What information should be provided when requesting a solar shading quotation?

Learn what information helps produce an accurate solar shading quotation, including building orientation, glazing specification, solar gain targets, façade design, maintenance requirements, and project programme.

The more information available at enquiry stage, the more accurate and meaningful a solar shading quotation is likely to be. While budget guidance can often be provided from concept-level information, understanding the project’s performance requirements, architectural intent, and design constraints allows a specialist contractor to recommend the most appropriate solution and identify opportunities for optimisation at an early stage.

One of the most important pieces of information is the objective of the solar shading system. In some projects, the primary driver may be reducing solar gain and cooling loads. In others, the focus may be glare reduction, occupant comfort, planning requirements, façade aesthetics, or a combination of these factors. Understanding the desired outcome helps ensure the proposed solution is tailored to the project’s specific requirements.

The most effective solar shading quotations are often based on performance objectives rather than a preconceived product solution. While it may be tempting to specify a particular blade size, spacing, or configuration from the outset, these decisions are often best informed by factors such as orientation, glazing specification, solar exposure, and the building’s intended use. Defining the required outcome rather than prescribing the solution too early can create greater flexibility and often leads to a more effective overall design.

Project drawings are particularly important when assessing solar shading requirements. Elevations, façade sections, general arrangement drawings, glazing schedules, and planning information help establish the building geometry, façade composition, fixing constraints, and the visual objectives of the project. Even early-stage concept information can provide valuable context.

Where available, the following information can significantly improve the quality and accuracy of a solar shading proposal:

• Building orientation
• Glazing specification
• Solar gain reduction targets
• Daylighting requirements
• Occupant comfort objectives
• Planning requirements
• Preferred blade profiles or shading strategies
• Material and finish preferences
• Maintenance and access requirements

The glazing specification is particularly important. Solar shading systems and glazing performance should ideally be considered together, as both contribute to the overall thermal and visual performance of the façade. Early coordination can often identify opportunities to optimise the relationship between the solar shading strategy, glazing specification, daylighting performance, and building services design.

Structural and façade interface information should also be provided wherever possible. The substrate type, fixing zones, movement joints, support requirements, and façade build-up can all influence the design and installation methodology of the solar shading system. Early identification of these constraints helps minimise redesign and improves programme certainty.

Maintenance and lifecycle considerations should not be overlooked. Access for cleaning, inspection, maintenance, and potential future replacement should be considered alongside the aesthetic and performance objectives of the system. This is particularly important on high-rise buildings or projects incorporating specialist access equipment such as building maintenance units (BMUs).

As with any specialist façade system, consistency across the enquiry information is essential. Drawings, specifications, schedules, and performance requirements should align wherever possible to ensure all parties are pricing the same scope and working towards the same project objectives. A coordinated enquiry package allows more meaningful comparisons between quotations and reduces the risk of assumptions, omissions, or scope gaps emerging later in the project.

Programme information is also valuable. Understanding key design, procurement, manufacturing, and installation milestones allows realistic lead times and project constraints to be considered from the outset.

Importantly, not every aspect of the design needs to be fully resolved before making an enquiry. Early engagement with a solar shading specialist can often help identify opportunities for value engineering, improve coordination with the wider façade design, and ensure performance objectives are established before key design decisions become fixed.

At Solinear, we regularly support architects, façade consultants, contractors, and design teams from the earliest stages of project development. By understanding the architectural intent, environmental objectives, and technical requirements of a project, we can help develop solar shading solutions that balance aesthetics, performance, buildability, and long-term value.
