Asphaltic Plug Joints for Bridges: Material Requirement, Construction, and Testing
Asphaltic plug joint (APJ) is a type of bridge expansion joint that is a simple general-purpose expansion device for bridges having a total motion of less than 50 mm (2 in). These joints are used in joint expansion sealing on ...
Phase Change Materials (PCMs) for Building Applications
Phase-change materials (PCMs) possess high storage density in a narrow temperature interval. They release or absorb sufficient energy at phase transition (solid to liquid or vice versa) to provide useful heat or cooling. PCMs are used to enhance the thermal ...
Basic Principles to Achieve Net-Zero Energy Buildings (NZEB)
A net-zero energy building (NZEB) can be defined as a building that produces as much energy as it consumes when measured at the site. These buildings provide high performance by taking a significant amount of energy from renewable sources produced ...
