Which factor is crucial for the design of HVAC equipment placement?

The design of HVAC equipment placement must consider a variety of factors, with concealment from public view being particularly significant. This factor addresses both aesthetic and functional aspects of building design. Hiding HVAC systems from public view helps maintain the visual integrity of the building’s architecture and enhances the overall appearance. Moreover, it reduces noise pollution within occupied spaces and can help in protecting the HVAC units from vandalism or damage.

While considering the other factors, such as the availability of power sources, maximizing rooftop space usage, and minimizing installation costs, they are all important in their contexts but do not carry the same weight in terms of the immediate visual and experiential impact on the building's occupants and the general public. Concealing HVAC systems can lead to a more cohesive design, supporting the architect's goal of harmonizing all building elements.
