In addition to the MPC(Model Predictive Control) study in estimating in advance the control applicable to actual buildings based on a model in which a simulation tool is used, a variety of studies, including temperature control, lighting control, and operation strategy, have been conducted recently. Actual buildings are controlled and operated in the integrative mode, and, therefore, the impact...

We consider two problems in the design and operation of energy-efficient buildings. The first is the prediction of energy consumption of a building from that of similar buildings in its geographical neighborhood. The second problem concerns the localization of faults in building sub-systems with a focus on faults that lead to anomalous energy consumption. For both problems, we propose algorithm...

This paper investigates the interaction between supermarket heating, ventilation and air conditioning and refrigeration systems through simulation in EnergyPlus. This interaction has been studied by modelling a generic UK supermarket. The impact on the sum of HVAC and refrigeration energy consumption due to changes in a range of operating conditions was studied. These include the effect of alte...

Parametric analysis is a powerful method for exploring alternative design options and establishing variable dependency therefore design guide. The text-based user interface of EnergyPlus makes it a perfect simulation tool for automated (or scripted) parametric analysis. Since the number of simulations required for parametric analysis tend to be large, a software utility that may take advantage ...

Radiance matrix-based methods enable efficient parametric simulations, allowing users to vary sky conditions, fenestration systems, and other model parameters at a minimal cost computation. However, the steep learning curve complex workflow hinder widespread adoption of methods. The frads Python library with series command-line tools was developed automate entire simulation process, lowering en...

As high performance design is becoming more desirable in the field of architecture, the need for supporting architects with environmental analysis tools is also growing. Rhino/Grasshopper is one of the most widely used platforms that are used by designers today. There are already a number of environmental plugins developed for Rhino/Grasshopper. However, Ladybug offers several advantages that a...

This paper proposes and demonstrates the effectiveness of an economic model predictive control (MPC) technique in reducing energy and demand costs for building heating, ventilating, and air conditioning (HVAC) systems. A simulated multi-zone commercial building equipped with of variable air volume (VAV) cooling system is built in Energyplus. With the introduced Building Controls Virtual Test Be...
