Energy efficient housing for sustainable development

Workshop Tirana, 07-08 July, 2014

Key Facts

40% (240’000) of buildings are older than 30 years (Census, 2011) 4-5% of buildings are with thermal insulation Despite some exceptions, construction without thermal insulation continues Wide use of electrical equipment in housing Approximately, 9 to 10% of houses are not appropriate for living (Andoni,

2009) Most emergent interventions in housing according to citizens (Co-Plan,

kW

This apartment has reduced with 15% the energy consumption after the first year of being thermo-insulated

EE Project in Fier Outcomes

Theoretical energy improvement up to 40-50% (energy losses), while the economic up to 1% (electricity bills).

Gv reduction from 1.8 to 0.63 (W/m3 ºC) (standard 0.59)

The intervention brings improvement living comfort and potentially increases house value.

Investments for energy infrastructure: 2400Euro/family – are they affordable for all families?

Economical and energy benefits are considerable but not enough to fully attract interest.

EE Project in Fier Main findings

Legal framework for co-ownership are difficult to be applied Dominant mentality: “government is responsible” Energy renovation and improvement is very effective and has

to be standardized Need for specialists (design, installation, maintenance, audit) need for standards in construction, renovation, and

maintenance of building stock Need for education/research in passive building
