  2. 1. Supporting evidence-based design using lighting simulations : A framework for lighting simulation of visual comfort in building design

    Author : Anahita Davoodi; Myriam Aries; Peter Johansson; Thorbjörn Laike; John Mardaljevic; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lighting quality; visual comfort; lighting simulation; evidence-based design; field study; post-occupancy evaluation; Ljuskvalitet; visuell komfort; ljussimulering; evidensbaserad design; fältstudie; brukarutvärderingar;

    Abstract : This research aims to integrate lighting simulation into the evidence-based design process for achieving improved lighting outcomes in built environments with a particular emphasis on visual comfort analysis in office settings. The objectives of the study include 1) understanding the current usage of lighting simulation tools, learning designers’ experiences' and needs, 2) providing a conceptual framework to integrate the use of lighting simulation in the evidence-based design (EBD) process, 3) testing the usage of the conceptual framework (named EBD-SIM) through two field studies.

  4. 2. Lighting Control Systems for Energy Saving and User Acceptance: State-of-the-art and future directions

    Author : Niko Gentile; Institutionen för arkitektur och byggd miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Indoor lighting; lighting control system; lighting control; energy saving; energy efficiency; user acceptance; human factor; occupancy strategies; absence sensor; presence sensor; lighting switch; manual switch; daylight harvesting system; daylight-linked system; photoelectric dimming; photosensor.;

    Abstract : Lighting accounts for one-fifth of global electricity use. In Sweden, energy demand for lighting corresponds to 20% of the total electricity use in office buildings. Lighting retrofit measures are considered to be among the most cost-efficient way to reduce energy use in buildings. READ MORE

  5. 3. Lighting simulation for a more value-driven building design process

    Author : Anahita Davoodi; Thorbjörn Laike; Peter Johansson; Annika Moscati; Jönköping University; []
    Keywords : lighting simulation; lighting design; lighting quality; energy efficiency; perception;

    Abstract : Concerns about global warming are increasing, hence, the urgency to cut carbon emissions. Reducing energy consumption, including lighting energy, is seen as the primary solution. Yet, solving the environmental factor should not come at the cost of other pillars of sustainable development. READ MORE

  6. 4. Lighting Control Systems to Save Energy in the non-Residential Sector : State-of-the-art, Field Studies, and Simulations

    Author : Niko Gentile; Institutionen för arkitektur och byggd miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Indoor lighting; lighting control system; lighting control; energy sav; energy eff; user acceptan; degree of acceptance; human factor; occupancy strategy; presence strategy; absence strategy; daylight harvesting; daylight-linked; daylight; photoelectric dimming; photosensor; manual switch; functional illumination; standby;

    Abstract : 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.

  7. 5. Urban outdoor lighting : Pedestrian perception, evaluation and behaviour in the lit environment

    Author : Johan Rahm; Institutionen för arkitektur och byggd miljö; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Outdoor lighting; Street lighting; Pedestrian; Walking; Walkability; Perceived safety; Urban design; Perception; Environmental psychology; Elderly; Mobility;

    Abstract : Walking plays an essential role in sustainable transport systems, as nearly all journeys in the urban environment incorporate walking in one way or another. In parts of the world, for long periods of the year, seasonal variation in daylight hours means that pedestrians must rely on outdoor lighting to make cities accessible after dark. READ MORE
