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.
An energy audit calculation procedure has been developed for existing buildings. It allows to estimate which measures have to be taken to improve the thermal performance of building envelope. An example of the application of this calculation procedure is presented.
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
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
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
Indoor aerosol particulate matter (PM) concentrations were measured gravimetrically in 36 carpeted bedrooms of asthmatic children. Particulate concentration was higher indoors than outdoors. High efficiency particule arresting (HEPA) filtration was shown dividing concentrations by about 2.
The filtration efficiency of residential furnaces air filters was measured in several houses in Canada. Even efficient filters have a minor influence on particulate levels in houses. The ways to reduce these levels were investigated. Results show for example how HEPA filters on supply air reduce indoor particle concentration.
Two aluminium windows were tested to determine the fractional penetration of airborne particles. Results show that mainly particles of 0.2 to 3 microns enter through both windows.
