Geothermal district cooling in Limassol
Overview
Limassol, located along the sun-kissed southern coast of Cyprus, represents a gem of history and modernity. Limassol stands as the island's second largest urban hub, pulsating with life and culture.
The Limassol Marina, once a neglected corner of the city, now hosts the "Castle Residences", an exclusive complex comprising 66 luxurious apartments. Inaugurated in 2021, the "Castle Residences" stand as a testament to architectural innovation, luxury living and eco-conscious living in Cyprus. Through an innovative open loop decentralized geothermal system and meticulous management, the project stands as an example of environmental stewardship and energy conservation.
Indeed, the integration of this cutting-edge energy solution not only underscores the commitment to reducing carbon footprint but also testify a new era of sustainable development in Limassol. As the largest energy integration and saving initiative of its kind on the island, the "Castle Residences" exemplify the harmonious coexistence of luxury and environmental responsibility.
Investment history
The Limassol Marina project started in 2010 with the aim of enhancing Limassol's maritime tourism infrastructure and offerings. Despite the ambitious vision, the project faced significant hurdles during its inception. Plans were initially submitted in 2008, yet obtaining the requisite licenses proved to be a protracted process, spanning two years. Surprisingly, navigating the bureaucratic maze to secure permits eclipsed even the challenges of constructing complex developments, including those on artificial islands within the water. Originally budgeted at €300 million, the construction costs for the "Castle Residences" surged to €400 million upon completion. Notably, Limassol Marina Ltd entrusted Yfantis Engineering consulting office with the innovative geothermal system project, designed to fulfill the complex's cooling, heating, and domestic hot water needs. SYCHEM CYPRUS LTD assumed the mantle for the central facilities' construction, geothermal engine room establishment, commissioning, and integration into a central Building Management System (BMS) for optimal energy efficiency. Since its inauguration in January 2021, the combined open-loop decentralized geothermal and management system of the "Castle Residence" has been operating seamlessly, marking a milestone in sustainable living.
Technical details
The heating and cooling infrastructure implemented within the residential complex consists of an electromechanical system integrating air conditioning and domestic hot water production, leveraging an innovative approach that combines geothermal technology with heat recovery mechanisms. With a total cooling capacity of 1,120 kW, the decentralized geothermal loop system ensures optimal performance and sustainability. Each apartment is equipped with a dedicated mechanical cupboard housing an autonomous water-cooled heat pump, meticulously designed to cater to individual energy requirements. Through seamless integration with the central geothermal system and smart operational algorithms, maximum energy efficiency is guaranteed, offering multiple benefits such as aesthetic appeal and the elimination of outdoor air conditioning units. Furthermore, the absence of an engine floor not only streamlines HVAC installation but also prolongs the lifespan of heat pumps and mechanical equipment by shielding them from environmental factors like salty sea air. Operation and control of the system are facilitated through a sophisticated Building Management System (BMS), featuring a user-friendly graphical interface, remote accessibility, energy analysis capabilities, and comprehensive parameter recording functionalities.
