“…As a result of the analysis of the annual energy consumption according to the seven building shapes, it was determined that the H shape of the building in the Texas climate zone had the highest energy consumption among all the shapes studied [11,15]. (2) Natural lighting: Through an in-depth analysis of the sun's altitude, the amount of daylight, etc., many researchers have conducted various studies on how to determine the optimal orientation of a building and on designing the atrium from the perspective of introducing the natural light system for nZEB implementation (refer to Table 2) [16][17][18][19][20][21][22][23][24][25][26][27][28]. First, there are various studies related to determination of the optimal orientation of a building for reducing the building energy demand [16][17][18][19][20].…”

“…Compared to an individual house's optimal orientation, the mean of planning that considers the optimal building orientation at a community level was analyzed to more effectively reduce the annual energy cost [19]. Second, various studies have been carried out for efficient atrium design because the atrium shape is a very important factor in natural lighting [21][22][23][24][25][26][27][28]. Nasrollashi et al (2015) assessed the impact of the atrium-to-total building area ratio in terms of the energy efficiency and indoor environmental conditions, using the DesignBuilder software program.…”

“…As a result of this study, setting the atrium-to-total building area ratio as 1/4 was determined to be the most effective in terms of energy performance, daylighting, and thermal comfort (i.e., predicted mean vote) [25]. Mohsenin and Hu (2015) evaluated the daylight of an office building according to the atrium type (i.e., central, attached, and semi-enclosed), atrium proportions (i.e., Well Index), and roof aperture designs (i.e., monitor roof and horizontal skylight) through the DIVA software program as the climate-based daylighting modeling tool [26]. (3) Natural ventilation: To implement nZEB, an architectural design for inducing the reduction of the building energy demand through the effective influx of the outdoor air (i.e., natural ventilation) should be considered in the initial design stage.…”

Abstract:To cope with 'Post-2020', each country set its national greenhouse gas (GHG) emissions reduction target (e.g., South Korea: 37%) below its business-as-usual level by 2030. Toward this end, it is necessary to implement the net-zero energy building (nZEB) in the building sector, which accounts for more than 25% of the national GHG emissions and has a great potential to reduce GHG emissions. In this context, this study conducted a state-of-the-art review of nZEB implementation strategies in terms of passive strategies (i.e., passive sustainable design and energy-saving technique) and active strategies (i.e., renewable energy (RE) and back-up system for RE). Additionally, this study proposed the following advanced strategies for nZEB implementation according to a building's life cycle: (i) integration and optimization of the passive and active strategies in the early phase of a building's life cycle; (ii) real-time monitoring of the energy performance during the usage phase of a building's life cycle. It is expected that this study can help researchers, practitioners, and policymakers understand the overall implementation strategies for realizing nZEB.

“…Archsim and EnergyPlus were used to calculate energy consumption, which makes it easier to change the simulation inputs, such as the material and its thickness. DIVA was developed at Harvard University [26] and distributed by Solemma LLC [27], which has been used to carry out a series of daylighting analyses, including climate-based daylighting metrics, annual and individual time step glare analysis, etc. Eventually, Octopus, an evolutionary optimization tool, was used to perform the multiobjective optimization.…”

In the current context of increasing energy demand, timber-glass buildings will become a necessary trend in sustainable architecture in the future. Especially in severe cold zones of China, energy consumption and the visual comfort of residential buildings have attracted wide attention, and there are always trade-offs between multiple objectives. This paper aims to propose a simulation-based multiobjective optimization method to improve the daylighting, energy efficiency, and economic performance of timber-glass buildings in severe cold regions. Timber-glass building form variables have been selected as the decision variables, including building width, roof height, south and north window-to-wall ratio (WWR), window height, and orientation. A simulation-based multiobjective optimization model has been developed to optimize these performance objectives simultaneously. The results show that Daylighting Autonomy (DA) presents negative correlations with Energy Use Intensity (EUI) and total cost. Additionally, with an increase in DA, Useful Daylighting Illuminance (UDI) demonstrates a tendency of primary increase and then decrease. Using this optimization model, four building performances have been improved from the initial generation to the final generation, which proves that simulation-based multiobjective optimization is a promising approach to improve the daylighting, energy efficiency, and economic performances of timber-glass buildings in severe cold regions.

Economic growths lead to population increases in large cities. This has brought about the growing necessity for apartment housing which has resulted in higher density populations living in high-rise apartment complexes. Therefore, the urban microclimate is aggravated due to the increasing ratio of artificial coverage and substandard daylight availability. To achieve a comfortable living environment and improve urban microclimates, a process considering the daylight availability and the outdoor thermal environment is required when designing apartment housing complexes. This study selected a total of 27 valid cases using an orthogonal array, L27( 3 13 ) design of experiments (DOE). As a result of significance probability obtained in DOE analysis, the design factors that have an effect on the outdoor thermal environment and daylight availability were found to be building coverage ratio, distance between buildings, and azimuth. The rankings of the effect of design factors were shown to be in the order of azimuth > building coverage ratio > distance between buildings > floor area ratio > width/depth ratio. The surface temperature of the whole building decreased by 0.3 °C and Mean Radiant Temperature (MRT) decreased by 1.1 °C as a result of applying the greenery coverage ratio to apartment complexes. Heat Island Potential (HIP) also showed a decrease of 5.4 °C (at noon).
