HVAC elements modeling and implementation for net-zero energy building applications

It is well known that rising energy prices have lead scientists to focus a special attention over resident or commercial building energy efficiency. Recent advances in digital technologies also encourage the development of a wide range of HVAC (Heating, Ventilation and Air Conditioning) automation systems for “net-zero energy building” strategies implementation. In topic with these emerging trends, this paper presents the modeling and software implementation research efforts of several HVAC elements, as basic components of a specially conceived “intelligent house” at Debrecen University. These components have been designed to overcome same of the actually existing deficiencies and emptiness in the HVAC systems modeling and simulation processes. Their original models have been implemented as novel VI (Virtual Instruments) by using the graphical oriented LabView software toolkit. Beside the elaborated mathematical models concrete software implementation examples are provided in the paper. These models are suited to become a useful software toolkit for implementing HVAC systems for net-zero energy building approaches, offering a feasible solution for future developments and research.
