  2. 1. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

    Author : Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Energy Saving; Thermoeconomic Assessment; Energy Management Scenario; Micro Climate Control; Solar Building; Closed Greenhouse; SRA - Energy; SRA - Energi;

    Abstract : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. READ MORE

  4. 2. On a learning system for industrial automation : Model-based control and diagnostics for decision support

    Author : Moksadur Rahman; Konstantinos Kyprianidis; Anders Avelin; Gunnar Bengtsson; John Hedengren; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Learning system; Supervisory system; Pulp and paper; Micro gas turbine; Process modelling; Model-based control; Diagnostics; Decision support; Anomaly detection; Fault detection; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Access to energy is fundamental to economic and technological advancement. Hence, the more the world develops, the greater the demand for energy becomes. Evidently, the production and consumption of energy alone account for more than 80% of global anthropogenic greenhouse gas (GHG) emissions. READ MORE

  5. 3. Non-CO2 greenhouse gases, uncertainty and land-use competition

    Author : Daniel Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kyoto protocol; energy system; integrated assessment; environmental economics; land use change; bioenergy; climate change; greenhouse gases; GWP;

    Abstract : Over the past 250 years the concentrations of greenhouse gases in the atmosphere have increased drastically. It is close to scientific consensus that these changes have increased the temperature of the earth. READ MORE

  6. 4. 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

  7. 5. Energy efficiency improvements in logistics as a means to environmental sustainability: The case of capacity utilisation in road freight transportation

    Author : Jessica Wehner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Capacity utilisation; household logistics capability; system levels; distribution structure; logistics system; energy efficiency; last-mile fulfilment; overcapacity; system boundaries; road freight transportation;

    Abstract : The energy consumption in logistics, and especially in road freight transportation, is steadily increasing and with that the greenhouse gas emissions which have a negative impact on the environment. In order to improve environmental sustainability of logistics, a change in the actors’ behaviour and policies is needed since the development of technology alone is not sufficient. READ MORE
