In WP1, Processes and Requirements and Use Cases screening related to the integration and optimisation of server rooms within the operational context of tertiary buildings have been extracted. The Bovisa Campus (Pilot project) Use Cases have been defined, including energy and data audit and case studies implementing energy conservation measures. Methodologies for SIMBots creation, monitoring and validation, consisting in a set of development guidelines, and for predicting and optimizing building performance using Software in the Loop, have been defined
In WP2, communication protocols and interoperability requirements necessary for seamless integration of Building Control Systems (BCS) in advanced IT server room environments have been analysed and defined. The ICT architecture of the Building Digital Twin Environment has been developed, including simulation tools, BIM representations of the server room and the cooling equipment, monitoring of real-time data, and using Software in the Loop -based Model Predicting Control algorithm. The architecture for the alpha testing of the software solutions has been also developed.
In WP3, a methodology to guide interventions in thermal management optimization of server rooms, including the definition of performance metrics, area of interventions, type of intervention, impact assessment on performance metrics, and monitoring requirements to verify and maintain energy performance during system operation through Digital Twin solutions, have been defined. Moreover, schematics for the integration of Server Rooms waste heat recovery in buildings and district heating networks have been produced, along with a simulation model for fast assessment of related energy, economic and financial benefits. A basic library of simulation components consisting of generic SIMBOTS for IT Server Room has been developed, along with the strategy to assess future scenarios using simulation models under the Building Digital Twin Environment.
In WP4, a numerical model of the innovative rack-integrated adsorption chiller was developed and implemented in the commercial software Dymola (Modelica). The proof-of-concept (PoC) of the rack-integrated adsorption chiller (RIAC) has been manufactured, and preliminary experimental activities have been carried out.
In WP5, the digital twin platform as a service has been deployed for the Bovisa Campus pilot site. The platform has connected existing devices for control and monitoring by using a VPN connection. Additionally, the design and bill of quantities for the renovation of the Campus server room have been completed, which includes waste heat recovery in the associated university building through a dedicated heat pump. Tender documentation has been prepared, and the tender has been awarded, allowing construction works to commence.
