Throughout the design process of the Constitution hill retro fit, there were many
influencing factors to be taken into consideration. One of which being the new Luas
line that is to be put in place in late 2017. We took into consideration very carefully
that there will be huge increase to the amount of people coming through the site on
a daily basis, from this we have designed a retail space on ground level which can
be accessed by the main road. We also changed the layout of the apartments by
allowing the balconies to face the communal garden allowing privacy for the occu-
pants and the access decks to face the main road instead of the original layout.
The existing building is not com-
plaint with space standards in
any room within the apartments.
From this we came up with a
suitable design to allow each
apartment to be not only com-
pliant with Dublin city council
space standards but also com-
pliant with the current Technical
guidance documents.

PASSIVE HOUSE ENERGY RETROFITS
The retrofit strategy proposes Design and Certification
of retrofitting to Passivhaus EnerPhit standards. This will
involve optimised super low energy fabric insualtion levels,
near elimination of thermal bridges, air tightness to minimise
heat loss, maximim use of solar gains, a high level of indoor
air quality and an efficent mechanical ventilation system
with heat recovery.
EXISTING BUILDINGS - ENERGY ANALYSIS
The energy performance was examined using DEAP soft-
ware, U Value calculation software and linear thermal bridge
modelling. The DEAP analysis clearly indicated a major
improvement of energy standards as every result was an
G BER rating. The biggest loss was through the buildings
fabric. The openings and walls were the main cause of heat
loss.
LOW ENERGY RETROFIT PROJECT
The project proposes a sustainable design strategy for the
energy retrofitting, refurshment and renewal of an existing
Dublin City Council multi storey “flat top” residential apart-
ment blocks located in the heart of Dublin City’s Centre.
A number of issues were addressed including sustainable
urban living and energy conservation.
