Wide spread usage of GSM and On the coast of Aegean Sea Unfair foreign interferences forced Turkish firms to create innovative solutions. A no mans’ island was chosen to build a reflector unit. Design is based on a stone cube building shaded by a big panel consisted of 12 PV units to natural cooling.

On summers PV’s in winters wind turbine supplied required energy by the GSM Reflector unit. This combination and harmony of the building to nature consisted a beautiful combination.

The importance of renewable energies is considered by using solar and wind power. The social cost concept is also important in this building, which is usually ignored in energy investments. The special position of renewable energy sources for Turkey is focused on.

Adobe House in Hasandede — Hocamkoy Project

The aim ofthe project is to support and manage the implementation ofthe ‘Ecological — Village model’ in Turkey. This implementation will be a demonstration action focused on the first Turkish application of its kind, near Hasandede village, 90 km from the capital city Ankara. As a reproducible life model it will help building an eco-centric future. Through this ‘Eco-Village model’, a new sustainable life with architectural, agricultural, social, cultural and energy aspects will be designed. The aim is to bring the established village of Hasandede and the projected eco-village of Hocamkoy to form a true model of ecological sustainability in rural Anatolia. Based on the outcomes, new applications will be initiated around the country.

The housing problems of Hocamkoy project will be considered based on ecological aspects. Principles used in the design of area and houses and other common buildings can be summarized as follows;

• Use of architectural characteristics of the vernacular architecture in the region,

• Use ofthe natural building materials

• Importance of the renewable energy sources; use of active and passive solar energy,

• Wind energy and biomass,

• Harvesting waterfrom nature and re-using,

• Composting and recycling domestic wastes,

• Minimization of travel and transport distances.

The most important characteristics of the vernacular architecture of the region are use of adobe as building material. This tradition has decreased even lost at recent years. Adobe is suitable material in respect to its high insulation value and organic structure. Adobe walls are thermal masses which collect solar energy in day time and transfer it indoors space at nighttime.

Energy need of the buildings can be provided by passive and active utilization of solar energy. Buildings will be oriented to the south or south — east which are optimum orientations for space heating in this region. The topography and inclinations of the land are suitable in order to gain more radiation to the buildings. The ratio of the volume to surface will be designed for maximum energy gains and minimum energy losses. Spatial organization and architectural form are firmly interconnected with such factors as solar control, ventilation, insulation, location of (thermal) walls, surface properties, and color. Principles for creating sustainable buildings have been established for some time. Solar collectors will supply domestic hot water and space heating. Solar cells can provide electricity need of the buildings. Wind speed of 5-7 m/s can be used to supply up to 1 kW of energy with a wind turbine having a diameter of 1.5-2.5 m. A Savonius rotor type windmill can be installed in the vicinity of the building, which may be attracting due to its easy construction and noise-free operation.

The climate of the Central Anatolian region is excellent to built a self-sufficient house. A very small amount of space heating requirements during winter months can easily be supplied by south and/or east facing direct gain windows. The small overheating problem, which might be faced during summer months, can be solved by adjustable overhang shading devices and by appropriate orientation of the building for supplying air vents with the help of the wind. A wise insulation and maybe the use of thermal mass walls for some of the rooms might be effective in solving insignificant requirements of cool nights and hot afternoons.
