    Sammanfattning : To improve sustainability, social, environmental and economic aspects needs to be considered. The most optimal result appears when all three aspects are balanced equally, this is however often overseen by private investors, who focuses only on reaching economic sustainability at the expense of social and environmental sustainability.

  3. 2. Design, implementation and evaluation of a daylight estimation tool using 3D city model data

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Peter Nezval; [2021]
    Nyckelord :3D city model; CityJSON; solar energy; free and open-source software; 3D feature extraction; solar urban planning; sustainable urban development; geomatics; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Solar energy is an important component of sustainable urban development. However, it is still not reaching its full potential due to several reasons. One of them is a lack of free tools based on open geodata capable of estimating solar energy (daylight) metrics on building features, e.g. LÄS MER

  4. 3. CONSTRUCTION EQUIPMENT FUEL CONSUMPTION DURING IDLING : Characterization using multivariate data analysis at Volvo CE

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Mujtaba Hassani; [2020]
    Nyckelord :Idling condition; environmental effect; diesel fuel; machine learning; multivariate data analysis; partial least square regression; support vector machine regression; principal component analysis; principal component regression; correlation coefficient matrix; artificial neural network; exhaust emission reduction techniques; global warming; emission regulation; CO2 estimation techniques; Gaussian process regression;

    Sammanfattning : Human activities have increased the concentration of CO2 into the atmosphere, thus it has caused global warming. Construction equipment are semi-stationary machines and spend at least 30% of its life time during idling. The majority of the construction equipment is diesel powered and emits toxic emission into the environment. LÄS MER
