The SGP GEF project ‘The modernisation of the
greenhouse of the Samarkand State University as a
model of an energy-efficient social object’
History
• The greenhouse was built in 1969, under the higher plant taxonomy department,
on the initiative and under the guidance of Academician Turakulov, the rector of
the Samarkand State University.
• As a result of scrupulous work, which continued for many years, a unique
collection of various plants was gathered in the greenhouse of the State
Samarkand University.
Why the project was necessary
• In the cold winter of 2008, more than half of the unique
plants of the greenhouse died, which was caused primarily by
the outdated equipment.
Description of technical problems
•
•
•
•
•
•
Outdated, ineffective heating system;
Cracked and broken glass;
Leaky water supply system;
Absence of conditioning system;
Outdated ventilation system;
Absence of artificial illumination.
Administrative mistakes
• Many plants were not calculated and registered;
• Not all of the plants were labelled;
• Most of the Samarkanders and guests of the city were not
aware of the greenhouse.
Project measures and results achieved
I. Modernisation of the
greenhouse power supply
system
Installation of gas
equipment for the
heating system of the
greenhouse
Heat insulation
Light protection and
temperature
regulation systems
Solution of the power
supply problem
A new boiler house
was built, where a
new boiler was
installed; the
heating system was
repaired;
polycarbonate glass
and light protection
systems were made;
the illumination
system was
installed.

Heating system
• Before the project
• After the project
Gas boilers with gas burners НР16
New automatic floor gas boiler «Kiturami»
KSOG-200 R
Advantages
The new boiler consumes 270 cubic metres of gas per day; the old gas boilers used 700 cubic metres of gas (at
a temperature of –20º С; thus, the consummation of gas is reduced, which resulted in the reduction of
carbon dioxide emission – 1.8 tonnes (in comparison with the 5 tonnes before).
Heating system
•
Before the project
• After the project One
Three-
phase circulation pump
phase electric pump (1,500 Wt)
(1,500 Wt)
Advantages
The one-phase circulation pump consumes 2.5 times less electricity in comparison with the threephase one of the same power. The boiler house is also equipped with accumulator inverter power
supply system (two accumulators 24Wt /190 Ам), which will secure the regular work of the boiler
and pumps.
Heating system
• Before the project
• After the project
Six metal heating pipes 100 mm in
diameter which functioned and 12 pipes
which did not. Total length – 1,350 m.
All the pipes were a part of the
supporting construction.
The system of heating plastic pipes
called ‘Spider Web’ with the total
leangth of 1,280 m, 20 and 50 mm
in diameter.
Advantages
The new ‘Spider web’ system runs under the inner surface of the greenhouse, which
results in an equal distribution of heat in the whole greenhouse. The pipes are not subject
to corrosion, are easily installed, with the warrant of 50-60 yearrs.
Glass
• Before the project
•
Old standard glass, 4-5
mm thick
After the project
Crystalline iodic polycarbonate, 1,500 square
metres, 10 mm thick, with the size of the sheet
2,100 mm by 6,000 mm
Advantage
The light transmissibility of the crystalline polycarbonate is 30,000 lux, of the iodic one –
6,000, which means that the new glass transmits 30% less ultraviolet than the former glass.
The heat transfer is 6 times as little as that of the old glass. The polycarbonate is 200 times
as strong as the ordinary glass; it is also fire-resistant, wrinkling at high temperatures, but
not burning (melting temperature – 250 degrees, burning temperature – 5,400 degrees).
Water supply and watering systems
• Before the project Watering with
the help of a hose
• After the project Sprinkling
system
Advantages
The sprinkling system: water is evenly sprinkled upon the plants, thus helping to save water in
comparison with the old system.
Water supply and watering systems
•Before the project
•After the project
Reconstructed pool
Old leaky pool
Advantages
The old pool lost 2 cubic metres of water daily. The reconstruction of the pool
made it possible to avoid these water losses
Conditioning and ventilation
systems
• After the project New
Before the project
The conditioning system
did not exist
air conditioners installed
Advantages
The new air conditioning systems help to maintain normal temperature within the
greenhouse in summer and winter and are very effective.
Illumination system
• Before the project The
illumination system did not function
• After the project The
illumination is restored completely
Advantages
38 energy efficient lamps were installed, 36 Wt each, and 2 lamps 30 and 10 Wt accordingly.
The old electric wiring was replaced by new one. The life time of such lamps is 10,00012,000 hours and energy consummation is 2.5 times less.
Illumination system
Before the
project
There was no photoelectric system
After the project
Solar panels
Advantages
The photoelectric system uses solar energy and will provide electricity
to illuminate the greenhouse in case of emergency
Project measures and results achieved
II. Improvement of the
greenhouse activity
Labelling of plants
and creation of
electronic catalogue
available in Internet.
 Working out of a
series of excursions for
various target groups
Guide training for the
workers of biological
faculty
Informative and visual
electronic catalogue
(available on the web-pages
of the university and SGP
GEF). Interesting excursion
programme for a wide circle
of visitors (in three
languages). All the plants of
the greenhouse are
identified and ccatalogued
Perspectives
•
Planting of rare and local species in the territory at the side of the greenhouse
(sea-buckthorn, oleaster, tamarisk, saltwort, tulips etc.) in 2012
•
New excursion route ‘Landscapes of Uzbekistan’ and relevant plants
(mountains, adyrs, tugais, desert)
