“…This problem was discussed in detail in [108]. To assess thermal performance of TABS different methods and indicators can be used [109,110]. But from the point of view of a building's owner, administrator or user the most important is energy consumption required to maintain certain level of indoor comfort.…”

Modern buildings with new heating, ventilation and air conditioning (HVAC) systems offer possibility to fit parameters of the indoor environment to the occupants’ requirements. The present paper describes the results of measurements performed in an office room in the first Polish passive commercial office building during four months of normal operation. They were used to calculate parameters describing thermal comfort: vertical air temperature profile, floor surface temperature, predicted mean vote (PMV) and predicted percent of dissatisfied (PPD). Obtained results confirmed good thermal conditions in the analysed room. The average temperature of the floor’s surface varied from 20.6 °C to 26.2 °C. The average vertical air temperature, calculated for working days, was from 22.5 °C to 23.1 °C. The temperature difference between the floor and 5 cm below the ceiling was from −0.9 °C to 6.3 °C. The PMV index varied from 0.52 to 1.50 indicating ‘slightly warm’ sensation, in spite of ‘neutral’ reported by employees. Also measured cooling and heating energy consumption was presented. The performed measurements confirmed the ability of thermally activated building system (TABS) to keep good thermal conditions.

“…They offer a low thermal mass as compared to concrete core slabs. However they have high cooling output and faster response time as compared to chilled concrete core slabs [5]. They are perfectly suited for buildings with varying cooling loads and can be easily integrated with ventilation supply from the ceiling [4].…”

- Energy supervision in buildings is essential which would manage the energy utilize as well as the cost concerned while maintaining comfort conditions and necessities in indoor environments. In recent years, radiant cooling has acquired a lot of popularity as it can be attributed to the fact that it offers potential to reduce cooling and heating energy consumption by lowering peak loads when coupled with building thermal mass. This can be further enhanced by the application of low energy ventilation systems. Displacement ventilation is one of the techniques to maintain adequate level of air purity and thermal comfort in indoor. The sustainable aspect of these radiant cooling systems to expand the control in Energy and Environmental system design recommendation for low carbon emission in the environment.

The article focuses on the description of an innovative solution and application of active thermal protection of buildings using thermal insulation panels with active regulation of heat transfer in the form of a contact insulation system. The thermal insulation panels are part of a prefabricated lightweight outer shell, which together with the low-temperature heating and high-temperature cooling system creates an indoor environment. The energy source is usually renewable energy sources or technological waste heat. Research and development of an innovative facade system with active thermal protection is in the phase of computer simulations and preparation of laboratory measurements of thermal insulation panels with various combinations of energy functions. In the article we present theoretical assumptions, calculation procedure and parametric study of three basic design solutions of combined energy wall systems in the function of low-temperature radiant heating and high-temperature radiant cooling.
