Hot Desk is a new prototype design that demonstrates how radiant hydronic heating can be integrated in modular mass timber construction. The CNC manufacturing protocols developed by the team allow radiant hydronic systems providers, building contractors, developers, and mass timber manufacturers to automatically mill and guide the specific thermal geometry of hydronic PEX tubing in structural or cladding panels. This can reduce or eliminate the costs of on-site labor and construction in radiant hydronics while enabling these efficient heating systems to be easily adapted to any layout.
