1 SKIN GAMES the Epic Battle of Appearance versus Performance in Facade System Design and Delivery São Paulo 28 November 2018

2 Schueco is an international provider of aluminum window, door and facade systems. 32 locations 4800 employees worldwide Active in over countries 80 SCHÜCO BRASIL; Tel.: ;

3 OUR FOCUS IS THE BUILDING SKIN COMCAST TOWER PHILADELPHIA

4 RELEVANCE The building skin combines considerations of performance and appearance like nothing else in architecture.

5 0% 9of our time is spent in buildings November ALUMINIUM 2016 Conference

6 FACADE ZONE The building skin is the nexus of myriad often competing performance considerations.

7 FACADE ZONE MULTI-FUNCTIONAL FACADE SYSTEMS: BUILDING SKIN as the NEXUS of (often competing) PERFORMANCE CONSIDERATIONS security solar thermal durability daylighting condensation INTEGRATION insulation appearance commissioning air infiltration resilience H2O penetration acoustical recycling ventilation glare environmental impact FACADE ZONE

8 TRANSITION The pathway to sustainable buildings and urban habitat winds through the building skin.

9 out with the old today s facade technology is not what it was 5 years or even 3 years ago MILLENIUM TOWER SAN FRANCISCO

10 TREND ASSESSMENT dominant TRENDS today in building skin technology geometric complexity material and process diversity acoustical performance shading strategies + dynamics

11 TREND TRAJECTORIES thin skins: how much technology can be packed into 25mm? thick skins: layered functionality with spatial separation

12

13 DEEP TRENDS VR AR tools & technology AI + robotics

14

15 MATERIAL & PRODUCT TRENDS Advanced Glazings coatings (low-e on the #10 surface) triple-quadruple glazing X-chromic vacuum glazing vision PV BIPV Silicone Curtainwall assemblies: developments in framing systems A growing diversity of materials in the building skin.

16 PROCESS TRENDS LIFECYCLE: LCA - LCCA DIGITIZATION... of design, fabrication and installation processes

17 DIGITAL TOOLS easily generated complex form not so easily fabricated and erected complexity has a knockon effect

18 Schüco Parametric Facade System

19 Schüco Parametric Facade System there is a strong resistance to system-imposed constraints in architecture

20 FACE CHANGE

21 FACE CHANGE innovation and rapid evolution in building skin technology

22 West 57th St New York, NY

23 West 57th St New York, NY study of geometrical characteristics of sloped wall system to estimate the warpage for structural framing and galvanized back pans, as well as the stainless steel cladding panels images depict initial geometry and subsequent subdivisions to create individual unit and panel discretization Less than 1/4 over the length of the panel Less than 1/2 over the length of the panel Less than 1 over the length of the panel Less than 2 over the length of the panel Less than 3 over the length of the panel Less than 4 over the length of the panel

24 GSA Federal Office Building Miramar, FL

25 GSA Federal Office Building perforated sunscreens control solar heat gain

26 faceted surfaces and ceramic fritting to prevent bird collisions

27 New Stanford Hospital Stanford, CA BMS sensors controllers lighting blinds mechanical plumbing pressurized double skin facade software COMPLEXITY!

28 SUPERTALL SKYSCRAPERS 300+ meters 100 as of 2016 Gran Torre 64 stories

29 MEGATALL SKYSCRAPERS +600 meters at least 7 built, under construction, or in development

30 SKYSCRAPER the movie...

31 TREND ASSESSMENT pursuit of the ICONIC... How sustainable is that! And what does it mean when you have a city full of icons (NYC)?

32 TREND ASSESSMENT Appearance... not performance continues to drive design. This must change, and that change will be TRANSFORMATIVE.

33 TREND ASSESSMENT result: step-change in COMPLEXITY...of facade program implementation

34 34 GLASS COMPLEXITY TYPES LA LIVE TOWER 11 + RESIDENCES WALL TYPES

35 SUSTAINABILITY Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. -Our Common Future, the Brundtland Report

36 CARBON Anthropogenic climate change threatens civilization as we know it, and the very survival of humanity.

37 THE CARBON PROBLEM Buildings consume more energy than any other sector. 76% of building energy comes from fossil fuels. Building energy use is growing faster than any other sector. The building sector produces 47% of all green house gases.

38 INNOVATION A new idea, process or product; a new and different way forward.

39 Innovation as Change Agent

40 You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete. - R Buckminster Fuller The current need lies beyond incremental change...

41 the 5-Cs Five Cs (catalysts) to drive innovation. Use the 5-Cs to shape project design goals.

42 5-Cs 1. Culture (think local) 2. Climate (think micro & macro) 3. Comfort (think health, wellness & productivity) 4. Carbon (think neutrality) 5. Context (think lifecycle) Abandon vested interests. Embrace constraints!

43 Why do buildings (and their facade systems) die? It's not degradation, it's obsolescence; a failure to adapt.

44 Curtainwall system designs fail to anticipate the need for future maintenance, repair and retrofit to prevent obsolescence.

45 CONSIDER THE (DIS)-ABILITIES that shorten service life and amplify lifecycle carbon footprint... durability (+differential)...of systems, components and materials adaptability...to new technology, future loads, and changing conditions of use repairability...to treat damage and degradation

46 CONSIDER THE (DIS)-ABILITIES that shorten service life and amplify lifecycle carbon footprint... maintainability...ease of maintenance to maximize service life upgradability...as an antidote to functional/technical obsolescence recyclability...reuse and minimization of solid waste

47 MATERIAL & PRODUCT TRENDS Advanced Glazings coatings (low-e on the #10 surface) triple-quadruple glazing X-chromic vacuum glazing vision PV BIPV Silicone Curtainwall assemblies: developments in framing systems A growing diversity of materials in the building skin.

48 MATERIAL & PRODUCT TRENDS Advanced Glazings coatings (low-e on the #10 surface) triple-quadruple glazing X-chromic vacuum glazing vision PV BIPV Silicone Curtainwall assemblies: developments in framing systems WHAT ABOUT DURABILITY A growing diversity of materials in the building skin.

49 CONSIDER THE IGU collapsed durability of assembly highly durable - indefinite service life

50 IS GLASS GREEN? not once we get done with it! We take the raw float, make the IGU, collapse the durability from 100s of years to years, make it not recyclable in the process, and call it high-performance glazing!

51 NEXT Embrace the constraints.

52 THE MILLENNIUM IGU Preservation through a planned process of continuous renewal (versus heroic restoration). Section - Millennial IGU low-e film mounted in removeable spacer cartridge annealed or HS glass cassette frame facilitates installation and removal in curtainwall module filters dirt & moisture? material? area required? frequency of replacement? pressure equalizes cavity prevents pillowing replaceable filter cartridge Explore durability and the potential for maintenance and partial renovation cycles to extend service life and minimize embodied energy and carbon impacts using LCA techniques. Develop concepts for highly durable curtainwall systems and components.
