  2. 1. Risk Assessment of Hygrothermal Performance - Building Envelope Retrofit

    Author : Simon Pallin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; retrofit; Risk; hygrothermal; simulations.; residential; mold; energy savings;

    Abstract : A risk assessment of the hygrothermal performance for a building envelope retrofit investigates possible variations in energy performance, indoor environment quality and moisture safety and elaborates on the risks of exceeding defined acceptance criteria. These risks can be properly determined if including the variability of, by the investigated retrofit, most influencing parameters. READ MORE

  4. 2. Optimum Design of Heat Exchanger Networks in Retrofit Situations

    Author : Annika Carlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimum design; pressure drop; process integration; pinch thechnology; heat transfer coefficients; heat exchanger networks; retrofit;

    Abstract : Today, the most important activity in heat exchanger network synthesis is the retrofitting, rather than grass-root design, of networks. There is a vast potential for energy improvement in many processes by increasing the level of internal heat exchange. READ MORE

  5. 3. Process Integration of Industrial Heat Pumps in Grass-Root and Retrofit Situations

    Author : Erik Wallin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; pinch technology; retrofit; industrial heat pumps; grass-root;

    Abstract : In several works, methods for process integration of heat pumps (HPs) have been developed, which in turn have been used for case studies in different industrial types. HP integration has thus proven to be a promising technique for utility savings and attractive payback periods. READ MORE

  6. 4. Structural health of bridges : monitor, assess and retrofit

    Author : Arvid Hejll; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The research presented in this Licentiate thesis is intended to cover minor areas of the wide research area Structural Health Monitoring (SHM) of Civil Engineering Structures. SHM is broadly the knowledge maintaining our infrastructure by assessing the condition, often by monitoring or measurements, diagnose damages, analyse risk levels, by using inputs from measurements and diagnoses, and in the end retrofit, if needed.

  7. 5. Vibration mitigation of high-speed railway bridges : Application of damping devices in theory and practice

    Author : Sarah Tell; Raid Karoumi; Andreas Andersson; Ülker-Kaustell Mahir; José Maria Goicolea; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration mitigation; high-speed railway bridges; damping devices; retrofit; numerical analysis; hybrid simulation; field experiment; vibrationsdämpning; järnvägsbroar för höghastighetståg; dämpare; eftermonteringsmetod; numerisk analys; hybridsimulering; fältförsök; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The dynamic response of railway bridges is an important aspect to consider, as the repetitive loading from passing trains may result in excessive vibrations of the bridge deck. Several design criteria are developed in order to assure the structural safety and passenger comfort during train crossings of a bridge. READ MORE
