Yerevan 22 November 2019 Cooperation with Energy Efficiency (YEE) Project (1)

UNDP-GCF Project provides technical assistance to the Municipality of Yerevan in implementing the “Yerevan Energy Efficiency (YEE) Project” aimed at promotion of energy efficiency (EE) improvements in municipal level.

In the first phase, the Project has focused on implementation of EE measures in 31 kindergartens in Yerevan.

“De-risking and Scaling-up Investment in Energy Efficient Building Retrofits” Project Cooperation with Yerevan Energy Efficiency (YEE) Project (2)

Energy Efficiency measures proposed for kindergartens include:

1. Building shell thermal insulation 2. Changing of doors and windows 3. Replacement of inefficient luminaries/lamps with LEDs 4. Replacement/regulation of heat supply systems 5. Introduction of ventilation systems (with heat recovery units) 6. Furthermore, integration of solar energy systems (solar PV and solar thermal) have been included in general scope of works Technical designs are under finalization for kindergartens and are being/have been verified/approved by independent examination body.

Comprehensive Energy Audits have been carried out in kindergarten facilities.

According to the results, average Specific Heat & Ventilation Consumption for all kindergartens accounts for 303 kWh/m2/year, whereas actual average consumption is 118 kWh/m2/year. This translates into an average actual comfort level of 40%.

Average Specific Heat & Ventilation Energy Consumption (Normative, Before) 303 kWh/m2/year

Specific Heat & Ventilation Energy Consumption (Actual, current) 118 kWh/m2/year Specific Energy Consumption (SEC) (Actual, current) 162 kWh/m2/year

Average Specific Heat & Ventilation Energy Consumption (Normative, After) 105 kWh/m2/year

CO2 emission reduction from all refurbished facilities accounts for 2,295 tons/year.

“De-risking and Scaling-up Investment in Energy Efficient Building Retrofits” Project Rehabilitation of Child and Youth Center #3 in of Yerevan (1) According to the Statement of Intent between YM and UNDP , initial design documents, prepared by YM were revised by UNDP in order to introduce comprehensive measures for upgrading seismic durability of the building and ensure energy efficiency improvements. Measures introduced by UNDP: Structural reinforcement works, installation of windows and doors with higher thermal characteristics, roof insulation, energy efficient lighting system and modern heating system with condensing boilers.

UNDP invested about AMD 47 million (about USD 100,000) towards application of energy efficiency improvement measures.

As a result, energy efficiency of the building is improved by more than 50%, and in terms of environmental benefits, CO2 emission reduction accounts for 250 tons/year.

The energy efficiency measures in public buildings can ensure the cost savings of municipal public budgets, at the same time will contribute to the environmental objectives in reduction of greenhouse gases.

“De-risking and Scaling-up Investment in Energy Efficient Building Retrofits” Project Rehabilitation of Kindergarten #160 in -Zeytun District of Yerevan (1) According to the Statement of Intent between YM and UNDP Armenia, initial design documents, prepared by YM were revised by UNDP in order to ensure energy efficiency improvements for which UNDP invested about AMD 12 million (about USD 25,000). Measures introduced by UNDP: Insulation of the attic floor, partial insulation of external walls, replacement of old windows and doors with new energy efficient units, installation of LED luminaires, replacmenet of cast-iron radiators with core steel panel radiators.

“De-risking and Scaling-up Investment in Energy Efficient Building Retrofits” Project Rehabilitation of Kindergarten #160 in Kanaker-Zeytun District of Yerevan (2) As a result, energy efficiency of the building is improved by around 40%, and in terms of environmental benefits, CO2 emission reduction accounts for 23 tons/year.

Street lighting – 75 applications “De-risking and Scaling-up Investment in Energy Efficient Building Retrofits” Project UNDP-GCF project Technical Assistance to the State Community Subvention Programme (2)

Several communities have received technical recommendations through phone calls, working meetings, written ToRs and submitted designs by UNDP-GCF expert team. These include: . 1 Cultural House Project in Lori region . 2 Multi Apartment Buildings Project in Lori and Syunik regions (total of 17 residential buildings) . 8 Kindergartens Projects in Gegharkunik, Kotayk and Lori regions . 1 Solar PV project in Lori region . 33 Street Lighting projects in various regions Technical assistance has been delivered towards introduction/inclusion of energy efficiency measures such as thermal refurbishment of building shell components, efficient heating, efficient lighting and application of solar energy systems. “De-risking and Scaling-up Investment in Energy Efficient Building Retrofits” Project UNDP-GCF project Technical Assistance to the State Community Subvention Programme in Sisian UNDP is involved to ensure compliance with minimum energy efficiency and national building code requirements, appropriate consideration of the design quality and technologies and materials application. UNDP-GCF project team has revised the initial design and integrated energy efficiency improvement measures for retrofitting 5 multi-apartment buildings in Sisian (attic floor insulation) in the framework of this collaboration.

CO2 emission reduction from all 5 refurbished buildings accounts for 59.6 tons/year. “De-risking and Scaling-up Investment in Energy Efficient Building Retrofits” Project THANK YOU!
