- Application of an indoor greenhouse in the energy and thermal comfort performance in a kindergarten school building in the South of Portugal in winter conditionsPublication . Conceição, E. Z. E.; Lucio, M. M. J. R.; Lopes, M. C.In this work a numerical model, which simulates the buildings thermal response and evaluates the indoor environment comfort, in transient conditions, is used in the application of an indoor greenhouse in the energy and thermal comfort performance in a kindergarten school building, in the South of Portugal, in Winter conditions. In the numerical simulation of the kindergarten school building, the 25 compartments, the 498 building main bodies and the 42 windows glasses, as well as two schools and three residential surrounding main buildings, are considered. This numerical model is applied in the evaluation of the kindergarten thermal behavior, using the indoor temperature field, and the occupants thermal comfort levels, using the PMV and PPD indexes. After to be compared the numerical and experimental indoor air temperatures field and identified the indoor thermal uncomfortable spaces, the numerical model is used in the evaluation of the indoor greenhouse performance, in order to increase the indoor air temperature and thermal comfort levels, using solar renewable energy, without increase of the kindergarten energy consumption. It is analyzed in detail the greenhouse ventilation operating time and the warm airflow transport way, using an internal ducts system or a corridor space, from the greenhouse to the indoor coldest spaces.
- Energy and thermal comfort evaluation for different passive solutions in a kindergarten in summer conditionsPublication . Conceição, E. Z. E.; Lopes, M. C.; Lucio, M. M. J. R.In this work a numerical model, which simulates the buildings thermal response with complex topology and evaluates the indoor environment comfort, in transient conditions, is used in the energy and thermal comfort evaluation for different passive solutions in a kindergarten, in Summer conditions. After the validation phase, this numerical model is applied in the evaluation of the building thermal behaviour, using the indoor temperature field, and the occupants' thermal comfort levels, using the PMV and PPD indexes. The introduction of a roof placed in the top of the kindergarten, horizontal shading devices placed above the windows level facing South and external pyramidal opaque trees placed in front to the windows facing West and East, used to reduce the indoor temperature level and to increase the indoor thermal comfort level, in Summer conditions, are analyzed.
- Energy and thermal comfort management in a kindergarten school building in the South of Portugal in Winter conditionsPublication . Conceição, E. Z. E.; Lopes, M. C.; Lúcio, Maria Manuela Jacinto do RosárioIn this work a numerical model, which simulates the buildings thermal response and evaluates the indoor environment comfort, in transient conditions, is used in the energy and thermal comfort management in a kindergarten school building in the South of Portugal in Winter conditions. After it's validation, this numerical model is applied in the evaluation of the building thermal behavior, using the indoor temperature field, and the occupants thermal comfort levels, using the PMV and PPD indexes. In the numerical model validation, experimental data and numerical values, for the indoor air temperature, are compared. In the experimental tests, for a typical Winter day, the outdoor and indoor environmental variables are measured. In the numerical simulation of the kindergarten school building, the 25 compartments, the 498 building main bodies and the 42 windows glasses, as well as all surrounding main buildings, are considered. The viability to build an indoor greenhouse, used to heat the cooled spaces, and the evolution of indoor thermal comfort level are analyzed.
