Abstract

Building automation integrates the active components in a building and, thus, has to connect components of different industries. The goal is to provide reliable and efficient operation. This paper describes how simulation can support building automation and how the deployment process of simulation assisted building control systems can be structured. We look at the process as a whole and map it to a set of formally described workflows that can partly be automated. A workbench environment supports the process execution by means of improved planning, collaboration and deployment. This framework allows integration of existing tools, as well as manual tasks, and is, therefore, many more intricate than regular software deployment tools. The complex environment of building commissioning requires expertise in different domains, especially lighting, heating, ventilation, air conditioning, measurement and control technology, as well as energy efficiency; therefore, we present a framework for building commissioning and describe a deployment process that is capable of supporting the various phases of this approach.

Highlights

  • Buildings are evolving from containers that provide a safe and comfortable environment for the tenant into active participants of a smart infrastructure, where they pursue multi-objective goals in controlling their internal processes

  • The task of introducing a structured description and process into the interdisciplinary field of building commissioning is challenging in different regards: first, building construction and especially commissioning of the building automation system is subject to volatile goals that may change at various stages throughout the process

  • Once the data acquired in the different steps is accessible (e.g., status on design brief acquisition, commissioning data, heating, ventilation and air conditioning (HVAC) system information, comparison of thermal simulation opposed to real monitoring data, etc.) it is a strong support for a human integrator to make checks of completeness, consistency, and correctness, and implement proper change management

Summary

Introduction

Buildings are evolving from containers that provide a safe and comfortable environment for the tenant into active participants of a smart infrastructure, where they pursue multi-objective goals in controlling their internal processes. Optimization of costs and energy efficiency, remote maintenance of building portfolios, migration of intelligence from in-house hardware to external data centers and the role of smart buildings in a smart city are all upcoming developments in building automation It is, necessary to prepare building automation systems by taking a look at the organization of deployment and operation of the BMS and improving these processes to make buildings ready for the step. It is important to have continuous energy management complemented by the implementation of energy and cost saving strategies This can be provided by a Simulation-assisted Building Control (SaBC) service.
