Evaluation of the acoustic performance of housing units is aimed at providing conditions for acoustic comfort inside them and at reducing impacts on the surrounding environment. This can be done either by on-site measurement of noise levels, when the building’s global acoustic performance is evaluated by computer simulation of noise Read more…
All commercial or industrial establishments must evaluate the impact caused by noise generated by their activities in their close surroundings. Similarly, air, road and rail traffic are also important noise sources whose impact on neighboring communities must be evaluated. These impacts can be studied by means of on-site measurements, evaluation Read more…
IPT evaluates the thermal performance of buildings without and with air conditioning. In the former case, IPT verifies if the interior surroundings conform to a set of requirements established to meet human needs for thermal comfort. The thermal performance of housing in Brazil is evaluated based on the ABNT NBR Read more…
The evaluation of lighting performance in buildings must take into account both natural and artificial light. In both cases, requirements of human visual comfort must be observed, which include factors such as suitable illumination for the activity undertaken and a dazzle-free visual field. Optimization of the use of natural light Read more…
Evaluations of thermal comfort in work environments can be of three kinds: heat overload, when health risks to workers exposed to intense heat are evaluated; cold overload, when health risks to workers exposed to very low temperatures are evaluated, and thermal comfort when environments without thermal overload but with possible Read more…
Materials for thermal insulation are characterized basically by two kinds of effect: resistive and radiant. Resistive insulation occurs by the material’s heat-transfer resistance. Because air is highly resistant to heat conduction, the best resistive insulation materials are those that confine air in small cells designed to eliminate convection movements. Insulation Read more…
Knowledge of the thermal and luminous properties of transparent or translucent materials such as glass and polycarbonates is important for solving problems related to comfort in built environments. The most important information is the percentage of solar radiation or light passing through a given component, such as a glass windowpane Read more…
Wind tunnel testing is a reliable tool to determine the effect of wind loads on engineered structures such as buildings, bridges, tunnels, towers, roofs, cables, chimneys, trestlework, vehicles and others. This application is directly related to situations which require highly accurate and reliable information or cases in which knowledge about Read more…
Just as packaging is important for the preservation of its contents, the types of cargo unitization and wrapping are important to maintain the integrity of the packaging. Safety in cargo handling operations, ever more mechanized, requires better control of components for handling and unitizing materials and also their fastening systems, Read more…
IPT analyzes and tests constructive systems and traditional or innovative products to evaluate their potential performance or expected behavior in use. This work involves several of the Institute’s laboratories and the results are published in IPT’s Technical Evaluation Reports or Technical Evaluation Documents which are supplied to clients. IPT also Read more…
