Comparison Study of the Heating Energy Demand for a Multi-Storey Residential Building in Romania Using Steady-State and Dynamic Methods

Abstract

The purpose of this study is to determine the differences between the steady-state energetic method and the dynamic energetic method in a multi-storey residential building in Romania. For both methods, there are two values for the heating energy demand, one obtained with the theoretical U value and g value according to Romanian Methodology Mc 001/1-2006 and one with the real U value and g value obtained from in situ measurements. The results of our study revealed a difference between the steady-state method and the dynamic method in both cases of approximately 20%. Because the heating energy demand needs to decrease in value according to European legislation and the classical energy demand determination is shallow, as it does not take into account some important factors, it is important to use a method that produces accurate values so the economic factor does not become overwhelming.

Demand-Oriented Review of a Dynamic Energy-Loss Monitoring System for Primary School Buildings through Micro-Environmental Data Monitoring and Occupant Behavior Analysis

“…In recent years, simulation tools for calculating building energy consumption have proliferated. Nevertheless, these simulations assume steady-state operating conditions and their results do not accurately reflect building energy consumption [88][89][90]. With the advancement of data transmission and computer technology, however, more and more invisible, unmeasurable, and volatile data are becoming available.…”
