2. 1. Modelling and Intelligent Climate Control of Buildings

   Author : Mohsen Soleimani Mohseni; Bertil Thomas; Lennart Jagemar; Geoffrey Levermore; Chalmers University of technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural networks; indoor climate control; operative temperature; demand controlled ventilation; prediction; feed-forward control;

   Abstract : The main purpose of the work presented in this thesis is to examine the possibilities of different control techniques together with intelligent building technology to improve the indoor climate and/or the energy efficiency of buildings. In particular, the possibilities of measuring more variables and using them as input to the controllers are examined. READ MORE

4. 2. Energy efficient indoor climate control - A practical approach for enhanced implementability

   Author : Mattias Gruber; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model-based control; building automation; ventilation and air-conditioning; office buildings; implementability; energy efficiency; Heating; indoor climate control;

   Abstract : This work deals with energy efficient indoor climate control in office buildings, with an emphasis on implementability. More specifically, the aim is to suggest and evaluate improvements to building automation systems that are sufficiently simple and efficient to be realistic alternatives to commonly-used systems.

5. 3. 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

   Author : Mattias Gruber; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Decision making on indoor climate control in historic buildings : knowledge, uncertainty and the science-practice gap

   Author : Gustaf Leijonhufvud; Tor Broström; Simon Stefan; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; Preventive conservation Environmental control; Energy efficiency; Decision-making; Knowledge sharing; Preventive conservation; Environmental control; Energy efficiency; Decision-making; Knowledge sharing;

   Abstract : Balancing use, preservation and energy use is a fundamental challenge for the whole heritage field. This is put to the point in designing and operating systems for indoor climate control in historic buildings, where competing objectives such as preservation, comfort, accessibility, energy use and cost have to be negotiated in the individual case.

7. 5. On the Feasibility of Reinforcement Learning in Single- and Multi-Agent Systems : The Cases of Indoor Climate and Prosumer Electricity Trading Communities

   Author : Ross May; Kenneth Carling; Mengjie Han; Xingxing Zhang; Zoltán Nagy; Högskolan Dalarna; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Reinforcement Learning; Multi-Agent Reinforcement Learning; Buildings; Indoor Climate; Occupant Comfort; Positive Energy Districts; Peer-to-Peer Markets; Complex Adaptive Systems;

   Abstract : Over half of the world’s population live in urban areas, a trend which is expected to only grow as we move further into the future. With this increasing trend in urbanisation, challenges are presented in the form of the management of urban infrastructure systems. READ MORE
