Energy Conservation in an Office Building Using an Enhanced Blind System Control

Abstract

Abstract:The two spaces office module is usually considered as a representative case-study to analyse the energetic improvement in office buildings. In this kind of buildings, the use of a model predictive control (MPC) scheme for the climate system control provides energy savings over 15% in comparison to classic control policies. This paper focuses on the influence of solar radiation on the climate control of the office module under Belgian weather conditions. Considering MPC as main climate control, it proposes a novel distributed enhanced control for the blind system (BS) that takes into account part of the predictive information of the MPC. In addition to the savings that are usually achieved by MPC, it adds a potential 15% improvement in global energy use with respect to the usually proposed BS hysteresis control. Moreover, from the simulation results it can be concluded that the thermal comfort is also improved. The proposed BS scheme increases the energy use ratio between the thermally activated building system (TABS) and air-handling unit (AHU); therefore increasing the use of TABS and allowing economic savings, due to the use of more cost-effective thermal equipment.

Optimization of deterministic controls for a cooling radiant wall coupled to a PV array

“…However, this implies more complex control strategies, which are currently an important area of research. Considering examples in which the building structure was used as TES or buffer, adaptive predictive control was applied to radiant floor [23], model predictive controls were applied to radiant ceiling for heating and cooling [36] or to concrete core activation [37], cooperative fuzzy model predictive control was applied to concrete activated floor [38], and model predictive control for thermally activated systems was applied with additional integration of blinds control [39].…”

“…Existing literature report intelligent control methods, which include model predictive control (MPC), gain scheduling, optimal control, robust control, nonlinear adaptive control, fuzzy logic, genetic algorithm, etc., [32,34,35,38,[40][41][42][43][44][45][46][47][48][51][52][53][56][57][58][59][67][68][69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84]. As compared with PIDs as proposed in this study via mixing loops, they are robust and energy efficient.…”

Heuristic Optimization for Designing Centralized Air Distribution Systems in Non-Residential Buildings

“…Implementing energy-conserving applications in the building industry is crucial for energy development policies supported by the European Union to reduce energy dependency and greenhouse gas emissions [1]. In this regard, Heating, Ventilation, and Air Conditioning (HVAC) account for a significant proportion, where the share of ventilation is 10-50% of buildings' electricity use [2].…”
