1. 1. Wetting and drying of aerogel-based coating mortars in Swedish climates

   Författare :Ali Naman Karim; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; runoff; Aerogel; retrofitting; coating mortar; wetting; drying; wind-driven rain; render;

   Sammanfattning : Aerogel-based coating mortars (ACMs) have emerged as energy-efficient wall finishes with thermal conductivities of 30–50 mW/(m∙K). These coating mortars represent a promising alternative to traditional thermal insulation materials for retrofitting uninsulated building envelopes particularly in culturally significant structures.

3. 2. Simulation of Combustion and Fire-Induced Flows in Enclosures

   Författare :Heimo Tuovinen; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cumbustion; Chemical kinetics; Flamelet model; CFD models; Fire-induced flows;

   Sammanfattning : Numerical modeling of combustion in flames and gas flows and gas flows generated by fires in compartments has been carried out. The laminar flamelet model has been used to model combustion in different degrees of vitiation in order to model fire gas recirculation which occurs in compartment fires. LÄS MER

4. 3. Early Stage Architectural Design Practice Perspectives on Life Cycle Building Performance Assessment

   Författare :Toivo Säwén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Early design stages; Participatory software development; Ethnographic interview; Literature review; Life cycle assessment; Building performance; Architecture;

   Sammanfattning : Architectural practitioners can avoid negative social and environmental impacts of new construction by making decisions supported by impact quantification during design processes. However, most software tools developed for such quantification see little use in practice, especially in early design stages when decisions have the greatest influence. LÄS MER

5. 4. Contaminant transport by air infiltration from crawl space to occupant area: Numerical simulations and field measurements in Swedish schools

   Författare :Fredrik Domhagen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crawl space; contaminants; infiltration model; monte carlo method; airtightness; air permeability;

   Sammanfattning : Some Swedish school buildings built in the 1960’s and 1970’s have indoor air quality problems. Many of these buildings have a crawl space from which contaminants are suspected to originate. The poor indoor air quality cause discomfort among pupils and teachers and a solution to the problem is not always found. LÄS MER

7. 5. Reinforcement in Tailor-made Concrete Structures

   Författare :David Fall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailor-made concrete structures; Steel fibre reinforcement; Automated production; Geometrically complex structures; Reinforcement alternatives;

   Sammanfattning : In tailor-made concrete structures of complex geometries, the formability of concrete is an asset. To use this formability in load-bearing structures, the concrete needs to be reinforced. During the past century steel bars were used; however, in recent decades, alternative reinforcement methods have been introduced. LÄS MER
