THE ULTIMATE CONSTRUCTION METHOD FOR AFFORDABLE GREEN BUILDING
By Tony Mainsbridge
As an advocate of the Green Building concept, I am often amazed by the attitude of
Builders, Designers, Engineers and Specifiers who continue to ignore the magnitude of
Advanced Framing Techniques as one of the single most significant aspects of
construction related Environmental Responsibility.
The ultimate paradigm of the Advanced Framing Technique, (a.k.a: Optimum Value
Engineering or O.V.E.), encompasses the absolute definition of Resource Efficiency as
an essential element of Green Building in the context of wood framed residential
construction, as well as comprehensively enhancing both Energy Efficiency and
WOOD – RENEWABLE, SUSTAINABLE, USER FRIENDLY - OUR BEST RESOURCE
Dimension Lumber (2x4’s, 2x6’s, etc) and Wood Structural Panels (Plywood) are the most
common materials used in the construction of all structural elements above the foundation
of residential buildings up to three stories in height, and have been for generations.
The advent of both OSB (Oriented Strand Board) and EWP (Engineered Wood Products),
with the focus of their design and manufacture on minimal use of wood fiber for optimum
strength; have provided additional ways to build while conserving resources.
Building Materials manufactured from wood, a Renewable raw material, have a minimal
impact on the environment, with exception to the fact that trees – the raw materials –
serve a more momentous role in the realm of Environmental Protection and
Preservation. Trees, as a living organism, convert carbon dioxide - one of the most
abundant and pervasive ozone depleting gases - to oxygen through photosynthesis.
This FACT alone should make us all want to conserve as much lumber as possible!
THE FRAME – HOLDING THE HOUSE UP AND HOLDING THE HOUSE DOWN
The design loads of a structure
include the DL (dead load) and
LL (live load) which are the loads
that must be held up, and the
