Trees and Energy Savings

I recently started a discussion on the NPSINFO listserv regarding the link between air
quality (not just greenhouse gas emissions, but also particulates), energy (which is
mostly still generated from dirty sources like coal and nuclear power) and stormwater
and got this great link on urban forests and climate change.

 consume gasoline and diesel fuels.

This is a link to the modeling software described below that, in addition to modeling
GHG sequestration, can calculate the energy savings for trees that are strategically
placed on the site.

The Center for Urban Forest Research Tree Carbon Calculator (CTCC)

The CUFR Tree Carbon Calculator is the only tool approved by the California Climate
Action Registry's Urban Forest Project Reporting Protocol for quantifying carbon
dioxide sequestration from GHG tree planting projects.


The CTCC is programmed in an Excel spreadsheet and provides carbon-related
information for a single tree located in one of sixteen United States climate
zones. Once the ctcc screen shot user enters information on the climate region
and tree's size or age the CTCC produces information on:

* Carbon dioxide stored in the tree due to its growth over many years

* Carbon dioxide sequestered during the past year

* Dry weight of aboveground biomass that could be utilized if the tree was removed


If trees are strategically located to shade buildings and reduce energy consumed
for heating and cooling, additional inputs are required. CTCC outputs include:

* Annual energy savings in kWh of electricity and MBtu of heating per tree

* Carbon dioxide equivalents of these energy savings

* The CTCC can be used to estimate GHG benefits for an existing tree or to forecast
 future benefits for a planting project.

Tree size and growth data are developed from samples of about 650-1000 street trees
 representing approximately 20 predominant species in each of the sixteen regional
reference cities. Biomass equations, many derived from volumetric measurements of
open-grown city trees, are used to derive total

CO2 stored and sequestered. To determine effects of tree shade on building energy
performance, over 12,000 simulations were conducted for each reference city using
different combinations of tree sizes, locations, and building vintages.

Users should recognize that conditions vary within regions, and data from the CTCC
may not accurately reflect their rate of tree growth, microclimate, or building
characteristics. When conditions are different it may be necessary to apply biomass
equations manually using adjusted tree growth data and perform building energy
simulations with modified weather and tree data to more accurately depict effects of
trees on GHGs.

The CTCC is intended as "proof of concept" software that is in the testing phase. It
is provided "as is" without warranty of any kind. In 2011, this version will be replaced
by a Web-based version with greater functionality.

The Future of Green Buildings: An Aggressive Focus on Measurable Performance

Print PDF

Next week, USGBC’s newly announced Building Performance Initiative will be in
full swing with the first of five summits planned to raise the level of discussion
about how we can ensure that all green buildings perform the way they are intended
and that our entire building stock – new and existing buildings alike – is upgraded
for measurably better energy, water, human health and natural resources outcomes.

The first Building Performance Initiative summit, in Chicago on Sept. 29, will be
followed by an Oct. 6 summit in San Francisco, an Oct. 8 summit in Los Angeles, an
Oct. 15 summit in New York City, and an Oct. 21 summit in Washington, D.C. These
summits will convene between 75 and 100 people each, and attendees will bring the
experience and expertise of a diversity of sectors, including representatives from
local, state and federal governments, USGBC chapters, LEED project teams, developers,
architects, engineers and many others.

The summits will combine lessons learned from the current state of building
performance – both success stories and signs that improvement is needed – and
USGBC’s proposals for raising the bar on performance. They will provide an
opportunity for participants to view USGBC’s data collection agenda and proposed
analysis methodology and to provide feedback and share their own ideas and insights.
 USGBC will report on these summits at the 2009 Greenbuild International Conference
and Expo in Phoenix, Ariz., Nov. 11-13.

For nearly a decade, LEED has been driving a change throughout the building industry
 that has led to a new consciousness about the way our buildings are designed,
constructed and operated. This new focus on building better buildings has meant
great potential for increased efficiency and sustainability, but USGBC has recognized
that there is a difference between intention and actual performance.

For the vast majority of well-designed and well-built buildings, the performance
advantages are clear. However, when building occupants fail to understand or fully
take advantage of their green buildings, there can be a performance gap that we must
fill if we are to truly transform the built environment. And without an aggressive,
proactive campaign to address performance, the gaps will not be filled.

So the summits are only the first part of the Building Performance Initiative.
They begin an essential national discussion about buildings and will guide the
continued evolution of a program that is committed to real performance in all buildings
through rigorous data collection and analysis, feedback loops and continuous searching
for better ways to design, build, manage and occupy buildings.


Quality data about building performance is key to this initiative and will serve two
vital purposes. First, the LEED-certified buildings that participate – initially,
between 300 and 500 pilot participants dating back to the very first version of LEED
 – will receive detailed information on how they are performing, what’s working, and
 where there is room for improvement. This will allow those buildings’ owners,
facilities managers and occupants to make crucial changes to their own protocols
and may lead to upgrades, repairs and other efforts to fill the gap.


And USGBC’s ultimate goal is that one day, every owner or manager of a LEED-certified
 building will be actively engaged in measuring, analyzing and improving that building’s
 performance. USGBC took the first step toward that goal by announcing that, under LEED
 2009, LEED certification will require project teams to collect and submit ongoing
 performance data, either through their own measurement or by allowing USGBC access
to utility bills and other information.

The second outcome of this data-collection campaign will be its ability to drive
 the ongoing evolution of LEED, USGBC’s strategic planning, future breakthroughs
in green building science and technology, improvements in public policy and
private-sector initiatives, and an overall better understanding of how we can
continue to work toward our goal of green buildings for all within a generation.
Green buildings are living labs, and the Building Performance Initiative aims to
ensure that all buildings contribute to the body of green building research and
knowledge, gaining a better understanding both of how their individual buildings
 are performing and how we can use that information to improve performance
industry-wide.

Earth Advantage Institute Executive Director Discusses Keys to Green Marketing at Building Green Cou

As the number of green builders continues to grow, the number of consumers supporting
the green movement also increases.  The Lifestyles of Health and Sustainability (LOHAS)
demographic is comprised of the most educated and socially-conscious consumers who
 strongly support green goods and services.

The LOHAS population currently accounts for about 17 percent of all consumers,
 and the increasing size of the LOHAS market directly relates to the growth of the
green industry. HBA partner Earth Advantage Institute (EAI), a nationally known green
building resource and educational organization, continually updates its builder programs
with data about the LOHAS demographic. This information is essential to understanding
the demands of the marketplace and determining new ways to reach this important group
of consumers.

The HBA of Metropolitan Portland is pleased to announce that EAI’s Executive Director,
 Sean Penrith, will discuss LOHAS and a variety of other topics at the Building Green
Council Breakfast on September 8, 2009.

In his presentation, Mr. Penrith will cover the importance of understanding the LOHAS
consumer segment when designing, building, and marketing green homes. He will discuss
 the different characteristics of this group, how they select their purchases, and what
 they are willing to spend to support their values. He will also highlight the best
ways to engage with the LOHAS segment and the key to explaining green home features
 in a way that is meaningful to them.
