2. 1. Thermal system analysis of embedded building integrated heating - Numerical model and validation of hydronic floor heating systems

   Author : Henrik Karlsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiant heating; floor heating; low temperature hydronic heating; whole building thermal system analysis; Simulink modelling; Building integrated heating;

   Abstract : A numerical simulation tool for building integrated heating (BIH) systems is developed. BIH is defined as a heat supply system that maintains the indoor thermal comfort within acceptable limits by means of a controlled heat supply to the inner of the building envelope/structure.

4. 2. Applicability of thermal energy storage in future district heating system - Design methodologies and performance evaluations

   Author : Yichi Zhang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature district heating; demand-side management; low energy buildings; Thermal energy storage; district heating; variable renewable energy;

   Abstract : District heating (DH) enables efficient and economical utilization of energy resources to satisfy the heat and hot water demands in buildings and is, thereby, well-established in Northern European countries. To achieve the future renewable energy system, the current DH systems are proved to undergo transitions towards the future DH systems, with major characteristics including renewable-based heat sources, low temperature networks, lower heating demands and smart controls.

5. 3. Heating and Cooling Requirements in Commercial Buildings. A duration curve model including building dynamics

   Author : Per-Erik Nilsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC system; cooling requirements; duration curve; heating requirements; commercial building; heat balance; balance curve; energy analysis;

   Abstract : In many European countries, especially, the heat loss due to transmission and air leakage, in many buildings today, is only a fraction of what it was in those built in the early 70's. At the same time there have been changes in the way the buildings are used which, among other things, has lead to an often considerable increase of the internal heat loads. READ MORE

6. 4. Industrial Construction Methods for Cost-Effective and Sustainable Multi-Storey Buildings

   Author : Hanif Pourghazian; Folke Björk; Anne Landin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

   Abstract : Reduction of the cost of construction is a constant goal for the building industry. One way of reducing the construction cost of buildings is to develop building technologies that will give increased productivity. Reduced construction time at the building-site and waste of materials and resources contribute to furtherreduction of the costs. READ MORE

7. 5. Heat demand profiles of buildings' energy conservation measures and their impact on renewable and resource efficient district heating systems

   Author : Lukas Lundström; Erik Dahlquist; Fredrik Wallin; Björn Karlsson; Jan Akander; Sven Werner; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; energy conservation; weather normalisation; typical meteorological year; building energy simulation; system analysis; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Increased energy performance of the building stock of European Union is seen as an important measure towards mitigating climate change, increasing resource utilisation efficiency and energy supply security. Whether to improve the supply-side, the demand-side or both is an open issue. READ MORE
