Demand Response Integration:

   High-performance HVAC systems can be integrated with demand response programs, allowing buildings to participate in grid management initiatives. During peak demand periods, when electricity prices are high or the grid is stressed, the HVAC system can automatically reduce its energy consumption or shift it to off-peak hours. This not only helps alleviate strain on the electrical grid but also provides cost savings to building owners by taking advantage of lower electricity rates during non-peak hours.

Noise Reduction:

   High-performance HVAC systems incorporate noise-reducing features to create a quieter and more comfortable indoor environment.
