3 impacts of low winter sun

There are lots of things to look forward to during the winter season. Christmas, New Year and speciality coffees to name a few, but one thing that is not welcomed in winter is low winter sun.

Low winter sun can play havoc with commercial buildings in all sectors. Whether it’s in education, retail, historic buildings or offices, here’s how low winter sun can impact these environments:


Glare from low winter sun can be incredibly frustrating especially as windows now make up a large proportion of modern buildings. Glare can cause uncomfortable working environments and can lead to lost productivity across all sectors. In buildings such as offices and schools where computer screens are vital to both work and learning, glare can be a real issue as it reflects off the screens. If nothing is done about it, it can cause eye problems for those exposed and other health issues such as headaches.

Display Screen Regulations are in place for visual comfort against glare for this very reason, and low winter sun can mean employers are not always complying with these.

Additionally, in places such as museums and art galleries, glare can reduce visibility for visitors detracting from their experience.

2. UV fading

UV fading is less of an immediate concern than glare as its impact is not instantly noticed. However, UV fading can be a serious long-term problem. Over time, fading can be dramatic and can cause damage to expensive property. Solar energy accounts for 90% of fading mainly in 3 wavebands: ultraviolet radiation, visible light and infra-red radiation (heat).

Fading can be most detrimental to shops, museums and historic buildings and isn’t usually covered by insurance policies so it can be expensive to replace damaged items.

3. Heat gain

Low winter sun can cause environments to become hot and uncomfortable. As the temperature rises, work productivity decreases. And in fact, the temperature can rise to a level that means employers are not complying with European Workplace, Health, Safety and Welfare legislation for thermal comfort.
