The role of specific heat capacity on building energy performance and thermal discomfort

The key role of the building and construction sector, in terms sustainability decarbonization, has led codes to tighten mandatory requirements related buildings energy performance. Envelope quality, beyond light efficiency or renewable contribution, is a factor since highest percentage consumption produced by thermal losses through enclosures. Therefore, have significantly increased benchmarks for equivalent transmittance. However, specific heat capacity (SHC) commonly been overlooked discussion. Thus, order estimate impact such parameter comfort residential non-residential buildings, model simulated means Transfer Functions Methods Finite Difference Methods. A traditional double brick façade considered SHC bricks varied from 800 1800 kJ/kg K. behavior assessed at several locations accordance with Spanish code. In addition, orientation also shifted north south. Although passive strategies not considered, results show significant savings (i.e. up 20%) reduction discomfort 20%), depending on type its location.
