Sunlighthouse is a VELUX Model Home 2020 residential building in Austria. The main objective of the Model Home 2020 initiative is to create environmentally-friendly low-energy buildings with a strong focus on the health and well-being of their occupants. A key factor for achieving this is to provide the interiors with generous levels of natural light. Daylight performance analyses were actively used during the design process of Sunlighthouse and following are the final results from the evaluation in Daylight Visualizer.

In the VELUX Group we are working on improving our simulation tools for the analysis of thermal comfort in homes. Soon VELUX Energy and Indoor Climate Visualizer will have functionalities permitting to visualize temperature levels, as well as the influence of direct sun and solar shading. False color animations of the calculation results can be generated and the effect of solar shading demonstrated. Results can be shown as operative temperature or mean radiant temperature in […]

A considerable body of research shows that people prefer daylit spaces to those lacking natural light. Why should this be? If there is sufficient light to see, why would people prefer one source to another? To answer this question, we need to understand the evolved relationship between humans and natural light.
Imagine you are on a camping trip that lasts a lifetime. You and your small band of hunter-gatherers wake up with the first light […]

Recent media reports have cautioned against the use of blue-rich white light sources at night such as iPhones, tablets, computers and bright LEDs lightbulbs at night. To better understand the concern and discover how any bright light at night impacts your health you must first comprehend how the brain and body use ambient light to derive important signals which ensure not only our health but our very survival.
Light is more than […]

Over time we have progressively removed ourselves from and denied our dependencies upon the natural world, and moved out of sync with its rhythms. Science, which facilitated this, is now proving that the consequences harm us as well as the biosphere. For our health, and the happiness that reinforces it, we need to reconnect and live in greater harmony with nature in all its richly sustaining aspects by bringing these into the city and its buildings in as […]
