“…Green buildings are typically defined as structures that protect the environment and resources efficiently throughout a building's life cycle by carefully considering aspects such as design, construction, maintenance, operation, repair, and rehabilitation. The concept of "green building" has gained popularity and spread worldwide in recent decades, focusing on issues such as global warming, unpredictably changing monsoons, and controlling emissions from the construction industry [14]. The traditional construction method assumed that GHG were only emitted when fossil fuels were used directly for heating and electricity.…”

Green building is a way to reduce the impact of the building stock on the environment, society, and economy. Despite the significance of a systematic review for the upcoming project, few studies have been conducted. Studies within the eco-friendly construction scope have been boosted in the past few decades. The present review study intends to critically analyse the available literature on green buildings by identifying the prevalent research approaches and themes. Among these recurring issues are the definition and scope of green buildings, the quantification of green buildings’ advantages over conventional ones, and several green building production strategies. The study concludes that the available research focuses mainly on the environmental side of green buildings. In contrast, other crucial points of green building sustainability, such as social impacts, are often neglected. Future research objectives include the effects of climate on the effectiveness of green building assessment methods; verification of the actual performance of green buildings; specific demographic requirements; and future-proofing.

“…8 Therefore, lightweight, environmentally friendly, fire-resistant, and low thermal conductivity materials are required for insulation applications. 9 Recent studies have focused on foams partially or wholly produced from biopolymers due to their low CO 2 footprints. 10 Cellulose is a natural polymer consisted of glucose units and is the primary structural component of the cell walls of plants.…”

The study developed and designed polyvinyl acetate (PVAc) foams using advanced freeze-drying technology, which exhibited good heat-insulating ability, flame retardancy, and mechanical properties. Different combinations of bleach kraft pulp, water-soluble chitosan, and zinc borate were used to reinforce the foams. The foams exhibited desirable compression and flexural properties, with compression strength and compression modulus ranging from 0.01 MPa to 0.08 MPa and 0.05 MPa to 0.29 MPa, respectively, while flexural strength and flexural modulus ranged from 0.12 MPa to 5.37 MPa and 9.86 MPa to 260,85 MPa, respectively. The use of zinc borate as a reinforcement resulted in improved thermal properties and reduced mass loss at 600°C by 20.69%. Thermal conductivity tests indicated that the foams had low thermal conductivity values ranging from 0.037 W/mK to 0.074 W/mK. The foams with zinc borate (60 g/L) and high molecular weight water-soluble chitosan (70 g/L) reinforcement exhibited high limiting oxygen index (LOI) of 28.72%. Overall, the results suggest that the PVAc foams could serve as a promising sustainable alternative in thermal insulation and construction fields.

“…The massive pollution caused by these products has greatly increased people's environmental concerns (Bülbül and Ergün 2022). In addition, common insulation materials present a high risk in indoor applications because of their easy flammability (Yildirim et al 2020). Considering all of these issues, many researchers have focused on producing from renewable resources because they have attractive properties, such as biodegradability, recyclability, environmental acceptability, and sustainability (Qiu et al 2013).…”

Chitosan foams with promising mechanical properties, heat-insulating ability, and flame retardancy were produced through oven drying. The chitosan foams were reinforced with cellulose, boric acid, and different ratios of activated carbon. The foams showed desirable low density (80.2 to 109.8 kg/m3) and compression properties. The compression resistance and compression modulus of foams ranged between 53.6 and 98.5 KPa and 214 to 394 KPa, respectively. Thermal conductivity tests revealed that the foams endowed low thermal conductivity values (0.035 to 0.051 W/mK). The limiting oxygen index (LOI) of the foams was as high as 32.9% for activated carbon (20 g/L). The activated carbon reinforcement produced higher thermal properties and decreased the mass loss 48.1% at 600 °C. The produced foams exhibited good biodegradability (39% degradation in 15 days). The overall test results showed that the chitosan foams can be utilized as a promising environmentally friendly material in thermal insulation fields.
