Planning a sun shading system: the most important facts in brief

  • A sun shading system increases comfort, energy efficiency and property value.

  • Planning should take place at an early stage - ideally during the design phase.

  • External systems such as Roller Shutters, External Venetian Blinds or Textile Screens are particularly effective.

  • Regular maintenance and care significantly extend the service life of sun shading systems.

Why a sun shading system is important

Sun shading systems not only provide shade. They regulate light and visibility, protect against overheating in summer, improve energy efficiency and contribute to the quality of living. Professional systems direct daylight in a targeted manner, preserve privacy and create a pleasant indoor climate - at any time of year.

Planning the sun shading system in the new building: early integration

When building a new building, the sun shading system should already be considered in the design phase. This allows installation variants to be seamlessly integrated into the building envelope - for optimum function and aesthetic uniformity.


What you should pay attention to

  • Window sizes and orientation

  • Solar radiation depending on the direction of the sky

  • Façade design and architectural concept

  • Electrical preparation for control systems

  • Automation options such as sun and weather sensors

For seamless integration of the sun shading system as early as the design phase, ROMA Architectural Consulting offers professional support. Here, planners and architects receive technical expertise, individual solution proposals and project-specific tendering aids - for perfect coordination of function and design.

Retrofitting during renovation: flexible and efficient

A sun shading system can also be effectively retrofitted to existing buildings. Front-mounted systems and solar drives for Roller Shutters in particular are ideal for energy-efficient window refurbishment, as they can be fitted without the need for complex electrical installations.


Advantages of retrofitting solar shading systems

  • No intervention in the façade with solar-powered systems

  • Promotes thermal insulation in summer and reduces cooling costs

  • Can be integrated into existing Smart Home systems

  • Possible funding via BAFA or KfW

Frequently asked questions (FAQ) about planning a sun shading system

What is the best way to plan a sun shading system in a new building?

In new buildings, the sun shading system should already be taken into account during the design phase. In this way, add-on systems, control technology and architectural requirements can be optimally integrated. ROMA Architectural Consulting supports planners with technical expertise and project-specific recommendations.

Can a sun shading system also be retrofitted?

Yes, many systems - especially front-mounted systems or systems with solar drives for Roller Shutters - are ideal for retrofitting. They do not require complex electrical installations and can often be installed without interfering with the fabric of the building.

Which sun shading systems are particularly effective?

External systems such as Roller Shutters, external Venetian blinds or vertical awnings offer the highest level of efficiency. They stop heat, glare and UV radiation even before they reach the window pane, thus increasing comfort and energy efficiency.

How long does a sun shading system last?

The service life of sun shading systems depends on material quality and regular maintenance. ROMA systems are designed for a particularly long service life. Cleaning, visual inspection and occasional specialist maintenance can further extend the service life.

How often should a sun shading system be serviced?

Maintenance by a specialist company is recommended approximately every one to two years - especially for motorized systems. Regular cleaning of the profiles, slats or Fabrics by the user also supports reliable operation.
