Greentown Labs, the largest climatetech startup incubator in North America, Saint-Gobain, a multinational manufacturer and distributor of high-performance materials, and the Massachusetts Clean Energy Center (MassCEC), an economic development agency dedicated to accelerating the growth of the clean energy sector across the state, recognize the significant role healthy buildings will play in improving the sustainability of the built environment and promoting occupant wellbeing. That's why today, Greentown Labs and Saint-Gobain, with support from MassCEC, have launched the Greentown Launch Healthy Buildings Challenge, seeking applications from startups with buildings-related technologies that optimize for the health of people and the climate, together.
