1. 1. Extensive green roofs in Porto Alegre, Brazil : Effect on indoor thermal comfort in residential buildings

   Författare :Lisandra Fachinello Krebs; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Computer simulations; Extensive green roofs; Housing projects; Indoor thermal comfort; Leaf area index; Microclimate; Social housing; Sustainability; Thermal comfort;

   Sammanfattning : Brazil had a significant quantitative housing deficit of 7.7 million residences in 2015, especially in low-income housing. Traditionally, these projects have low levels of thermal insulation which can result in discomfort caused by warmth or cold. The residential sector is responsible for a significant part of the energy use in Brazil. LÄS MER

3. 2. Latent Heat Thermal Energy Storage for Indoor Comfort Control

   Författare :NingWei Justin Chiu; Viktoria Martin; Motoi Yamaha; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Phase Change Material; Indoor Comfort; Heat Transfer; Termisk Energilagring; Fasändringsmaterial; Inomhuskomfort; Värmeöverföring;

   Sammanfattning : Equating Earth’s existence to 24 hours, we, the Homo sapiens, came about in the last four seconds. Fossil fuel came to our knowledge with mass extraction dating from the Industrial Revolution two centuries ago, in other words 4 milliseconds out of Earth’s 24-hour equivalent lifetime. LÄS MER

4. 3. Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort

   Författare :Jonathan Karlsson; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; aggregates; heat capacity; thermal properties; thermal conductivity; thermal inertia; thermal mass; time constant; Energy storage;

   Sammanfattning : The aim of this project was to generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers. This could include buildings that can function without energy input during cold periods, buildings that give a robust indoor climate without installed cooling, and buildings with good thermal comfort also in case of higher outdoor temperatures resulting from global warming.

5. 4. Indoor Environment and User Perception. A Field Study in a Hospital Ward

   Författare :Jennie Skoog; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indoor environment; thermal climate; hospital ward; indoor air quality; comfort; perception; sound; light;

   Sammanfattning : The research on indoor environment has become more important and extensive the last decades. There is, however, a lack of studies made in buildings with two or more distinct groups of people. This study deals with hospital wards, which are a prime example of buildings occupied by more than one homogenous group of people. LÄS MER

7. 5. Indoor Thermal Environment in Supermarkets. A study of measured and perceived comfort parameters

   Författare :Ulla Lindberg; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigeration systems; supermarket; display cabinets; thermal comfort; thermal environment; interdisciplinary;

   Sammanfattning : In the supermarket environment three different groups must be considered: food (food quality), personnel (working conditions) and customers. Customers are of particular interest since they make up the commercial basis for the supermarket. Currently, however, there are no recommendations on the indoor environment for this category. LÄS MER
