Sustainable Ventilation Strategies for a Medium-Sized Space with Regional Effect

The analysis of ventilation strategies is fundamentally affected by regional climate conditions and local cost databases, in terms energy consumption, CO2 emission cost-effective analysis. A systematic approach covered this paper to estimate a economic environmental impact on medium-sized space located two regions during supply-and-installation operation phases. Three strategies, including mixing (MV), displacement (DV) stratum (SV) were applied air-conditioned with approach. trend the results for three systems life cycle assessment (LCA) (LCC) SV < DV MV. result LCC shows that lowest one both studies. In comparison Hong Kong Special Administrative Region (HKSAR) 20 Service years, case demonstrates percentage differences MV, & Guangdong are less than 20.5%, 19.4% 18.82% respectively. Their more HKSAR 10.69%, 11.22% 12.05%, present study could provide information about effects LCA emissions, thereby help set up models decision-making high efficiency strategy plans.
