Building boundary lines are important spatial features that characterize the topographic maps and three-dimensional (3D) city models. Airborne LiDAR Point clouds provide adequate 3D spatial information for building boundary mapping. However, information of boundary features contained in point clouds is implicit. This study focuses on developing an automatic algorithm of building boundary line e...

The effects of building leakage on heat and mass transfer in buildings are difficult to model due to the difficulty in knowing crack size, shape, position, and number. Nevertheless, interest remains high in the estimation of crack areas in buildings because of the important effects cracks have on infiltration, indoor air quality, building energy performance, and because of interest in exploring...

The location of the author of a social media message is not invariably the same as the location that the author writes about in the message. In applications that mine these messages for information such as tracking news, political events or responding to disasters, it is the geographic content of the message rather than the location of the author that is important. To this end, we present a met...

In this paper, we describe the evaluation of a method for building detection by the Dempster–Shafer fusion of airborne laser scanner (ALS) data and multi-spectral images. For this purpose, ground truth was digitised for two test sites with quite different characteristics. Using these data sets, the heuristic models for the probability mass assignments are validated and improved, and rules for t...

An overview of development of high-rise buildings is presented. Key advancements leading to highrise buildings of today are discussed. Structural analysis and design considerations for modern highrise buildings are presented and trends in design of tall buildings of the future are discussed.

In this paper, we describe an automated technique for estimating power consumption by computers in buildings by processing visual imagery collected during a walkthrough of the building. This is an important problem since desktop and laptops are the largest contributors to electricity consumption in most large commercial buildings. The images used for estimation are obtained by a backpack equipp...

BACKGROUND The study investigated the perspective of people with mobility limitations (PWML) in Zambia, firstly of their accessibility to public buildings and spaces, and secondly of how their capacity to participate in a preferred lifestyle has been affected. OBJECTIVES Firstly to provide insight into the participation experiences of PWML in the social, cultural, economic, political and civi...

Indoor air quality (IAQ) in a building is a very important element to ensure the health and comfort level of the building occupants. This is because work productivity may be interrupted due to the polluted environmental condition and bad indoor air quality. Both factors may lead to bad health and physical condition and consequently to bad work performance. The study presents the understanding a...

OBJECTIVES Sick building syndrome (SBS) is described as a group of symptoms attributed to the physical environment of specific buildings. Isolating particular environmental features responsible for the symptoms has proved difficult. This study explores the role and significance of the physical and psychosocial work environment in explaining SBS. METHODS Cross sectional data on the physical en...

indoor environment. The most important include indoor pollutants, outdoor pollutants near the building, pollution transport through the ventilation system, air cleaning or filtration, and indoor climate (temperature and relative humidity). Many building materials, the furnishings and equipment, and the occupants and their activities are sources of indoor pollution. Following is a list of some o...
