Tekfen Alanar Fruit Handling Facility, Manisa
The new fruit handling facility of Tekfen Alanar has been completed in Manisa. DOXA87 provided design and consultancy services for the project in close collaboration with Tekfen Engineering’s design team. The facility was designed to meet high hygiene standards and to fully comply with EHEDG guidelines. As part of Tekfen’s sustainability commitment, LEED requirements were followed to achieve the highest possible certification level. The design also incorporated a zero-waste approach and on-site renewable energy generation. The facility includes large-scale refrigerated storage areas and processing halls, which represented the most energy-intensive components of the project. The mechanical design addressed these challenges with a focus on energy efficiency and environmental performance. Key features included: An ammonia refrigeration plant with zero ODP (Ozone Depletion Potential) and zero GWP (Global Warming Potential)

Akasya Shopping Mall Energy Retrofit, Istanbul
In this prestigious shopping mall project, the DOXA87 team, in close collaboration with On Otomasyon, developed a data-driven control algorithm for Air Handling Units (AHUs) to minimise energy consumption. Selecting the right method to understand a building’s operational behaviour is critical to ensuring successful energy-efficient performance. Our team analysed occupancy data over the course of a year, alongside cooling demand and design parameters. This allowed us to develop an innovative demand-controlled ventilation strategy that reduced HVAC-related energy consumption by 74% - a significant improvement compared to the 30–40% savings typically achieved with conventional frequency inverter-based approaches. |

TANAP Compressor Stations, Turkey
The Trans Anatolian Natural Gas Pipeline Project posed numerous challenges due to its scale and complexity, including remote mountainous terrain, high seismic activity, and a cold climate. As part of the detailed design phase, DOXA87 was responsible for coordinating the HVAC system documentation and specifications for the compressor stations to ensure that subcontractors delivered a fully functional, clash-free design suitable for construction. We implemented innovative design strategies, including the use of BIM-based coordination tools, to meet the project’s demanding requirements. |

Serim Houses, Datça
This small-scale sustainable housing development consists of two houses located just outside Yaka Village on the Datça Peninsula. The project is situated on a steep hillside with views overlooking the Aegean Sea. The site’s hot and arid climate required unique considerations, particularly in terms of water management. DOXA87 carefully designed a rainwater harvesting system integrated with a deep-well installation to address water supply challenges. The design also followed local architectural practices by utilising natural ventilation strategies to minimise reliance on mechanical cooling. As part of its sustainable design philosophy, the DOXA87 team adopted a deliberately simple approach—such as incorporating a forced-draft fireplace using locally sourced biomass for winter heating. To support year-round living and future-proof the development, the design also includes provisions for solar PV installation. |

Kocaeli Light Rail, Kocaeli
In this ambitious project, Arup provided full multi-disciplinary design services—including planning, civil, geotechnical, SMEP, tunnelling, and fire engineering—for a 32 km new light rail system. Upon completion, the twin-track line will feature 23 new underground stations. The project includes bored and cut-and-cover tunnels, as well as mined, cut-and-cover, and above-ground stations. The MEP design scope includes the development of a specialist tunnel ventilation strategy. As part of the Arup design team, Utku Başyazıcı served as the lead MEP engineer, responsible for both station mechanical design and tunnel ventilation systems, working in close collaboration with Arup’s tunnel ventilation experts |

Çiftçi Towers, Istanbul
This mixed-use development was designed by John McAslan, Tunca, and Mixity. Arup served as the prime consultant, providing project management, full design, and executive architecture services. The project includes two residential towers, with the lower floors of one tower accommodating office space, retail units, and underground car parking. Utku Başyazıcı was the lead MEP engineer on the Arup design team throughout all design and tender stages. The building features cutting-edge and sustainable mechanical design solutions, including low-noise, multi-room EC fan coil units; greywater and rainwater reclamation systems; and a high-efficiency chiller plant with screw and centrifugal chillers. |

Akasya Acıbadem, Istanbul
Facade wind load analysis services were provided for a mixed-use development that includes high-rise towers. CFD analyses were conducted to assess how the façade systems and buildings respond to wind at various speeds and directions. Detailed modelling was performed to accurately determine façade design pressures for all critical structures. In addition, the CFD team carried out a comprehensive wind environment study to ensure adequate wind comfort across all accessible areas within and around the development site. |

THY HABOM Heavy Maintenance Hangar, Istanbul
The project comprised a nine-bay narrow-body aircraft hangar, a twin-bay wide-body aircraft hangar, a wide-body paint hangar, 120,000 m² of annex workshops, a 500-space multi-storey car park, welfare facilities, security installations, and a 5,000 m² headquarters building. As part of the Arup MEP team, Utku Başyazıcı served as the lead consultant responsible for HVAC system planning and scheme design for this new maintenance, repair, and overhaul (MRO) campus. |
