6 FAQs about [Office building energy storage device]

Do office buildings save energy?

Again, savings are influenced strongly by the occupancy rate. Free cooling in office buildings can save up to 8% in chiller energy but strongly depends on climate. In the case of lighting systems, the reference in literature is typically a class D system where the lighting is mostly enabled during office hours.

How can a building management system save energy?

This includes correcting extreme values of set points, controlling the interlock between heating and cooling and alarming and monitoring functions. Although this is a key part of a Building Management System, this is only discussed shortly as it does not always lead directly to energy savings.

Can smart outlets save energy?

It is worth noting that plug loads are a significant source of electricity consumption in offices, i.e. up to 20% of office electricity use and likely more in energy-efficient office buildings, the control of these loads through smart outlets can lead to energy savings [60, , , , ].

Does DCV save energy in an office building?

The office building may have high relative energy savings, but the cost savings are limited due to the installed ground source heat-pump and energy recovery ventilation system. Implementing DCV also greatly affects the energy consumption of fans. Chenari et al. also studied the implementation of DCV in an office building .

How does occupancy rate affect energy performance of office buildings?

The occupancy rate is widely recognized as a crucial factor in determining the energy performance of office buildings, particularly when considering the implementation of BACS. The ability of BACS to effectively align energy supply with the actual energy demand is most pronounced in cases where the occupancy rate is reduced.

Does occupancy based lighting control save energy?

The control method based on occupancy information sets the airflow to zero in unoccupied private offices and conference rooms, resulting in energy savings of 13% in the Baltimore climate. However, savings were partly due to occupancy-based lighting control.
