires and field surveys were conducted on thermal comfort in three different typical out...
The urban environment faces tremendous pressure from the intensification of urbanization. The pursuit of a comfortable built environment aims at higher and tougher grounds, leading to increasing energy consumption of heating, air conditioning, lighting, etc. In the residential sector, thermal insulation is a practical, efficient approach to moderat...
