Compliance with BS EN ISO 52016-1

Compliance with BS EN ISO 52016-1

EDSL has produced a report showing compliance with the current standard BS EN ISO 52016-1:2017.

The standard contains details of test case setup, and tables of values for expected results for operative temperature, heating load, and cooling load. The test cases included conditioned and free-floating cases.

Unlike some other standards, 52016-1 does not specify an acceptable margin for software results compared to the target.

The Tas results showed good agreement with the results expected by the standard.

The Tas software’s compliance with this standard means users can have confidence in the accuracy of the TBD simulation engine.

.. are superseded. But their test cases are still a useful test of the validity of software results and, unlike 52016-1, they specify acceptable margins for software results.

Validation of Tas against BS EN ISO Standards

Posted on

The BS EN ISO Standards 13791, 13792, 15255, and 15265 are used to validate a building simulation software’s results against expected results; compliance with these standards demonstrates the integrity of the simulation engine as the results are concerned with the solar, heat flow, and room load calculations which underpin the annual simulation.

Models were set up in Tas to the requirements specified in the standards. In each case Tas results fell within the standards’ specified margin of the expected results.

BS EN ISO 13791 tests heat conduction, long-wave radiation, surface sunlit factors, and operative temperatures resulting from different geometry, constructions, and ventilation methods.

BS EN ISO 13792 tests surface sunlit factors, and operative temperatures resulting from different geometry, constructions, and ventilation methods.

BS EN ISO 15255 tests operative temperatures and cooling loads resulting from different constructions, gains, ventilation methods, and cooling systems.

BS EN ISO 15265 tests heating and cooling loads resulting from different geometry, constructions, gains, and system schedules.

The Tas software’s compliance with these standards means users can have confidence in the accuracy of the TBD simulation engine.
