Among other energy savings policies, European Directive 2018/884 promotes the adoption of building energy audits. In this perspective, the development of accurate, but simplified dynamic energy simulation tools is a fundamental step to reduce the costs of energy audits and consequently increase their diffusion, especially at the professional level. This paper presents SEAS Light, a simplified dynamic tool that estimates building heating and cooling energy demands. 75 test cases associated to typical Italian climates and building structures have been performed. SEAS Light results are compared with the ones obtained through the full dynamic energy software TRNSYS 17. The validation procedure shows that the proposed routine can evaluate both seasonal heating and cooling energy demands with a good accuracy, using three tuning coefficients presented in the manuscript.

Abstract
Among other energy savings policies, European Directive 2018/884 promotes the adoption of building energy audits. In this perspective, the development of accurate, but simplified dynamic energy simulation tools is a fundamental step to reduce the costs of energy audits and consequently increase their diffusion, especially at the professional level. This paper presents SEAS Light, a simplified dynamic tool that estimates building heating and cooling energy demands. 75 test cases associated to typical Italian climates and building structures have been performed. SEAS Light results are compared with the ones obtained through the full dynamic energy software TRNSYS 17. The validation procedure shows that the proposed routine can evaluate both seasonal heating and cooling energy demands with a good accuracy, using three tuning coefficients presented in the manuscript.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
