MOTIVATION FOR PRODUCT TESTING

Assessment of flexible joints, (bio)Polyurethane frame windows and two shading systems on indoor 
environmental quality, complimentary to the results measured within PM&VL2, PM&VL5, PM&VL6, PM&VL7, PM&VL8 and PM&VL9.

Product description

Flex&Robust's flexible structural connectors: A Flex&Robust line of products is developed from Polymer Flexible Joints (PFJ) and is dedicated to structural and non-structural bonding of elements constructing civil engineering structures, made of various materials (concrete, masonry, wood, metal).
Indresmat's windows: KLIMA-PUR is a new top class in energy-saving windows & doors made from Polyurethane (PUR). Similarly to wooden windows & doors, KLIMA-PUR integrates a high-performance material with a circular design.
Pellini SpA's Integrated microfilm shading device: ScreenLine is a range of shading systems encapsulated within insulating glass units, which is designed to optimise heat and light gain, thus reducing air conditioning and heating costs and increasing living comfort. Today, the ScreenLine range offers a further shading solution: Wave.
Pellini SpA's retroreflective shading device: A solar shading device consisting of a venetian blind comprising retro reflective coating based on silicon dioxide micro beads.

Building description

The proposed building is located near the historical city centre at the campus of Cracow.

1-story building (plus unheated attic) with 103 m² channel ceiling slab roof, 110 m² facade, 103 m² concrete foundation slab, one external door and seven wooden casement windows.

Climate

Climatic conditions corresponding to Cracow. The driest month is February, with 49 mm of rainfall. The heaviest rainfall occurs in July, with an average of 107 mm. The warmest month of the year is July, with an average temperature of 19.5 °C. The lowest average temperature of the year occurs in January and is approximately -2.3 °C. The difference in precipitation between the driest and wettest month is 58 mm. Temperature fluctuations throughout the year are 21.8 °C. The lowest relative humidity during the year occurs in April (68.03%). The month with the highest humidity is November (84.63%). The least rainy days are expected in October (10.47 days) and the rainiest is July (14.63 days). City is in a very large valley. This unfavorable location makes natural ventilation of the city very difficult and for many days of the year the air speed is very low here. Due to the wide use of coal for apartment heating and intense urban traffic emission of pollutants is high, which causes a very high concentration of atmospheric particulate matters PM10 and PM2.5. Those unfavorable conditions affect the internal environment in the building.

Internal climate

Internal building climate conditions correspond to the external climatic conditions in Cracow.
