“…Summarizing the results obtained with the proposed approach, interesting conclusions can be drawn. A first consideration can be made about climate; as already seen in previous studies [4,20,21], this parameter showed a great influence on energy consumption. What was not obvious was its impact on costs.…”

“…On the basis of their and other studies, they provided recommendations to help designers choose various elements. Sadeghifam et al [4] conducted a similar research. They considered different types of floor, walls, windows and ceilings, and through the Taguchi statistical method, they determined the level of importance of the building components in term of energy insulation, also considering the effects of noise factors such as temperature, humidity and air flow.…”

“…Hence, the building sector in urban areas is becoming increasingly energy consumptive. It has been estimated that even if all the energy efficiency policies are implemented with great success, global primary energy demand is still expected to increase by 35% by 2040 [4]. This scenario is generating growing concern regarding the impact that the building sector may have on the environment and what can be done to improve sustainability in this industry.…”

The building sector plays a central role in addressing the problem of global energy consumption. Therefore, effective design measures need to be taken to ensure efficient usage and management of new structures. The challenging task for designers is to reduce energy demands while maintaining a high-quality indoor environment and low costs of construction and operations. This study proposes a methodological framework that enables decision-makers to resolve conflicts between energy demand and life cycle costs. A case study is analyzed to validate the proposed method, adopting different solutions for walls, roofs, floors, windows, window-to-wall ratios and geographical locations. Models are created on the basis of all the possible combinations between these elements, enriched by their thermal properties and construction/management costs. After the alternative models are defined, energy analyses are carried out for an estimation of consumption. By calculating the total cost of each model as the sum of construction, energy and maintenance costs, a joint analysis is carried out for variable life cycles. The obtained results from the proposed method confirm the importance of a preliminary assessment from both energy and cost points of view, and demonstrate the impact of considering different building life cycles on the choice of design alternatives.

“…The major increase in energy consumption has led to other critical issues including supply shortage, energy resource diminution, and grave environmental effects such as ozone depletion, climate change and global warming. Despite rising demands against the exploitation of energy and natural resources, environmental and sustainability concerns remain a leading global issue (4).…”

“…In terms of energy usage, the main consideration is on the materials required for the main components and envelope of the building. According to Sadeghifam et al (2019), the energy intake for residential buildings in tropical areas can be significantly reduced by choosing the right components/materials for the ceiling, windows, walls, roof, and floor (4). A building would require high levels of cooling if the envelope has extreme heat transmission.…”

In the contemporary milieu of today, sustainability and environmental concerns have become a great subject of debate. Matters related to sustainability are often linked to other crucial concerns like energy consumption. Energy is a key factor in ensuring continuous economic growth and development. One of the highest energy consuming systems in buildings – specifically residential homes in tropical regions – is the air conditioning system. Windows have been identified as the weakest link in the fabric of a building as they serve as thermal holes. Thus, the selection of proper window materials is crucial to reduce energy usage by minimizing the cooling and heating requirements of the building. The aims of this paper are analysis of energy performance for diverse types of window’s glazing with different frames in order to find the most optimized window materials for the tropical residential buildings. The selected case study in this paper is modeled and then simulated by Building Information Modeling (BIM) application, which is appropriate for energy analysis. For simulation, some factors of the window materials were taken into consideration including, four physical properties of the U-factor, solar heat gain coefficient, visible transmittance, and emissivity. The result was shown windows types 02 and 03 were the most optimized of window materials and led to 10% energy saving into the base model and the windows type 05 was high U-factor, results in a greater transfer in internal zones and led to high energy consumption.
