2. 1. Energy efficiency and carbon dioxide mitigation in building stocks-

   Author : Erika Mata Las Heras; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis investigates the implementation of energy-saving measures (ESM) in existing building stocks from an energy systems perspective. The effects of the measures are assessed in terms of net and delivered energy levels, carbon dioxide (CO2) emissions, and the costs for implementing the measures. READ MORE

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

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

   Abstract : 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. READ MORE

5. 3. Application of Synthetic Biology for Biopolymer Production using Saccharomyces cerevisiae

   Author : Alejandro Muñoz De Las Heras; Teknisk mikrobiologi; []
   Keywords : Saccharomyce cerevisiae; Xylose; Poly-3-d-hydroxybutyrate PHB ; NADH; NADPH; Acetyl-CoA; Metabolic engineering;

   Abstract : Plastics are versatile, cheap and durable materials that are omnipresent in modern society. Since most of them are derived from crude oil and are not biodegradable, their production leads to the depletion of fossil fuels and the accumulation of enormous amounts of plastic waste that pollutes ecosystems worldwide.
