The global energy crisis has intensified due to increased demand and depleted resources, compelling people to reduce energy usage and switch to renewable sources. Accelerating the global decarbonization trend, many organizations and private citizens are finding ways to shrink their carbon footprint and transition to cleaner energy. For commercial buildings, an effective way to do both is by installing an energy-efficient heating, ventilation and air conditioning (HVAC) system. The latest HVAC systems not only cut energy consumption and costs, but also create a comfortable indoor environment that supports the well-being of tenants and visitors, leading to positive business outcomes and sustainable building operation.
