Achieving a balanced indoor climate should be a key objective for any project – creating a building which actively boosts the flow of natural light, improves ventilation, reduces harmful emissions and keeps noise pollution to a minimum.


Indoor climate is complex issue which demands both technical and design-led solutions. These solutions can challenge the original architectural vision, but are essential if a project is to meet both performance and aesthetic demands.

The ideal indoor climate - a contradiction in terms?

The basic requirements of a good indoor climate are governed by building regulations and workplace legislation, but these requirements can be contradictory. For example:

Balancing daylight and solar gain
With so much of our time spent indoors, it’s essential to maintain a good flow of natural light across a building – but if window size and position are not carefully planned, excess daylight can lead to overheating during summer.

Balancing insulation and ventilation
Airtight buildings use less energy by eliminating draughts and improving the efficiency of artificial heating – but can also compromise the flow of fresh air by reducing sources of ventilation.

Balancing ventilation and acoustic control
Acoustic control must be balanced with ventilation. If higher levels of acoustic control are required then this should be part of early stage building design so as not to compromise the overall ventilation strategy.

How to ensure a window specification delivers the ideal indoor climate?

A modern building makes multiple demands of every window unit installed. By consulting with our experts as early as possible, we can ensure the windows specified for your project deliver the optimum indoor climate. We help architects answer a range of relevant questions including:

  • How to improve performance, such as acoustics, solar control, and thermal, through window design and glass choice.

  • Whether solar control glazing should be considered, and the type of glazing required to meet the project g-value.

  • How to deliver a good indoor climate without compromising façade design or aesthetic vision.
