Where can “Smart Ceiling contribute” to sustainability

  • Integrated Design Process:

Relevant qualifications and subject areas are included in the planning process.
If guidance of ”Smart Ceiling” is included early in the design process, it may be possible to build lower or more floors. Ventilation systems can be minimised and reduce installa-tion costs.

  • Life Cycle Assessment (LCA) – Primary Energy

3 Resource Indicators:
• consumption of non-renewable energy
• consumption of primary energy
• share of renewable primary energy
With ”Smart Ceiling”, ventilations systems should only be dimensioned according to volume of fresh air, as energy can be added via fan coils. Less volume of air results in a smaller duct system and lower energy consumption.
”Smart Ceiling” has lower pressure drop, which also provides less energy consumption.

  • Thermic Comfort:

Users’ satisfaction with the indoor climate; no excess temper-ature, draught or cold radiation.
• operative temperature Summer and Winter
• humidity Summer and Winter
• draught Summer and Winter
• radiation- and floor temperature Summer and Winter

”Smart Ceiling” causes no draught or condensation problems and produces 100 Watt/m2 in indoor climate category A.
JS Koncept’s calculation programme, developed by The Danish Technological Institute, makes a complete and accurate calculation of air and temperature. This calculation is made for all rooms and equals as documentation for the system. With this documentation it is only necessary with regulation for the room and not for every inlet diffuser.

  • Indoor Air Quality (Knockout-criteria, where a minimum score is needed):

The purpose is to secure the users’ comfort and health.
Especially schools and child care centers are important. Gradually, it is well-documented that children are particularly sensitive to the innumerable impact of the indoor climate and that it may affect students’ well-being and, in particular, learning; if the indoor climate in the classroom is not good enough.
This can be avoided by not having too high concentrations of harmful substances and obnoxious smells.

Air Quality can be divided into 2:
”The Experienced” and ”The Healthy”
”The Experienced”
• too low humidity
• smell
• too high/low temperature
• draught

”The Healthy”
• degassing from material
• degassing from people
• particles by burning
• moisture build-up
• radon

  • Indicators

• CO2 concentration below 1000 ppm
• measuring of volatile organic compound (VOC). TVOC-concentration below 3000 µg/m3
• formaldehyde concentration below 100 µg/m3

All components of the metal ceiling are free from formaldehyde and are therefore assigned to Class E1.
The manufacturer declares that no substances were used for manufacturing metal ceilings, which cause hazardous emissions, thus no initial test is required. Furthermore, sub-structure compo-nents and covering layers were tested for compliance with the reference values for volatile organ-ic compounds (VOC) according to the assessment system of the German Committee for Health-Re-lated Evaluation of Building Products (AgBB).
”Smart Ceiling” is not a part of the problem, but part of the solution because the system supplies fresh air.

  • Users’ possibility for controlling the indoor climate:

Focus on the fact that users, to a great extent, can control ventilation, solar radiation and glare shielding, temperature and lighting.
”Smart Ceiling” is controllable through CO2 and temperature of plain operation.

  • Fire Proofing and Safety:

Compliance of current fire regulations.
“Smart Ceiling” complies with the current fire regulations with a fire damper for each room like all other ventilation systems.
The fire classification was verified in accordance with EN 13501-1 and certified by classification reports from „MPA Stuttgart” (Notified Body No. 0672).

  • Acoustics and Soundproofing:

To be evaluated from e.g. reverberation time in primary room.
”Smart Ceiling” is the markets’ best metal ceiling
Class B (alpha) w = 0.80
Further acoustics muffling can be mounted over the ceiling. 50% covering is tested by The Danish Technological Institute.

  • Maintenance and cleaning-friendliness of buildings:

To be evaluated from e.g. maintenance grade and cleaning-friendliness.
”Smart Ceiling” consists of no movable parts and needs no maintenance. The system has smooth surfaces and is very cleaning-friendly; with either a vacuum cleaner or a dry or damp cloth. In kitchens, laboratories etc. where standards may be higher, surfaces without perforation should be used.

  • Suitability as regards dismounting and reusability:

To be evaluated from whether the material can be split up and sorted as regards reusability.
All ”Smart Ceiling” parts can be split up and reused.
