1. Thermal system analysis of embedded building integrated heating - Numerical model and validation of hydronic floor heating systems
Abstract : A numerical simulation tool for building integrated heating (BIH) systems is developed. BIH is defined as a heat supply system that maintains the indoor thermal comfort within acceptable limits by means of a controlled heat supply to the inner of the building envelope/structure.

2. Thermal Modelling of Water-Based Floor Heating Systems - supply temperature optimisation and self-regulating effects
Abstract : Low temperature water-based concrete embedded floor heating systems are studied. The utilisation of low quality heat sources is facilitated by low temperature heating. Theoretical models which describe the transient thermal floor heating operation constitute the basis for the analysis. READ MORE

3. Applicability of thermal energy storage in future district heating system - Design methodologies and performance evaluations
Abstract : District heating (DH) enables efficient and economical utilization of energy resources to satisfy the heat and hot water demands in buildings and is, thereby, well-established in Northern European countries. To achieve the future renewable energy system, the current DH systems are proved to undergo transitions towards the future DH systems, with major characteristics including renewable-based heat sources, low temperature networks, lower heating demands and smart controls.

4. Integrated Control of Heat Pumps
Abstract : The purpose of the work presented in this thesis is to investigate the potential and prerequisites for improved energy efficiency of heat pump systems using efficient components and proper methods for optimisation of operation. The background is that several investigations have reported on possibilities for increased energy efficiency of heat pumps if variable-speed capacity control is used instead of conventional on/off control.

5. Multi-dimensional approach used for energy and indoor climate evaluation applied to a low-energy building
Abstract : The building sector alone accounts for almost 40% of the total energy demand and people spend more than 80% of their time indoors. Reducing energy demand in buildings is essential to the achievement of a sustainable built environment. At the same time, it is important to not deteriorate people’s health, well-being and comfort in buildings. READ MORE
