Odayeri Ecopark Project

Odayeri, which is affiliated with Eyüpsultan Municipality, is a village within the borders of Istanbul, bordering the northern forests that still maintain its rural character. Upon the request of the Municipality, an Ecopark was designed to have different economic and ecological outcomes.

The goal of the project:

To revitalize the soil in the village's old pasture area, which has lost its productivity.
Increasing biodiversity through permaculture practices.
Creating controlled pastures and wetlands for animals.
To facilitate access to clean food for both villagers and those coming from outside the village, with community gardens, market areas and ecocafes where permaculture practices will be practiced.
To assist development by supporting villagers in the production of value-added, healthy products.
To raise awareness of city people on natural life, climate change, permaculture and clean food.

Land Survey and Analyzes:

The land was observed on site in an area of 50 decares, the soil structure was examined and the necessary laboratory tests were performed.
By examining the vegetation, information about local species was collected.
By using drone flight and technological infrastructure, a 3D model of the land was obtained and analyzes were made through programs.

Data collecting

In order to identify the soil structure, inspection pits were opened at 5 points in the field and soil samples were taken.

3D Model

Photos taken during drone flights over land are converted into 3D models in 'Context Capture' software. Various examinations and measurements can be made on this model.

Slice Analyzes

With slice analysis, which is a part of permaculture design, the potential of the land, threats and opportunities are investigated. Possibilities of benefiting from solar energy with the sun zone on the south-facing land are examined.

Slice Analyzes

Winter and summer winds coming to the land are investigated and a benefit/harm analysis is made.

District Design

In 'zone design', one of the permaculture design stages, operations are planned in different parts of the land.

Topographic Map

In the resulting 3D model, objects on the ground (trees, buildings, etc.) are cleaned and contours / contours of the soil level - topographic map are produced. Preliminary project work will be carried out on this map.

Permaculture Design Site Plan

With permaculture design, the locations and functioning of all components that will be located on the land are shown.

Earthworks

SiteOPS software is used for field earthworks.

Earthworks

In earthworks to be carried out on the field, excavation and filling areas and work volume can be calculated.

Approach to the Project:

The areas were determined in line with the land survey, needs program and analysis results.

As a basic approach, it is divided into two different parts.

In the designed area, Zones 0, 1 and 2 , which are the upper side of the main road axis, include social areas, education and workshop areas and community gardens. Zones 3 and 4 , located at the bottom of the road, include practices to revitalize the soil such as pastures, water ponds, and food forests.

In District 5 , the natural forest texture was preserved and suggested as areas where visitors could observe the forest layers formed in the natural process.

District Settlement

Concept Layout Plan

Preliminary Project (November-December 2020):

After the permaculture design was completed, a preliminary project study was carried out. In the preliminary project, the design and positioning of ecological structures, access lines, and detailed designs of the gardens were carried out.

Earthworks, December 2020

After the acceptance of the preliminary project, while the detail and application projects of the superstructure and infrastructure were being prepared, soil studies were carried out in the natural pasture area in the south.

Ecopark Layout Plan

Ecopark Center: Ecological structures, access roads, gardens

Ecopark 3-D Model

The components of the designed project (structure, road, terrace, pond, planting) are added to the existing landscape.

Ecopark Buildings

Central area where ecocafé, activity center and marketplace structures are located

View from the South

Ecocafe & Square

Guests will enjoy nature and natural food in the square in front of the ecocafe, which has a gourmet menu of seasonal natural products.

From the Ecopark Entrance to the Square

Visitors reach the ecopark center immediately from the ecopark entrance.

ecocafe

It was designed with passive solar principles and natural building materials.

Square

There is an ecocafe on the left of the square and a marketplace area on the right.

Ecostructures with passive solar design

By using solar energy effectively, we significantly reduce heating and cooling costs.

On December 21:

In winter, the south is horizontal and lots of rays enter through the glass in the south of the ecocafe, warming the soil wall in front, and the interior of the building is also heated with this heat mass.

