Data of high performance precast external walls for warm climate

Area of Science:

• Building Science
• Sustainable Architecture
• Thermal Engineering

Background:

• Achieving optimal performance in Zero Energy Buildings (ZEBs) in warm climates requires careful consideration of envelope properties, specifically superficial mass and internal areal heat capacity.
• Existing research highlights the importance of these factors for energy-efficient building envelopes.

Purpose of the Study:

• To investigate the feasibility of high-performance precast external walls for warm climates using lightweight and ultra-thin solutions.
• To conduct a multi-criteria optimization analysis considering thermal behavior, environmental sustainability, and cost.

Main Methods:

• Utilized the modeFRONTIER optimization tool integrated with computational procedures developed in Matlab.
• Assessed the thermal dynamics of building components through steady and dynamic thermal behavior analysis.
• Performed a multi-criteria optimization across thermal performance, eco-sustainability score, and cost.

Main Results:

• Demonstrated that high-performance precast walls are achievable even with light and ultra-thin construction.
• Identified optimal configurations balancing thermal efficiency, environmental impact, and economic factors.
• Generated a comprehensive dataset of the best-performing precast wall configurations.

Conclusions:

• Lightweight and ultra-thin precast external walls are viable solutions for high-performance buildings in warm climates.
• Multi-objective optimization effectively balances competing design criteria for building envelopes.
• The study provides valuable data for designing energy-efficient and sustainable precast wall systems.
