Download to read offline

In 2017 startten de Hogescholen Saxion Enschede en Hanze Groningen Bouwtex, het onderzoek naar de mogelijkheden van textiel voor de bouw in het kader van renovatie en herbestemming van gebouwen.

Op 15 januari 2020 is het onderzoek afgerond met een eindevent. Hier de presentatie over de kansen van het gebruik van textiel in de bouw van Christian Struck, lector Sustainable Building Technology Saxion: Potential of textiles for building renovation.

  14. 14. Field of tension Building use Energy generation*, storage*, distribution and delivery (HVAC systems) Building structure Reducing energy consumption and increasing resource efficiency requires an integrated systems approach! 4
  15. 15. Design approaches change. (Lysen, 1996) [1996] [2014] 1. Cutting the energy demand including the use of designs, materials and equipment that are more efficient; 2. Produce energy locally from renewable and otherwise wasted resources; 3. Using smart grids generating a surplus in some buildings and feeding it into the grid. 15(WBCSD, 2014)
  16. 16. System definitions for energy-positive buildings evolve. Type 1: Annually generated energy (QR) equals or exceeds the buildings demand (QD). The demand includes energy used for providing domestic hot water (QDHW), space heating (QH), ventilation QV, as well as small power and electrical equipment (QSP). QR = QD = QDHW+ QH+QV+QSP (1) Type 2: As type 1 but the demand additionally includes the embodied energy for the building over its life cycle (QEM). QR = QD = QDHW+ QH+QV+QSP+QEM (2) Type 3: As type 2 but the demand also includes the energy required for user induced mobility. QR = QD = QDHW+ QH+QV+QSP+QEM+QMob (3)
