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.

lectric Arc Furnace Dust (EAFD) and wasted glass are two types of waste in industry and daily life, so they must be recycled to recover some useful elements. The production of colored glass is one of the methods used to recycle the electric arc furnace dust to take advantage of the coloring element in the dust. To use this colored glass for decoration, it is also necessary to test its durability. The present study focuses on the properties of colored glass when using electric furnace dust.

Lead-free barium titanate based Ba1-xSrxTiO3 thin films (x = 0 ÷ 0.45) have been deposited onto Pt/Ti/SiO2/Si(100) substrate via sol–gel technique. The films were crystallized at temperature of 650 °C for 30 min in the air. The experimental data displayed that microstructure, dielectric and ferroelectric properties of the films were strongly influenced by the Sr concentration.
