||Buildings Committee Reports on ISO
Performance and return on investment (ROI) have always been critical
measures for building systems such as HVAC and lighting. Increasingly,
performance and ROI are becoming critical quality issues for every
product that goes into a building, said Dru Meadows, an architect
with The Green Team, Inc., Tulsa, Okla. This is true domesticallyand
internationally, affirmed Meadows, who chairs the U.S. Technical
Advisory Group (TAG) to International Organization for Standardization
(ISO) Technical Committee 59/SC14, that is managed by ASTM.
Building materials manufacturers who reference ISO standards
should become aware of the activities of a subcommittee of the
TC59 on Building Construction known as SC14 on Design Life, said
Meadows. SC14 is addressing the service life or the maintenance
and durability of construction products as they apply to the intended
function of a building. Standards developed under TC59/SC14 can
have a large impact on the competitiveness of various building
materials in the global market, she added.
Participation from U.S. manufacturers is sorely needed, as only
five members of ASTM Committee E06 on Performance of Buildings represent the total U.S. building-product
interests in the international arena as a U.S. TAG to ISO. Since
the first meeting of SC14 in Gavle, Sweden, June 1998, there has
been a great deal of progress made towards development of Buildings
and Constructed Assets: Service Life Planning standards continued
Meadows. Unfortunately, much of this development has occurred
with very little input from the USA. Additional U.S. TAG members
are needed to ensure that U.S. interests are properly represented
in this effort.
The implementation of service life planning into the thinking
of building designers and lending agencies has the potential to
dramatically alter the way buildings are constructed and the way
land is developed, said John Mulder, technical services manager,
James Hardie Building Products, Fontana, Calif., a member of the
U.S. TAG to ISO TC59/SC 14, and first vice chair of ASTM E06.
Specializing in building materials and active at ISO meetings,
Mulder described the potential impact of ISO SC14 standards on
international building construction: As regulatory agencies and
public opinion impact more in the realm of personal and natural
environmental protection, the types of buildings, the materials
that are permitted in the construction of the buildings, the energy
resources expended to construct and support the buildings, and
the long-term use and disposition of the land, building materials,
environmental impact, and subsequent reuse and/or landfill consequences
will need to be addressed.
Mulder reported the status of the following ISO SC14 draft standards:
Part 1, General Principles, FDIS 15686-1: After major revisions,
this document has been balloted as a draft international standard.
ISO is awaiting member country ballot results.
Part 2, Service Life Prediction Procedures, CD 15686-2, is being
Part 3, Performance Audit and Review, CD 15686-3: Substantive
revisions have been made to the committee draft that is currently
Part 4, Service Life Prediction Data Requirements, CD 15686-4:
This document needs extensive work by working group members. There
is not agreement on the format and audience, and the method(s)
of calculating the predicted service life. Two methods currently
on the table for discussion are: (1) predicted service life calculated
by the factorial method with values provided by researchers, and
(2) in-service durability values provided by industry. Input
on the U.S. experience, with examples of successful implementation,
would help the U.S. TAG to resolve this issue.
Part 5, Maintenance and Life Cycle Costing, CD 15686-5: This
working group is struggling with key performance indicators
related to service life planning and whole life costing. There
is a difference in the strategy of assessment and analysis from
country to country. Input on the U.S. experience, with examples
of successful implementation, is invited.
