Façade lighting of hotel buildings: Integration in the city and their impact on light pollution

The exterior lighting in hotel buildings has a significant impact on humans and the ambient environment of city centres. The case study is a small-sized Boutique hotel, located at the historic centre of Athens, as far as its façade lighting is concerned, in relation to the ambient environment and the lighting standards that the general area architecture has set. A special methodology is followed in order to estimate the consequences of the exterior lighting taking into account the relevant norms. The international databases and bibliography were studied also in order to identify best practices, regulations of similar cases and lighting systems that are used. Using existing regulations, lighting recommendations were identified and, in order to minimize light pollution, stricter restrictions were adopted. Finally, lighting calculations and visualizations were performed, using Relux software, in order to verify that the lighting methods and proposed equipment do not have an adverse impact in terms of light pollution.