On June 21:

In summer the sun is high. Shading by deciduous trees is used in the south to prevent direct sunlight from entering the building. Roof slopes are also adjusted to prevent sunlight from entering.

Observation terrace

An observation terrace overlooking the pasture to the south of the ecopark center was considered.

Pasture & Food Forest

The sloping land in the south was designed as a natural habitat for buffalos, cows, chickens and ducks.

Activity Center & Community Garden

Training and workshops to provide knowledge, skills and experience will be organized at the activity center. Various gardening activities will be carried out in the community garden right next to it.

gardens

There will be various garden examples within the ecopark: deep/high plant beds, medicinal plants, endemic plants...

Greenhouse

The community garden also includes a geodesic greenhouse

Hügelculture Garden

We also have a fertile natural garden application area in the soil on wood logs stacked in the soil.

Food Forest on Terraces

The terraces that divide the pasture into parcels serve as travel and access paths, retain rainwater and create a food forest containing various forests, nuts, fruit trees, shrubs and medicinal plants.

Terrace Section

Strolling the Terraces

Visitors will observe nature and its abundance while wandering around the ecopark.

Earthworks Application

After the terrace lines and pond areas are marked on the land, earthworks are carried out with construction equipment.

Hügelkultur on the terrace

There are wood logs and branches in the mounds in the south of the terraces.

View from the North

Terraces are opened, branches/wood are stacked for hügelculture on the lower terrace levels.

Bird's Eye View

After the ponds and terraces are prepared, mulch (ground branches) is spread on the soil.

Mulching Work

With a 10-15 cm thick mulch layer, the clay soil is loosened by increasing the amount of organic matter, so that pasture grasses can root deeper.

Afforestation on mounds

Trees in the Food Forest were planted on the Hügelkül mounds.

terraces

The mound, the planting and the path on the terrace.

Insemination

Grass seeds that will form the pasture are sprinkled on the mulch.

Mulch Covered Pasture

While the mulch layer enriches the soil, it also provides an environment for the seeds planted on it to emerge and root.

After Rain and Snow

Terraces opened in the contours create obstacles to water flow, and water accumulates there and is absorbed into the soil. After the rains, water started to accumulate in the ponds.

Catchment

Water retention started in terraces and ponds. We can store water in natural ponds opened in clay soil.

Sprouting

Pasture grasses sprouting in the mulch layer (January 21, 2021)

Soil structure:

At the first observation, it was determined that the topsoil was very dense and the clay content was very high up to a depth of 30 cm. From the inspection pits opened, it was seen that the clay layer continued into the depths.

Natural Pastures and Food Forest Application at Lower Elevations:

During the establishment phase of the ecopark, we recommend that the natural pastures and food forest installation works at the lower elevations be completed in December 2020. (Since it is tree planting season)

To perform the applications in the image

For the soil improvement and pasture creation study in the open area between the ditches in the Lower Land, samples were taken and analyzed from this area with dense soil, seen below.

- Factors such as pH, conductivity, salt content, water saturation, lime, sand, clay and silt were analyzed.

Gray Water Harvesting

The gray water coming out of the kitchen and toilet sinks is first used to irrigate the hügelkultur garden, then to the northern windbreak ditch, and the remaining excess is transferred to the reed pond to be created in the pasture area in the north.

Rainwater Harvesting

Rainwater to be collected from building roofs is first collected in vertical water tanks in the northern parts of the buildings. After these water tanks are filled, the excess water is directed to the ponds in the pasture area. The plant beds on the south side of the ecocafe building were also designed as water tanks. Rainwater collected from the south side irrigates these plant beds and excess rainwater is directed to ponds in the pasture.

Ecopark Center

Ecopark consists of social areas where visitors can observe examples of permaculture and sustainable living practices and experience these practices in practice. The spaces here are designed to enable visitors to perceive the vision behind the Ecopark while having a pleasant and healthy time. Common features of all buildings: built with local and natural materials as much as possible (soil, clay, sand, straw, wood, stone…). Ecocafe and Activity buildings are designed with passive solar design principles.

