  1. 1. Smart Energy Grids – Utilization of Space Heating Flexibility

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Johan Kensby; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; demand side management; heat pump; thermal energy storage; exhaust air heat pump; thermal storage in buildings; heat price control; smart; District heating; heat source shifting; demand response;

    Abstract : Buildings are the largest energy-using sector in the world. Since the generation of energy is highly associated with greenhouse gas emissions, contributing to climate change, there is a large focus on reducing energy use in buildings. READ MORE

  2. 2. The open absorption system : energy savings in different applications

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Lars Johansson; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : The open absorption system is a technique that makes it possible to recover energy in different processes using moist air. In most applications the latent heat in moist air is difficult to recover because of the low temperature. Processes using outdoor air to carry away moisture therefore have high energy demands.

  3. 3. Energy Efficiency in Residential Buildings in Mozambique - Measurements and Simulations

    University dissertation from Division of Building Science, Lund University

    Author : Gabriel Auziane; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy; Building; Measurements; Simulations; DEROB-LTH; Mozambique; Subtropical and Tropical climates; Energy efficiency; PV system; Electrical energy savings.;

    Abstract : Popular Abstract in English Energy savings and climate change mitigation have been discussed in the world since the oil crisis in the 1970s and the building sector has been seen as one of the largest contributors to global warming effects in the world. Energy efficiency in buildings is a critical issue to be addressed in order to reduce electricity energy used in buildings and is one of the main tasks that is developed within the program Advancing Sustainable Construction in Mozambique.

  4. 4. Process Utility Performance Evaluation and Enhancements in the Traditional Sugar Cane Industry

    University dissertation from KTH Royal Institute of Technology

    Author : Eyerusalem Deresse Birru; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sugar cane; energy saving; heat loss; steady state; transient state; CO2 emission; absorption chiller; pellet; bagasse drying; energy perfor-mance; traditional mills; modern mills; waste water; surplus power; Energiteknik; Energy Technology;

    Abstract : The need to achieve sustainable development has led to devising various approaches for the efficient utilization of natural resources. Renewable energy technology and energy efficiency measures feature prominently in this regard, and in particular for industries such as sugar production:  the sugar cane industry’s eponymous feedstock is a renewable resource, and mills have potential for increased energy savings via improvements to cogeneration units, electric drive retrofitting, and other measures.

  5. 5. Building as active elements of energy systems

    University dissertation from Västerås : Mälardalen University

    Author : Mehmet Börühan Bulut; Mälardalens högskola.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smart grid; smart home; cooperation; energy; buildings; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Buildings account for approximately 40% of the energy demand and 33% of the total greenhouse gas emissions in the European Union. Accordingly, there are several efforts that target energy efficiency in buildings both at the European and Swedish levels. The role of buildings in climate change mitigation, however, is not limited to energy savings. READ MORE
