Energy modeling: warehouse heating systems

Print page

Overview:
Space heating and lighting consume most of the energy in non-refrigerated warehouses. Installing more efficient lighting to save electrical energy has been well documented by computer modeling. But what about energy modeling guidelines for selecting more efficient gas-fired heating/ventilating equipment that accounts for 75% to 95% of the gas used at these facilities?

This white paper summarizes the approach, results and conclusions of the first published energy modeling analysis documenting predicted energy performance for six types of gas-fired heating systems commonly used in warehouses and commercial/industrial buildings with large open spaces. The computer simulation analysis includes a comparison to the ASHRAE 90.1 baseline heating system used to determine utility rebates, government tax deductions, energy points for LEED-certified buildings and other incentives for using energy-efficient heating equipment. A set of best practices guidelines is provided at the end of the paper.
