Meta Issues

To create a path from being environmentally effective through sustainability to engage the built environment in a “restorative activity” (term from Bill Reed)

Is the present state of our natural system “good enough”?



Buildings as an integral part of a living system and positively co-evolving to continuously improve:

SunWater

AirSoil Resources

Of our Planetary System


This means….• Moving away from a totally human-centric view of

the world,• Understanding the synergism between nature and

human nature,• Appreciating the interconnectedness of the whole,• Using principles of living systems to approach our

work• Seeing ourselves as continual learners and

avoiding hubris,• Encouraging dialogue and asking deeper questions,

and • Recognizing the role of spirit and love in everything

we do.


Financing, designing, engineering, constructing, operating, and managing buildings that grow out of and reflect the characteristics

and conditions of their place, and are integral, value-adding members of the living systems of which they are a part.

This requires wholistic systems thinking/integration, methods, practices,

•Natural

•Human-social

Economic

Policy

Ethical


This means….• Access to nature linking indoor and outdoor rooms in

layers of environmental diversity, Regionalism with inspired responses to climate and culture,

• Passive conditioning and innovation to celebrate the affordable abundance of nature for daylighting, ventilation, creating color, dynamics, free warmth, free cooling.

• Ecological land-use and ‘whole life’ pedestrian neighborhoods supported by light rail and high speed rail communities of culture and commerce,

• A balance off integrated, robust and flexible infrastructures and timeless, highly crafted places,

• Shift from esoteric and ionic ‘sculpi-tecture’ to celebrations of nature and humanity.

WHOLISTIC VALUE PROPOSITION

The shared base for decision making:

Financier, Client-User-Occupant, Designer/Engineer,

Eco-system Community

SERVICES: Continuous monitoring of : 1) Human Comfort-thermal, visual, acoustic, spatial ergonomic, air quality 2) Human occupancy

patterns 3) Functional requirements 4) Building operations regarding energy, water, air, and soil


Financing, Design, Engineering and Commissioning

All Stake holders, including policy-community-owner/occupant-facilities management-construction-key technologie(s) providers-representatives are integrated from early design/engineering stage in a team with financier/architect/engineering owner team.


Assisted by• Integrated building information models (BIM)

which are inter-operable (e.g., IFC compliant). Such models should support the “life cycle” processes of the building from conceptual design (e.g., building performance analyses) to building operations (e.g., operational controls and diagnostics)

• Supply chain management techniques/processes

• Analyzed best practices


Assisted by the existence of

• Plug & Play high performance enclosure sub-systems that balance exterior climate and weather forces with interior occupant and functional requirements to beneficially use daylighting, material ventilation passive heating and cooling, as well s generate energy (PV, solar thermal); harvest and purify water and regenerate soil

• Modularized and pre-fabricated structural and interior components and subsystems to provide for flexibility, adaptability and closed-cycle material flows (up-cycling in industrial or agricultural nutrient streams (Michael Braungart))


• Plug & Play highly integrated, fabricated, packaged and miniaturized distributed, multi-modal energy generation, conversion and conditioning subsystems.

• Plug & Play sensing, actuating and control subsystems to operate the whole system (enclosure, energy, HVAC, lighting, etc.) effectively (user comfort, environment, energy, and water).

• Plug & Play diagnostic systems (integrated with above) utilizing building performance modeling based on scientific (physics, biology, chemistry) and engineering principles.


Operation, Long Term Maintenance, and Continuous Commissioning

• Integrated transdisciplinary service contracting supported by advanced sensing, actuating and control technology with automated data storage, communication mining and meaningful reporting to continuously

• Assessing the system’s performance vis à vis – Human comfort/productivity, ecological,

environmental effectiveness (sun, water, air, soil), energy, economics.


• Diagnosing the systems requirements for maintenance, adjustments, and repair (preventative).

• Integrated long-term learning from the actual performance -in the field- of the advanced, fabricated plug & play materials, components, subsystems, and systems to inform the entire industry and enable collective competence in “restorative practices”.


Examples of Breakthrough Technologies from the HCII

• Integrating and packaging multiple appropriate sensors with local intelligent and networking capability to measure indoor environmental parameters

• Developing methods to engineer a system of personalized environmental monitoring sensors that are user transparent, ergonomically wearable objects.

• Developing a system of communication to integrate the sensors into existing building information systems, architectural features, and engineered building components and systems.

• Developing a system of algorithms for decision-making on collected information.
