The project is aimed at providing tools and validated data on building shading devices and control to the building profession and final users.
New algorithms describing the behaviour of the shading devices in respect to solar radiation, visible radiation and ventilation will be developed, validated and integrated in existing simulation tools. New 'smart' solar control systems for integration into the building envelope will be developed, with special emphasis on their impact on energy consumption and improvement of the indoor comfort.
Finally, design guidelines and a shading component Handbook will be produced for European architects and building designers.
The optical characterisation of the selected shading devices (external, interpane and internal, homogeneous and non homogeneous) will be carried out, by means of an outdoor integrating device mounted on a 2-axis tracking bench and by spectrophotometer techniques.
For the thermal characterisation, different techniques based on calibrated hot-box apparatus, solar caloriplate, test cell experiments and validated models will be applied and compared. Daylighting experiments aimed at the determination of daylighting factors and internal luminance distribution will be performed inside a full scale mock up office and in Test cells.
The impact of the shading devices on the ventilation of building spaces will be tested on the Test cells by measuring the air change per hour ( Tracer Gas Techniques ) and the wind velocity field before and after the shading ( Hot wire sensors ).
The smart solar control system will be identified by modelling, building simulation tools and control simulator subroutines.
The implemented solar control assembly will be tested inside Test cells in different climates. Simulation tools upgraded with specific shading algorithms will be used to perform sensitivity analysis on special case studies with the evaluation of saving and comfort impact.
Expected Achievements and Exploitation
The outputs of this project will be:
Proposal of prenormative testing standards for shading
Upgrade of the existing simulation models by integration of
new validated algorithms;
Design and implementation of a smart solar control assembly; Design Guidelines and Shading Component Handbook.
The results will be disseminated by publications and direct
contacts with manufacturers and practitioners already active in low energy buildings; workshops and conferences as well as
educational activities will be organized.
