2. 1. Urban building energy modeling : A systematic evaluation of modeling and simulation approaches

   Author : Fatemeh Johari; Joakim Widén; Joakim Munkhammar; Olga Kordas; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban building energy modeling; Urban energy Planning; Bottom-up energy modeling; Thermal zoning; Model complexity;

   Abstract : Urban energy system planning can play a pivotal role in the transition of urban areas towards energy efficiency and carbon neutrality. With the building sector being one of the main components of the urban energy system, there is a great opportunity for improving energy efficiency in cities if the spatio-temporal patterns of energy use in the building sector are accurately identified.

4. 2. Petroleum Production and Exploration : Approaching the End of Cheap Oil with Bottom-Up Modeling

   Author : Kristofer Jakobsson; Kjell Aleklett; Roger Bezdek; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The theme of this thesis is the depletion of petroleum (crude oil and natural gas). Are there reasons to be concerned about an ‘end of cheap oil’ in the near future? There is a lively debate regarding this issue. The debate is sometimes described as a clash of ‘concerned’ natural scientists and ‘unconcerned’ economists. READ MORE

5. 3. Material metabolism of residential buildings in Sweden: Material intensity database, stocks and flows, and spatial analysis

   Abstract : Construction materials are used for the expansion and maintenance of the built environment. In the last century, construction material stock has increased globally 23-fold. READ MORE

6. 4. New opportunities provided by the Swedish electricity meter reform

   Author : Fredrik Wallin; Erik Dahlquist; Eva Thorin; Peter Roots; David Natusch; Mälardalens högskola; []
   Keywords : automatic meter reading AMR ; advanced metering infrastructure AMI ; peak load; consumption patterns; visualize; consumption feed-back; added values; demand-based; tariffs; bottom-up modeling; web-based applications; TECHNOLOGY; TEKNIKVETENSKAP; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : The reduction of the impact of energy consumption is a priority issue and a major challenge that concerns every country in the world. This is a complex task that needs to be tackled from several angles in the search for areas where optimizations and savings can be made. READ MORE

7. 5. Bottom-Up Modeling of Building Stock Dynamics - Investigating the Effect of Policy and Decisions on the Distribution of Energy and Climate Impacts in Building Stocks over Time

   Author : Claudio Nägeli; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synthetic building stock; agent-based modeling; Building stock modeling; renewable energy; building stock dynamics; energy efficiency; GHG emissions;

   Abstract : In Europe, residential and commercial buildings are directly and indirectly responsible for approximately 30–40% of the overall energy demand and emitted greenhouse gas (GHG) emissions. A large share of these buildings was erected before minimum energy-efficiency standards were implemented and are therefore not energy- or carbon-efficient. READ MORE
