Plans are being made to establish a Green Building Council
for the UK to unite the sector and create a surge in environmentally
friendly development. It looks likely that the scheme will
be similar to the US Green Building Council which has led
to "remarkable achievements". Dr David Strong, managing director
of the environment division at the Building Research Establishment
(BRE), has taken up the challenge of trying to bring change
to a sometimes stubborn industry. "We're trying to act as
a catalyst," he says.

Green building efforts were presented in force at the 2006
International Builders' Show by plastics manufacturers that
continue to push product breadth and depth to serve the growing
sector. At one booth, Dow Building Products exposed show visitors
to 78DG F in Phoenix and 22DG F in Michigan. It's the insulation
that matters, officials said, showcasing Dow products such
as its Styrofoam Blueguard extruded foam insulation on oriented
strand board, to show how it prevents moisture buildup and
heat loss. "Heat rises, cold falls, you get this thing called
convective looping," explained Tim Lacey, global marketing
director for Dow's Building and Construction group.
- Applying multi-objective genetic algorithms

Since buildings have considerable impacts on the environment,
it has become necessary to pay more attention to environmental
performance in building design. However, it is a difficult
task to find better design alternatives satisfying several
conflicting criteria, especially, economical and environmental
performance. This paper presents a multi-objective optimization
model that could assist designers in green building design.
Variables in the model include those parameters that are usually
determined at the conceptual design stage and that have critical
influence on building performance. Life cycle analysis methodology
is employed to evaluate design alternatives for both economical
and environmental criteria. Life cycle environmental impacts
are evaluated in terms of expanded cumulative exergy consumption,
which is the sum of exergy consumption due to resource inputs
and abatement exergy required to recover the negative impacts
due to waste emissions. A multi-objective genetic algorithm
is employed to find optimal solutions. A case study is presented
and the effectiveness of the approach is demonstrated for
identifying a number of Pareto optimal solutions for green
building design.

Timely engineering feedback to the architect during the design
process can result in improved building performance. Architectural
sketches convey the architect's initial design intentions
and explorations. As such, they become the first means for
communicating with the structural engineer. The goal of this
research project is therefore to provide the structural engineer
with the mechanisms for devising feasible structural solutions
from architectural sketches thus enabling early collaboration.
This project is being carried out in collaboration with the
LUCID group from the University of Lige, in Belgium. The project
combines the strengths of two computer-based prototypes: EsQUIsE
developed by the LUCID group for capturing and interpreting
freehand architectural sketches, and StAr developed by the
authors for assisting engineers during conceptual structural
design. Such early collaboration assistance enables the architect
to assess the structural consequences of his/her designs at
sketching time without interfering with creative work, and
it provides an opportunity for the engineer to get involved
earlier on in the building design process and voice structural
concerns in a timely manner.

Record home heating and energy prices over the winter could
reshape the building and construction market in 2006. BASF
has seen exponential growth over the last three to five years
for its spray-applied PUR because of the higher "R" or insulation
value the foams provide. On the PUR side, the product remains
mostly in the realm of higher-end custom homes, but its air
infiltration barrier and higher insulation value per unit
thickness could push it into further usage. For GE, which
sells specialty film and sheet featuring its Lexan and Ultem
materials into the building and construction market, energy
efficiency initiatives point consumers towards products like
its solar control IR sheets that have 25-40% energy savings
over traditional glass-type materials. Moving beyond coatings
for glass, the multilayer films and sheets are being formed
into actual structural components.

