2. 1. Cooling Demand and Daylight in Commercial Buildings The Influence of Window Design

   Author : Hendrik Voll; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; daylight; building design; solar factor; glare.; energy need; window share; Commercial buildings; cooling demand;

   Abstract : 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. READ MORE

4. 2. 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.

5. 3. Energy Efficient Window Systems. Effects on Energy Use and Daylight in Buildings

   Author : Helena Bülow-Hübe; Avdelningen för Energi och byggnadsdesign; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; thermal transmittance; solar energy transmittance; shading device; solar protection; cooling; heating; energy demand; building; low-emittance coating; window; glazing; comfort; user aspects; operative temperature; Architecture; Building construction; Byggnadsteknik; daylight; perception; interior design; Arkitektur; inredningsarkitektur; Energy research; Energiforskning;

   Abstract : This thesis deals with energy-efficient windows in Swedish buildings. Parametric studies were performed in the dynamic energy simulation tool Derob-LTH in order to study the effects of window choices on energy use and indoor climate for both residential and office buildings.

6. 4. Single Skin Glazed Office Buildings - Energy Use and Indoor Climate Simulations

   Author : Harris Poirazis; Avdelningen för Energi och byggnadsdesign; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Modern office buildings have high energy savings potential and potential for indoor climate improvements. During the nineties many office buildings with glass facades were built, in several cases with double skin glass facades. READ MORE

7. 5. 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
