Building Science, Technologies and Systems

Building science integrates the study of materials, energy flows and systems interactions that govern the performance of the built environment. It spans the thermal, acoustic, mechanical and environmental disciplines required to design, construct, operate and retrofit structures for safety, durability, comfort and sustainability. Advances in cementitious composites, lightweight masonry, envelope technologies and energy-efficient systems have resulted in lower carbon footprints, improved indoor environmental quality and heightened resilience to climate extremes. Digital tools and sensor networks now provide real-time monitoring of building health, energy use and occupant behaviour, enabling data-driven control strategies and life-cycle optimisation. By combining passive measures—such as ventilated roofs, high-performance envelopes and low-emissivity coatings—with active systems including heat pumps, renewable generation and smart controls, contemporary practice aims for net-zero energy operation while maintaining occupant well-being and structural safety over extended service lives.

Study on fresh and hardened state properties of eco-friendly foamed concrete incorporating waste soda-lime glass. Investigators assessed the use of crushed bottle glass as a partial sand replacement in cellular foam concrete. They found that substituting up to 20 % by weight significantly improved compressive, flexural and splitting tensile strengths by up to 44 %, while enhancing thermal conductivity, reducing porosity and altering pore structure for more uniform void distributions. These findings demonstrate the dual benefits of recycling waste glass and upgrading foam concretes for exposed façade and infill applications.

Seismic performance evaluation of plastered cellular lightweight concrete block masonry walls. Researchers tested full-scale masonry wallets and prism specimens under cyclic lateral loading to gauge the benefits of confining elements. When block walls were tied with reinforced bands, lateral load capacity doubled and displacement ductility rose by over 5 %, compared with unreinforced masonry. The study validates the role of lightweight cellular concrete blocks combined with strategic confinement to deliver efficient, seismic-resilient load-bearing systems.

Global transition of operational carbon in residential buildings since the millennium. A bottom-up decomposition analysis covering 2000–2020 in 56 countries revealed that operational carbon intensity declined by 1.2 % per annum, driven chiefly by improved end-use efficiency in appliances, heating and lighting. Growing household floor areas partially masked per-square-metre gains—a “dilution effect” that delayed peak building energy intensity by over a decade. This large-scale assessment offers policymakers quantitative benchmarks for tailoring efficiency measures to regional consumption patterns.

Decarbonizing or illusion? How carbon emissions of commercial building operations change worldwide. Using index decomposition in sixteen markets, the study reported modest global growth of 0.9 % per year in commercial building emissions over 2000–2019, contrasted with sharp declines in the United States and rapid increases in China. Economic activity and efficiency gains accounted for much of this divergence, with Spain achieving nearly 30 % decarbonization efficiency. The findings underscore the need for targeted policies addressing both economic growth and energy-efficiency investments across diverse market contexts.
