How to deal with the sun’s rays?<\/h2><\/div>

As part of the construction of a kindergarten and elementary school in Biol, we carried out a shading study<\/strong> for the east and west facades to propose an optimal solution for managing solar radiation.<\/strong> The main objective was to reduce solar gain as much as possible in summer<\/strong>, while maintaining a good level of natural lighting and warmth in winter.<\/p>\n<\/div>

ARCHWIZARD<\/strong> software was used and the reflection coefficient <\/strong>(emissivity) of the brise soleil blades used in this study is equal to 0.5.<\/div>\n

The study<\/h2><\/div>

We analyzed the solar reception of<\/strong> unprotected facades<\/strong> to understand the direct impact of radiation. The results show that both the east and west facades are exposed to direct sunlight. Given the large bay windows on these fa\u00e7ades, the installation of sunshades<\/strong> seems essential to limit excessive heat gain.<\/strong><\/p>\n<\/div><\/div><\/div>

Solar reception without sunshade<\/h3><\/div>

An analysis of the solar radiation received by facades without sunshades has enabled us to draw up an inventory of the situation. The maps below illustrate direct solar radiation reception by month and time of day for each fa\u00e7ade:<\/p>\n<\/div><\/div><\/div>

West facade<\/p>\n<\/div>

<\/span><\/div><\/div><\/div>

On the east facade, exposure to direct sunlight begins at sunrise and continues until mid-day. The west fa\u00e7ade then takes over, capturing the sun’s rays until the end of the day.<\/p>\n

Given the large surface area and number of windows, the addition of solar shading devices is necessary to limit excessive solar gain.<\/p>\n<\/div><\/div><\/div>

Solar reception with sunshade<\/h3><\/div>

After studying the configuration with TELLIER AZUR AS300x5<\/strong><\/a> type sunshades, installed vertically with the blades laid down.<\/strong><\/p>\n

The effectiveness of the sunshades was simulated according to the inclination of the blades and their positioning, adapted to the fa\u00e7ade.<\/p>\n
