The heating, ventilation, and air conditioning (HVAC) system consumes a lot of electricity in the building to meet the demand for thermal comfort. The energy recovery ventilator (ERV) has been used in commercial, industrial, and residential buildings to save energy consumption for HVAC systems. In this study, we investigated the efficiency of ERV systems in different construction climate zones in Vietnam and the energy consumption of the sample primary school.

Stictic acid, a depsidone in many lichen species, is a potentially bioactive compound. Derivatives of stictic acid were synthesised by halogenation or esterification. However, the effects of these conditions on the decomposition of stictic acid have yet to be studied. Hence, the modification of stictic acid was investigated using an AlCl3 catalyst and dimethylformamide solvent.
