Investigating energy saving potential in a big shopping center through ventilation control
2019
Abstract This paper investigates energy saving measures for the ventilation system of large shopping centers. This kind of buildings is characterized by high yearly energy consumptions, because of the high level of operating hours and the frequent use of obsolete technologies. In the analyzed case studies, three big Do It Yourself (DIY) shops, located in Italy, are considered. Two different approaches are considered, they are aimed at reducing the annual energy consumption for the indoor air exchange of the sales area. The first considered retrofit solution consists in the installation of heat recovery exchangers, reducing the energy demand for the air thermal treatment without changing the…
Investigating Energy Saving Potential in a Big Shopping Centre through Ventilation Control
2018
This work shows an example of energy saving interventions on the ventilation system of a big shopping center. This kind of buildings is characterized by high energy consumptions, because of the high level of yearly operating hours and the use of obsolete technologies. In the case study, a big Do It Yourself (DIY) shop located in the southern part of Italy is analyzed, proposing two different approaches aimed at reducing the annual energy consumption for the indoor air exchange of the sales area. In the AS-IS scenario, a centralized HVAC plant, composed by six rooftops, is installed on the roof of sales area, working with fixed airflow value. The first retrofit solution involves the installa…
Energy Saving Optimizing the Ventilation Control in a Big Shopping Center
2018
The paper investigates the potential energy savings in the context of big shopping centers, thanks to the introduction of innovative technologies able to control the ventilation according the real requirement for comfort and health of indoor spaces. The case study analyses a big shopping center, where the ventilation is realized with a centralized air-conditioning plant, working with fixed air flows. Two solutions are proposed to reduce the energy consumption for ventilation. The first considers the installation of heat recovery exchangers, the second the introduction of a control system able to modulate the air exchange, according to the real requirements. An energetic and economic evaluat…
