Our collective memory reminds us that summer holidays were intended to allow children to help their parents with the harvest.<\/h4>\n

This was still the case at the beginning of the 20th century: under the Front Populaire government in 1938, summer holidays were set to run from 15 July to 30 September.<\/h4>\n

Since then, society has changed. With the decline of the French peasantry, holidays since the 1980s have been concentrated in July and August, the hottest months of the year.<\/h4>\n

However, with hot spells sometimes starting in May and ending in September, educational establishments are increasingly faced with thermal discomfort that is damaging learning conditions.<\/h4>\n

Poorly adapted existing buildings<\/h3>\n

It wasn’t until the year 2000, and the thermal regulations of the same name (RT 2000), that summer comfort was finally taken into account in new construction. In fact, the buildings constructed from the post-war period until the new century were not designed to cope with this simple fact: it’s harder to learn when it’s hot. Large windows, poor insulation, little solar protection, rarely optimised orientation… the cocktail of discomfort is made up for the buildings of the half-century that followed the 2nd World War. So what solutions are possible to improve the situation in existing buildings?<\/p>\n

Ceiling fans to limit discomfort?<\/h3>\n

When carrying out comprehensive energy renovations, which generally focus on winter comfort, many schools and higher education establishments take the opportunity to improve summer comfort, in particular by installing high-performance brise-soleil or selective glazing.<\/p>\n

Unfortunately, work on the building rarely affects the surrounding environment: courtyards are generally paved with concrete, and classrooms are located in the heart of heat islands. The planting of vegetation, an obvious factor in improving summer temperatures, is unfortunately making very slow progress.<\/p>\n

Active solutions, such as air conditioning, are generally outlawed.<\/p>\n

Under these conditions, ceiling fans, which have already proved their worth in cr\u00e8ches, schools, colleges and universities in the French Overseas Departments and Territories, would appear to be an operational tool.<\/p>\n

The main advantage is well known: air speed brings an immediate gain in thermal comfort. A great deal of work has been carried out over the years to evaluate this precisely.<\/p>\n

We regularly use the table below from the Woods Ventilation Guide, which has the merit of simplicity.[\/et_pb_text][et_pb_image src=”https:\/\/www.exhale-fans.com\/wp-content\/uploads\/2023\/12\/GB-diagramme-guide-ventilation-wood-01.jpg” title_text=”diagramme-guide-ventilation-wood-01″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text ul_item_indent=”40px” admin_label=”Texte – Ilet du Centre : innovation \u00e0 tous les \u00e9tages” _builder_version=”4.16″ text_font=”Montserrat||||||||” ul_font=”||||||||” header_font=”||||||||” header_2_font=”Montserrat|700||on|||||” header_2_text_color=”#235ba8″ header_2_font_size=”24px” header_2_line_height=”1.2em” header_3_font=”Montserrat|500|||||||” header_3_text_color=”#0facee” header_3_font_size=”20px” header_3_line_height=”1.1em” header_4_font=”Montserrat|500|||||||” header_4_line_height=”1.1em” text_orientation=”justified” custom_margin=”||20px||false|false” z_index_tablet=”500″ global_colors_info=”{}”]<\/p>\n

That said, work on summer thermal comfort, presented in the ICEB Guide to Passive Summer Comfort<\/a>, has progressed over the years, and the ASHRAE 55 (USA) and EN 16-798 (Europe) standards now make it possible to assess in some detail the beneficial impact of air speed on the occupants of the premises concerned. The tool developed by the Center for the Built Environment at the University of California at Berkeley is particularly well thought out. It can be accessed here<\/a>[i]<\/a>.<\/p>\n

Is Toulon an example to follow?<\/h3>\n

In the Var department, Toulon town council has opted to set up a test campaign using ceiling fans in some of its schools, as reported by France Info in its article of 13 August 2022.<\/a>. The local authority has also adopted a broad and relevant approach to combating heatwaves, incorporating a range of highly operational solutions to complement the use of ventilation fans:<\/p>\n
