Abstract
It is common to assess the level of wasted energy due to the inappropriate selection of HVAC systems (Heating, Ventilation and Air Conditioning) that are regularly used to control temperature in man-made environments. The present work investigates the use of radiant panels as alternative method for controlling the thermal environment and aims to contribute to the characterization of the performance of these devices. It is a technology that has already proven its effectiveness in terms of cooling, however, still little explored for heating, particularly in spaces with high ceilings.

It is common to assess the level of wasted energy due to the inappropriate selection of HVAC systems (Heating, Ventilation and Air Conditioning) that are regularly used to control temperature in man-made environments
A numerical methodology was used for evaluating the convective and radiative heat exchanges between the human body and the environment and surrounding surfaces. 3D-CFD software was used (Computational Fluid Dynamics), enhanced with a radiation module, both developed by the authors
The radiation module accounts for the radiative heat transfer between the active surfaces, including those related to the occupants
