About the Speaker
TERRY E. TOWNSEND, PE
Townsend Engineering
Chattanooga, TN
Terry E. Townsend, P.E., Fellow ASHRAE, is president,
Townsend Engineering
Inc., Chattanooga, Tennessee, and Panama City, Florida.
In 2006-07, he
served as president of ASHRAE, where he focused the Society’s
efforts on The
ASHRAE Promise: A Sustainable Future, highlighting ASHRAE’s
work in
sustainability in the building environment. His achievements
as president
include launching ASHRAE’s first ever certification
program, accelerating and
expanding the Advanced Energy Design Guide series, setting
more stringent
savings for ASHRAE’s energy standard, and proving
resources on how ASHRAE
can minimize the impact of its meetings on the environment.
PROFESSOR S.K. CHOU,
DEPARTMENT OF MECHANICAL ENGINEERING
NATIONAL UNIVERSITY OF SINGAPORE
CHOU Siaw Kiang (S.K. Chou) is Professor and Head of the
Energy and Bio-
Thermal Systems Group in the Department of Mechanical
Engineering at
NUS. From 1998 to 2003, he was Head of the Department
of Mechanical
Engineering. From 1992 to 2000, Chou served as Director
of the Industry and
Technology Relations Office (INTRO), NUS, and concurrently
from 1995 to
2000, the Managing Director of NUS Technology Holdings
Pte Ltd (NUSH), a
wholly-owned NUS company having equities in new technology
start-ups
from university research and inventions. More recently,
he helped found the
Energy Studies Institute in NUS and served as its interim
Executive Director
from September 2007 till January 2009.
Professor Chou’s research interests are in energy
performance of buildings,
clean energy systems, micro combustion and micro power
generation, and
cryosurgical thermal processes. He is credited with having
developed the
formulation of the Envelope Thermal Transfer Value (ETTV)
and the Residential
Envelope Transmittance Value (RETV) criteria in the present
building energy
standards used in the Singapore Green Mark Scheme. His
research team has
been cited for its pioneering work on portable power generation
based on
the micro combustor-thermophotovoltaic system. Chou is
ASHRAE Fellow and
Fellow and Vice-President of the Institution of Engineers,
Singapore. He is
Associate Editor of Applied Energy, and serves on the
Editorial Board of the
International Journal of Energy Research.
Professor Chou obtained his Bachelor of Engineering (B.Eng.)
from the
University of Singapore, and the Diplome d’Etudes
Approfondies (D.E.A.) and
Docteur-Ingenieur (Dr-Ing.) from Ecole Nationale Superieure
d’Arts et Metiers
(ENSAM), Paris, on a French Government Scholarship. He
joined the
Department of Mechanical Engineering in 1980.
TOPIC 1: Design Guidance
for New and Existing Buildings in Hot & Humid Climates
ASHRAE has produced two Design Guides for buildings in
hot and humid climates. These
design guides integrate directions for achieving not only
energy conservation and proper
indoor air quality but also proper occupant comfort in
buildings. There is also extensive
information on how to maintain proper moisture control
within buildings without sacrificing
energy conservation goals or acceptable IEQ conditions.
To demonstrate the information
contained in these two design guides as well as ASHRAE's
Advanced Energy Design Guides,
advanced energy conservation guidance will be provided
for office buildings, retail
spaces, warehouses and school facilities. There will also
be a discussion on the guidance
that will be provided in ASHRAE's new Advanced Energy
Efficiency Guide for Existing
Buildings.
TOPIC 2: Enhancement of
the Envelope Thermal Transfer Value Criterion for Improved
Energy Performance of Buildings
Commercial buildings are energy intensive and have a significant
“carbon footprint”. In the
residential building sector, increasing affluence and
desire for comfort have given rise to
the widespread use of air conditioning. This trend has
begun to influence the design of
residential dwellings, which are no longer able to benefit
from the elements of passive
designs but will need air conditioning to maintain indoor
thermal comfort. As a result, the
share of energy consumption by residential buildings will
grow and ways will need to be
found to reduce energy wastage and improve the design
of residential dwellings for
energy efficiency. In this presentation, we share the
most recent Singapore’s experience in
the design and use of the ETTV criterion to achieve improved
energy performance of nonresidential
and residential buildings.
