Summary for decision-makers

Summer thermal comfort is a major issue for public health and carbon footprint reduction. Solar protection systems, far from being simple accessories, can substantially improve indoor comfort while reducing energy consumption. The CALEEPSO tool, developed by Actibaie, allows users to quantify the energy savings and CO₂ emissions avoided by installing solar protection systems on their windows. Based on dynamic thermal simulations, CALEEPSO uses advanced technologies to provide clear indications of the impact of these devices on thermal comfort, taking into account various climatic and design parameters.

With CALEEPSO, professionals can easily simulate the benefits of solar shading by defining its configuration, including geographic area, orientation, glazing type, and management method. The results, comparing scenarios with and without solar shading, allow decision-makers to take informed measures to improve summer comfort in buildings. In a context where climate challenges are increasingly present, integrating innovative solutions such as those put forward by CALEEPSO is becoming essential to guarantee a healthy and energy-efficient indoor environment.

Summer is coming, temperatures are rising... and with them, an increasingly central question: How can we keep our homes and buildings cool without blowing out the air conditioning?
The answer may lie in your shutters, blinds or sunshades!

Discover CALEEPSO, the tool that calculates your energy savings thanks to solar protection

Yes, these devices are much more than just a facade accessory. They can play a key role in improve thermal comfort, reduce energy consumption and even limit our carbon footprint.

But how do you know if sunscreen is really effective?

This is where comes in CALEEPSO, a smart and easy-to-use tool developed by the professional organization Actibaie.

This online simulator allows you to calculate in just a few clicks the energy and CO₂ savings you can make by installing solar protection on your windows.

Why is this important?

Because the summer comfort, it is not luxury. It is a public health issue, energy sobriety andadaptation to climate changeAnd to answer this, sunscreens are essential.

And no, we're not talking about sunscreen here, but rather concrete solutions to prevent our interiors from turning into a furnace at the slightest peak of heat.

Thanks to tools like CALEEPSO, we better understand the real impact of sunscreens and we act, with full knowledge of the facts.

Behind CALEEPSO, a real scientific base

No guessing or rule of thumb here: CALEEPSO is based on hundreds of dynamic thermal simulations, carried out using two reference software programs:

PLEIADES+Comfie for housing,
TRNSYS for school and office buildings.

These software programs simulate the thermal behavior of a building hour by hour, over a whole year, taking into account:

Sunshine depending on the orientation of the facade,
Local weather (8 French climate zones),
The type of glazing,
The current climate... but also that planned for 2040 according to IPCC scenarios.

What CALEEPSO allows you to visualize

Once your configuration is defined, the tool displays several clear and concrete indicators:

Energy savings (in kWh) produced thanks to solar protection,
Greenhouse gas emissions avoided,
Thermal comfort, with an indicator called degree-hours of discomfort (DH),
and maximum or average indoor temperature, depending on the type of building.

This data allows us to compare a scenario “with” and “without” sun protection — and the results often speak for themselves.

How does the simulation work?

Nothing could be simpler! The user chooses:

Sa geographical area,
The orientation of the facade,
Le type of glazing,
Le type of sunscreen (shutter, blind, BSO, etc.),
Le color of the product (yes, that also counts for thermal comfort!),
And finally, the management mode : manual, motorized or automatic (with sensors or home automation).

In a few seconds, you get two simulations:

One based on the average climate for the years 2009-2019,
Another one with a projected climate scenario for 2040.
