Eaves is something that is common to see on buildings. But what is the purpose of the eaves and how do they affect the building? To get an answer to that and if you really need to build eaves is the main purpose of this work. The work is mostly done as a literature study in which existing literature concerning eaves is compiled. As a completion to that, interviews have been performed with people that has a lot of knowledge about eaves to see what they have to say about the effect eaves have on a building. In today’s building regulations it’s hard to tell when you should build with eaves and how long the eaves should be because they are formed as functional requirements. If you instead look at older building regulations, recommendations on how to build with eaves can be found. Many clients require eaves on their buildings, but they do not give any reasons to it. The common picture based on answers from interviews with people in the industry is that eaves protects the façade and mostly the upper parts. It is possible to build without eaves, but it should be considered a risk. Some materials are extra sensitive to wind driven rain and then it’s more important to build eaves. The research that has been done about eaves is mostly simulations, but field measurements have also been made. Both the simulations and measurements show that it is the upper parts of the facade that is exposed to the most wind driven rain and it is also the upper parts of the facade that is mostly protected by eaves. So even if the impact that the eaves have on a build is not too well determined it’s clear that the eaves have a function. The eaves do not only protect the building as an extra roof it also changes the wind flow around the building and gives good protection to the upper parts of the facade that is the most exposed part of the faced for wind driven rain for buildings without eaves.
