The application of the EN ISO 52016 standard and its Italian National Annex to assess the heating and cooling needs of a reference office building

The EN ISO 52016-1 standard presents a new simplified dynamic calculation procedure, whose aim is to provide an accurate energy performance assessment without excessively increasing the number of data required. Italian National Annex 52016-1, currently under development, provides some improvements hourly method; despite many works can be found in literature on model Annexes application has not been sufficiently analysed yet. present work assess main introduced by and compare results, terms need for space heating cooling. To this purpose, existing building representative office stock Northern Italy was selected as case study. simulations were carried out considering both continuous reduced operation HVAC systems. options specified firstly applied one one, then all together. variation compared international base procedure finally quantified. For premises scope above discussed, intended enhance standardisation activity towards adoption more trustable methods performance.
