Report of Case Study on EN ISO 52016-1 – Heating and cooling needs and internal temperatures
See introduction and links below.
Abstract
This document presents the case study on EN ISO 52016-1:2017, Energy performance of buildings — Energy needs for heating and cooling, internal temperatures and sensible and latent heat loads — Part 1: Calculation procedures.
The case study makes use of the spreadsheet tool that has been developed to demonstrate the calculation procedures and to perform example calculations.
One of the aims of the study is to show that the choice for hourly instead of monthly calculation procedures (both are covered in EN ISO 52016-1 and in the spreadsheet) does not require extra input data. On the contrary: the input and procedures (e.g. on the control of solar blinds, on the impact of undersized systems, on intermittent heating) is much more straightforward and the output is richer: e.g. includes a score on thermal comfort. Variations illustrate the sensitivity.
Also illustrated: the impact of less crucial but still influential details for which at national level one has to decide whether default values would be suitable or not.
Most of the work has been applied in the frame of webinars from the EPB Center, recordings of which are available under [5]. This document gives an overview.
