Rensair: A best-in-class connected technology hacks down the cost of running existing HVAC systems, cleans the air and makes indoor environments healthier places to be. No more high investment costs – we deliver a step-change in how buildings and spaces are ventilated. Carbon emissions and energy costs are rising quickly, as are the risks to our health through pollutants in our most important indoor spaces. HVAC systems can’t keep up, and they’re too expensive to replace, so we’re hacking HVAC to address the climate crisis and usher in a new era of carbon efficiency, cost savings and clean indoor air. Together, we can reduce global carbon emissions by 6.5%, the more space an organisation occupies, the greater its need for HVAC, leading to higher bills and a bigger carbon footprint. It’s an incredibly difficult problem, one that traditional ventilation systems were never designed to solve. That’s why Rensair has developed best-in-class hardware and software to hack HVAC and improve the energy efficiency of these indoor spaces, radically lowering carbon output. Our extensive research on emission levels and space optimisation proves we can decarbonise organisations’ real estate, and make a big difference to the planet.
