Calorimetric measurement of indoor sunshields
Because of the sun irradiation the incorrect dimensioning of a house can lead to excessive internal temperatures. Cooling is a common solution, but this consumes a large amount of energy. Preventing the entry of solar radiation into the building is a better solution. The main question is, which thermal effect (gand Uvalue) curtains and blinds have on the internal room temperature and cooling energy, due to less sun irradiation.
NEW FULL-SCALE SOLAR AND BUILDING ENERGY LABORATORY AT LUND UNIVERSITY
Abstract – A new full-scale laboratory has been erected at Lund university in 2004. The main goal of the laboratory is to find cost-effective solutions which reduce the electricity use in offices and residential buildings. The facility contains four rooms for testing building components, especially glazing and shading systems. The roof has a platform for testing solar components and solar systems, both solar heating and photovoltaic systems. The four test rooms are placed in a climatic chamber, a guard ,which is temperature controlled. The rooms are constructed of homogeneous insulated sandwich panels with low thermal mass and no thermal bridges and have removable facades towards south. The rooms are identically two and two: One pair is designed for studies of visual and thermal comfort and have modern office ventilation and lighting systems. The other room pair is designed for detailed studies of the energy performance of i.e. solar shading systems. The heating system of the laboratory is based on a combination of a ground source heat pump and solar thermal collectors. Both high temperature and low temperature solar collectors can be connected to the system to produce hot water or recharge the ground source borehole. Separate collector test loops will also be installed for investigation of solar thermal and hybrid PV-T collectors. Operating temperatures from below the dew point of the air to high temperatures (90°C) can be simulated in these systems. A building automation system together with a traditional logger system will be used for both long-term and short-term monitoring. (Less)
Philip Roth’s Great Books: A Reading of The Human Stain
Philip Roth belongs to the first generation of American novelists for whom a university education in the liberal arts was the norm. This essay charts Roth’s developing acquaintance with classical literature, the starting point for Great Books courses in the 1950s, and the implications for his fiction of his understanding of the difference in scope and purpose between the two representative classical genres. It focuses on The Human Stain (2000), the novel in which he reflects most directly upon what tragedy and epic once did, and what might happen to novels if they became more like the one or the other.
