CHALLENGE US..



VENLO ASKED FOR A BUILDING WITH A POSITIVE IMPACT..



NOW THEIR BUILDING PURIFIES THE AIR AND WATER AND ABOVE ALL IT GENERATES ENERGY.



CITY OFFICIALS IN VENLO NOW WORK IN AN OFFICE 5X HEALTHIER THAN AVERAGE.



“I WANT TO MAKE MY PRIVATE ART COLLECTION MORE ACCESSIBLE TO THE PEOPLE”



VOORLINDEN IS NOW HOLLANDS MOST VISITED PRIVATE MUSEUM.



“WE WANT TECH-STUDENTS TO BROADEN THEIR HORIZON”



@ THE PLAYGROUND TECH-STUDENTS NOW EXPLORE ARTS, SPORTS, CULTURE AND TECHNOLOGY IN A HYPERFLEXIBLE BUILDING

CIC CHOSE US TO DESIGN THEIR ECOSYSTEM FOR INNOVATION

AFTER ONE YEAR A 100+ START-UPS GATHERED THERE IN ROTTERDAM.

“WE NEED 67.000M² OF OFFICE, BUT OUR PLOT IS WAY TO SMALL”

NOW 5000 PEOPLE WORK ON TOP OF THE BUSSIEST PUBLIC TRANSPORT HUB OF THE NETHERLANDS.

CAN WE WALK ON AIR?

YES WE CAN!

AIR PURIFYING BUILDING


Air purifying building


Air purifying buildingIf a car can purify the air why can’t a building do the same?


Air purifying buildingBuilding facade as a green lung

Solar Chimneys for natural air flow.Greenhouse in wintertime air flows through

the greenhouse to the AC, in summertime it

goes directly to the AC, trees purify the air.

North-eastern Green Façade air

purifying, insulating, filters out particulate

matter, NOx and SO

3. Air comes out

cleaner than it goes in

Square with trees to filter the air and

dampen noise and wind.Constructed Wetland Roof

for water filtration.

Parking Garage precools the air in summertime.


TU/e test results

30 % SO2 decrease

30 % NOx decrease

with lower airspeed:

50 % less?

the green facade

compensates for 3000 m2

road in dust (smog)

(royal haskoning)

Air purifying buildingBuilding facade as a green lung

Results from tests with

the facade at

TU Eindhoven:

30% decrease in SO2

30% decrease in NOx

At lower airspeeds 50% reduction could be possible

The green facade compensates the emission of fine dust particles genereated bij the equivalent of 3000 m² road


Air purifying buildingLow tech, high impact

MATERIALS AND HEALTH


Materials & HealthEye catching stairs increases activity during the day


Materials & HealthThe green facade cleans the air, inside and out.


Materials & HealthThe Office floors are open and filled with daylight


Materials & HealthThe Office floors offer a variety of workstations

ZERO ENERGY


Zero EnergyPV panels, an abundance of daylight, led-lights and overall energy efficiency


Zero Energy“We want active buildings!” Michel Weijers, City of Venlo

CLOSED WATER LOOP


Closed Water Loop

Collect rainwater

Water saving taps and toilets

Separate grey water system

Constructed wetland cleans water for nonfood reuse

Solar collectors

Energy efficient kitchen equipment


Closed Water LoopConstructed Wetland Roof

BUSINESS CASE


Business caseTotal Cost of Ownership vs. Total Cost of Usage

TCO VS. TCUInitial investments + operational costs

Health + productivity

Residual value:

The building as a deposit for raw materials.

Business case Health + productivity

In a healthy building everybody profits

• 1% drop in sick leave is a € 600.000 saving for the

city of Venlo. Per year!

• Constant monitoring air quality and wellbeing.

• Scientific field research by University of Berkeley,

Maastricht en Aachen.
