The ASHRAE Building Energy Labeling Program
Whether voluntary or mandatory, the rating of the energy
use and indoor environmental quality of buildings is a
growing trend worldwide. In 2009, ASHRAE introduced its
own "Building Energy Quotient" (bEQ) labeling
program for new and
existing buildings and is now in the process of piloting
it in a number of locations around the U.S. It is an ambitious
program comprising not only the development of an energy
use performance scale, but also tools and procedures for
performing ratings and certification of the qualified
energy modelers and building assessors needed to implement
it. This presentation will provide an overview of the
bEQ program, describe its relationship to other building
certification programs in the US and elsewhere, identify
the potential benefits of certification, and summarize
the current state of implementation of the program and
plans for the future.
About the Speaker
William Bahnfleth is Professor and Director of the Indoor
Environment Center in the Department of Architectural
Engineering at the Pennsylvania State University (Penn
State) in University Park, PA, where he has been employed
since 1994. Previously, he was a Senior Consultant for
ZBA, Inc. in Cincinnati, OH and a Principal Investigator
at the U.S. Army Construction Engineering Research Laboratory
in Champaign, IL. He holds BS, MS, and PhD degrees in
Mechanical Engineering from the University of Illinois,
where he also earned an undergraduate degree in music
(pipe organ performance), and is a registered professional
engineer.
At Penn State, Dr. Bahnfleth teaches undergraduate courses
in HVAC fundamentals and controls and graduate courses
in chilled water systems, hot water and steam systems,
and indoor air quality. His research interests cover a
wide variety of indoor environmental control topics, including
chilled water pumping systems, stratified thermal energy
storage, protection of building occupants from indoor
bioaerosol releases, ultraviolet germicidal irradiation
systems, and others. He is the author or co-author of
more than 100 technical papers and 11 books and book chapters.
He consults regularly on the design of chilled water thermal
energy storage systems and has been involved in more than
20 projects world-wide.
Dr. Bahnfleth is member of the American Society of Mechanical
Engineers (ASME), Sigma Xi, American Society for Engineering
Education (ASEE), Society of Building Science Educators
(SBSE), and a Fellow of the American Society of Heating,
Refrigerating, and Air-Conditioning Engineers (ASHRAE).
He has served ASHRAE in a variety of capacities, including
Student Branch Advisor, Chapter Governor, Technical Committee
and Standing Committee Chair, and as a Director-at-Large
and is currently Society Vice President. He is the recipient
of a 1st place ASHRAE Technology Award, Transactions Paper
Award, and Distinguished Service and Exceptional Service
Awards.

The European Energy Performance of Buildings
Directive (EPBD)
From the beginning of 2006 an EU-directive required all
new European buildings (residential, commercial, industrial
etc.) must have an energy declaration based on the calculated
energy performance of the building, including heating,
ventilating, cooling and lighting systems. This energy
declaration must refer to the primary energy or CO2 emissions.
The directive also states that the energy performance
calculation must take into account the indoor climate,
but gives no guidelines. The European Organisation for
Standardization (CEN) prepared a series of standards to
cover the requirements for the indoor environment, energy
performance calculations for buildings and systems, ways
of
expressing energy performance, inspection of heating-cooling-ventilation
systems and conversion to primary energy. In 2010 this
directive has been revised and now the requirement is
that by 2020 all new buildings must be near zero energy
buildings. This presentation will show the European activities
and directives in relation to energy certification of
buildings, required energy performance, CO2 reduction
and use of renewable energy sources. It will also give
the status of the on-going implementation of the directive
and discusses the issues related to the implementation

About the Speaker
Dr. Bjarne Wilkens Olesen obtained an MS in Civil Engineering
from the
Technical University of Denmark in 1972, and a Ph.D. at
the Laboratory of
Heating and Air Conditioning, Technical University of
Denmark in 1975. In
1982, he received the Ralph G. Nevins Physiology and Human
Environment
Award, and in 1997, the Distinguished Service Award from
ASHRAE and the
ANSI Meritorious Service Award from American National
Standard Institute.
In 2001, he became an ASHRAE Fellow. In 2000, he was appointed
as
member of the international faculty and adjunct professor
at the Technical
University of Denmark. Since 2004, he is a Professor and
Director of the
International Centre for Indoor Environment and Energy
at the Technical
University of Denmark.
Dr. Olesen was employed as a research scientist at the
Laboratory of Heating
and Air Conditioning, Technical University of Denmark,
from 1972-90. He
performed research on the influence of the thermal environment
on human
beings (floor temperatures, draught, vertical air temperature
differences,
radiant temperature asymmetry, spot cooling, thermal insulation
of clothing,
measurements of the thermal environment). In 1978-1992,
he worked part
time as product manager at Brüel & Kjaer in planning,
development and
marketing of instruments for measuring and evaluation
of the thermal
environment, indoor air quality and the performance of
the ventilation
system (tracer gas measurements). In 1992-1993, he was
Senior Research
Scientist, Indoor Environment Program, College of Architecture
and Urban
Studies, Virginia Polytechnic Institute and State University,
Blacksburg, VA.
He performed research on indoor air quality and ventilation
in buildings,
laboratory testing of displacement ventilation system,
teaching in calculation
of heating and cooling loads, design criteria for the
indoor environment and
HVAC systems in buildings. During 1993-2003, Dr. Olesen
has been Head of
Research & Development at Wirsbo - "VELTA"
GmbH and Company KG,
Norderstedt, Germany, where he worked with methods and
systems for
heating and cooling of buildings with special emphasis
on water based
radiant systems. Dr. Olesen is chairing or serves as a
member of several ISO,
CEN, ASHRAE and DIN standards committees related to thermal
environment, indoor-air quality, ventilation and heating
and cooling systems
in buildings. He has published approximately 240 papers.
