  1. 1. Energy efficiency and the challenge of climate change - Studies of the Swedish building sector

    Author : Jonas Nässén; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology diffusion; input-output analysis; Energy efficiency; Swedish building sector; carbon dioxide;

    Abstract : The interrelated environmental, social and economic challenges imposed by global climate change will make it one of the central political issues in the coming century. Use of fossil fuels is the largest source of anthropogenic CO2 emissions and hence the transformation of the energy system plays a central role in the mitigation of future climate change. READ MORE

  2. 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; [2012]
    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

  3. 3. Modularity in industrialised timber housing a lean approach to develop building service systems

    Author : Martin Lennartsson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : Modularity has been applied in various disciplines, e.g. manufacturing, computer, cognitive science and education. General advantages are platform thinking and module variants which provide a range of product variants using a small number of components. READ MORE

  4. 4. Towards sustainability with building services systems : – by focusing on material choices, energy use and thermal indoor climates in residential buildings

    University dissertation from Avd Installationsteknik, LTH, Lunds universitet

    Author : Mats Dahlblom; [2020-03-12]

    Abstract : For a development to be considered sustainable, social, economic and environmental requirements must be met. The Swedish sustainable development goals, based on Agenda 2030, contain 16 national environmental quality goals. The National Board of Housing, Building and Planning is responsible for achieving the goal "A good built environment". READ MORE

  5. 5. Ventilation and window opening in schools, Experiments and Analysis

    University dissertation from Lund University, Lund Institute of Technology, Division of Building Services, P.O. Box 118, SE-22100 LUND, Sweden

    Author : Birgitta Nordquist; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat exchanger efficiency; duct design; balancing; disturbance; tracer gas measurements; analytical model; window opening; single-sided ventilation; ventilation; schools; sensitivity analysis; Building construction; Byggnadsteknik;

    Abstract : The objective of this thesis is to study the application of ventilation in schools buildings. A number of studies of the application of different forms of ventilation are presented. The main part of the thesis focuses on window opening in a classroom. Analytical models for calculation of the air change caused by window airing are proposed. READ MORE