Sustainability and Permaculture Examples, Application Area

• Water retention and land water management (collecting rain and snow water, increasing the water retention capacity of the soil, storing water in natural ponds),

• Food forest, pasture samples

• Natural structures, passive solar structures

• Clean energy (production of electricity and hot water from the sun)

• Examples of effective natural gardening and food production

• Recycling (compost, mulch, biogas)

Ecocafe

The Ecocafe structure, designed with Passive Solar Building principles, consists of two parts: Cafe and Practice/training kitchen. The cafe section, where foods produced with natural and sustainable methods will be offered with seasonal menus, has been designed in a way that visitors sitting outside can also receive service in addition to the indoor section for 50 people. Practice/Training Kitchen located on the Eastern Front of the Building. It was designed with the capacity and infrastructure to provide training on principles such as natural food processing and storage.

Activity Building

It is the building where various training, activities and workshops can be held. It is to the right of the Ecopark and separated from the square by the Ecocafe. In this way, it becomes easier to carry out many different works at the same time in the ecopark.

Passive Solar Design

Passive Solar Design is a building design approach aimed at minimizing energy use by using the advantages of location, climate and materials. A well-designed passive solar structure reduces the energy spent on heating and cooling the structure through energy-efficient methods. The two main structures in the Ecopark, the Ecocafe and the Activity Building, were designed by taking these principles into account: building sections, positioning, use of materials, and placement of openings.

gardens

Compost Area

Compost production and storage areas similar to the photo below were planned so that the organic materials produced by the ecopark can be transformed into valuable compost fertilizer. There are compost areas at the edge of the service area in the north of the ecocafe and in the east corner of the community garden.

Energy Modeling of Buildings

Ecopark is an exemplary area of 'sustainable living in harmony with nature' and is also a demonstration area. One of the examples that will be explained to the public will be that ecological buildings that use solar energy correctly in summer and winter and use effective ventilation and heat insulation provide significant energy savings. The energy performances of the buildings were examined in the light of data on the projects of the buildings, mechanical design information, interior and exterior lighting systems, building exterior shell construction materials, and all energy-consuming equipment. Energy performance comparisons were made with typical reinforced concrete structures with similar areas and volumes.

Energy Analysis of Buildings

Energy efficiency analyzes performed:

• High performance building envelope

• Natural cooling with ventilation chimneys

• Natural heating with greenhouse design

• Natural and artificial shading elements

• Efficient lighting system

• Ground source heating and cooling system

• Energy efficient kitchen

Energy Analysis Results

The designed building provides 55% energy efficiency compared to a standard building. When solar panels are taken into account, energy savings increase to 75%. Energy consumption is calculated as 37 kWh/m² per year, total energy consumption is 18,353 kWh per year

Transformation of Organic Waste

Organic waste from the kitchens is converted into composted fertilizer in the compost bins located in the service area in the north of the ecocafe building. Organic wastes from gardens and pasture areas (fruit/vegetable residues, leaves, herbs, ground tree branches, etc.) are converted into compost in the compost production area in the community garden, and the produced compost is used for the abundance of the gardens, food forest and plants in the pasture area.

Solar Energy

A solar water system was placed on the northern roof of the ecocafe building to produce hot water from the sun. It will be possible to produce an average of 9800 kilowatts of electricity per year with 20 solar photovoltaic panels of 400 watts to be placed on the southern roof of the ecocafe building. Similarly, a solar PV system can be installed on the south roof of the activity building and both systems together can meet most of the electricity needs of the farm.

Earth Energy - Heat Pump

A ground source heat pump system was considered for heating and cooling of the ecocafe. Thanks to the pipes that will be laid underground before the foundation construction of the buildings, the heat pump will benefit from the constant temperature of 10-12 degrees 2-3 meters below the ground in winter. In summer, fan coils inside the building will cool the building by drawing the heat inside the building and transferring it to the heat pump and then to the underground pipes and thus to the ground. In winter, thanks to the passive solar design, heat energy from the sun will be captured and stored on the south side of the building on sunny days, thus reducing the need for heating energy.
