  2. 1. Design of Energy Efficient Buildings. Applied on HVAC Systems in Commercial Buildings

    Author : Lennart Jagemar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design; simulations; economic analysis; energy efficiency; commercial;

    Abstract : A methodology for planning and design of energy efficient buildings is presented and analysed. The starting point is the definition that energy efficiency is a question of minimizing the energy end-use within realistic economic frames and fully preserved function. The methodology is based on a systematic approach to the issue of energy efficiency. READ MORE

  4. 2. 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

  5. 3. Cooling demand in commercial buildings-The influence of building design

    Author : Hendrik Voll; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar factor; influence of design; cooling load; Commercial buildings; energy need; window share;

    Abstract : Large window areas and glass façades have become popular by architects. As the glass architecture has become fashionable in quite a short time it seems that the architects are not always aware of the energy consuming consequences that the highly glazed buildings, sometimes in combination with special room plans might cause.

  6. 4. Machine learning for building energy system analysis

    Author : Fan Zhang; Johan Håkansson; Chris Bales; Stefan Byttner; Högskolan Dalarna; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; district heating; machine learning; deep learning; HVAC; neural networks;

    Abstract : Buildings account for approximately 40% of the global energy, and Heating, Ventilation, and Air Conditioning (HVAC) contributes to a large proportion of building energy consumption. Two main negative characteristics that contribute to performance degradation and energy waste in an HVAC system are inappropriate control strategies and faults. READ MORE

  7. 5. Environmental Assessment of Air-conditioning Systems in Offices. Some Aspects Related to Design

    Author : Katarina Heikkilä; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air-conditioning; office buildings; environmental assessment; flexibility; weighting methods; comfort cooling system; energy efficiency; environmental performance; HVAC systems; life cycle assessment;

    Abstract : The primary function of an air-conditioning system, i.e. to fulfil given requirements on indoor climate in a specific building, can generally be achieved by several system designs. The systems may have varying environmental performance. READ MORE
