  2. 21. Energy Efficiency in the Residential, Service and Energy Sectors : Barriers, Drivers and System Studies

    Author : Stefan Blomqvist; Louise Ödlund; Patrik Rohdin; Erik Dahlquist; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Efficiency; Barriers; Drivers; System Studies;

    Abstract : Increased energy efficiency is a prerequisite for achieving the national energy and climate goals, the goals set by the European Union, and the Sustainable Development Goals adopted by the United Nations. Close to 40% of Sweden’s total energy use and approximately 20% of domestic greenhouse gas emissions are allocated to the residential and service sector. READ MORE

    Abstract : The thesis focuses on the efficiency of the space heating system. In particular, the efficiency factors measure the efficiency of thermal zone. The efficiency factors measures how the energy is used in a space heating. READ MORE

  5. 23. Climatology and firn processes in the lower accumulation area of the Greenland ice sheet

    Author : Charalampos Charalampidis; Veijo Pohjola; Dirk van As; Rickard Pettersson; Douglas Benn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; Greenland ice sheet; accumulation area; automatic weather stations; surface energy balance; melt–albedo feedback; surface mass budget; snow; firn; meltwater; percolation; refreezing; runoff;

    Abstract : The Greenland ice sheet is the largest Northern Hemisphere store of fresh water, and it is responding rapidly to the warming climate. In situ observations document the changing ice sheet properties in the lower accumulation area, Southwest Greenland. READ MORE

  6. 24. 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

  7. 25. Prevalence of refractive errors and incidence of myopia in Swedish schoolchildren

    Author : Pelsin Demir; António Filipe Macedo; Karthikeyan Baskaran; Niall Strang; Linnéuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Refractive error; myopia; prevalence; incidence; risk factors; children; fovea; macula; autorefractor; aberrometer; synfel; refraktion; myopi; barn; prevalens; incidens; riskfaktorer; fovea; makula; autorefractor; aberrometer; Optometry; Optometri;

    Abstract : PurposeThe aim of this thesis was to investigate the prevalence, incidence, and risk factors for myopia development in a cohort of Swedish schoolchildren. The specific goals were: - to recruit a cohort of children aged 8 to 16 years and to follow the cohort over a period of 24 months with regular study visits; - to investigate the predictive value of relative peripheral error and other optical parameters for the prevalence and incidence of myopia; - to determine and investigate the predictive value of genetic and environmental factors, and structural characteristics of the eye to the incidence of myopia.
