Lunenburg County
Lifestyle Centre
South shore Nova Scotian building combines sustainable
design and local culture
By JarLe LovLiN
Both the land and the sea provided design inspiration for
this new lifestyle centre on the south shore of Nova Scotia.
Lunenburg County is both coastal and deeply forested with
centuries-long traditions of timber construction
and wooden boat building.

Both the land and the sea provided design inspira-
tion for this new lifestyle centre on the south shore of
Nova Scotia. Lunenburg County is both coastal and
deeply forested with centuries-long traditions of timber
construction and wooden boat building.
Rolling hills overlook the many bays along the
Atlantic Ocean where the Lunenburg County Lifestyle
Centre sits within an undulating forest setting. This
context informed the design approach for the project.
The $35-million facility hosts community, recreation
and cultural events while promoting individual health,
literacy and fitness. The engaging connections created
by the diverse program, visual transparency and a clear
plan create a strong sense of place and a destination
embraced by local residents.
The 10,200m2 recreation program is divided into four
main components: an NHL regulation-sized ice surface;
an aquatics facility that includes a six-lane, 25-metre
lap pool, a leisure pool, and a therapy spa pool; a
740m2 regional library, and a complement of fitness,
multi-purpose and administrative spaces.
The arena is acoustically designed to operate as
a hockey rink, concert venue and conference facility.
Raised seating in the arena provides improved specta-
tor viewing and unimpeded circulation around the rink
for conference and concert use.

The joint venture architectural team wanted to achieve a strong architectural
expression that would be regionally and culturally appropriate, while addressing an
ambitious environmental agenda on a demanding site.
One of the challenges was to accommodate a five-metre drop in landscape running
diagonally across the site from west to east. Taking advantage of the natural slope,
the arena was nestled into the hillside, so that the upper concourse seating would be
at the facility’s entry level. The more contemplative program elements were located
at that southern end of the building, providing light, views and direct access to a
landscape of preserved trees and the stream that defines the southern boundary of
the site.
A central Galleria runs parallel to the arena and aquatic centre, with the library at
the southern end. The naturally daylit Galleria is the main street of the project, pro-
viding the strongest reference to the timber industry and maritime heritage of the
region. The upper levels are lined with linear maple hardwood slats that provide both
visual warmth and - by way of their open spacing - an acoustic dampening function.
The ceiling is a combination of 38 mm-thick tongue-and-groove wood decking and
Douglas fir glulam beams.
Tying the beams together are a series of king post trusses which gradually arc along
the length of the Galleria, emblematic of the draft of the famed Bluenose I schooner, a
cultural totem for the surrounding communities. This wood-lined Galleria is a dramatic,
unifying element, providing physical and visual links to all the activities within the facil-
ity, as well as to the forested vistas beyond.

The community expressed a strong commitment to sustainability, and LeeD Gold certifica-
tion is being pursued. A number of initiatives were implemented to reduce the environmental
impact and energy demand of the building.
Given the scale of the building enclosure, a high-performance building envelope was
employed with R25 walls and an R30 roof assembly. The building incorporates several ener-
gy-saving elements into the design of its mechanical systems including heat recovery for the
arena refrigeration plant that captures waste heat for pool water heating, dual core energy
recovery ventilators made in Manitoba, roof-mounted solar panels for heating domestic and
pool water, and variable speed drives on fans and pumps. The dehumidification system con-
trols the relative humidity in the pool area, but also recovers the heat contained in the water
vapour in the air and recycles it back to the pool water to deliver significant energy savings.
The system also uses a glycol loop to recover energy from the exhaust air to heat incoming
fresh air for ventilation purposes.
A geothermal field provides storage and a retrieval source for the waste heat, while recy-
cled grey water collected from the roof is stored in a large cistern and used for plumbing and
irrigation purposes. electric car charging stations are located in the adjacent parking area.
The Galleria itself provides a source of natural ventilation, taking advantage of its height
for stack effect. Motorized windows at both the north and south end provide low-level entry
while upper level clerestory windows allow the hot air to exit, activated with temperature
sensors and monitored by the building management system.
The result is an integrated and sustainable facility, highlighting its spectacular natural loca-
tion and paying tribute to its industrial and maritime roots.

Athena’s eBDs are compliant with the european standard eN 15978,
a whole-building life cycle assessment [LCA] standard that is intended
to support decision-making and documentation around the assessment
of environmental performance of buildings. Since one of the stated pur-
poses of the standard is to guide “environmental declarations,” we’ve
adopted the name “environmental building declaration” for this kind
of report. while many people are using eN 15978 in their practice and
reporting of whole-building LCA, Athena may be the first to formalize the
documentation and apply the term “eBD.”
an introduction to environmental building declarations By Jennifer O’Connor and Matt Bowick,
Athena Sustainable Materials Institute
the Athena Sustainable materials Institute recently
began publishing a new kind of document, something
we call Environmental Building Declarations [EBDs]. An
EBD is a summary report of comprehensive environmen-
tal footprint data for a building and declares the life cycle
impacts of a building according to a standardized format.
It is a statement of performance and is typically publicly
disclosed, like a nutrition label on a food package.
the intent of the document is to present results
as transparently and concisely as possible.
the en 15978 standardeN 15978 is the most advanced consensus standard for whole-
building LCA. It includes provisions on how to calculate results for
a uniform set of environmental indicators, and how to report the
results transparently. The standard has filled a critical gap in build-
ing LCA practice and taken the guesswork out of what constitutes
a good assessment. eN 15978 is now the most widely-used stan-
dard for building LCA studies and is referenced by various green
building rating systems worldwide. Athena’s eBDs aim to advance
the emerging consensus on whole-building LCA practice.
Quantification and validation of green building Performance
Our mandate at the Athena Institute is to help bring quantifi-
cation and validation to sustainability decisions. How confident
is the design community that self-declared “green” buildings
deliver measurable environmental benefits over standard build-
ings? we believe it is time for performance assessment and
standardized transparent reporting on what the community
calls sustainable design.
