HVAC

HVAC (Heating, Ventilation, and Air Conditioning) systems are the mechanical infrastructure that regulate the thermal comfort, air quality, and humidity within buildings, representing one of the most significant determinants of occupant wellbeing, energy consumption, and environmental performance in the built environment. While often hidden within ceilings, walls, and building service cores, HVAC design has profound spatial and architectural implications — determining ceiling heights, structural bay sizes, facade performance requirements, and the overall energy strategy of a building. The relationship between architecture and HVAC has become central to sustainable design, as architects and engineers work to minimize the mechanical load on buildings through passive strategies — natural ventilation, thermal mass, shading, and building orientation — that reduce dependence on energy-intensive active systems, connecting mechanical engineering to the broader agenda of sustainable architecture and passive house design.
