Optimized Building Automation and Control for The Improvement of Energy Efficiency and Climate Comfort Of Office Buildings

Abstract

The object of the examination is a typical office building of the 1990s, owned by a multinational company -Siemens- dedicated to energy awareness. The building also meets the energy efficiency category ‘A’ under the 7/2006 TNM Hungarian regulations concerning the energy performance definition of buildings. However, demand has emerged to implement additional changes to reduce energy usage whilst keeping the current climate comfort or even improving it. International experience forecasts around 30% energy saving potential due to optimization of the building automation and energy management system, and thus the interaction and collaboration between the building geometry, structures and services systems. The project has been built in the IDA ICE complex building energy simulation program. Running a one-year dynamic simulation will provide data that can be compared with the measured data of the actual building, so the model can be adjusted and validated to real data. After the calibration it is now possible to test the ideas under safe conditions, in a virtual surrounding. Once a particular vision of the model is proven to work effectively, it is possible to apply this to the real building control management as well.

Building performance simulation modeling techniques

“…Today's most accurate and developed building design supporting tools are dynamic building physics simulations with significantly better and complex modeling of real physical systems than steady state calculations [1]. There are already ongoing research studies in Hungary about the energy performance and energy optimization potential of buildings, which use this different dynamic thermal building simulation methods, coupled with building monitoring measurements [2], [3], [4], [5]. Beside general…”

Energetic Investigation and Economic Feasibility for a University Campus in Romania towards Becoming an Energy Supplier

“…Energy efficiency, climate comfort, and evaluating actual building energy consumption have been studied significantly by different feasibility studies to provide perfect building patterns [3]. Construction engineering and many of such evaluation studies were performed on university buildings / campus to give additional academic vision value of applying energy management / efficiency concepts on construction [4].…”

Comfort simulation supported sketch plan optimization of the University of Pécs, Medical School extension

“…Within the framework of the Hungarian Modern Cities Program, correlatively to the development of a new theoretical block of the Medical School (MS) of the University of Pécs (PTE) sketch plan decision support with building simulation was desired. Many studies investigate a wide range of diverse building optimization strategies with coupled simulation supported algorithms, whereas advanced investigations focus on building optimization using simulation coupled generative algorithms [1]- [8]. Case studies represent an important field among these optimization studies [9]- [15], providing useful COMFORT SIMULATION SUPPORTED SKETCH PLAN OPTIMIZATION 167 Pollack Periodica 15, 2020, 2 knowledge for building development.…”
