OVERVIEW OF EXISTING SITUATION WITH THE
EE LEGISLATION IN GEORGIA

In Georgia the buildings sector accounts for over 40% of energy
consumption in country’s energy balance. Buildings, especially the
residential ones, are the biggest energy (and money) wasters and
largest sources of greenhouse gas emissions in the country;

For the buildings sector new national construction standardization
documents (codes) have not been adopted yet. The first draft of the
new Georgian Construction codes that will reflect energy efficiency in
buildings it is anticipated in December 2013.

In 2007 Georgia has adopted Law on House ownership, that lays down
foundation for forming HOA management.

PREREQUISITES FOR ENERGY EFFICIENT
HOUSING ACTION PLAN IN GEORGIA

In 2012 Georgia requested assistance of UNECE for development
of a national action plan on energy efficiency of the housing sector,
that had been approved.

The 4 -the International Forum: Energy for Sustainable Development
followed by the National workshop, took place in September in
Tbilisi as UNECE‘s direct response to the official request of
Government of Georgia aiming at outlining a major situation and
support activities for a EE Action plan for housing sector.

In 2011 Tbilisi City Hall signed Covenant of Mayors Initiative, a step
which led to development of the Buildings sector Sustainable
Energy Action Plan(SEAP) for Tbilisi City with the helping hand of
the USAID NATELI/ SDAP Center.

MAIN CHALLENGES FOR GEORGIA IDENTIFIED
BY NATIONAL WORKSHOP
Development of National strategy (plan) for energy efficiency that will
outline priority areas:


Laws and regulations
Financial mechanisms (policy, schemes, capability of the banking sector,
etc.)
Management and rehabilitation of housing stock
Improvement of technical capacities
Rising public awareness of citizens

PAST EXPERIENCE - STRATEGY OF TBILISI SEAP

The overall strategy for the buildings sector SEAP in Tbilisi was set up
aiming at reduction of greenhouse gas emissions through the
sustainable use of energy resources and reduction of the overall energy
consumption.

Underlying assumption that led to setting this goal is as follows:
- huge heat losses in winter since the main part of targeted building
stock subsectors were built during the Soviet era.

Two target subsectors:
- municipal buildings
-residential buildings


PROPOSED MITIGATION MEASURES UNDER
TBILISI SEAP

Action plan rehabilitation measures:
- upgrading/insulation of building envelopes;
- installation of modern energy efficient heating systems;
- replacement of incandescent bulbs with fluorescent ones;
- implementation of pilot “low energy consumption buildings” projects;
- utilization of “renewable energy resources” for heating and domestic hot
water supply purposes.

FRAMEWORK FOR IMPLEMENTATION OF THE
SEAP MEASURES

TBILISI SEAP -PILOT PROJECT(ESIB)

Multi-apartment 9-storyed single entrance residential
building built in 1978 consists of two identical units A
and B connected to each other by the staircase.

Building has been selected by Tbilisi municipality,
since it is considered to implement heat insulation in
one of the units with the objective of comparing actual
results of heat consumption between the heat
insulated unit and the unit without heat insulation.

It is planned to monitor heat consumption and
compare the data with the energy audit data.

MUNICIPAL ENERGY PLANNING SOFTWARE TOOL
DEVELOPED BY SDAP CENTER IN PARTNERSHIP
WITH WINROCK INTERNATIONAL(INRMW PROJECT)
22
MUNICIPAL ENERGY PASSPORT

An instrument to help the local governments and other interested stakeholders
to evaluate the severity and extent of the existing energy problems as well as to
prioritize these problems in order to develop appropriate instruments to solve, or
at least help ameliorate them;

Can be modified as needed in order to accommodate additional analytical and
decision-making features to satisfy the future development needs of small
territorial units like municipalities and/or regions of Georgia

It is interactive, bilingual (Georgian/English), enables users to choose among
variety of options of data presentation (numerical, %, charts, etc), to retrieve and
store data
Operating System: Windows XP/Vista/7 or Windows 8
Screen resolution: minimum 1024/768
Ram:2GB (or higher)

MUNICIPAL ENERGY PASSPORT OBJECTIVES
Energy Passport meets the following basic characteristics:




It is not a model of any particular energy system, but rather an
instrument that can be used to create models of different energy
systems;
As a database it can provide a comprehensive system for maintaining
energy information;
As a policy analysis tool it can assess the effects - physical, economic,
and environmental - of alternative energy programs, investments, and
actions;
It is expected to be used for forecasting energy balances and
development of the energy efficiency action plans for each watershed
(municipality)
