  2. 1. Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort

    Author : Jonathan Karlsson; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; aggregates; heat capacity; thermal properties; thermal conductivity; thermal inertia; thermal mass; time constant; Energy storage;

    Abstract : The aim of this project was to generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers. This could include buildings that can function without energy input during cold periods, buildings that give a robust indoor climate without installed cooling, and buildings with good thermal comfort also in case of higher outdoor temperatures resulting from global warming.

    Author : Saman Nimali Gunasekara; Viktoria Martin; Justin NingWei Chiu; Torsten Fransson; Ana Ines Fernandez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage TES ; phase change material PCM ; phase diagram; congruent melting; compound; solid solution; eutectic; peritectic; Energy Technology; Energiteknik; Teknisk materialvetenskap; Materials Science and Engineering; Chemical Engineering; Kemiteknik;

    Abstract : Climate change is no longer imminent but eminent. To combat climate change, effective, efficient and smart energy use is imperative. Thermal energy storage (TES) with phase change materials (PCMs) is one attractive choice to realize this. READ MORE

  5. 3. Energy Efficiency through Thermal Energy Storage : Possibilities for the Swedish Building Stock

    Author : Johan Heier; Viktoria Martin; Chris Bales; Signhild Gehlin; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; buildings; energy efficiency; energy savings; peak load reduction; Swedish building stock; termisk energilagring; byggnader; energieffektivisering; energibesparing; toppbelastningsutjämning; Sveriges byggnadsbestånd; Värmelagring i byggnader;

    Abstract : The need for heating and cooling in buildings constitutes a considerable part of the total energy use in a country and reducing this need is of outmost importance in order to reach national and international goals for reducing energy use and emissions. One important way of reaching these goals is to increase the proportion of renewable energy used for heating and cooling of buildings. READ MORE

  6. 4. Load Shifting and Storage of Cooling Energy through Ice Bank or Ice Slurry Systems : modelling and experimental analysis

    Author : Marino Grozdek; Per Gunnar Lundqvist; Michael Kauffeld; KTH; []

    Abstract : Ice based Cool Thermal Energy Storage (CTES) systems have attracted much attention during last few decades. The reasons are mainly of economical and environmental nature. READ MORE

  7. 5. Avoiding greenhouse gas emissions using flexibility in smart thermal grids

    Author : Jay Hennessy; Hailong Li; Justin Chiu; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; thermal grids; flexibility; avoided emissions; thermal storage; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The Paris Agreement on climate change entered into force in 2016 and has been ratified by 193 of the 197 Parties to-date, followed by country targets to cut greenhouse gas emissions, not least through an increasing penetration of renewable energy sources. In its 2021 annual World Energy Outlook, the IEA envisages a Net-Zero Emissions by 2050 scenario (NZE) in which renewables as a percentage of total energy supply increase from around 10% in 2020 to over 65% in 2050 and is reflected by a similar change in the percentage of variable renewables in total generation, thereby increasing the need for system flexibility.
