APOLUX 1.0 is a computer code specifically developed for assisting the architect regarding daylighting considerations; it runs in a threedimensional graphic environment, accepts files from graphic editors and uses models physically consistent for data treatment. It was developed aiming its integration to the architect's design praxis.
Dedicated outdoor air systems (DOAS) have been proposed to treat the outdoor air before it enters the building and thus reduce the load on the zone equipment. This paper presents a study of different DOAS configurations and their energy and power consumptions for multiple climates of the United States. Based on the simulation results, the DOAS showed promise in reducing energy consumption relative to the baseline system in the office building in all climates studied.
The Haima is a non air-conditioned 16,000 m2 tent designed to house fifteen exhibitions about conditions for peace, viewed as solutions to economic, cultural and environmental conflict, during the Barcelona Forum 2004. The Haima is composed of several tents connected to each other’s and to the exterior environment through large openings. The whole structure is placed on the middle of a large square, next to the Mediterranean Sea.
In early 1980s, Tsinghua University has started to develop a new building simulation tool with the aims to benefit for teaching, research and practical use of HVAC related applications in China. With the concept of “base temperature” of a space, it provides a handy link between thermal behaviour of buildings and dynamic performance of HVAC systems. It emphases on finding the predicted ideal performance of a system and compare with the user selected design conditions of a space, ie the degree of satisfaction, rather than go straight to find the size and capacity of the system.
Radiant cooling systems for thermal comfort in commercial buildings are new to North America. The University of Calgary’s ICT Building has a hybrid radiant slab-mixed air system that offers an opportunity to evaluate operating performance. Through integrated field measurements and building simulation with EnergyPlus, it was found that the building energy performance could be improved by reducing conflicts between systems, especially simultaneous heating and cooling.
Accurate assessment of both surface and interstitial condensation risk at the design stage of buildings is of great importance - not just to minimise the damaging effects moisture can cause to building envelopes, but also to contribute to the provision of adequate indoor air quality. Guidance certainly does exist with regards to limiting thermal bridging in order to prevent condensation occurring on new constructions.
This paper explores the degree to which subjective assessments of the acoustical properties of a real space can be reproduced by assessments that are based on computational auralization. Toward this end, three spaces with different functional and acoustical characteristics were selected. These spaces were evaluated by a group of test participants. A second group of test participants evaluated high quality auralizations of the spaces.
This paper addresses the application of fire and smoke simulation and computational fluid dynamics tools to events taking place in the new engineering building on the campus of the University of Montreal. The development steps include 3D CAD modeling of the entire building, geometry transfer and airflow, and fire simulation with enhanced rendering considering the optical properties of smoke and fire. The Fire Dynamics Simulator solver developed at NIST has been used to generate the necessary data for the fire visualization.
This paper deals with solar indicators and simulation as a step toward global assessment of a district. The final aim is to assess district projects as much exhaustively as possible, including among other things energy aspects, acoustic aspects, emissions… The present article deals only with solar aspects. First are presented the key indicators regarding solar aspects. Next, solar simulations are run at the scale of the district with the SOLENE software.
