Architecture 2030 continues its dialogue with professional organizations and government
at all levels in an effort to implement the targets outlined in the “2030 Challenge”. The
Architecture 2030 message will be delivered in a keynote speech by Edward Mazria at the U.S.
Conference of Mayor’s Emergency Summit on Energy and the Environment, May 11, 2006
in Chicago. At the summit, a letter from the president of the American Institute of Architects,
Katherine Schwennsen, will be delivered urging mayors to adopt the 2030 targets. Also, a
resolution calling for cities to adopt the “2030 Challenge” for all city funded buildings has been
introduced to the US Conference of Mayors (USCM) by Albuquerque’s Mayor Martin J. Chavez,
Chicago’s Mayor Richard M. Daley, and Miami’s Mayor Manny Diaz. The USCM will vote on the
resolution during its upcoming Las Vegas meeting June 2-6. |

A HISTORIC MOMENT June 2, 2005, Scripps Institute of Oceanography, “Scripps-led Global Ocean Warming Research Paper Published in Science”.The “2030 Challenge” clearly outlines a global strategy to immediately stabilize and begin reducing building sector GHG emissions, with the goal of realizing a 60% to 80% reduction below today’s level by 2050. What makes this strategy unique is that it is mostly achievable through design, through creative problem solving and the application of information and innovation, the very elements that are the foundation of the design professions. There is no short-term or long-term GHG reduction solution possible without involving the global design community. To date, this community has not been invited to participate in meetings, policy setting sessions or UN and IPCC (Intergovernmental Panel on Climate Change) gatherings regarding climate change. This illustrates that the scientific community, government and general public do not really understand what architects, planners and designers do and how central their role is in crafting meaningful mitigation strategies. With time running short, and abrupt rather than gradual climate change looming as a distinct possibility, the design community must be quickly engaged. The Telenor Headquarters Complex by NBBJ  The Telenor Headquarters
Complex is framed by two openended
and over-lapping curved
boulevards that define a central
plaza. Four office wings connect to
each boulevard at clearly defined
circulation nodes. The design of
this project was inspired by its
site and takes full advantage of its
natural surroundings. The Building
is a metaphor that references both
the former airport (on which this
building is sited) and the ships/sails
on the Oslo fjord. The design also
articulates the new wireless contacts
of a global information technology
center.High Performance Design: Telenor reports that the building’s energy consumption, per employee, is about half of what it was in its older facilities. Consumption was 14,000 kilowatt-hours per person per year in the old buildings and 7,000 kilowatt-hours per person per year in its new headquarters. The following strategies contribute to the buildings energy performance: Passive Solar and daylight: The overall layout and design of the 2 million square feet office complex maximizes the envelope surface for natural ventilation and for daylight to reduce energy consumption caused by cooling loads and artificial lighting. As part of the passive solar heating strategy, the building on the south side is 2 stories shorter than the building on the north (the north building is 5 stories while the south building is only 3 stories) letting the low winter sun reach the entire glazed facade of the north building. An advanced double exterior skin was used for 15 % of the building’s curtain walls, with the space between the glazing incorporating the flow of warm air in winter and cool air in summer. The double skin also allows for regulated natural ventilation and daylighting, as well as noise control. Mechanically operated exterior sunshades reduce solar gain in summer and electronic photo cells/sensors control glare when the sun is too intense. Atrium spaces between office wings are designed to capture direct sunlight in winter and provide for daylight to adjacent offices throughout the year. Daylight reaches almost all corners of the building and floor plates are never more than 15 meters deep. No work place is located more than 9 meters from an exterior glass wall to provide daylight and views for all staff. Operable windows allow for natural ventilation when the weather permits.  “Comfort cooling” with chilled ceilings:  The design of the mechanical cooling and
heating systems take advantage of the
building’s waterfront location. Cool water is
circulated through ventilation ducts as well
as in each building’s ceiling elements. Warm
water leaves the building and is re-cooled
via a heat-exchange system that utilizes cold
water from the nearby North Sea/Oslo fjord.
This system provides 80% of the building’s
heating and cooling needs.The heat pump is powered mainly by water from the North Sea. Water is heated using electricity, and its steam is compressed to to become a high-pressure vapor that eventually travels through the building’s radiators. Automation System: The innovative cooling and heating systems precipitated the development of a complete building automation system (BAS). The building’s major systems - HVAC, lighting, electricity, conveyance - are connected together digitally by a centralized energy management system (EMS). The electronic devices that run the building’s system speak a digital language called LON (for Local Operating Network). LON allows these devices to be configured for maximum efficiency, share data and communicate with each other. The HVAC system powers down when the building - or portions of it - are unoccupied. The lighting system is also “scenario controlled”, meaning lights are adjusted automatically when sunlight levels changes or when people enter or exit. With this system one does not use more energy than one actually needs.
