TECNALIA RESEARCH & INNOVATION
Energy Efficiency in Buildings
• Buildings in Europe
– 40% Energy Demand
– 36% CO2 Emissions
• TARGET by IEA by 2050:
– Reduccion of 77% of the CO2
emmisions
“Energy Performance” of an average European building is poor. Themajority of energy in a building is spent to satisfy heating and coolingdemands
ECOFYS estimate that the addition of thermal insulation to existing buildings inEurope could decrease current building energy costs and carbon dioxide emissions bysome 42% or 350 million tonnes of CO2 emissions
Traditional Building Insulation Materials

Mineral family 0.030-0.040
Polystyrene-EPS 0.030
Polystyrene-XPS 0.040
Polyurethane foam 0.022
SPACE LIMITATIONS: 20/30 cm thick insulation layers are common in buildings, often
resulting in: Bulky constructions, Difficult detailing, Loss of space.
HOW TO IMPROVE ENVELOPE INSULATION?
Conventional Insulation Materials: Increasing the thickness of theinsulating layers.
Energy Efficiency in Buildings
Superinsulation Materials – Silica Aerogels
HOW TO IMPROVE ENVELOPE INSULATION?
Decreasing the thermal conductivity of the insulation materials.

EeB.NMP.2010-1 New nanotechnology based high performance insulation systems for energy efficiencyNANO E2B CLUSTER
� The Nano-E2B-Cluster is an initiative of the EU project officer
Georgios Katalagarianakis and PTA Marcel Dierselhuis.
� Starting date: September 2011
The main objective of the Cluster is to joint efforts in order to find
synergies and fields of cooperation that will allow the projects to be
more competitive. At the present moment efforts concerning common
demonstration, standardization and dissemination activities are in
progress.
