We have been working to adapt background oriented schlieren (BOS) imaging to directly visualize building leakage, which is fast and easy.

The traditional window installation process involves many steps. These are becoming even more complex with newer construction requirements such as installation of windows over exterior continuous insulation walls.

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.

Making existing buildings more airtight is critical in reducing the nation's energy consumption and carbon output. Most current methods of locating building leakage sites are disruptive to occupants and none of the methods can measure the flow of individual leakage sites.

Building Science Advisor is a web-based tool that allows users to quickly and reliably evaluate the moisture durability of their building wall designs and select the most energy-efficient and moisture-safe design.

This solid-state thermal switch can significantly increase the functions of the thermal mass in buildings by actively controlling the thermal resistivity of insulation layers to optimize the energy storage and utilization to shed, shift, and shape HVAC loads on demand.

The interface gasket for building envelope is designed to enhance the installation of windows and other objects into building openings.

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).
