SME construction company DMS Yapi, from Istanbul, deals with the replacement of old residential buildings, demolished under the Turkish Urban Transformation Plan, with new, more energy efficient, ones.

The company was reconstructing a residential building to the energy performance Class C, the minimum required by law in Türkiye.

The TuREEFF consultant convinced the company to additionally invest and upgrade the building to the EPC Class B, improving the energy performance of the building by 15 per cent in comparison to the initial design. To assist this upgrade, the TuREEFF’s engineering team provided the construction company with technical advice at every phase of project preparation and implementation.

The company applied for the TuREEFF loan of TL 500,000 to implement the additional suggested measures, including new thermal insulation, a higher energy efficiency class boiler and others.

The project, in Istanbul’s Kadıkoy district, is to be completed in 2016, leading to 60% energy savings and 65% CO2 emissions decrease as compared to the initial building design. The future tenants will immediately feel the financial benefits of the energy efficiency measures implemented after receiving their lower energy bills. Equally they will enjoy improved comfort.

TuREEFF supported the construction company with advisory assistance, as well as the bank with marketing and PR activities by organising awareness raising campaigns and promotional activities on the benefits of higher energy efficiency residential buildings in the Turkish market.

The construction company’s owner, Mr Berker Ozağac, said that unlike other commercial loans, the TuREEFF loan added real value to his business by providing an independent evaluation of investment measures and by developing the competence of the company’s staff in energy efficiency.

This support was provided thanks to the donors, the European Union Instrument for Pre-Accession Assistance (EU IPA) for Turkey and the Clean Technology Fund (CTF).

Construction companies using the TuREEFF Reconstruction Loans contribute to a reduction of CO2 emissions by offering their clients more energy efficient homes with lower heating and cooling expenses.
