We have been working to adapt background oriented schlieren (BOS) imaging to directly visualize building leakage, which is fast and easy.
Commercial closed-cell insulation foam boards reduce their thermal resistivity by up to 30% due to gas diffusion in and out of foam cells.
Concrete floor slab flatness and levelness are parameters often specified in construction documents that contractors must meet to ensure a high quality of construction. However, the measurement of these parameters is cumbersome and time-consuming.
Application of thermally anisotropic composite materials coupled with a heat sink/source can redirect and reduce heat flows through a building envelope (walls and roofs).
