MONTE CARLO-BASED SENSITIVITY ANALYSIS APPLIED TO BUILDING ENERGY ANALYSIS

Tóm tắt

This paper presents a technique used to examine the sensitivity of the output of a building energy model with respect to the variation of different design variables. The Monte Carlo-based sensitivity analysis was applied and a case-study house was used to demonstrate this technique. The paper carefully describes the process through which the Partial Correlation Coefficient of each design variable was calculated. Under the climate of Danang, the results of this analysis showed that in naturally ventilated dwellings, the building envelope and ventilation strategy are the most influential factors; meanwhile, the building envelope, the thermostat of HVAC systems and internal heat sources are significant in air-conditioned home. Sensitivity analysis can help designers to quickly choose appropriate solutions for their design problem and is useful for making choices in building renovation or retrofit.
