Daylight in classrooms is a critical factor in school design, in terms of its impact on students’ health, learning and visual performance. Providing adequate amount of evenly distributed daylight and glare prevention are important challenges in classroom design. Window configuration significantly affects the intensity and uniformity of daylight. This paper aims to investigate the effect o...

The major part of light weight timber constructions consists of insulation. Mineral wool is the most commonly used insulation due to its cost efficiency and easy handling. The fiber orientation and porosity of this insulation material enables flowthrough. The air flow resistance is low. If leakage occurs in the insulated bay section, the convective flow may cause energy losses and infiltration ...

A high-performance envelope is the prerequisite and foundation to a zero energy building. The thermal conductivity and volumetric heat capacity of a wall are two thermophysical properties that strongly influence the energy performance. Although many case studies have been performed, the results failed to give a big picture of the roles of these properties in the energy performance of an active ...

The transmission of the electric power to shore and concepts for the electrical system of offshore wind farms are evaluated with respect to selection of a cable. Necessity of use of a shunt by an AC cable connection to shore is addressed, Consequences of the use of a higher insulation of cables, use of three single core cables in triangular and linear configuration is compared in the paper.

At IEN, a guarded switching system for automatic selection of high value resistors under calibration was developed and metrologically characterized. By means of this system it is possible to select and connect to the measurement system [1, 2] high value resistors in three terminals configuration. As a matter of fact, its guard system allows to reduce the effects due to all the dispersion curren...
