“…It was also noted that building orientation and shape should first be considered in optimal designs for improving thermal insulation performances of building envelopes in cold regions [24][25][26]. Outdoor shading devices, such as overhangs and louvers, have also attracted great attention in recent days in terms of promoting energy efficiency of passive buildings in cold regions [27,28]. Overall, recent reports highly suggest that analyzing and optimizing envelope structures for passive buildings is the necessary and promising approach to achieving energy efficiency, a sustainable environment, and indoor thermal comfort in severe cold regions.…”

The present study provides comprehensive analyses of a newly constructed passive energy-efficient building located in Harbin, China, which is a prime example of how to design a passive building that withstands the severe cold climate in northeast Asia. Conduction transfer functions of heat flux equilibrium are employed to simulate energy consumption characteristics of the paradigm passive building. The climatic conditions in severe cold region are analyzed, and the energy-saving designs in the studied engineering cases are summarized for their practical applications. Building physical models are established to perform numerical simulation analyses on the passive building paradigm in northeast Asian frigid zone. The dominant technical parameters of envelope structure affecting energy consumption in severe cold region, including thermal insulation thickness and heat transfer coefficient of building envelope, as well as window-to-wall ratio for each building facade, are taken into consideration as simulation variables to calculate cooling load, heating load, electricity consumption, and CO2 emission, which account for energy efficiency of passive buildings. The simulation results demonstrate the high energy-saving potential of the proposed passive building design and render the optimal energy-efficient parameters suitable for severe cold regions, which can reduce energy consumption and CO2 emission while ensuring comfort for occupants. The present study provides a theoretical reference for envelope structures of passive buildings in severe cold regions, which is of great significance to the development of green buildings and relevant policies.

“…The shading of buildings has become a more significant consideration in China's hot summer and cold winter areas, together with occupants' increasing awareness of energy saving. The practice of building shading can effectively reduce direct sunlight in the summer and, therefore, the air conditioning cooling load [2][3][4], which plays a crucial role with respect to energy saving in buildings. The application of building shading is relatively common in new buildings.…”

Through objective measurement, subjective measurement, and prioritization methods, this study evaluates the impacts of different shading facilities on the indoor environment of multi-story residential buildings, such as dormitories. The objective measurements mainly include the operative temperature, daylight factor, and sound pressure level. The subjective measurement is obtained from occupant votes regarding their satisfaction with the thermal uniformity, natural lighting, external noise, and the overall indoor environment. The results show that the subjective evaluations were significantly more reliable than the objective measurements for predicting indoor environmental satisfaction. The prioritization method of the ordered logistic regression was then used to evaluate the impact of perceived indoor environmental quality on overall satisfaction. The results show that the impact of the perceived indoor environmental quality on overall satisfaction varied with the shading facilities. In addition, the occupants commented on the function of items affecting their application preferences and provided recommendations for improving balconies and sunshades to provide occupants with better indoor environments.
