But a haul through history, reviewing its pages and analyzing it, inherently brings up old and new question, like: Is it possible to alter negatively the image of historic buildings and monuments through inadequate lighting to the degree of distorting the perception that people have of the work? and if so, what are the causes that generate it? Do the light designers take into consideration criteria to protect not only historic buildings and monuments, but also the environment? What are the consequences that may generate the inadequate lighting of urban heritage to the environment? What are the factors to consider for a proper illumination of urban heritage? The answers to these questions will help lay the foundation for proper illumination of the urban heritage, avoiding at the maximum the light pollution and the effects that it generates, seeking a balance and harmonious reconciliation between the technology, urban heritage and environment, taking as a framework and the case study the urban heritage of a city from the colonial era in southern Mexico, with pre-Hispanic roots and where today you can still see through its streets and buildings an atmosphere of mysticism reflection of their folklore and traditions, this city is known as Chiapa de Corzo, Chiapas.}, subject = {Konservierung}, language = {en} } @phdthesis{Laar2002, author = {Laar, Michael}, title = {Untersuchung zur Tageslichtnutzung in den feucht-heißen Tropen am Beispiel Rio de Janeiros}, doi = {10.25643/bauhaus-universitaet.47}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20040225-497}, school = {Bauhaus-Universit{\"a}t Weimar}, year = {2002}, abstract = {Bei der Untersuchung der Tageslichtnutzung in den Tropen werden zun{\"a}chst die geschichtliche Entwicklung der Architektur in Rio de Janeiro und ihre klimatische Anpassung, die Tageslichtsituation vor Ort und die Bedingungen f{\"u}r den visuellen Komfort an Bildschirmarbeitspl{\"a}tzen in B{\"u}rogeb{\"a}uden analysiert.

This is often achieved by experimental trials until reaching an acceptable result. Several rendering softwares (such as Radiance) allow an accurate computation of lighting for each point in a scene, but this is a long process and any modification requires the whole scene to be rendered again to get the result. The first guess is empirical, provided by experience of the operator and rarely submitted to scientific considerations. Our aim is to provide a tool for helping designers to achieve this work in the scope of global illumination. We consider the problem when some data are asked for : on one hand the mean lighting in some zones (for example on a desktop) and on the other hand some qualitative information about location of sources (spotlights on the ceiling, halogens on north wall,...). The system we are conceiving computes the number of light sources, their position and intensities, in order to obtain the lighting effects defined by the user. The algorithms that we use bind together radiosity computations with resolution of a system of constraints.}, subject = {Architektur}, language = {en} }
