Thermo-technical retrofitting ofpublic buildings

in Western Mongolia

Implemented by

7 November 2014 NEXUS Workshop: Thermo-technical retrofit t ing of public buildings in Western Mongolia

Implemented by


Energy Efficiency Project (ENEV phase III)A cooperation between• Ministry of Energy• Cabinet Secretariat• SDC• GIZ (BMZ)

A general project presentationof the activities

in the three components for2014 – 2016

Improving the governance ofEnergy Efficiency

Implemented by


Outcome 3: Public institutions, companies,

and households have intensified efforts and

increased investments in the area of Energy

Efficiency and energy conservation

Outcome 1: Compliance with Budget and

Procurement Laws relating to capital

investments at local level has improved

Outcome 2: Improved Energy Efficiency of public buildings in

Khovd and Zavkhan aimags demonstrated

Mongolian Partner:Cabinet Secretariat

Other Partners:Energy Regulatory Commission

Outcome 2: Improved Energy Efficiency of public buildings in Khovd and Zavkhan aimags demonstrated

Output 2.1 Qualifications of the private sector (Construction companies, Specialists, Architects, Engineer, Suppliers and Service Companies) at soum and aimag level for the implementation of energy efficiency projects in public buildings have improved

Output 2.2 Evidence of the benefits from thermo-insulation of public buildings is available

Output 2.3 A conducive environment for the rational and structured operation, maintenance and rehabilitation of public buildings is created

Output 2.4 The users of building and heat suppliers have reached an agreement on energy efficiency and energy savings based on evidence based dialogue

Output 2.5 Strengthening the ability of the local government to develop action plans, standards and protocols and to enforce them

Two buildings will be pilot cases to show how Energy Efficiency (= insulation) in practice can be carried out.

There is a matching fund (50 – 50 basis) arrangement provided for Energy Efficiency renovation works in public buildings

What do you think is the main reason for the public buildings being cold?

Heat loss

Insufficient heating

Expensive coal andinsufficient supplyBuilding quality

Extreme coldtemperaturesAged building

Outcome 3 outlines support to establish Energy Managers and Energy Auditors. As a part of their (planned) tasks, there is a need for some kind of standardized Energy Efficiency Certificate.

The Energy Efficiency Certificate consists of standard parameters

< – – Energy Efficiency Certificate for the Kindergarten in Khovd to be renovated (draft).

The target is to improve the standard (energy consumption/m2 and year) from E to C.

A 50% – or more – reduction of energy consumption is estimated.

The evaluation will be accomplished after the winter season 2014/2015.

This is not a very inviting environment for a 4-year old girl. Urinary infections are probably rather common.

The renovation has started.• Ceilings (roofs)• Walls• Windows• Doors• Floors

Implemented by


58 windows were changed to 2-glass vacuum type.Most of the materials were produced locally.

It was a very clear division between female and male tasks.

The task to instruct how to get a right angle could be a challenge.

And how to use a label also needs thorough and hands-on instructions.

The principle for the wall insulation method.

Cooperation with the TVET project provided training of the staff of the construction companies involved.

The “students” got a certificate for their participation in the training and practical work.

Standards of various kinds are to be implemented.Home made solutions are adapted to the local conditions.

The radiators were more or less completely clogged.

Monitoring of• indoor temperature• outdoor temperature• incoming heating water• outgoing heating waterwill provide valuable facts for evaluation.

Khovd Kindergarten #5 insulatedDifference between supply and return temperatures is much less than in the other building.

The difference between supply and return temperatures increases when it gets cold.

Data will be gathered on a 15-minutes bases from 2 insulated + 2 not insulated kindergartens. Hopefully there will be a lot to learn from this data.

Implemented by


Outdoor signboards have already increased the interests in Energy Efficiency and what the project is doing.

Implemented by


Showing that the indoor temperatures are still high during very cold periods will be hard facts to prove that insulation is efficient.

There is a matching fund (50 – 50 basis) arrangementprovided for Energy Efficiency renovation works in public buildings.Approximately six additional public buildings will be refurbished.Invitations / applications sent out to local governments to participate in theprogramme.

Requirements to provide technical and financial information.

7 applications received.

Selection process ongoing. Bidding, evaluation, and contracting will follow.

Work will start in May 2015.7 November 2014 NEXUS Workshop: Thermo-technical retrofit t ing of public buildings in Western Mongolia

Output 2.2 Evidence of the benefits from thermo-insulation of public buildings is available

Implemented by

The cost for the refurbishing of the kindergartens is around EUR 125,000 each.With the current heat tariffs (and generally the energy tariffs) there is no direct economic incentive to insulate buildings.Life cycle cost is an “unknown” parameter.

However, it is probably better to renovate (not too) old Soviet style buildings than to demolish the old one and construct a new!?
