1. 1. Modelling Energy Conservation and CO2 Mitigation in the European Building Stock

   Författare :Erika Mata Las Heras; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost assessment; bottom-up building modelling; techno-economical potentials; archetype building; energy conservation measures; European building stock;

   Sammanfattning : This thesis investigates energy conservation in building stocks with the aim of developing a methodology that can be applied to the national building stocks of the European Union (EU). For this purpose, a bottom-up building-stock model and a methodology for describing the building-stock have been established. LÄS MER

3. 2. Modelling drivers of energy demand in the European Union building sector

   Författare :Eoin Ó Broin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EU; Elasticities; Heating; Policy; Bottom-up; Top-down; Efficiency; Residential;

   Sammanfattning : In the context of ongoing initiatives within the European Union (EU) to tackle global warming and to secure future energy supplies, the building sector is often cited as offering strong potential for energy savings. The primary aims of this thesis are to analyse the historical data related to EU building and to generate scenarios that highlight the technical and non-technical parameters that affect the energy demands (and thereby the potentials for savings) of the building sector.

4. 3. Towards Environmental Informatics for Building Stocks. A Conceptual Model for an Environmental Building Stock Information System for Sustainable Development - EBSIS

   Författare :Liane Thuvander; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building stock; information system; environmental system analysis; energy flows; building stock information system; material flows; environmental informatics; urban system analysis; environment; sustainable sevelopment;

   Sammanfattning : The Swedish building sector uses a considerable amount of all materials and all energy used in Sweden. Knowledge about the existing building stock, its impact on the environment related to the use of material and energy, however, is limited and target settings for environmental objectives and decision making are based on vague information.

5. 4. A comprehensive approach to building-stock modelling - Assessing the impact of renovating urban housing stocks

   Författare :Magnus Österbring; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy performance certificate; costeffectiveness; GIS; LCA; building valuation; renovation; refurbishment; Building-stock modelling; multi-family buildings; energy;

   Sammanfattning : The existing building stock provide a possibility for cost-efficient energy efficiency measures and related reductions in greenhouse-gas emissions. As the rate of renewal in the buildingstock is low, energy efficiency measures need to be applied when renovation is being done in order to reach climate goals. LÄS MER

7. 5. Nanowire Transistors and RF Circuits for Low-Power Applications

   Författare :Karl-Magnus Persson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :InAs; Nanowire; Metal-oxide-semiconductor field-effect transistor; MOSFET; RF; Mixer; Circuit; 1 f-noise; Simulation; Modelling;

   Sammanfattning : The background of this thesis is related to the steadily increasing demand of higher bandwidth and lower power consumption for transmitting data. The work aims at demonstrating how new types of structures, at the nanoscale, combined with what is referred to as exotic materials, can help benefit in electronics by lowering the consumed power, possibly by an order of magnitude, compared to the industry standard, silicon (Si), used today.
