The document discusses a case study of implementing an energy management strategy for Inmobiliaria Colonial, a large real estate company in Spain. It outlines: 1) Creating an energy monitoring system across Colonial's 40 buildings to centrally track energy and water usage from over 300 metering devices. 2) The goals of achieving 20% energy cost savings per building within 2 years and 7% overall savings for the company. 3) Implementing hardware and software for real-time energy monitoring and reporting across the portfolio to identify savings opportunities and track performance. 4) PGI Engineering's methodology involved identifying monitoring points, installing infrastructure, ongoing energy management and reporting to Colonial on savings and targets.
