Antwork Elcire Building

Antwork Elcire Building was formerly an abandoned facility which was renovated into a new co-working facility. Antwork provides workspaces formed by a technology-enabled ecosystem that cultivates innovation, collaboration and productivity.


While achieving its goal by creating this active modern workplace, Antwork aims to present energy efficient solutions to reduce energy consumption. These energy savings will add a green image to the facility and result in cost savings for its clients. The proposed measures are LED lighting, a VRF system, and PV plant.
