DEFINITION
Intelligent buildings are buildings that through their physical design and IT
installations are responsive, flexible and adaptive to changing needs from its
users and the organisations that inhabit the building during it's life time. The
building will supply services for its inhabitants, its administration and operation
& maintenance. The intelligent building will accomplish transparent 'intelligent'
behaviour, have state memory, support human and installation systems
communication, and be equipped with sensors and actuators.

WHAT IS AN INTELLIGENT BUILDING?
A building…
• who’s systems are self-reliant
• with sensors relaying data
• that uses the latest technology
• that is the future of buildings

COMPONENTS OF AN INTELLIGENT BUILDING
Integration of various building systems
– Energy management system
– Lighting management system
– Security systems & fire safety
– Telecommunications & office automation
– Local area networks (LANs)
– Cabling management
– Intelligent maintenance mgt. system (IMMS)
– Computer aided facility management (CAFM)
Four main aspects:
– Facility management
• Take care & maintain various functions for occupant comfort & operation
– Information management
• Office automation (OA), LAN, wiring
– Communication
• Tel/Fax, e-mail, video telecommunication
– Control
• DDC, building automation system
Common needs of intelligent building tenants:
– Built-in Internet wiring
– LAN/WAN connectivity
– Conduits for cabling
– High-tech HVAC
– Wiring for high-speed networks
Critical performance qualities
– Functional or spatial quality
– Thermal quality
– Air quality

– Aural quality
– Visual quality
– Building integrity

NASA and William McDonough + Partners have teamed up to create Earth’s
first high-performance space station. William McDonough stated, “Design is the
first signal of human intention.” With that in mind, the team set out to design a
building that that embodies NASA’s spirit, fosters collaboration, supports health
and well-being, and goes beyond LEED Platinum in its pursuit of Cradle to
Cradle solutions.

The innovative, 50,000 square-foot office building is located at the entrance to
NASA’s Ames Research Center in Moffett Field, California. The most iconic
feature of the building is its structure. Inspired by the wind tunnels of NASA
Ames Campus and the images of NASA satellites, the exoskeleton approach
gives the building increased structural performance during seismic events,
provides a framework for daylighting and shading strategies, and creates a
column-free interior space that facilitates workplace flexibility.

Ground Source Heat Pump:
 106 well bores, 58º F ground temperature year round
 4 heat pumps

Radiant Heating/Cooling:
 Radiant cooling ceiling panels, 40% less energy use than typical VAV
systems
 Hot water radiant wall heating panels
 Natural ventilation with automated windows for flushing during evening
hours

Intelligent, High-Performance Lighting Systems:
 LED fixtures in many areas of the building
 Sophisticated lighting control system automatically dims lights to adjust
for ambient conditions and time of day

Solar Photovoltaic and Thermal Panels:
 432 panels in 24 strings of 9 modules on each building (north and south)
 Photovoltaic panels are designed to generate up to 30% of building
electricity requirements
 Solar thermal panels provide domestic hot water

Bloom’s Energy Server TM Solid Oxide Fuel Cells:
 Solid oxide fuel cell currently utilizes natural gas as fuel; future plan for
methane capture
 Expected electric conversion efficiency 55% (almost twice conventional
power generating plant and grid system efficiency)

The overall water goal is to create a closed loop system that will allow
water that falls on the site to leave at the same rate, volume and cleanliness

of predevelopment conditions. Water fixtures used throughout the building
optimize performance, including quality and quantity of flow and
automated control systems.
Groundwater reduces the demand for potable water. An existing facility to
pump and cleanse contaminated MEW groundwater is located near the
building site. Sustainability Base uses this cleansed water to irrigate the
landscape.
A forward osmosis water recycling system, developed by NASA for use on the
International Space Station, purifies water to drinking quality. Due to
regulations in California limiting use of treated wastewater, it is currently used
to treat gray water from sinks and showers for reuse in toilet and urinal flushing.

Intelligent landscape design includes native and drought-tolerant species
selection, drip irrigation systems and the design of water cleansing
systems. These further reduce water demand and cleanse water that runs
through the site.

The interior of the Sustainability Base actively supports the health and
well-being of all occupants. Large floor to floor windows and narrow
building floor plates provide excellent natural lighting deep into the
interior of the building. Modeling suggests users will only need to use the

building’s electrical lighting 42 days out of the year. Second floor
skylights provide additional natural light, while exterior horizontal and
vertical aluminium shades reduce heat gain and mitigate glare.
Super insulated exterior metal panel system with high performance glazing
provides a tight, warm envelope for cool Bay Area mornings. When the
interior gets too warm, operable windows controlled by users and building
management systems create gentle cross-ventilation. Localized heating or
cooling is provided by radiant panels, allowing for longer periods of
natural ventilation.
A raised access floor throughout the open area allows for user and system
flexibility, and is connected to a dedicated outdoor air system to provide
fresh air distribution when the building’s windows are closed.
The open office floor plan is divided into neighbourhoods of 25-30 people,
linked by common services and aligned along an interior street to provide
team-building and collaboration. Materials were selected using rigorous
criteria for ecological and human health.

Material content considerations included recyclable/recycled materials,
salvaged materials, and locally available and/or rapidly renewable
materials and certified wood. The main components of the design

(concrete, steel, glass, aluminium) had high
recycled content and were regionally available,
thereby reducing transportation energy.
Design for disassembly was facilitated by
choosing a steel structure (rather than concrete)
that can be easily dismantled as well as repaired
after a seismic event. Exterior cladding was
provided in pre-fabricated unitized components.
