Biomass Thermal & LEED
Introduction BTEC
Introduction to BTEC
The Biomass Thermal Energy Council (BTEC) is the industry trade
association dedicated to advancing the use of biomass for heat and
other thermal energy applications.
Why was BTEC established?
1. To advocate for and promote the industry in the national energy policy debate
2. To reach out to and educate the public and decision makers on the benefits
and advantages of using biomass for heat
3. To develop biomass energy research and analysis that enables sound
investment and policy decisions

Project made possible by the USDA FS WERC
{ BTEC awarded a grant from the USDA Forest Service’s Wood
Education and Resource Center (WERC) in June 2011
{ BTEC and Resource Professionals Group are developing tools to
help HVAC professionals, wood energy equipment manufacturers,
and other stakeholders interact and address the challenges and
opportunities in specifying biomass-fueled equipment in the
commercial buildings sector.
{ The Center's mission is to work with the forest products industry
toward sustainable forest p
products p
production for the eastern
hardwood forest region.
{ All questions and attendee feedback will help form future activities.

EA Credit 2 – Eligibility as “On-Site” system
Reference Guide Addenda ID #10001081
• Fuel source wholly contained/produced on-site; (OR)
• Building owner demonstrates full ownership of the fuel
source including ownership of all its environmental
source,
attributes; (OR)
• Projects must enter into a 2-year contract for purchase
of the renewable
rene able ffuel
el so
source,
rce with
ith an ongoing
commitment to renew for a period of 10 years total.
Note: directed purchase of biofuels does not apply,
since the renewable fuel is not used within the project
EA Credit 2 – Relevant Interpretations
• ID #2591: Wood meeting the following criteria may be
counted as site-generated renewable:
• Wood waste harvested on-site
on site from maintenance and
construction clearing operations
• Wood harvested from a sustainably managed and
sourced forest that is contiguous to the project site and
has the same owner
• ID # 5332:
• Wood associated with maintenance operations that is
h
harvested
t d from
f
a site

tto th
the project
j t site
it andd
has the same owner may be counted as “renewable”
EA Credit 2 – Examples of Biofuels in EA Credit 2
• Wood pellets created from wood mill residue in local wood
mill.
mill
• Project ownership develops two-year contract with wood mill with
commitment to extend for ten years.
• Contract includes terminology that confirms wood pellets will be
solely sourced from wood mill waste, and the environmental
attributes will be retained byy the buildingg owner
• Local community college develops 10-year contract with
nearby dump to receive landfill gas refined to natural gas
standards, that representing100% of their annual natural
gas . Natural gas is directly piped to the project site.
On-site Renewable Energy – LEED v4
• No major changes relevant to eligible biofuels
• Only 3 points available for renewable energy production
• Shared community systems allowed with the following
constraints:
• Project owns the system or has a signed lease
agreement for a period of at least 10 years
• System is located within the same utility service area as
