HVAC Sizing for Concrete Homes is an essential reference for any HVAC or concrete professionalDeveloped as part of a HUD-sponsored project, this software provides an alternative means of estimating heating and cooling system capacities for single-family concrete homes. The software calculates the system capacities based on the house dimensions, construction materials, location (U.S. and Canada) and thermostat set point. Based on U.S. Department of Energy 2.1E Calculation engine and various ASHRAE standards. A recent version of Microsoft Excel for Windows (such as Excel 97, 2000 or XP) is required.Insulated concrete walls are increasingly being utilized as an alternative to wood frame walls in residential construction. Insulated concrete walls include insulating concrete form (ICF) walls, cast-in-place insulated concrete walls, insulated precast concrete walls, autoclaved aerated concrete (AAC) walls, and insulated concrete masonry (CMU) walls. Houses constructed with concrete wall systems are both disaster resistant and energy efficient. Energy efficiency is imparted by the inherent thermal mass, high levels of insulation, and low air infiltration of these walls. Considerable work has been performed by a variety of researchers to compare the energy performance of concrete homes to that of wood framed alternatives. The consensus is that the inherent energy-saving properties of insulated concrete walls can result in HVAC equipment being downsized by as much as 15 to 40% in concrete homes in comparison to identical wood framed homes. |
