Improving Build Performance
“Gurtekin, Hartkopf and Loftness of Carnegie Mellon University reported average energy savings of 52% through the use of high-performance daylighting systems.“ (Carnegie Mellon University - 2004)
Save Energy
SOMFY CAN!
Solution: The sensors and automatic devices used in Somfy solutions reduce energy consumption:
> By prioritizing the use of natural light.
> By reducing solar gains in summer.
> By adapting building openings to occupancy periods (variable lesson times, holidays, etc.).
Benefit: Today, thanks to Dynamic InsulationTM we can create energy savings without compromising occupants’ comfort.
Maximize Return On Investment
SOMFY CAN!
Solution: Somfy centralized automation solutions are easy to integrate and operate and help decrease operating costs:
> By reducing energy consumption. > By reducing the number of manual
interventions required.
> By improving security and reducing damage and vandalism.
Benefit: The investments made in the construction of educational buildings are often significant. These facilities must therefore be designed and built in such a way as to extend their lifetime.
Expand Building Life Spans
SOMFY CAN!
Solution: Somfy solutions provide a bioclimatic design that will enhance the life span of a building by providing sustainabe solutions:
> Weather sensors automatically retract awnings in order to protect them from storms, reducing maintenance costs.
> The motors installed ensure gentle movements that extend the life of blinds.
> Centralization systems can be easily adapted to meet changes in regulations.
Benefit: The high-quality design and manufacturing of Somfy solutions mean that buildings fitted with these solutions ensure years of efficient service.
Energy savings with automated sun protection devices
According to simulation tool created by Lund University in Sweden, an investment of 1% to 2% of the total cost of the building results in energy savings of 20% to 40% (see table below).

Simulation definition: A 86,4m2 school room, with 18,52 m2 window glass (double glazing Low-E except for Abu Dhabi and Shanghai Double glazing, Façade wall U-Value: 0,33 W/m2K), representing 60% of the room façade section, south oriented. Sun protection device is an internal grey PVC. The comparison is made between sun protection device and no sun protection device, depending on light level considering 35 persons occupying the room, equipped with 864 W artificial lighting (detailed analysis available on demand).
