Abstract: Waste heat from an industrial facility is used as a heat source for a 3-acre greenhouse on site. Preliminary calculations for heat availability and simulation results demonstrate the feasibility of satisfying the entire heating load with the use of waste heat. This paper discusses the results of several greenhouse simulations using EnergyPlus. From the simulation results, the electrical heating energy consumption of a typical greenhouse heated by VAV system is compared to the electrical energy consumption of an innovative greenhouse utilizing water to air heat pumps to transfer heat energy from the waste heat to the greenhouse zones. The study concluded that there is a great potential for waste heat as a source for greenhouse heating with simulation results indicating that the WAHP system could reduce the annual heating electricity consumption from the 13,780 GJ consumed by the VAV system down to 5983 GJ.
