Modeling of heat and moisture transfer in building using RLF method

This study is concerned with effectiveness of building internal temperature and relative humidity by ventilation and infiltration flow rate. Building model is inevitable to study the feasibility of building ventilation, and how to affect on indoor air quality. The empirical method which used in building model is a residential load factor (RLF). RLF formed to calculate cooling/heating load depend upon indoor/outdoor temperature. The transparency, functionality of indoor/outdoor temperatures and simplicity of RLF make it suitable for use in this model. Furthermore the parameters of model can be calculated room by room and that´s proper for variable air volume (VAV). Today a VAV system is universally accepted as means of achieving energy efficient and comfortable building environment. The model what we get verified with different method, by manual or software program calculation.
