21. Sustainable lighting in offices "How to save energy in offices with a new lighting design ?" : An energy efficient Lighting design approach in offices
Magister-uppsats, KTH/LjusdesignSammanfattning : Sustainable efficient lighting has become as one of the most important issues in the office environment In Sweden, energy demand for lighting corresponds to 20% of the total electricity used in office buildings (1), while It has been estimated that lighting accounts for about 20% of the total power generation of the world (2). This thesis investigates how to make lighting in offices more sustainable and focuses on energy efficiency, to save energy through creating guidelines related to light source technologies, lighting control systems and the user preferences.

22. Sustainable lighting in offices : " How to save energy in officeswith a new lighting design ? "
Magister-uppsats, KTH/LjusdesignSammanfattning : Sustainableefficient lighting is becoming seen as one of the mostimportant issues in the office environment In Sweden, energydemandfor lighting corresponds to 20 of the total electricity use in officebuildings 31 while lighting form on average 33 1 of the electricityconsumption in UK office buildingsThisthesis investigate how to make lighting in offices more sustainableand focus on energy efficiency, to save energy through creating guidelinesrelated to light source technologies lighting control systems and the userbehavior then apply those guidelines to an existing office throughsuggesting a new lighting designTheexisting office in this case is the ÅF company 10 th office floor locatedin Stockholm SwedenThisinvestigation methodology consist of 2 main parts literature review andProject ( study At the first part, methods used are a combination ofliterature review related to saving energy through sustainability in lightingand how light source technology lighting control systems and the effect ofuser behavior could help to create more energy efficient lighting systemsAtthe second part, methods used in the Project study analyzed throughqualitative methods through surveys in addition to quantitative methodthrough and personal observations The used methods helped to createguidelines for the new suggested lighting design for ÅF 10 th office floorpartTheResults shows that the new suggested lighting design saved up to31 96 than the current lighting situation3 ..
