TREND ASSESSMENTdominant TRENDS today in building skin technology

• geometric complexity• material and process diversity• acoustical performance• shading strategies + dynamics

TREND TRAJECTORIES

• thin skins: how much technology can be packed into 25mm?

• thick skins: layered functionality with spatial separation

DEEP TRENDS

• VR – AR tools & technology• AI + robotics

Advanced Glazings• coatings (low-e on the #10 surface)• triple-quadruple glazing• X-chromic• vacuum glazing• vision PV

BIPVSiliconeCurtainwall assemblies: developments in framing systems

A growing diversity of materials in the building skin.

MATERIAL & PRODUCT TRENDS

PROCESS TRENDS

• LIFECYCLE: LCA - LCCA• DIGITIZATION... of design, fabrication and installation processes

DIGITAL TOOLS• easily generated

Sloped Panel Wall

Wall Type 1

Analysis

Utilizing our inhouse software developmentcapabilities, we were able to custom tailora set of procedures to study geometricalcharacteristics of the sloped wall system.

The images to the right are a sampling ofthese analysis. It estimates the warpage forthe structural framing and galvanized backpans as well as the stainless steel claddingpanels. They depict initial geometry andthe subsequent subdivisions to createindividual unit and panel discretization.It is our intent to use these tool to furtheroptimize the final geometry to establish amore robust and economical solution to thepanel system.

TREND ASSESSMENT

• pursuit of the ICONIC...

How sustainable is that!

And what does it mean when you have a city full of icons (NYC)?

TREND ASSESSMENT

• Appearance...—not performance—continues to drive design. This must change, and that change will be TRANSFORMATIVE.

ability of future generations to meet their own needs.-Our Common Future, the Brundtland Report

CARBONAnthropogenic climate change

threatens civilization as we know it, and the very survival of humanity.

• Buildings consume more energythan any other sector.

• 76% of building energy comes fromfossil fuels.

• Building energy use is growingfaster than any other sector.

• The building sector produces 47%of all green house gases.

INNOVATIONA new idea, process or product; a new

and different way forward.

Innovationas

Change Agent

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...

the 5-CsFive Cs (catalysts) to drive innovation. Use

the 5-Cs to shape project design goals.

5-Cs1. 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!

Why do buildings(and their facade systems)

die?It's not degradation,it's obsolescence;a failure to adapt.

Curtainwall system designs fail to anticipate the need for future maintenance,

repair and retrofit to prevent obsolescence.

CONSIDER THE (DIS)-ABILITIESthat shorten service life and amplify lifecycle carbon footprint...durability (+differential)

...of systems, components and materialsadaptability ...to new technology, future loads, and changing conditions of userepairability ...to treat damage and degradation

CONSIDER THE (DIS)-ABILITIESthat shorten service life and amplify lifecycle carbon footprint...maintainability ...ease of maintenance to maximize service lifeupgradability ...as an antidote to functional/technical obsolescencerecyclability ...reuse and minimization of solid waste

A growing diversity of materials in the building skin.WHAT ABOUT

DURABILITY


CONSIDER THE IGUcollapsed durability of assembly

highly durable - indefinite service life

• We take the raw float,

• make the IGU,

• collapse the durability from 100s of years to 20-30 years,

• make it not recyclable in the process,

• and call it high-performance glazing!

IS GLASS GREEN?not once we get done with it!

v

NEXTEmbrace the constraints.

• Preservation through a planned process of continuous renewal (versus heroic restoration).

• 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.
