1. 1. Exploring spatial and temporal resolution in energy systems modelling : a model-based analysis focused on the developing electricity systems

   Författare :Nandi Moksnes; Viktoria Martin; Mark I. Howells; William Usher; Holger Rogner; Hannah Daly; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system optimisation modelling; Global sensitivity analysis; Robust decision methods; Geospatial electrification model; SDG7; SDG13.; Energisystem; optimering; energimodellering; Global känslighetsanalys; Robust decision methods; geospatial elektrifieringsmodell; Globala mål 7; Globala mål 13; Energiteknik; Energy Technology;

   Sammanfattning : The energy system is undergoing a transition in many parts of the world with this transition being driven by several factors such as climate change, and economic and social development. Agenda 2030, with its 17 Sustainable Development Goals (SDGs), has set the direction on where development should be focussed. LÄS MER

3. 2. A Systematic Approach to Integrated Building Performance Assessment and Visualisation

   Författare :Samer Hassanie; Ivo Martinac; Holger Wallbaum; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal comfort; energy consumption; building certifications; occupancy; modeling; presence; pattern recognition; Demand controlled ventilation; Indoor thermal environment; Occupancy; Time response; Energy use; Civil and Architectural Engineering; Byggvetenskap;

   Sammanfattning : The aim of this project was to develop a holistic approach to building-performance assessment without limiting it to energy use (usually expressed in kWh/m2/year), but rather include more parameters that represent the following aspects: Economic, environmental, and quality of service provided to the occupant/client. If it can be shown that buildings can be operated not only in an energy-efficient way, but also in a way that takes into consideration the needs of the occupants, a case could be built that a higher quality of indoor environment does not necessarily mean a higher economic impact.

4. 3. End-user activity-based service design in the built environment context : Exploring everyday life in KTH Live-in-Lab

   Författare :Elena Malakhatka; Per Lundqvist; Marco Molinari; Shaun West; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; service design; human activity system; building system; service system; actors network analysis; living lab; sustainable building; Energy Technology; Energiteknik; Building Service and Energy Systems; Installations- och energisystem;

   Sammanfattning : The main goal of this thesis is to communicate the motivation, process, and result of the research project dedicated to exploring the topic of Service Design, based on end-user activities analysis in the built environment context. We have elected to use a KTH Live-in-Lab as a testbed in relation to the chosen living lab network of actors and stakeholders. LÄS MER

5. 4. Optimisation of Local and National Energy Systems : Development and Use of the MODEST Model

   Författare :Dag Henning; Carl-Johan Fogelholm; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Energy may be supplied by a multitude of components. Computer simulation helps in finding a beneficial system design. The energy-system optimisation model MODEST has been developed, and it has been applied to municipal, regional, and national energy systems. LÄS MER

7. 5. Prediction of power and energy use in dwellings : Addressing apects of thermal mass and occupant behaviour

   Författare :Victor Fransson; Avdelningen för Installations- och klimatiseringslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadssimulering; Termisk massa; Värmetröghet; boendes beteende; hushållsel; varmvatten; building simulation; thermal mass; thermal inertia; occupant behaviour; household electricity; domestic hot water;

   Sammanfattning : Households are responsible for approximately 26 % of the annual energy use in the EU. Following the EU-directives regarding energy performance in buildings, international initiatives have been taken in Europe to help countries to define and include guidelines in their own building codes, for example, to establish the concept of zero energy buildings, ZEBs.
