… SIGNIFICANTLY CONTRIBUTING TO CLIMATE CHANGE AND RESOURCES

SCARCITY

+2°C by 2100 (COP 21) 60 million in 2015, 250 million by 2050

> 7 million deaths in the world in 2015

+40% by 2030 +40% by 2030

+ 50% by 2030, with some raw materials disappearing by 2100

VISUAL COMFORT: A TRADE-OFF BETWEEN GLARE AND DAYLIGHTING


● New light sensitive cells (related to the circadian cycle) have been identified in the eye about ten years ago

● They are responsible of the Non-Visual Effects, which impact on biological functions such as:

• Sleep/wake regulation

• Alertness

• Mood …

VISUAL COMFORT: NON-VISUAL EFFECTS OF LIGHT

EXAMPLES OF R&D

OUTCOME


LOW-E GLAZING (ENERGY EFFICIENCY AND THERMAL COMFORT)


INNOVATIVE GLAZING

Heat needs

11 kWh/m²y

Heat needs

6 kWh/m²y

House in Vienna with Triple Glazing with SGG PLANITHERM MAX Ug = 0.6 W/m²K and g = 0.60

Wall U=0.12 W/m²K

Solar gains compensate for the difference in thermal insulation

Having more glazing is favorable!


WINDOW FILMS

Typical solar control window film

- Laminate of optically clear PET films

- Functionalization through R2R thin film

sputtering and/or wet coating technologies

- Mounting adhesives

- Acrylic PSA

- Polyester CDA

- UV absorbers

- Laminating adhesive

- UV curable acrylic hard coat


HIGH PERFORMANCE INSULATING PRODUCTS

λ = 5.2 mW/(m.K)

Certified ACERMI

ISOVIP


The Canadian well is a geothermal solution which provides heated air in winter and cooled air in summer. Passive, although coupled to a mechanical ventilation system

ELIXAIR is a complete solution Reduction of energy spendings Natural thermal regulation

◦ Summer Comfort without air conditining ◦ Frost protection in winter

Indoor air quality

CANADIAN WELL (HEAT EXCHANGER)


PRODUCTS AND SYSTEMS FOR THE BUILDING ENVELOPE: MULTI-

MATERIALS AND MULTI-BRANDS


FACADE F4 (ISOVER, PLACO)


DAYLIGHTING: VISUAL COMFORT … ENERGY EFFICIENCY ALSO


VISUAL COMFORT: ACTIVE GLAZING


ELECTROCHROMIC GLAZING: REDUCING HEAT AND GLARE


ACOUSTIC COMFORT – EX FOR OFFICE BUILDINGS

Good sound Insulation: to limit noise coming from neighbors

Good Sound Absorption To ensure speech clarity in the room

SG approach: from the material microstructure to the system performance: Final system: suspended ceilings

with Mineral Wool panel + grid

Ceiling to be

optimized


INDOOR AIR QUALITY

Scavengers in the core of plasterboard to

reduce formaldehyde to inert compounds

•Authorities

•Legislation

•Standards

•Architects

•Designers

•Developers

•Engineers

•Components suppliers

•Builders

•Contractors

•Owners

•Users

From the first stages of the process

• A shared performance target

• Building science

MEASURED

ESTIMATED

PERFORMANCE


SG QUICK U-VALUE OF BUILDINGS

Thermal performance measurements are difficult

(DPE in France; two weeks of co-heating measurement in UK)

Need for a quick and accurate method for intrinsic performance measurement: SG QUB

Evolution scheme of temperature and power

Day 1 Day 2 Sunset Sunrise


SG QUICK U-VALUE OF BUILDINGS, U. SALFORD EXPERIMENT

QUB comparison with static measure in a full-

scale climate chamber

House retroffited by stage

Good agreement whatever is the insulation level


SG QUICK U-VALUE OF BUILDINGS, DECOMPOSING ELEMENTS

Co-heating + ISO 9869-1 (reference) = 14 days

QUB/e = 1 night (heating duration = 7h)
