Large scale maps are available for many countries. The building ground plans of those maps can be helpful for the reconstruction of 3D building models from laser data and aerial images. This paper presents two studies on 3D building reconstruction. The first study combines data of a laser scanner with a high point density with the ground plans. The reconstruction approach is data driven. The se...

ABSTRACT: We apply CFD to visualize wind flow around a row of three square-plan tall buildings closely arranged in a row. Increase in wind load on the upwind building is observed when wind blows to the row at 30. CFD results show that the interference mechanism is mainly due by strong channeling of wind flow through the building gaps. This leads to highly negative pressures on building walls fa...

Accessibility regulations are federally enacted by the Americans with Disabilities Act (ADA). Design of buildings and facilities must comply with the guidelines developed by the authors of ADA. This paper discusses a hybrid approach using encoding prescriptive-based provisions and supplementing them with performance-based methods to support compliance and usability analysis for accessibility. T...

In this paper, we present an approach for the modeling of building interiors by a user who is equipped with a navigation system, which integrates MEMS IMU data processing with automatic interpretation of photos of evacuation plans. Such emergency plans for the evacuation of buildings are compulsory for public buildings in a number of countries. They consist of an approximate floor plan, the cur...

Modeling a city poses a number of problems to computer graphics. Every urban area has a transportation network that follows population and environmental influences, and often a superimposed pattern plan. The buildings appearances follow historical, aesthetic and statutory rules. To create a virtual city, a roadmap has to be designed and a large number of buildings need to be generated. We propo...

In order to carry out a successful commissioning exercise, it is important to plan the activity carefully and make sure all objectives are clear and that procedures are documented properly (Lawson, 1991; Choat, 1993). Certification programs such as LEED have helped promote commissioning and have their own particular criteria (Tseng et al., 2002). Some buildings may require formal validation pro...
