With the arrival of Dario Dell’Agnello and his team at Great Synergy, Great Estate customers will have technical support for the plant engineering design of their prestigious properties.
WHO IS DAG SRL

In the Italian plant engineering landscape, DAG S.r.l. is now a structured and innovative company, the result of the vision and experience of engineer Dario Dell’Agnello. The company’s professional journey began in 2009, the year Studio Dell’Agnello was founded, initially focusing on the design of electrical systems and software development for industrial machines intended for international markets.
Over time, the firm has gradually expanded its expertise and services, specialising in HVAC system design, photovoltaic system installation and energy certification. A fundamental step forward was taken in 2022, when the company entered the world of BIM and implemented Revit MEP design, now one of its main strengths.
In addition to its design activities, DAG S.r.l. can, upon request, offer contracting services for plant installations, which is particularly useful for complex or unfinished construction sites.
Technical support for buyers and owners of prestigious properties
The core business of DAG S.r.l. remains plant design, but over time, the company has developed a range of complementary services that provide concrete support to Great Estate’s clients. Among these, the following play a central role:
- Plant engineering assessment reports on properties, available in both Italian and English – a fundamental plus for international customers.
- Energy consulting, useful for optimising consumption, performance and management costs;
- Analysis and technical interventions to resolve specific issues within residential and luxury properties.
These are high-value-added services that allow buyers, owners and investors to have a clear and reliable view of the state of the systems, facilitating informed decisions and targeted interventions to improve the property.
A professional relationship established in 2010
The collaboration between DAG S.r.l. and Great Estate began in 2010, initially focused on energy certification, was interrupted for a few years, and was officially resumed this year. A positive professional experience that has allowed us to establish a relationship based on reliability, competence and availability.
