An article by Jan Denneman for [inst]ALLICHT

Indoor lighting is much weaker than natural daylight, confusing our biological clocks. This can lead to daytime sleepiness and poor sleep quality at night. The solution includes spending time outdoors in the morning, staying close to windows indoors, and using proper desk lighting.

In the article Jan explains the “3-30-300 rule”, emphasizing that the largest building cost lies in the people using it (€300), much larger than the investment costs ((€30) or energy costs (€3). By improving lighting to enhance well-being and productivity, significant savings can be achieved compared to the relatively small savings from energy costs.

In summary, the article underscores the importance of good lighting in buildings for human health, productivity, and financial benefits. Prioritizing proper lighting can lead to better sleep, increased energy, and substantial savings, countering the negative effects of indoor living.
