BouwTex: Potential of textiles
for building renovation
Context o GHG reduction initiatives (-49% CO2 emissions,
by 2030) lead to more stringent building energy
regulations.
o Localized renewable energy supply strategies
(potentially) lead to enhanced stress on energy
distribution networks.

• Two days on-site
• Six façade elements
• Three activity
categories:
• assembly,
• waiting,
• searching
Challenges, parametrizing models
Infographic + Lead Generation Model
• Very diverse facade elements
• Workstations with one and two workers
• Limited measurements per activity and
process step
• Unexpected process interruptions

Reducing energy consumption and increasing resource
efficiency requires an integrated systems approach!
4
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)
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)
… there are new building performance
indicators in development!

Smart Readiness Indicator
18
Facilitate a greater uptake of smart technologies is
expected to result in significant energy savings in a cost-
effective way, while helping to improve comfort and
occupant satisfaction and enabling buildings to play a key
role in smart energy systems.
Smart Readiness
19
The flexibility of a building's overall electricity
demand, including its ability to enable
participation in active and passive as well as
implicit and explicit demand-response, in
relation to the grid, for example through
flexibility and load shifting capacities.
Aspect 1: Building – Grid interaction
Smart Readiness
20
The ability to maintain energy efficiency,
performance and operation of the building
through the adaptation of energy consumption
for example through use of energy from
renewable sources
Aspect 2: Energy management
Smart Readiness
21
The buildings ability to adapt its operation mode
in response to the needs of the occupant
paying due attention to the availability of user-
friendliness, maintaining healthy indoor climate
conditions and ability to report on energy use
Aspect 3: Building - User Interaction
22
How do we communicate with the user?
?

  • 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. 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. 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)
  • 17. … there are new building performance indicators in development! 4
  • 18. Smart Readiness Indicator 18 Facilitate a greater uptake of smart technologies is expected to result in significant energy savings in a cost- effective way, while helping to improve comfort and occupant satisfaction and enabling buildings to play a key role in smart energy systems.
  • 19. Smart Readiness 19 The flexibility of a building's overall electricity demand, including its ability to enable participation in active and passive as well as implicit and explicit demand-response, in relation to the grid, for example through flexibility and load shifting capacities. Aspect 1: Building – Grid interaction
  • 20. Smart Readiness 20 The ability to maintain energy efficiency, performance and operation of the building through the adaptation of energy consumption for example through use of energy from renewable sources Aspect 2: Energy management
  • 21. Smart Readiness 21 The buildings ability to adapt its operation mode in response to the needs of the occupant paying due attention to the availability of user- friendliness, maintaining healthy indoor climate conditions and ability to report on energy use Aspect 3: Building - User Interaction
