Methodology for the design of energy production and storage systems in buildings: Minimization of the energy impact on the electricity grid

Abstract

human life requires energy. Moreover, people spend around 90% of their time in buildings while about 40% of primary energy needs are due to buildings. That is why the present paper deals with a methodology allowing identifying and assessing the energy impact of a building on the electricity grid. Thanks to both the building models we developed and fuzzy logic contribution (used to control ventilation and develop occupancy scenarios related to human habits and lifestyle), the results we obtained in simulation validate the proposed impact indicator. Different insulation levels were considered as well as energy production (solar photovoltaic and thermal panels and a vertical axis windmill) and storage (a domestic hot water tank) systems. These results highlighted the pertinence of such an indicator for optimizing the design of the just-mentioned systems and minimizing the amount of energy exchanged by buildings and the electricity grid. One can promote energy injection or take into account the status of the electricity grid when designing these systems. As a key result, the produced renewable energy is partially self-consumed, what allows for a more efficient and rational use of energy in buildings.

Parametric study of ice thermal storage system with thin layer ring by Taguchi method

“…Nowadays, ice thermal storage (ITS) system with a standard chiller has been widely used to store energy during off-peak hours and release energy during on-peak hours in order to not only reduce energy consumption but also the demand charges during peak hours [1], since thermal conditioning systems such as AC and other refrigeration systems take a share of 16~50% of the energy consumption among all the energy used in the building sector [2], while people spend around 90% of their time in buildings [3]. Using thermal storage system is a cycling process for energy transfer and conservation and provides a comfortable environment for people.…”

A strategic decision support system framework for energy-efficient technology investments

“…Random time horizons are analyzed in relation to stopping time moments in catastrophic risk management by Ermoliev et al (2010). Only recent papers tackle systems planning at the building level (Salvador and Grieu 2012;Kumbaroglu and Madlener 2011).…”
