| BSI | 2018 | 144 |
This document contains information to support the correct understanding and use of ISO 52016-1 and ISO 52017-1.
These documents give calculation methods for the assessment of:
-
the (sensible and latent) energy load and need for heating and cooling, based on hourly calculations;
-
the (sensible and latent) energy need for heating and cooling, based on monthly calculations (ISO 52016-1);
-
the internal temperature, based on hourly calculations; and
-
the design (sensible and latent) heating and cooling load, based on hourly calculations.
This document does not contain any normative provisions.
NOTE A description of the rationale behind the reorganization of the cluster of strongly related and partly overlapping ISO and CEN standards is given in Annex H.
