Energy problems in building
• Dependence on natural gas and
masut instead of own and renewable
resources
• Old heating equipment
• Low efficient technologies in municipal
heating and electricity supply
• Society’s unawareness of new energy
technologies
• Country’s orientation on fossil fuels on
governmental level

What do we need to make
it come true?

Energy Technologies

Passive technologies
It’s an approach to minimize all energy use,
irrespective of the fact that the
energy may come from
renewable resources.
One of the original Passivhaus
at Darmstadt, Germany

Passive technologies
The dark colours on this thermogram of
Passivhaus show how
little heat is
escaping compared
with traditional
building

Passive technologies
ØPassive solar building design techniques
(compact in shape, windows
oriented towards the south)
ØSuperinsulation
ØHeat recovery ventilation
ØLow-energy lighting

Passive technologies
ØAdvanced window technology
ØHeat exchanger
ØMicro-heat pump
The ability to control building
temperature using only the normal
volume of ventilation air is fundamental.

Active technologies
The production of
renewable energy and
energy conservation.
Examples: BedZET zero energy
housing in the UK
v Zero-energy house
v Plus-energy house

Active technologies
Possible sources of energy:
§Solar cells
§Wind turbines
Electricity
§Biofuels
§Solar collectors
§Waste heat from lighting Heating
§White goods
§Body heat

Heat pumps

Why heat pumps?

Why heat pumps?

Biomass potential
It is the fourth greatest energy resource
after oil, coal, and natural gas.
“It
can provide approximately
10% of all energy demand of Ukraine
(without a share used in other
economical branches) by 2015.” According to the Institute for
Technical Thermophysics of NASU
Especially it can replace natural gas for private houses
heating.

Municipal Waste Potential
Ukraine has a large potential for using wastes
as renewable resource of energy.
Waste
EU and US
example
Solid waste Sewages
Incineration Anaerobic digestion
Electricity District Biogas (70% methane)
Heating

Electricity production in Ukraine
• One nuclear reactor of 1000 MW
performance in case when all this capacity
is consumed by heat pumps could
substitute 100-120 boiler-houses with
average power of 30 MW!

Electricity production in Ukraine
What does pollute greater: one reactor or
hundred boiler houses???

Why are we speaking about non
renewable fuels?
Because we try to create a real image.
During 30 years, we will not be able to replace
all energy by renewable resources.
For Ukraine nuclear power is irreplaceable.
It will be good back-up system for renewable
resources.

System approach in building?

Implementation Solutions
Educational
• Bachelor's and Master's program with
scholarships and loans
• Special “Renewables” course in all Universities
• Holding Ministry contests and providing grants
• Participation in regional and international
projects
• “Using Renewables” subject in secondary
school

• Having specialists in designing,
implementing and maintaining technologies,
using renewables
• Public opinion includes need for renewable
resources

Implementation Solutions
Economical
• Establish renewables as the main energetic goal
• Provide low interest loans in business, using
renewables
• Performance-based subsidies, which are clear and
understandable
• Increased taxation on fossil fuels and decreased
on renewables

The market of renewables
and connected services
Popular use of the
renewables in houses

Indicators
Number/increase of heat pumps
Number/amount of low interest
loans, provided for building
Number of passive/active
systems used
Market of renewables and
services volume
Number of plants producing
specialized equipment

Conclusions
What we have tried to do during 15 minutes?
üExplain our vision of best future for Ukraine
üShow the most important mechanisms and
technologies to do it.
These technologies work in smart countries and
should be implemented in Ukraine.
