“…Nagarathinam et al [148] investigated the spatial variations in temperature and occupancy on the HVAC system operation in open-plan offices. They used MPC to find the optimum temperature set point, which is later used in a proportional-integral-derivative (PID) controller to adjust the fan speed of the HVAC system with multiple AHUs.…”

“…Previous studies addressed open-plan offices primarily from sociological and psychosocial perspectives, [2][3][4][5][6][7][8] with a few of them dealing with the indoor environmental performance. 9,[20][21][22][23] Nevertheless, IEQ aspects affect open-plan office employees' health, comfort and productivity. 9 The design of the open-plan office is an early design task; hence, a method of assessing the effects of multiple design parameters on predetermined performance objectives and determining optimal factor level combinations can enhance informed decision-making.…”

The hybrid philosophy behind the mixed-mode (MM) strategy aims at achieving energy-efficient buildings and sustainable development. A performance-based open-plan office design facilitates the handling of multiple design parameters to identify optimal design solutions for effective MM offices. This research presents a method of open-plan office design for an improved natural ventilation potential and reduced supplementary heating/cooling loads in the early design stage within a Mediterranean climate. Different design variables including office size, layout aspect ratio, window orientation and fraction of window opening, with several factor levels, were studied. The design of experiment developed by the Taguchi method was applied to define the most informative simulation scenarios. Analysis of variance was utilised to indicate the effectiveness of each design parameter, while the signal-to-noise ratio approach identified the near-optimal level combinations that support informed decision-making. Suggested by the EN 15251:2007 standard, the hourly dynamic simulations were conducted using TAS Engineering. The measurement criteria included airflow rate, carbon dioxide (CO2) levels, adaptive thermal comfort and air-conditioning (AC) loads. The calculated indicator was the number of hours in which a specific performance criterion is met during the occupancy period and the AC loads.

Modeling, Simulation, and Temperature Control of a Thermal Zone with Sliding Modes Strategy

et al. 2019

View full text Add to dashboard Cite

To reduce the energy consumption in buildings is necessary to analyze individual rooms and thermal zones, studying mathematical models and applying new control techniques. In this paper, the design, simulation and experimental evaluation of a sliding mode controller for regulating internal temperature in a thermal zone is presented. We propose an experiment with small physical dimensions, consisting of a closed wooden box with heat internal sources to stimulate temperature gradients through operating and shut down cycles.
