Energy-intensive building

GAP Energy Efficiency Incubation Center, which was renovated according to EnerPHit standards and is used as an office by the EE Audit Companies in Gaziantep. It is set up in a building provided by Gaziantep Chamber of Industry, built in 1970s and located in Gaziantep Organized Industrial Zone. The project is funded fully by the Government of Turkey, and implemented within the technical cooperation project; Utilization of Renewable Energy Resources and Increasing Energy Efficiency in Southeast Anatolia Region (PHASE 2) by Southeastren Anatolia Regional Development Administration (GAP RDA) and United Nations Development Program (UNDP). The EE Incubator building is the first renovated building with the EnerPHit certification in Turkey.

GAP Energy Efficiency and Consultant Incubation Center is a pilot project and a good example in energy-efficient renovation. It provided lots of information to the Government that helped in the development of the ''Energy Efficiency in Public Buildings’’ projects going on.

The planned EnerPHit design delivers a reduction of the space heating demand by 87% and a reduction of the overall demand of delivered energy by 75%.Cost €: 174,000
Construction Period: 4 Months

Owner approach of sustainability

This pilot project sets an example for energy-efficient renovation in the region. It provided lots of information to the Government that helped in the development of the ''Energy Efficiency in Public Buildings’’ projects going on.

The building was opened with a ceremony, with the participation of former Minister of Development (Turkey) Cevdet Yilmaz, the Director of the United Nations Development Programme Helen Clark, and the Fatma Sahin, the mayor of Gaziantep City.

Architectural description

Constructed in the 1970s, hollow brick masonry building had no insulation in the outer shell (exterior wall: U= 2,70 W/m2K, roof: 1,60 W/m2K, windows: 2,50 W/m2K). It has only one level with a floor area about 250m2 separated into 3 wings (parts) is being used as an office space. The south side of the building is surrounded by dense pine trees with an average height of 8m, which are an asset for design in regards to solar shading. Also the building has a compact form therefore it is a great advantage towards achieving the EnerPHit standard. However the building was in such a bad condition; due to moisture there were heavy molds and irreversible disorders like saltpeter on the interior walls. Consequently, insulation in combination with good ventilation and air tightness brought the building sustainability, which avoids all the nuisances.

Energy consumption

Primary energy need : 79,00 kWhpe/m².year

Calculation method : Other

Breakdown for energy consumption :

Primary energy consumption is calculated according to PHPP
Annual heating demand 20 kWh /(m2a )
Heating load 19 W/m2

Envelope performance

More information :

-Super insulated building fabric with (walls and roof: 200 mm rockwool – 0,033 w/mK, ground floor and foundation wall: 200mm XPS, 0,035 w/mK). A building envelope with minimized thermal bridges and air leakage.

Airtightness Test Result: Before Renovation 9 ach50 - After Renovation 1 ach50

- Triple Glazed, Low -E insulated frame windows with U value: 0.81 W/(m 2K) were installed

Systems

- Besides energy efficiency the building with thermal insulation, air tightness and ventilation guaranteed new and healthy air, without any risk of disease related to non-controlled ambient moisture. Also insulation in combination with good ventilation and air tightness brought a building sustainability, which avoids all the nuisances such as; moisture that generates molds and irreversible disorders like saltpeter, which was observed on the existing interior walls before the renovation.

-The ventilation system was designed with steel ductwork and highlu energy efficient MVHR unit (heat recovery efficiency: 75%)

-Heating and cooling was performed by using radiant floor heating/cooling system which activated by air sourced heat pump.

- Solar panel system was placed on the roof to meet hot water demand.
