In order to solve the problem that building engineering construction needs to consume a lot of energy and cause environmental pollution, which will pose a great pressure on urban resources and environment, this paper proposes that, in building engineering construction, appropriate green construction technology must be selected in combination with the actual situation, so as to effectively reduce the energy consumption of building engineering and improve the use efficiency of building engineering. Firstly, good thermal insulation nanomaterials are selected, which are cost-effective, safe, and nontoxic and has small thermal conductivity, large heat storage coefficient, stable chemical performance, and good construction performance. Secondly, it also needs to be selected according to the actual service life of the building. Because the current evaluation system is mostly aimed at the planning and design stage, and the structure occupies a large part in the building, for example, the impact on the construction period accounts for more than 50% and the impact on the cost accounts for 35%. Therefore, Duan Xiaorong and others established the grey cluster evaluation model of green building structure design based on the triangular whitening weight function. Finally, according to the relevant national regulations, this paper optimizes the design of green buildings based on the basic principles of energy conservation and emission reduction, high quality, and high efficiency.

“…Greater impact in heating-dominated climates is perhaps counterintuitive since dynamic windows are often discussed as an effective technology to reduce solar heat gain. [5,9,10] However, most studies compare thermochromic window performance to single-pane glazing with no IR light mitigation (low-e layers) or with dynamic IR coatings like VO 2 . Here, our baseline includes low-e layers since the perovskite materials only modulate visible wavelengths and it is a more meaningful comparison when choosing new-build or retrofit window options.…”

“…An ideal T C has been suggested to range between 10 and 28 °C based on various reports in the previous decade that typically study simplified buildings and glazing systems (savings reported relative to single-pane windows) and in single climate locations. [5,9,10] Significant research has thus been put into reducing the T C of VO 2 with success in reaching T C < 30 °C by using nanostructuring or doping. [11] However, reducing T C slows the transition kinetics by decreasing the thermodynamic driving force and results in a larger hysteresis width due to the nature of the first-order phase transformation of VO 2 .…”

Urban centers across the globe are responsible for a significant fraction of energy consumption and CO2 emission. As urban centers continue to grow, the popularity of glass as cladding material in urban buildings is an alarming trend. Dynamic windows reduce heating and cooling loads in buildings by passive heating in cold seasons and mitigating solar heat gain in hot seasons. Here, reduced energy consumption in highly glazed buildings in a mesoscopic building energy model is demonstrated when thermochromic windows are employed. Savings are realized across eight disparate climate zones of the United States. The model is used to determine ideal critical transition temperatures of 20–27.5 °C for thermochromic windows based on metal halide perovskite materials. Ideal transition temperatures are realized experimentally in composite metal halide perovskite films composed of perovskite crystals and an adjacent reservoir phase. The transition temperature is controlled by cointercalating methanol, instead of water, with methylammonium iodide and tailoring the hydrogen‐bonding chemistry of the reservoir phase. Thermochromic windows based on metal halide perovskites represent a clear opportunity to mitigate the effects of energy‐hungry buildings.

Recently, the influence of building skin on daylighting performance has attracted great attention. therefore, many countries have adopted the retrofitting strategy for existing buildings to improve efficiency, the main concern of this work is to improve daylighting performance inside a classroom in a public school in Cairo, through a retrofitting strategy. Multi-Objective Optimization (MOO) framework and Genetic algorithms methodology will be adopted to optimize daylighting performance. The investigations were carried out via the use of "Ladybug and Honeybee" which could gather many simulation engines, Radiance & Daysim will be adopted for daylighting computation, integrated with Rhino & Grasshopper for 3D parametric modeling, and with Octopus plug-in as a (MOO) tool. The investigated building was designed by the General Authority of Educational Buildings, representing an example of southern oriented classroom prototype in Cairo. Daylighting performance was evaluated by using Dynamic Daylighting Performance Metrics as objective parameters. three variables for shading units' configurations were suggested as solution parameters, these variables were: shading units' number of slats rows, depth, and inclination angle. Results indicated that the base case has sufficient daylighting level while suffering from nonuniformity and discomfort glare. The suggested shadings resulted in a 91% reduction in the area exposed to direct sunlight, as it reduces the aSE 1000/250h on the occupied area from 31.5 % in the base case to 2.7 %, which is classified as a preferred value. Besides, helped efficiently in reducing glare probability and at the same time keeps the SDA 300/50% within preferred limits.
