Erasmus+ CBHE project 561890-2015E-JP MARUEEB Erasmus+ CBHE project 561890-2015E-JP Intensive Course in «Energy Efficient Buildings» attended by Armenian and Russian Jr. staff Final presentation of the case-study Norayr Benohanian and Ruben Khachatryan St. Petersburg, 18th September 2017 Sezioni Fare clic con il pulsante destro del mouse su una diapositiva per aggiungere sezioni. Le sezioni possono essere utili per organizzare le diapositive o agevolare la collaborazione tra più autori. Note Utilizzare la sezione Note per indicazioni sull'esecuzione della presentazione oppure per fornire informazioni aggiuntive per il pubblico. Mostrare queste note nella visualizzazione Presentazione durante la presentazione. Valutare con attenzione le dimensioni dei caratteri, importanti per l'accessibilità, la visibilità, la registrazione video e la produzione online. Colori coordinati Prestare particolare attenzione ai grafici, ai diagrammi e alle caselle di testo. Tenere presente che i partecipanti eseguiranno la stampa in bianco e nero o in gradazioni di grigio. Eseguire una stampa di prova per assicurarsi che i colori risultino comunque efficaci e chiari in una stampa in solo bianco e nero e in gradazioni di grigio. Grafica, tabelle e grafici Scegliere la semplicità: se possibile utilizzare stili e colori coerenti, che non rappresentino elementi di distrazione. Assegnare un'etichetta a tutti i grafici e a tutte le tabelle.

Background Hypothetical village selected in Armenia . The village is not gasified due to its remote location. The villagers use mainly self-made, low-efficiency burners to heat their homes. There are no nearby forests, so the villagers use firewood delivered from remote forests. Increased cost of firewood annually (7.8% annually).

UNIGE – MARUEEB intensive course “Raising the energy efficiency of residential homes in the Armenian rural area through thermal insulation and replacing inefficient wood-burners “ Rural development Forest conservation Energy performance of residential homes Risk analysis Financial analysis UNIGE – MARUEEB intensive course

UNIGE – MARUEEB intensive course Risk management What are the risks associated with such a project? Clearly address all the stakeholders concerns by Risk identification, evaluation, control & feedback (ALARP method) UNIGE – MARUEEB intensive course

Risk control Long-term contracts for firewood supplies Using wood pellets Risk control

Energy performance of building Some of the parameters considered: Heated area (40% of house area) Calorific value of trees in surrounding forest Heat losses from roof, floor, doors, windows, envelope, etc. Types of insulation used, replacement of doors/windows No gas network connected UNIGE – MARUEEB intensive course

Energy performance of building Two separate models were used: Model 1: Uninsulated house with low-efficiency wood-burners Model 2: Insulated house with replacement high-efficiency wood-burners Comparison of the volume of wood needed for both models. (Model 2 will perform much better with about 8 times less firewood) UNIGE – MARUEEB intensive course

UNIGE – MARUEEB intensive course Energy performance (For the same thermal comfort) Heating season: October-April The uninsulated building (old wood-burner) would need: 18.29 cub.m. of firewood at a cost of €563 The innsulated building (new wood-burner) would need: 2.23 cub.m. of firewood at a cost of €68 UNIGE – MARUEEB intensive course

Firewood price escalation: 7.8% Financial analysis Firewood price escalation: 7.8% Discount rate: 6% Payback period: 8.78 years Internal Rate of return: 19% Net present value: 7490 € Project life: 20 years UNIGE – MARUEEB intensive course
