1. 1. Demand based control of indoor climate in office buildings. Design of local and central feed-forward control systems for high comfort, low energy use and low peak power

   Författare :Mattias Gruber; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; demand based control; IAQ; central control; local control; disturbance rejection; thermal climate; HVAC; energy efficiency; feed-forward; Building services engineering; office buildings;

   Sammanfattning : In this work, a number of novel strategies for controlling the heating, ventilation and air-conditioning (HVAC) systems in office buildings have been designed and evaluated. The purpose of the control strategies is to improve the match between what is supplied by the HVAC-systems and what is required to achieve a desirable indoor climate in the building. LÄS MER

3. 2. New opportunities provided by the Swedish electricity meter reform

   Författare :Fredrik Wallin; Erik Dahlquist; Eva Thorin; Peter Roots; David Natusch; Mälardalens högskola; []
   Nyckelord :automatic meter reading AMR ; advanced metering infrastructure AMI ; peak load; consumption patterns; visualize; consumption feed-back; added values; demand-based; tariffs; bottom-up modeling; web-based applications; TECHNOLOGY; TEKNIKVETENSKAP; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : The reduction of the impact of energy consumption is a priority issue and a major challenge that concerns every country in the world. This is a complex task that needs to be tackled from several angles in the search for areas where optimizations and savings can be made. LÄS MER

4. 3. Boosting behavioral change in residential electricity consumption : demand response programs and feedback

   Författare :Cajsa Bartusch; Lars Wester; Monica Odlare; Thomas Porathe; Mikael Larsson; Kajsa Ellegård; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : As part of realizing national and European climate ambitions, it is imperative to bring about increased energy efficiency and consumption flexibility in the residential sector of the Swedish power market. In addition to governmental policy instruments to this end, market-based measures play an important role in making behavioral change in domestic electricity use happen. LÄS MER

5. 4. Restructured district heating price models and their impact on district heating users

   Författare :Jingjing Song; Björn Karlsson; Fredrik Wallin; Hailong Li; Heimo Zinko; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; restructured price model; price model survey; pricing strategy; consumption profile; consumption pattern; alternative cost; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : District heating (DH) is considered to be an efficient, environmentally friendly and cost-effective method for providing heat to buildings, since electricity is usually co-generated in biomass fuelled combined heat and power (CHP) plants. This gives it an important role in the mitigation of climate change. LÄS MER

7. 5. Combined solar and pellet heating systems : Studies of energy use and CO-emissions

   Författare :Frank Fiedler; Högskolan Dalarna; []
   Nyckelord :Pellet and solar heating systems; CO-emissioins;

   Sammanfattning : In this study 4 solar and pellet heating systems have been studied with the help of annual dynamic simulations. Two of the systems comprised a pellet stove and two systems were solar combisystems; one with a store integrated pellet burner, the other with a separate pellet boiler. LÄS MER
