The home improvement market represents $150 billion in annual investment, with over 14 million projects that involve replacement or upgrades of heating and cooling systems, windows, siding and roofs, insulation and other measures.  HI Cat conducts R&D that catalyzes innovations in home improvement retrofit technologies and their integration with existing homes systems. HI Cat concentrates on new solutions and approaches for trade contractors to help homeowners take action to save energy and achieve additional benefits such as greater comfort, health, durability, and value.
