OWL: An object-oriented framework for intelligent home and office applications

Abstract

The goal of OWL (Object-Oriented Workplace Laboratory) is to provide an object-oriented and component-based framework that supports the engineering of applications for the design, simulation, construction, and operation of buildings with more efficient use of building facilities. OWL is based on a software architecture using a combination of web and object technology. It offers location transparent and manufacturer independent access to a variety of facility control systems, and allows users to define ”scenes” to adapt their work environment. In this paper, we describe the requirements, system design and a conceptual prototype of the OWL framework. We discuss how the application of design patterns and component technology impacts the framework to support the maintenance of corporate sites globally distributed across the world. A conceptual prototype of OWL written in Java is operational, managing distributed facilities at the Intelligent Workplace at Carnegie Mellon University and at Technische Universität München.
