“…Windows are a significant part of a building's façade, and while they typically represent a smaller area than the external opaque walls, they generally lose a greater amount of heat. Research about the function of windows discussed a case study building wherein the windows accounted for only 14% of the total external walls and roof area, while the heat loss from the windows was 48% of the total loss [29]. Upgrading to triple-glazed windows is a high efficiency retrofit measure that improves the thermal performance, and visual and acoustic comfort, as well as decreasing the condensation risk and air leakage [27].…”

Retrofitting buildings to achieve improved levels of energy performance is a key strategy in the transition to a low-/net zero carbon future. In China, there has been an enormous growth in residential construction in recent decades in response to the country’s economic development and population growth. However, although these buildings are structurally solid and have long functional life spans, most have very poor thermal performance. Therefore, they would be very suitable for energy retrofitting. Because of the variety of retrofitting options, it is important to review the retrofit measures, regulations and possible outcomes to find effective, long-term solutions that strike a balance between the energy saved, the carbon emitted and the financial costs over a building’s lifetime. This paper reviews suitable retrofit measures for the hot summer–cold winter region of China, because this is an area with huge numbers of residential buildings that are suitable for energy retrofitting. The study explores the current conditions of targeted residential buildings, retrofit schemes, building regulations, and policy gaps towards achieving China’s 2060 carbon neutrality goal. The review indicates that current mandatory building energy regulations in this region are not ambitious enough to achieve a significantly lower carbon future, and one-step deep Passivhaus retrofit schemes are recommended to achieve decarbonization goals.

“…Despite expanding investigation endeavors, it isn't however prudent to partition the wide assortment of plastics that end up within the squander stream. The perfect is streams of single, clean, and homogeneous recyclates, which show small specialized exertion for reusing [15,16,17]. A normal reusing course for squandering plastics can be part of two sorts of processes, one physical or mechanical treatment to plan and homogenize the squander, and the second dissolving.…”

The administration and management of waste is one of the major issues confronting the advanced society and is not fairly constrained to plastics. The squandering or waste generated annually is by and large a claim in Pakistan. Reusing plastic is required to support the environment. The wall panels that are utilized in interiors are made up of Polyvinyl chloride (PVC) which is harmful and there are few chances to diminish the poisons from it. Moreover, they are not perfect insulators and are very expensive. The work aims to utilize plastic squander into wall panels made of reusing Polyethylene Terephthalate (PET) which are aesthetically pleasing, economical, easy to maintain and of high quality. The method incorporates case studies and surveys to find out the finest manufacturing and fabricating process. The experiment phased in product specification along with drawings, rendering, prototyping and finally recycling plastic into the final product. The conductivity of the material is raised by using blisters with a silver coating which raised from 5% to 10% and a vacuum is also created between the panels. The compressive strength is tested which is 80.5 MPa. If the product is made on a large scale, it will help in reducing plastic waste.

“…Various studies have shown that energy-efficient retrofitting measures include the replacement of conventional lighting fixtures with energy-efficient ones (Kaewunruen et al, 2019), applying window shading (Ahmed & Asif, 2020), the use of glazed glass, and improving airtightness (Urbikain, 2020). The use of an energy-efficient air conditioning system (She et al, 2018) and adding building envelope insulation are also among the eight energy efficiency measures (EEMs) that can reduce energy use by up to 60% (Pohoryles et al, 2020) and CO 2 emissions by up to 30% (Kamal et al, 2019).…”

This work aims to reduce the energy consumption of existing buildings through retrofitting and converting them into net zero energy buildings (NZEBs). Various retrofits for an existing academic building were modeled and analyzed using REVIT software. Energy consumption was reduced to approximately 34% through retrofits, and a Solar System of 41.6 kW was integrated to meet the reduced energy demand, consequently converting the building into an net zero energy building (NZEB). Furthermore, environmental and economic analyses were conducted, and the results show a reduction of 32.8 metric tons of CO2 emissions per year as a result of retrofitting the building, converting it into an net zero energy building. The building envelope retrofits and electrical appliances have a payback period of 2.96 and 2.62 years, respectively, whereas the proposed Solar System has a payback period of only 2.3 years. Moreover, the building was rated using the Leadership in Energy and Environmental Design (LEED) rating tool, and it qualifies for silver certification after retrofits and the integration of renewable energy sources (RES). The reduction in energy consumption and integration of renewable energy sources contribute to achieving Sustainable Development Goal (SDG) 7, and reduced CO2 emissions save climate variations, which leads to achieving Sustainable Development Goal 13.
