Lack of access to urban facilities and infrastructures and the material transportation complexity were the challenges that led to forming the main concepts of the project; Accordingly, active and passive energy supply solutions and the use of local materials became the leading design answers in this project.
The Dochenaran project is located in the Dochenaran Valley, 28.5 km from the city's infrastructure. Since this project deprived of electricity, water, and sewage networks, renewable energy has been used to supply the required energy. This complex consists of the main building and the guest building, located 60 meters apart. Both of these buildings are built on two-story concrete structures and belong to the years 1996-1997. thereby, these structures have been re-examined and reinforced. Respectively, the built-up area of the main and the guest buildings is equal to 360 M2 and 274 M2. When this project was included in the design team agenda, the skeleton and structure were built, and there was no access and connection between the project and the urban infrastructure; Simultaneously, materials were not accessible due to the unique project's location. Therefore, the design team carefully examined all the constraints in the project, including infrastructure accessibility and energy supply, quick and easy access to building materials, etc., with intending to create a project with sustainable and environmentally friendly architecture and supply the necessary power from renewable energy, tried to turn these constraints into opportunities.
Utilizing solar energy to generate and store electricity by solar panels; Applying solar energy to heat water and Floor heating system; Using thermal insulation on the exterior surfaces of buildings, including roofs and walls, as a passive solution to save energy and prevent waste; Collection, Purification and storage of seasonal river water and natural springs to supply water; Use of local materials, due to easy accessibility to minimize interference in the natural environment and design a project with an approach of adaptation to the environment and the surrounding nature; Among these cases, we can mention the thatched facade, which in addition to acting as a thermal insulator, has led the project to coordination and reconciliation with the environment and the surrounding bed; applying stone retaining walls - with local stones - that have been executed in dry (Gabion) to create a stable site and prevent gradual soil erosion on sloping surfaces; Use of The dry construction techniques to Conserve the groundwater sources, including the implementation of interior joinery of buildings and use of drywall system, as well as the Gabion walls in landscaping; harvesting Surface runoff water of the site, storage, and consumption in the form of drip irrigation system in green spaces and gardens.
Use double-glazed aluminum thermal break windows with double-glazed windows and wooden shutters in the Exterior windows casing to control the heat and prevent waste.
In this project, passive and active design solutions have been used to supply, store and distribute energy for both buildings. Certain methods have been used to stabilize the site and supply the required water for drinking and irrigation.
