Video presentation of the projectMicro-locations will try to maintain practical dialogue with users
eager to socialize, or to spend some time in solitude or just to play.
With small dimensions, made of warm and natural materials, protected
from unwanted environmental effects, these “inner spaces” will give a
qualitative way of extended housing.
One of the most important features of the site is its microclimate,
which is defined by the climatic variations of the regional climate. To
these exceptions is due to the difference of location in relation to
altitude, slope and its orientation, configuration and proximity of
large water surfaces.
The position of the complex should be located studying the history of
the place, the local micro-climate, winds and weather patterns, solar
orientation, access to public transport and the form of surrounding
buildings.
Optimal form of a plot is rectangle, with the wider side directed to
east-west, and the shorter one in the north-south, in order to develop
the objects along the east-west axis (passive solar heating and
ventilation). Optimal incline is toward the south with gentle slopes of
15°, because that way we can provide better sun exposure, improve the
micro climate, ease embed of the objects and allow easier drain.
Embedding and use of the soil as isolator and heat storage offers great
benefits. Permanent, constant temperature under the soil (around 12°C),
provides savings for heating and cooling the objects.
The essence of this architectural concept means that the knowledge and
application of the physical and natural laws (heating, cooling, air
circulation and thermal isolation) can make object itself to act as
regulator of heat. Solar heating is ideal for our climate. Taking advantage of large
number of sunny days results in better heating. Solar, in relation to
other ways of heating, is ecologically acceptable. This system is
independent and can be used where there is no municipal infrastructure.
In passive solar architecture, natural environment factors are taken as
the most important elements of the receipt of energy. That’s how
objects can act as “energy facilities”.
In designing and planning housing complex, my main options were :
choosing the right location, energy efficiency, use of healthy
materials, recycling atmospheric water, a high degree of thermal
isolation, organic design, easier access for disabled persons and
intense use of greenery (plants).
Setting the complex to specific location - trying to make minimum
intervention on the terrain morphology, the appearance of landscape and
natural environment - reaches a higher quality level of living. All the
green areas which are possessed during the construction have been
“returned to nature” through “green roof”, as the objects’ “fifth
facades”.
In order to improve the energy efficiency and reduce carbon dioxide
emissions in the atmosphere, the complex is isolated using thermal
isolation in thickness of 25-30 cm for external walls and three layers
glass. North side of the complex is partially buried with soil, which
is an excellent thermal isolator.
All atmospheric water from the upper plateau, objects’ roof and
drainage pipes, are collected and used for maintaining (watering)
greenery and in toilettes(for washing toilet bowls). Whole system
consists of three chambers. The first is the preliminary cleaning-
deposition of rough waste (number 1). The same chamber serves as a
settling tank for sludge. Mechanically treated water goes in the
bio-film reactor (number 2). In this chamber bio-film certainly cleans
the pollution. Later, the water goes in the chamber to the secondary
treatment (number 3) and proceeds to drainage cylinder.
Cost-efectiveness:
If we calculate costs in the winter season -for heating and for cooling -during the summer, comparing a
one -floor dugout with residential area of 140m² and classical house with the same area, with identical
basic thermal isolation (5cm thickness), we obtain the following informations:
Annual energy consumption for additional heating of the dugout : 4.000kWh
Annual energy consumption for heating equivalent classical house: 20.000kwh
Facade’s surface of the solar dugout is only 1/10 of a classical house. That’s why costs for rendering and
maintaining of the dugout facades are 1/10 lower than the same ones for the classical house.
Because of it’s position in the ground, no matter how big is the dugout, does not require any lighting
conductor installation, as well as outlets for taking water from the roof.
Use of the atmospheric water for cleaning toilets and watering plants , use of wind energy for house
ventilation, setting „the green filter“ (plants) over the road, and recycle of household waste..
Price for the classical residential house in Serbia is 400-550 euros per square meter, while the price of
square meter for dugout would be 350 euros.
The project can be run in any part of the world. It is important to clearly get a southern orientation of
the object and to find gentle slope of the ground.
