  2. 6. Chlorophyll fluorescence as a biological feedback signal -for optimized plant growth conditions and stress diagnosis

    Author : Linnéa Ahlman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cucumber; indoor farming; abiotic stress; Fluorescence gain; ESC; biotic stress; basil; dynamics; strawberries; light spectrum; greenhouse lighting control; lettuce; powdery mildew Podosphaera aphanis; Pythium ultimum; LED; classification; lemon balm;

    Abstract : The use of light emitting diodes (LEDs) instead of traditional high pressure sodium lamps, in greenhouses and indoor growing facilities, enables tuning and optimization of both light intensity and light spectrum. This opens for an energy saving potential not possible otherwise. READ MORE

  4. 7. Equilibrium User Centred Lighting Design Towards the development of a lighting design that is individually psychologically, physiologically and visually supportive

    Author : Monica Säter; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Psychological; physiological and visual support.; User centred lighting design;

    Abstract : Why and in what way should daylight and artificial light be designed for the indoor environment in order to fulfil goals about visual comfort and light-related health? When the outdoor and indoor interactions of man, light, colour and space (MLCS) are compared to one other, the spectral component plays the decisive role (Hollwich 1979, p. 90). READ MORE

  5. 8. Power Estimation for Indoor Light Energy Harvesting

    Author : Xinyu Ma; Bengt Oelmann; Sebastian Bader; Alex Weddell; Mittuniversitetet; []
    Keywords : ;

    Abstract : The growing popularity of indoor light energy harvesting for wireless sensor systems and low-power electronics has created a demand for systematic power estimation methods for different lighting conditions. Although existing research has recognized the critical role played by the spectral information on the output power of a photovoltaic cell, power estimation methods have rarely considered it.

  6. 9. Energy efficiency in shopping malls. Energy use and indoor climate

    Author : Sofia Stensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy use; loads; cooling; Shopping mall; simulation; heating; field measurements;

    Abstract : The purpose of this licentiate thesis is to describe energy use, heating and cooling demands and the relative importance of internal heat loads in shopping malls. It will be a foundation for a future doctorial thesis in which alternative energy efficient HVAC systems for shopping malls will be analysed. READ MORE

  7. 10. Energy use in hotels and low-energy schools : Measurements and analysis of energy use and user-related parameters

    Author : Branko Simanic; Avdelningen för Installations- och klimatiseringslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hotel buildings; low-energy schoo buildings; measured energy use; measured user-related parameters; long-term measurements; koldioxid concentration; indoor air temperature;

    Abstract : Decreasing CO2 emissions in the building sector by improving energy efficiency isan essential part of the goal to reduce global CO2 emissions, as the sector accountedfor nearly 40 percent of the energy-related CO2 emissions in 2017.There are six main parameters that affect a building's energy use.
