There are some important things to consider before selecting a skylight or light tube. Access to more sunlight can have profound effects on the efficiency of your home’s building envelope or skin. It’s always best to assess your house from a whole-building design approach. In new constructions we have the liberty to consider daylighting from the initial design stages. Skylights can be an integrated part of the design of a house allowing the interior to feel as though it’s connected with the exterior. The proportion of glass compared to the rest of the house can be calculated to reach certain energy-efficiency goals.
Another important ceiling-based light source is the pendant or chandelier. The line between these two can be blurry as a chandelier is essentially just a large (and often more decorative) pendant light. Chandeliers also are more likely to have multiple bulbs (which help create more layers) but what is or is not a pendant is still a gray area especially with more modern fixtures like the one here.
In a renovation on the other hand we have to consider what effect a new skylight will have on the efficiency of the existing building. In some cases the additional sunlight (and therefore heat) can help reduce the amount of energy needed to heat the house. It depends greatly on the local climate but also on the design of the building envelope of the house.
