Overview
• What is sustainability re: Irish (urban) housing & communities? • Many dimensions, but focus here:
• Residential density
• Built-forms
• Public and active transport
• Rationale for selection: • well-being, social inclusion, equity
• but also have natural environment & climate change dimensions (not really discussed here)
• How is Ireland doing?

1. What is Sustainable housing/community in Irish context?
a) Residential density
• Resisting urban sprawl
• Brown > green-field• NB: blue & green
• Mixed use
• Good public transport (time)• Renewable energy

b) Higher residential density & built-forms
• Why?
• Land & energy efficiency• Supports mixed use &
sustainability of services• Most journeys active /
public transport

Higher density =/= high rise

b) Higher density built-forms ctd
• Life-time adaptable, flexible housing & communities
• Accessibility: all ages & stages

b) Higher density built-forms (ctd)
• Requires high quality housing • Dwelling: light, noise etc• But aspects of neighbourhood quality higher correlation
with quality of life (Winston)• Crime, safety• Pollution (air, water, noise…)• Green/blue space (Scott et al)
• leisure, food, local energy, waste, pond, river…

b) Higher density built-forms (ctd)
• Require affordability & social mix
• Ensure viability of local services, trades & skills• Avoids social wave syndrome (Barton, 2000)
• almost all initial residents @ same family stage • uneven demand for services
• creches, schools…nursing homes

b) Higher density built-forms ctd
• Require social resources
–Community services & centres
• Meetings, parties
• Libraries
• Leisure resources
• Children, teenagers, older people
–Community development, networks & social capital

c) Transport
• Good quality, frequent, accessible public transport reduces• car use• car dependence• social exclusion (move or eat?)• ‘obesenogenic environments’

c) Transport ctd
• Facilitate walking & cycling (e.g. ‘Home zones’)
•Significantly reduce motorized vehicles
•force them to drive slower
•Alter streets
– benches, play areas, green space
•Community quality of life, health benefits

2. How is Ireland doing?a) Urban sprawl & built form
• Sprawl common trend EU but Ireland extreme case (Budovic et al; Williams & Redmond)
• One-off housing, open countryside: rising again, Ireland extreme case (Brady)
• Some ‘returners’ but some escaping urban problems (Scott et al, Winston)
• Affordability
• Poor quality of urban life
• Ireland outlier in EU in favouring ‘houses’ (urban & rural)

How is Ireland doing (ctd)?
2. Transport
• Car dependence & social exclusion• Urban (Wickham)
• Dublin v other cities• GDA but also Dublin• Move or eat (Drew, Winston & Koeppe)
• Rural
• Transport inequities & Dublin suburbs (Ahern et al) • Very long commuting times via public transport• Forced car ownership• Low- & middle-income groups

Towards more sustainable urban communities
1. Increase supply via higher density, high quality urban communities• Multi-family housing (incl. apartments): higher space standards
(Gallent at al; Winston)
• Alternative tenures (e.g. co-ops): older people, separated/divorced
• Densify suburbs: space for environmental, economic & social infrastructure (Bramley et al) • BedZed, London
• NB: Good quality green & blue space (Scott et al)

Towards more sustainable communities
2. Transport
• Improve proximate, fast, & affordable public transport
• Reduce cars (taxation, speed …)
• Cost Benefit Analysis: benefits of transport-oriented developments v dispersed settlements (Williams et al)

Final points: sustainable communities
• Not an end state, evolve over time, responsive to different contexts
• Requires holistic approach• Depts: Housing, planning, transport, energy, climate change
• Environment, economic, social trade-offs • Long-term thinking essential….costs will be brought down or save elsewhere
(e.g. health)
• Long legacy of construction if get it wrong: costs of retrofitting, pushing people out

Final points ctd
• Explore alternative pathways • actors & their connections? goals & values prioritized?
• different understanding & capacities to present pathways for change…
• Implications for marginalised households & communities
• equitable access to services & social resources
• reducing transport poverty & inequities
• Reducing leisure poverty/inequities [infrastructure (blue & green space), commuting time, …]
• Improve well-being (mental & physical), equity, social inclusion.
