Franklin Field –
Weiss Pavilion
Philadelphia, PA
The LEED Silver project
was the conversion of
45,000 square feet (SF) of
space below the existing
grandstand of the historic
Franklin Field into a
weight training facility.
Energy efficient
strategies associated with
the heating, ventilating,
and air conditioning
(HVAC) systems that were
employed to earn the LEED
Silver rating included:
CO2 monitoring with
demand-controlled
ventilation, and airside
economizer. Other features
associated with the HVAC
systems that contributed
to the LEED Silver rating
were: enhanced
commissioning, outdoor air
delivery monitoring,
increased ventilation, and
construction IAQ
management plan during
construction. The HVAC
systems for this project
were designed by Larsen
Angel, Principal of Green
Building Energy Engineers,
while he was employed by
another firm. |

Humidity Evaluation
and HVAC Upgrades
Sykesville, MD
The project involved the
replacement of three air
handling units to address
the source of high indoor
air relative humidity
within the approximately
100,000 SF building.
The replacement units were
equipped with
humidification and
dehumidification
capabilities to ensure
that the 100% outdoor air
delivered by these units
was properly conditioned
to maintain an acceptable
indoor air relative
humidity within the
building.

Dual Temperature
Water Cool-Down System
Frederick, MD
The project consisted of a
system which enabled the
dual temperature
heating/cooling water in
the two-pipe system to be
cooled from the operating
heating water temperature
to the operating chilled
water temperature in less
than three hours.
Prior to implementing
these upgrades, the water
in the two-pipe system
would take up to three
days to cool sufficiently
for the chillers to
operate. This resulted in
uncomfortably warm
temperatures within the
building during the spring
and fall seasons of the
year.

Humidity Evaluation
and HVAC Upgrades
Hunt Valley, MD
The project required an
evaluation of the existing
HVAC systems to determine
the causes for high
humidity levels within the
building during the
cooling season.
Upgrades to the central
ventilation systems were
designed to ensure that
the ventilation air is
properly dehumidified
prior to introducing it to
the building.
Simplified and
consolidated control
systems were also designed
to enable the building’s
HVAC systems to be
monitored and controlled
by members of the church’s
board of trustees.

ventilation were
incorporated into the
control systems for the
units for energy efficient
operation.
