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. Feed-forward Control and Dynamic Modelling in Temperature Control of Buildings

   Author : Mohsen Soleimani-Mohseni; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building models; state space models; feedback; thermostats; transfer function models; intelligent buildings; ON-OFF controllers; Feed-forward; PIL controllers;

   Abstract : This thesis is mainly about the investigations of different control strategies (and in particular feed-forward) in order to improve indoor climate and/or save energy in buildings. One part of the thesis deals with different ways to obtain dynamic models for climate systems in buildings. READ MORE

   Abstract : The thesis focuses on the efficiency of the space heating system. In particular, the efficiency factors measure the efficiency of thermal zone. The efficiency factors measures how the energy is used in a space heating. READ MORE

7. 5. A regression approach for assessment of building energy performance

   Author : Jimmy Vesterberg; Thomas Olofsson; Mohsen Soleimani-Mohseni; Björn Reidar Sörensen; Sofia Lidelöw; Umeå universitet; []
   Keywords : building energy simulation; measurements; regression; calibration parameters;

   Abstract : Reliable evaluation methods is needed to ensure that investments in energy conservation measures (ECMs) and the construction of new energy efficient buildings lives up to the promised and expected performance.This thesis presents and evaluates a regression method for estimation of influential building parameters: transmission losses above ground (including air leakage), ground heat loss, and overall heat loss coefficient.
