Evercloak develops a refrigerant-free building dehumidification system based on a proprietary graphene-oxide composite membrane that lets water vapour pass while blocking air. The membrane separates dehumidification from cooling, reducing the energy required to dehumidify and subsequently cool air; the company says this can improve building cooling efficiency by up to 50%. Evercloak is scaling membrane production and building an advanced dehumidification prototype as part of a NYSERDA-funded pilot, with an initial US$350,000 award and a potential US$1.15M extension for full-scale development and demonstration. The company estimates its technology could reduce emissions in the State's building sector by 40%, cut peak energy consumption by 25%, and eliminate two‑to‑five megatonnes of CO2 equivalents per year. Evercloak is actively partnering with HVAC manufacturers to rapidly deploy its systems globally and aims to commercialize the technology through demonstrations in New York City buildings. The company frames its product as a market-first building dehumidification technology to improve indoor comfort while lowering greenhouse-gas emissions. Evercloak develops graphene-composite membranes and a patented manufacturing process for continuous single-layer nanomaterial coatings aimed at membrane-based dehumidification. Its HVAC solution radically reduces the electricity needed to dehumidify air, which the company says can cut air-conditioning energy demands in half. Field trials of two demonstration units in summer 2023 demonstrated performance, and the company is preparing to bring the solution to market. With an oversubscribed $2M seed round, Evercloak plans to scale up membrane manufacturing and strengthen its commercial team. The firm positions its technology as a critical efficiency lever amid rising cooling demand and international pledges to reduce emissions from cooling systems. Based in Waterloo, Ontario, Evercloak says its nano-coating manufacturing approach can also be applied to energy storage, water desalination and other industrial processes.
