Introduction
Annual survey on energy consumption in industry, commercial and public sector sector in 2014
represents the survey on consumption of energy products in Montenegro in 2014. Within the
industry sector, the survey also collects the data on supply, production, sale, and stocks of energy
products.
This survey covers local units of enterprises, public and state administration, and entrepreneurs,
excluding private entities registered for performing a transport activity.
The purpose of survey is to collect the data on: (i) type of office buildings; (ii) building material; (iii)
type of heating; (iv) type of cooling; (v) type of lighting; (vi) type of hot water preparation; (vii) type
of food preparation; (viii) total consumption of energy and energy products used for performing the
activity.
The survey collects the data necessary for further development of official statistical system,
especially for the creation of complex energy balance. Thus, the survey results have multiple uses.
In addition to the creation of complex energy balance, it is a good basis for further harmonization in
the area of energy efficiency. This survey has a special contribution in the negotiation process of
Montenegro with the European Union, because there have been used Regulation (EC) No
1099/2008 and Regulation (EU) No 147/2013. The mentioned regulations represent a basis for the
harmonization of energy statistics with the acquis communitaire of the European Union.
Annual survey on energy consumption in industry, commercial, and public service sector in 2014
has been conducted in accordance with the Contract No 01-3859 of 1 December 2014, signed
between Statistical Office and Energy Community of the European Union. An implementation
agency for conducting the survey is the Energy Institute Hrvoje Pozar from Zagreb, on the basis of
Contract No UG-15-00034.

METHODOLOGICAL BASES
Subject and purpose of survey
The subject of survey is the consumption of energy products in Montenegro, but also production,
supply, stocks, type of office buildings, building material, type of heating, type of cooling, energy
consumption, consumption of hot water, energy used for food preparation and total energy
consumption.
Definitions
Building is a permanent structure that has a roof and external walls, built as separate usable unit
providing the protection against weather and other external conditions, and intended for housing,
performing an activity or for storage and keeping animals, goods, equipment for different
production and service activity, etc.
Building indoor space area refers to the space where the activity is performed. If the activity is
performed in several buildings on one location, then the area of buildings are summed up. The
indoor space area is represented according to the parts of building that have different purpose.
Reconstruction is performing construction and other works on the existing building by which the
following is done: outbuilding; building subordinate; replacement of installation, devices, plant, and
equipment by which the existing capacity is changed; has influence on building stability and safety;
changes important construction elements; changes technological process; changes external
appearance defined by the conditions for space arrangement. Reconstruction is not the same as
adaptation. The adaptation is a performance of building maintenance works and works with no
influence on building stability, i.e. individual buildings parts, and not considered to be building
construction.
Material of external walls refers to to the type of material a building is made of.
5
Type of building heating represents manner/manners of heating a building.
Individual stoves/heaters serve for heating individual premises. They may use different energy
products as the energy sources. The most important energy products that used individual
stoves/heaters are: electricity and firewood.
Central-heating boiler is type of heating produced in a boiler mostly using gas or electricity. The
heat produced is mostly distributed to the end location for heating premises through the system of
radiators, underfloor heating or exits for exhausting air. Central-heating boiler may be often used
for hot water preparation too.
Central individual boiler room is the type of heating produced in individual boiler room, mostly using
light heating oil, biomass, coal and other solid fuels. Produced heat is mostly distributed to the end
location for heating premises through the system of radiators; underfloor heating or exists for
exhausting air. Central individual boiler room may be also used for hot water preparation. This type
of heating can comprise also solar energy based heating used to heat larger reservoirs of water
delivered to the premises that should be heated. Solar heating is often combined with other types
of energy used in periods with no sufficient solar energy.
Common boiler room is the type of heating in residential and business buildings where the heating
is produced in one central room using light distillate oil or solid fuels. Produced heat is often
distributed to the end location for heating premises via the system of radiators or air ventilation
exists. If several buildings are connected to this central premise, than there is also a need to build
a distributive network. This type of heating can be combined with the systems for solar heating.
Heating by air–conditioning is the type of heating with the use of air-conditioners (local or central).
Type of cooling of building represents the way/s the building is cooled.
Local cooling systems are:
1. Split system - represents system of cooling where indoor and outdoor unit linked with
transmitter of cooling device. Air-conditioners are the most often split systems. These
devices are often used for heating rooms.
2. Multi split system - represents system of cooling where several indoor units is linked with
the outdoor unit.
3. Compact units- can be window or room devices. There is only one unit that is built in the
window or below the open window. It can be also in the form of portable cooling device.
Central cooling aggregates are devices with one or several outdoor cooling units cool the whole
building. Central cooling systems can perform several functions, in addition to the cooling. They
allow the humidity control and air ventilation.
Total energy consumption refers to the total consumption of all energy products in reference
year.
6
