1. Evaluation of new active technology for low-energy houses
Abstract : Using energy at low-quality levels opens up new possibilities for low-energy houses. Low-quality energy can be heat at a temperature that is close to that of its surrounding, and can be used, for example, to pre-heat ventilation air or domestic hot water. READ MORE

2. Increasing the value of household appliances by adding a heat pump system
Abstract : Historically, domestic tasks such as preparing food and washing and drying clothes and dishes were done by hand. In a modern home many of these chores are taken care of by machines such as washing machines, dishwashers and tumble dryers. READ MORE

3. Low-Temperature Baseboard Heaters in Built Environments
Abstract : The European Union has adopted a plan to decrease 20 % of total energy consumption through improved energy efficiency by 2020. One way of achieving this challenging goal may be to use efficient water-based heating systems supplied by heat pumps or othersustainable systems. READ MORE

4. Assessment of existing and potential developments of district-heating systems
Abstract : District heating (DH) may play an important role for achieving the EU goal of a secure, competitive and sustainable energy supply. DH benefits from the possibilities of utilising local resources such as municipal solid waste and other low-quality fuels, as well as low-cost waste heat from industries and from combined heat and power plants (CHP).

5. 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
