An experimental low-energy house, with a novel structure incorporating an unusually large amount of expanded polystyrene insulation, was subjected to extensive monitoring while occupied by a family. Measured thermal conductances are reported and compared with calculated U-values, and the moisture performance is discussed.
The purpose of this paper is to show how the heating and ventilating plant of a lease building was designed. An optimal design was achieved by utilizing the building's thermal inertia for both winter and summer operations.
With a dynamical model, the thermal behavior of a single office room is simulated. The model includes among other things the behavior of occupants, the heat production of machines and lights, the heat flux into masses, real weather data (hourly observations) and different HVAC and control systems. The computer program calculates monthly and yearly energy consumption and a statistical distribution of the room air temperature. It can also be used to investigate the time evolution of physical processes for short periods.
This paper describes tests of thermal and ventilation performance of two relatively new occupant-controlled localized thermal distribution (also called task ventilation) systems. The first is a raised-floor distribution system providing air through grilles in the floor panels, and the second is a desk-mounted unit supplying conditioned air at desktop level. These systems have been tested in a mockup of a typical partitioned open-plan office, and the resulting temperature and air velocity distributions are reported for a variety of system and locally controlled conditions.
