The window and the building envelope have gone from being a mere construction element to becoming key pieces in energy efficiency.. Within the framework of Almost Zero Consumption Buildings (ECCN) and rehabilitation, Solutions that not only provide comfort are becoming more and more relevant., but also reduce consumption and emissions. Idemo Motors offers products designed to respond to these demands, where sustainability and automation are protagonists.
Solar engines: wiring-free efficiency
Idemo solar motors iON y S-TECH eliminate the need for wiring thanks to batteries recharged by a solar panel, which simplifies installation in rehabilitation and reduces the energy footprint at ECCN. Studies on automated sun protection systems show significant energy savings: A field study with automated curtains/blinds in an urban skyscraper observed total consumption reductions on the order of 25% in real conditions, highlighting the potential of automated systems to reduce overall building energy demand.

Besides, the solar panel power locates the energy in the element of the envelope itself, avoiding losses in electrical distribution and facilitating solutions with integrated renewable energy, very aligned with the ECCN and energy rehabilitation objectives.
Idehome Neo: home automation at the service of efficiency
If the solar motor solves the energy and installation issue, the system Idehome Neo goes one step further by connecting the building envelope with home automation. This solution allows automate blinds, windows and sun protection systems with smart functions based on the natural rhythm of the day.
For example, The user can program the automatic lowering of blinds when the sun sets, promoting thermal comfort and reducing the need for artificial air conditioning. In the same way, the rise with sunrise makes the most of natural light, reducing electrical consumption in lighting. This automation turns the window into an active actor in the energy management of the building.
Data on energy savings and emissions reduction
Providing the building envelope with automated solar protection solutions guarantees improvements in energy efficiency that allow compliance with the requirements of ECCN construction:
- Estimated total savings: Field studies with motorized interior blinds/insulators have measured reductions in total building consumption of around 20–25% in real conditions when shading and insulation strategies are optimized. This includes savings on lighting, refrigeration and, to a lesser extent, heating.
- Lighting and daytime control: Lawrence Berkeley National Laboratory research shows lighting savings in controlled areas of up to 30% thanks to dimming controls combined with shading management, with additional effect on cooling load reduction.
- HVAC (cooling) and exterior shading: Home-laboratory tests have shown HVAC savings of up to ≈10% by incorporating exterior shading solutions versus traditional interior covers, especially on summer days or in moderate to severe summer climates.
- Winter loss reduction: Efficient covers/blinds can reduce heat loss through windows (p. ej. Well-fitting cellular shades reduce loss by up to 40% in the window element), which translates into significant heating savings in the cold season—approximately ~10% of the heating demand in typical homes—according to technical energy efficiency guides.
These percentages vary depending on climate, orientation, glazing type, and control strategy (manual vs. automated). Nevertheless, The scientific and technical evidence is consistent that Automation and integration with climate sensors increase the effectiveness of the solution.
Climate sensors: intelligent reaction to environment
All products of Idemo can be connected to rain sensors, wind and solar radiation. This intelligence reduces risks (automatic protection against wind or rain), increases the useful life of exterior elements and optimizes the energy performance of the building by acting in real time based on exterior conditions, which favors both the reduction of consumption and the reduction of emissions associated with air conditioning and electricity generation.
Tailored solutions for a sector in transformation
Faced with the regulatory requirements of the ECCN and the energy rehabilitation policy, Idemo's proposal—solar motors iON y S-TECH, Idehome Neo and sensor compatibility—offers a low consumption combination, renewable energy and easy installation. Figures collected by research and reference laboratories show that integrating automated shading and home automation control is not just about comfort, but a profitable and effective measure to reduce consumption and emissions in both new and rehabilitation projects.
