Two models were applied to predict particle deposition in ducts, one theoretical, the other based on experiments. These models are described and a comparison of their predictions is compared to experimental results.
Performance of solar systems used to preheat ventilation air was investigated through long-term (several years) measurements on three buildings in Czech Republic. Buildings and results are described.
Photovoltaic/thermal hybrid solar collectors (producing electricity and warm air) were simulated with TRNSYS software when used together with a heat pump and an auxiliary gas boiler in a complete system to produce space heating and domestic hot water.
This paper presents 3 full-scale test rooms in a series of 14 built in Italy, with different types of façades. The measurements of energy consumption and indoor environment allow a direct comparison between different solutions exposed to identiacal climat
The study has monitored two office buildings during 3 years changing position of dampers in order to control the air change in the buildings on periods of 3 months. CO2 levels, absenteism rate and rhinovirus in air samples are commented.
Numerical modeling and on site measurements were applied to the ventilated double-skin glazed façade of the Moravian Library building in Brno (Czech Republic) to determine the air temperatures and velocities into the façade. Calculations show that supply
CFD simulations and measurements were used in isothermal air-conditioned space of a gymnasium. Different airflow patterns due to different supply air were simulated. Results obtained are correct considering the complexity of boundary conditions.
The Moravian library's atrium in Brno (Czech Republic) is eight stories high. Ventilation is a combination of mechanical supply by nozzles in each gallery and a natural stack effect in the atrium from bottom to top. CFD has been used for design.
CFD calculations and laboratory measurements in a full-scale model were carried out to assess the performance of a full transparent second skin façade intended to equip an office building, composed of very low solar energy transmittance glass, and being v
Visual inspection is a subjective method but yet necessary to control duct cleanliness. In order to improve its reliability, a visual scale has been realised and results from a panel of 10 inspectors have been compared to measurements.
