8. MAIN PROBLEMS IN THE HEATING
SECTOR
• Losses of heat in buildings reach 30%
• Losses of heat in lines - 17.5%
• 32% of housing stock require
refurbishment
• Average heat consumption in residential
buildings – 270kWh/m2
Average in Europe – 100-120kWh/m2
• Absence of metering devices
Program of modernization of housing maintenance
and utilities (2015)
REASONS
• Low energy prices
• Low interest of homeowners to pay
for refurbishment
• Low effectiveness of mechanisms
for maintenance and
refurbishment of buildings

16. RES OF FUEL SUPPLY FOR THE
RESIDENTIAL SECTOR
Natural gas and district heating
distribution systems were split to
• dense
• medium
• sparse locations
with corresponding investment costs
and efficiencies
Installation of automatic controllers
and heat metering devices was
included in the model
16
17. RES OF RESIDENTIAL SECTOR
TECHNOLOGIES
“Unment demand” process was added to monitor the gap between theoretical
thermal requirement and actual consumption and test different policies aiming
at reducing the unmet demand 17
Three additional
“virtual” processes:
• “Unmet” demand
• Savings from new
buildings
• Refurbishment of
buildings
18. PRELIMINARY RESULTS – TOTAL
RESIDENTIAL SECTOR
18
Natural gas rises strongly in the BAU
Refurbishment measures are not in the solution. Without any incentive, and
in spite of the high thermal needs, costs are higher than other options to
come to the solution

21. CHALLENGES, OPEN ISSUES
21/19
• Low quality and insufficient data on energy
different sources show different data
need to transform fuel-energy balances to IEA format, time
consuming
• Residential energy consumption survey has not been conducted,
data on energy split by end-use is not collected
• Few studies on energy demand projections in Kazakhstan
• Theoretical thermal requirement is difficult to estimate due to the
absence of data by building types, and corresponding U-values
• No studies on indoor air pollution and health effects from solid
fuels combustion in Kazakhstan
• Few studies on fuel poverty in Kazakhstan
21
22. FUTURE WORK
22/19
• Conduct scenario analysis with TIMES-KZK and TIMES 16RKZ model,
compare results
• Obtain drivers and elasticities from CGE model for Kazakhstan developed
by DIW Econ
• Get energy audit reports of buildings and disaggregate buildings by type of
building/age in the TIMES-Kazakhstan model
• Estimate fuel poverty in Kazakhstan with data from households survey
• “energy expenditure greater than 10% of disposable income”
• “households with energy expenditures higher than median level and whose
income after energy expenditures would be below official poverty line” Hills
(2012)
• Conduct a study on indoor air pollution and health effects from solid fuel
combustion
• Internalize external costs of health effects from solid fuel combustion in
TIMES-KZK model
