We deliver detailed cooling and heating load assessments to establish the appropriate HVAC capacity for each building, considering architectural characteristics, building envelope performance, occupancy profiles, lighting, equipment loads, ventilation requirements, and local climatic conditions. Using industry-recognized tools such as Carrier HAP, IES VE, DesignBuilder, and Autodesk Revit for BIM coordination, we perform room-by-room and zone-based analyses in accordance with applicable ASHRAE standards and project requirements. Our calculations provide a reliable basis for equipment selection, system sizing, energy-efficient design, and coordinated mechanical engineering documentation.
