About this file
This is an HVAC load calculation document prepared by R.W. Kicklighter HVAC Consulting for the Seville Village Improvement Association Historic Gym project located at 1591 US Highway 17, Seville, Florida. The document provides detailed commercial load calculations for the gymnasium facility using Right-Suite Universal 2024 software and establishes the technical specifications for the required HVAC system. Based on comprehensive thermal analysis including glazing solar heat gain, transmission gains through walls and ceilings, internal heat generation from occupants, infiltration, and ventilation requirements, the consulting engineer determined a total cooling load of 357,724.75 BTU per hour and a heating load of 208,861 BTU per hour. The calculation recommends installation of ten 3-ton ductless mini-split units to meet the facility's climate control demands, with unit placement to be determined prior to installation in coordination with the selected HVAC contractor. The calculation was completed on July 29, 2025, and serves as the technical basis for the competitive bidding process scheduled for November 13, 2025.
The load calculation accounts for design conditions including outdoor temperatures of 91°F for cooling (with 53% relative humidity) and 40°F for heating, with indoor design conditions of 75°F and 63°F wet bulb for cooling and 70°F for heating. The analysis incorporates structural characteristics specific to the historic building, including assumptions of no existing ceiling or roof insulation and recommended spray foam insulation upgrades to walls achieving R-13 value. Supply duct heat gain of 16,751 BTU/hr and return duct heat gain of 15,871 BTU/hr are factored into the total equipment loads, resulting in total cooling loads of 230,172 BTU/hr on equipment and total heating loads of 208,861 BTU/hr. The consulting engineer commits to working with the selected installing HVAC contractor to ensure adequate coverage and proper distribution of cooling capacity throughout the gymnasium space. This technical documentation supports the federal CDBG-CV funding mechanism and establishes the performance baseline for contractor bid evaluation and post-installation system performance verification.
