...Rehan Khalid; Aaron P. Wemhoff; Mai Khuc; Ajay J. Nayar; Steven Schon A thermo-economic analysis (TEA) of a novel cooling and enhanced heat recovery (CEHR) system for data centers (DCs) is presented. Three financial metrics (net present value—NPV, return on investment—ROI, and payback period—PP...

... in terms of minimization of primary energy consumption and environmental emissions. Simulations showed that thermal insulation has a higher impact on winter heating and slightly affects the summer cooling requirement. In Milan, the refurbishment gains relevance as the energy and carbon payback periods...
