1. Lighting Control Systems to Save Energy in the non-Residential Sector : State-of-the-art, Field Studies, and Simulations
Sammanfattning : This thesis examines the energy-saving potential for lighting when using traditional indoor LCSs in non-residential buildings. In the study, an overarching theoretical framework is used that distinguishes between energy efficiency and energy saving, as well as between energy use for lighting and functional illumination.

2. Daylight compliance of multi-dwelling apartment blocks : Design considerations, evaluation criteria and occupant responses
Sammanfattning : This thesis examines the daylight compliance of residential spaces, in particular apartments in multi-dwelling building blocks, and provides knowledge that may prove useful for the development of future daylight criteria for dwellings. The implications of design choices on daylight compliance of spaces and the effect of daylight criteria on the level of compliance are at the core of this work. LÄS MER
3. Energy Savings by Using Daylight for Basic Urban Shapes : With a Case Study of Three Different Street Types
Sammanfattning : During winter the sun is in short supply. But research at KTH shows that solar radiation can be facilitated while energy consumption for lighting is reduced. This provided that the buildings are appropriately designed. But, unfortunately, the sunlight is often not taken into account and the results are the opposite. LÄS MER
4. Daylight Influence on Colour Design : Empirical Study on Perceived Colour and Colour Experience Indoors
Sammanfattning : It is known that one and the same interior colouring will appear different in rooms with windows facing north or facing south, but it is not known how natural daylight from these two compass points affects perceived colour and the ways in which colour is experienced. The objective is to describe the perceived colours to be expected in rooms with sunlight and diffused light, and thus develop a tool for colour design. LÄS MER
5. Cooling Demand and Daylight in Commercial Buildings The Influence of Window Design
Sammanfattning : The modern design of office buildings shows a tendency to increase the window share per facade to be more impressive with grand visibility and well daylit rooms. An increased window share results in general in increased use of energy and costs for cooling, but these disadvantages can be reduced considering a more careful design. LÄS MER
