1. Energy use and environmental impact from hotels on Adriatic Coast in Croatia : current status and future possibilities for HVAC systems
Abstract : This thesis analyses a specific type of energy usage system, “energy usage in hotels”, and how this system behaves. In order to evaluate the current state of energy use in hotels, an energy audit questionnaire was developed and conducted among 31,5% of hotels on the Adriatic coast. READ MORE

2. Modelling the dynamics of domestic low-temperature heat pump heating systems for improved performance and thermal comfort : a systems approach
Abstract : The present environmental concerns and the rising human requirement for solutions with better comfort and lower costs have resulted in an increased awareness for the energy use in the built environment. Technical advances in building structural systems and materials, heating and other comfort-providing systems and controlling strategies all lead to the integration of building technology with the function of buildings and the aesthetics.

3. Predicting flow-generated noise from HVAC components
Abstract : More energy efficient fans, i.e. larger sizes running at lower speeds, in Heating Ventilation and Air Conditioning (HVAC) systems decrease the fan noise and increase the importance of flow generated noise in other system components, e.g. READ MORE

4. Air - for Health and Comfort, An Analysis of HVAC Systems' Performance in Theory and Practice
Abstract : One part of the objective is to analyze how different ventilation systems perform in practice when it comes to supplying and exhausting designed air flow in different outdoor and indoor conditions. The other part is to analyze the design criterias and the energy use of a variable air volume system based on controlled static pressure at the branch duct level and supplying outdoor air only.

5. Modelling Life Cycle Cost for Indoor Climate Systems
Abstract : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial cost. A life cycle approach could improve both the economic and environmental performance since the energy use could decrease. READ MORE
