Energy-intensive building

GAP Energy Efficiency Incubation Center 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 the 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 Southeastern Anatolia Regional Development Administration (GAP RDA) and United Nations Development Program (UNDP). This 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 of 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

Envelope performance

Envelope U-Value : 0,10 W.m^-2.K^-1

More information :

- Super-insulated building fabric (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

Heating system :

Heat pump

Heat pump

Other information on HVAC :

- Besides energy efficiency the building with thermal insulation, airtightness 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 airtightness brought the 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 highly energy-efficient MVHR unit (heat recovery efficiency: 75%)

-Heating and cooling was performed by using a radiant floor heating/cooling system activated by an air sourced heat pump.
- Solar panel system was placed on the roof to meet hot water demand.
