Energy Conservation during Unoccupied Hours

Hi,

I'm using Openstudio to implement energy conservation measures to my building model. The building is actually an advanced one which has room occupancy sensors and also a building management software for the equipment. It has an absorption chiller for cold water supply and a boiler for hot water supply to the AHUs and FCUs installed.

The building is actually consuming half of its energy during occupancy hours (From 8 am till 8 pm) and half of its energy during un-occupancy hours (8 pm till 8 am).

I'm modeling some energy measures that I could think of which are: Replacing double glazed windows with triple glazed ones, lightning replacements to decrease lighting loads, reducing electric equipment loads at night, modifying HVAC setpoints during un-occupancy, and even turning the HVAC system off during un-occupancy.

The roof insulation is properly structured, so no need to modify anything to it. The installed pumps are all Variable Speed pumps.

I'd like to take your thoughts on any other measures you can think of.

Thanks.
