Enel X and Euro add third energy efficiency project in multifamily buildings

• Water heating by heat pumps is generating energy savings of up to 49 % on average to date and reducing CO2e emissions by more than 107 tons per year.

Santiago, March 14, 2025—The west and east towers of the Portal San Diego building, located in the Santiago district, have undergone modernization and enhancement of their two thermal power plants. This improvement is the result of a collaboration between Euro and Enel X, which installed two 40 kW aerothermal heat pumps. These upgrades will provide the residents of the 358 apartments with sustainable access to hot water. This is the third project of its kind executed by the two companies.

The optimization (retrofit) of both thermal power plants included the installation of the Heatguard control and monitoring system®. This system automates the management of the thermal power plant equipment used for generating hot water in real-time. Adjusting the parameters to meet demand significantly enhances the process's efficiency.

This project's implementation provides substantial benefits to residents and significantly enhances efficiency, achieving average energy savings of up to 49% so far. Advanced technology prevents the emission of over 107 tons of CO2 equivalent each year, which is comparable to the amount absorbed by 5,956 trees annually. Claudio Candia, Government Manager at Enel X Industries, highlighted Euro's initiative, emphasizing that "innovative solutions, like those implemented in the multifamily building on San Diego Street, offer an attractive alternative for real estate companies. These solutions help lower costs, improve the efficiency of water heating processes, and contribute to reducing emissions from polluting sources. This project is the third with similar characteristics that we have carried out together with Euro, which demonstrates the benefits that this type of optimization brings to the community.

The work being done in the Portal San Diego building is based on the Heating as a Service (HaaS) business model. In this model, Enel X is responsible for designing and implementing the project and providing preventive maintenance for the thermal power plants. Euro only pays for the heating service based on the volume of hot water supplied, without any initial investment in the project.

Jorge Vergara, Euro's Development and Projects Manager, stated, "We are very pleased with the modernization that Enel X has carried out in the thermal power plants of our residential rental projects, as it will allow us to offer a high level of thermal comfort to our customers through ultra-efficient and environmentally friendly systems."

One advantage of Enel X's solutions is that they measure the efficiencies and savings resulting from the implementation of systems that optimize thermal power plants. This measurement uses international protocols, specifically the IPMVP and RETScreen. These protocols provide detailed information on consumption, yields, demand periods, and other valuable data, enabling more efficient building operations.

Enel X and Euro have solidified their partnership with the launch of a robust thermal power plant at San Diego 895. This project marks their third collaboration, strengthening not only their business relationship but also their commitment to sustainability through initiatives that prioritize energy efficiency. Additionally, Euro's other multifamily buildings utilizing Enel X solutions are located in Hipódromo 1310 and Arturo Prat 1237, both situated in the Santiago city.