High Performance "sustainable" or "green" buildings are emerging
as an important market in the United States and around the
world. The increased demand for high performance buildings
has simultaneously created an opportunity to rethink the design
process. To optimize the design process for high performance
buildings, a project management environment that unites architects,
engineers, and builders must be created and key design processes
and competencies of design teams must be defined. This paper
presents the initial results of an effort to model the process
and discipline requirements for the design of high performance
buildings. The Building Design Process Model for High Performance
Buildings (BDPMHP) and the accompanying Cross-Functional Design
Process Map for High Performance Buildings (CFDPMHP) are presented
as mechanisms to assist in the transformation of traditional
design processes. Background and design development models
of the BDPMHP and CFDPMHP are presented and testing of the
BDPMHP through case study analysis and virtual design team
simulations is described. Emerging patterns and key processes
on successful high-performance building projects are identified.
This research benefits facility owners by identifying key
attributes of a high performance design process that decrease
design process waste and reduce the first-cost of high performance
projects.

Many in the building construction industry, including architects,
building owners, and even structural engineers, fail to appreciate
the significant contribution the structural engineer can make
to reducing the environmental impact of a building construction
project. This lack of understanding is one of the chief impediments
to achieving the greatest possible reduction in the environmental
impact of the structural system. Structural engineers interested
in sustainability must combat this ignorance by educating
themselves and others so that they will be brought into the
circle of sustainability decision-makers and be able to make
their contribution to reducing the project's environmental
impact.
- China's First "Green" Building
Anonymous
Elevator World, Vol. 52, No. 9, Sept. 2004, pp. 40.
The Beijing Ministry of Science and Technology's new headquarters
has been designated as a "green building," the country's first.
The building was designed using the U.S. Department of Energy's
Leadership in Energy and Environmental Design (LEED)TM Green
Building Rating System. Johnson Controls, Inc., based in Milwaukee,
Wisconsin, installed the building's automation system with
Metasys(Registered)software, which controls the elevators,
heating, ventilating, air-conditioning, lighting and electrical
systems. The floor area of the new headquarters is 19,000
square meters to include nine floors of office space. One
of the energy-saving features includes fresh air and air-handling
units controlled by a frequency converter providing air volume
on each individual floor according to its specific needs.
The fresh air can even be preheated for winter temperature
adjustment. This project is considered a pilot to showcase
the efficiency of energy-saving technology, an important consideration
since the World Bank has estimated that nearly half of all
building construction over the next two decades will be built
in China.

A frequent point of debate is the relationship between Green
Building and Sustainable Development (SD). We take the view
that SD is most applicable at the urban or societal level,
since it includes issues of social equity and broad issues
of economics, in addition to concerns about ecosystems and
human health. It is difficult to apply these broader societal
issues to buildings in a practical way and instead, many building
researchers and designers find it more meaningful to develop
models of building performance that is consistent with SD
at the societal level. In short, Green Building helps to support
a broader Sustainable Development agenda. If Sustainable Development
goals are to be truly reached, we could argue that buildings
should consume no energy, water or materials, and should produce
no emissions, noise or waste over their lifespans. While this
is an interesting concept, it is likely that we will have
to work towards more modest goals during the next 20 years.
Even at a more realistic level, there is global interest in
improving the performance of buildings. Governments want to
reduce the use of scarce resources and airborne emissions,
owners want to reduce operating costs, and developers are
finding that customers are demanding higher quality and performance.
l Although the achievement of this goal in different countries
will require varied strategies, it is certain that all will
have to make substantial improvements in the methods used
to design, construct and operate buildings. This will require
interventions by governments, but it will also require that
designers adopt a different way of working. The building industry
is very different from other sectors with substantial environmental
impacts. The performance of automobiles, for example, can
be improved by working with relatively few manufacturers,
but the construction industry consists of thousands of organization,
ranging from very small to very large, and staffed by individuals
whose levels of skills and training vary from very basic to
quite advanced. Buildings are also long-lived compared to
other products, and have to conform to local cultural and
climatic conditions in addition to meeting functional requirements.
All of this implies that initiatives for performance improvement
must be addressed on a broad front. This paper will confine
itself to the range of initiatives that look promising in
the large buildings sector (excluding small houses) and within
market economies. In addition, the discussion will be focused
on measures that apply primarily to the design and construction
stages, for both new and renovated buildings. All the approaches
discussed are based on Canadian experience, but their basic
strategies are of broader interest.
