Smart Thermal Ceramic Roof Tiles

MOTIVATION:

• energy efficiency in buildings is a priority

• roofing area is significant in building envelope & 25% of heat

exchanges between indoor and outdoor environment is by the

roof

• “cool roofs” are beginning to be demanded

• a 2012 portuguese ceramic tile study had evidenced that

different roof tile colour can have a major influence in the

building energy consumption

OBJECTIVES:

• development of chromogenic tiles that changes solar radiance

reflectance according to the environment conditions

• change of optical properties with temperature »»

thermochromic materials

Smart Thermal Ceramic Tiles

TECHNICAL DEVELOPMENTS:

• optimisation of a synthesis method for the production of

nanostructured thermo chromic VO2 powder

• testing of powder deposition and adhesion on glazed

tiles

• prototype tiles production

• thermal evaluation of roof prototypes and computer

simulation

500nm

Smart Thermal Ceramic Tiles

RESULTS:

• functional coated ceramic tile that changes its reflectance

index in hot days

• increases solar radiation reflectance accordingt to the phase

change of coating material

• the reflectance change is in the higher energy range of the

solar spectrum (IR)

solar radiation spectrum at the earth surface reflectance index vs light wave length of the –Tiles for

different temperatures
