“…This is in tandem with what is obtained through questionnaire surveys. Again, mature bamboo with good tensile strength could be reused two to three times since studies have shown that termites do not eat even untreated bamboo (Mir, 2013) thereby reducing the cost of construction further. This agreed with the findings of other investigators that suggested that bamboo is good as a building material given its high strength and less cost (Bagchi, et al, 2018).…”

“…Though, this may depend on the quality of erection or installation of the scaffold and prop. According to Mir (2013), bamboo is a wonderful grass that can replace other costly building materials because of its economy, serviceability, and Safety. Again, the cost of an assemblage of scaffoldings and props made of different materials could increase the cost of one over the other since specialists are involved.…”

The increase in demand and consequent high cost of steel props and scaffolds as a result of the desire to construct buildings with multiple floors in Nigeria has made many contractors use different materials. Thus, this study surveys and compares Steel, Timber and Bamboo scaffolds and props in Nigeria; it specifically investigated material preferences and their cost implications. It also determined installation techniques and the safety of props and scaffolds. Opinion surveys including questionnaire, visual inspections, interviews, and cost analyses were adopted as the research methodology. 50 ongoing building projects in Delta, Anambra, and Edo States were studied. The sample population was 30 site supervisors and 50 prop and scaffold installers. Purposive sampling was used to collect data. The findings reveal that contractors now prefer bamboo to other materials; the joinery systems depend on the material; nailing and tying for bamboo to bamboo while nailing and mechanical accessories were used for timber and steel respectively. Others are, all the materials are safe if properly fabricated and installed and the cost of scaffoldings and props decreases exponentially from steel to timber and then bamboo. Therefore, it was recommended among other materials that bamboo should be used in the production of prop and scaffold to save cost. Again, bamboo construction techniques should be included in the building construction curriculum, especially in scaffold and prop production.

“…To meet students' lifestyle and recreational needs, balconies are commonly incorporated into the floor plans of student dormitories. Balconies can be categorized into different types, such as recessed, projected, and composite [3,4], Projected balconies and composite balconies, due to structural constraints, should not exceed a length of 1.8 m. Therefore, in the study of balcony depth, recessed balconies hold more practical significance. Balcony Buildings 2024, 14, 1446 2 of 14 design in cold regions poses a multi-objective optimization challenge, as various factors interact and influence each other [5,6], which is a typical multi-objective optimization problem [7][8][9].…”

Thermal comfort and daylighting are vital components of dormitory environments. However, enhancing indoor lighting conditions may lead to increased annual energy consumption and decreased thermal comfort. Therefore, it is crucial to identify methods to reduce buildings’ energy costs while maintaining occupants’ thermal comfort and daylighting. Taking the dormitory building of Songyuan No. 2 at Shandong Jianzhu University of Architecture, which is located in a cold region, as an example, a field measurement analysis was conducted on the recessed balconies within the dormitory. The measured data were analyzed and utilized to simulate the annual energy consumption, thermal comfort predicted mean vote (PMV), and useful daylight illuminance (UDI) values of the dormitory units using the Grasshopper platform with the Ladybug and Honeybee plugins. The different depths of the balconies and window-to-wall ratios have a significant impact on the indoor physical environment and energy consumption, leading to the design of independent variables and the construction of a simplified parametric model. The simulation results underwent multi-objective optimization using genetic algorithm theory through the Octopus platform, resulting in a Pareto optimal solution set. Comparisons between the final-generation data and simulations of the original Song II dormitory unit indicate potential energy savings of up to 2.5%, with a 25% improvement in indoor thermal comfort satisfaction. Although there was no significant improvement in the UDI value, all the solution sets meet the minimum requirement of 300 lux specified by relevant regulations, according to the simulated average illuminance levels on the indoor work plane. Finally, the 60 optimal solution sets were further screened, filtering out sets deviating excessively from certain objectives, to identify 6 optimal solutions that are more balanced and exhibit a higher overall optimization rate. These findings offer detailed data references to assist in the design of dormitory buildings in cold regions.

Home Balconies during the COVID-19 Pandemic: Future Architect’s Preferences in Lisbon and Warsaw

The COVID-19 pandemic lockdowns altered people’s perception of the relationship between indoor and outdoor living spaces, pushing the home balcony concept into new levels of ambiguity. Particularly in European contexts, people’s perspectives on its existence, functions, features, and borders are now unclear territory. Therefore, our study intends to assess the balcony design features and activities during pandemic times through the lens of selected key informants’ preferences in Lisbon and Warsaw, resorting to a post-occupancy evaluation of an online survey and a subsequent statistical analysis using a Mixed Model Analysis of Variance. Differences in cultural/social background, climate, and geography appear to be irrelevant during the pandemic, as both locations’ respondents show similar outcomes concerning balcony preferences. Activities previously practised elsewhere are now preferential to occur on balconies, such as having meals, gathering people, or reading and writing. The study concludes that the importance of home balconies increased during the pandemic, demanding an update of its design features to accommodate the newly rediscovered activities with direct implications on its users’ health and life quality.
