New York — As the summer heat intensifies across the country, the need for efficient cooling systems in commercial real estate has become paramount. Landlords are under pressure to meet high demand while managing rising operational costs, making energy efficiency a critical focus.
Many large buildings struggle with outdated systems that lack precise temperature control. These central systems often fail to accurately gauge the conditions in different areas, leaving office employees donning layers in summer while feeling uncomfortably warm in winter. This mismatch highlights the urgent need for smarter solutions.
Runwise, a New York-based tech startup, is addressing this issue with its innovative hardware and software platform designed to optimize heating and cooling in commercial buildings. Recently, the company expanded its focus to improving cooling efficiency, a move that aligns with growing climate goals and economic pressures to reduce unnecessary energy use.
Jeff Carleton, co-founder and CEO of Runwise, emphasized the environmental and financial impact of inefficient building operations. “Every unnecessary cycle of a boiler or air conditioner not only costs money but also contributes to carbon emissions,” he noted. The urgency to find solutions is compounded by the ongoing effects of climate change.
Runwise’s approach combines advanced weather forecasting algorithms with a network of wireless temperature sensors. This system communicates with a central control unit that analyzes real-time data to optimize building operations. In a typical 100,000-square-foot facility, instead of relying on a single boiler and traditional temperature feedback, Runwise deploys 20 to 25 sensors. This setup allows for more accurate assessments and more efficient running of heating and cooling systems.
With technology now installed in over 10,000 buildings across ten states, Runwise serves approximately 1,000 customers, including major players in real estate such as Related and Equity Residential. The company’s innovations have reportedly saved clients over $100 million in energy expenses.
Recently, Runwise secured $55 million in Series B funding, bringing its total financing to $79 million. This investment, led by Menlo Ventures and supported by a range of other investors, will drive the startup’s expansion and further integrate artificial intelligence into its operations.
Carleton shared his vision for the future of building management. “As we gather more data, we can develop increasingly sophisticated models that enhance our systems’ efficiency,” he said. The strategic incorporation of AI is expected to refine algorithms continuously and improve overall energy management.
In a time of rapid technological advancement and pressing environmental challenges, Runwise is positioned to lead the way in modernizing building systems. The company’s commitment to sustainability and efficiency may pave the path for more responsible energy consumption and a greener urban landscape.
