 Field work: October 2011 December 2012
 Participant observation
 60 in-depth interviews
 Microclimate data collection

1. Microclimate preferences
2. Regional outdoor culture
3. Adaption to local climate

METHODS

Three main themes:
Microclimate preferences

I would say its probably the wind that is
more annoying, because if you can step
[out] the wind and be in the sun, it
usually... You feel ok; you can trap the
wind out. (044)
I dont think it ever gets too cold in
Christchurch that you cant go out and
do something. New Zealanders are a sort
of tough people, we dont let things get
on our road, so we would just put a few
more layers on and go out and do it. So I
dont think here the climate would
affect me doing something. (026)

THEMATIC ANALYSIS

That is always the problem. You find the
day quite hot, but then you drive all the
way out there, but it is so windy. (059)
Ive got a boat, like fishing and hunting,
tramping, I like mountain biking. I used to,
but I dont have time for camping these
days (). Ive got a property in Harewood
which is a five acre block () Well, I used
to get out a lot, used to go hunting every
weekend or every second weekend Id be
out in the mountains. (022)
I think it is understandable when you look
at the lights in China (). But people in
this country buy their quarter acre
section for a reason, because they have
grown up with that, and that is in their
blood () In this terrible financial times,
there is so many people doing their own
little vegetable garden, if that is gone,
then what else? (044)

THEMATIC ANALYSIS

Regional outdoor culture
I think there is an argument that I have
particularly with my son that lives in
Australia, in Brisbane, where it is very
hot. And () my opinion is that you can
dress for the cold, you can put more
clothes on. It is much harder to be
outdoors in the heat, over 30属C the heat
is just beyond me, I cant cope. (040)

If there wasnt many people [in the
city], maybe I wouldnt have come.
The perception of having people
there makes me feel not as bad
[about] the weather. But depends on
what you are doing, so you might
want to go somewhere to have more
solitude. (043)

  5. Christchurchis the largest city in theSouth IslandofNew Zealand, and New Zealands third-largesturban area. The city has a temperate, relatively dry climateTypical summer daytime maximum air temperatures range from 18属C to 26属C, but may rise to more than 30属C. A maximum temperature of 42属C has been recorded in Christchurch. During the winter typical daytime maximum air temperatures range from 7属C to 14属C (NIWA, 2013). Northeasterly winds are common around the coast for much of the year. Southwesterlies are more frequent during winter, and tend to bring rain and reduce air temperatures. Northwesterlies are possible at any time of the year, and during summer the highest temperatures occur when this hot dry f旦hn winds blow over the Southern Alps and Canterbury plains. Northwesterlies can raise the temperature by 10-15属C within an hour or so.The sun tends to be very strong, because there is less ozone to block the UV rays, the Earths orbit takes it closer to the sun during the southern summer than during the northern summer, and there is less pollution in the southern hemisphere to block the UV rays. Christchurch is located on 43.3 degrees South latitude, and is cooler during the summer months than cities with the same latitude in the northern hemisphere because of the moderating effects of the surrounding Pacific Ocean (ENZ, 2013).

  8. two key variables were the social nature of the space, and its urban condition pre- and post- quake. The investigation started with two Established Urban Settings that were minimally affected, and extended to two new Emerging Urban Settings which had been re-designed as temporary post-earthquake solutions
  9. explore the urban comfort perceptions of Christchurch residents in urban settings. distinctive feature is its focus on the way people are adapting to both surviving pre-quake urban settings and new post-quake environments. An interpretive research strategy has been adopted using different approaches to qualitative data collection, based upon naturally occurring data, principally participant observation and semi-structured in-depth interviews
  10. Field work results suggest that certain socio-cultural characteristics do indeed affect adaption to the local climate. New Zealanders claim to like fresh air, and sometimes it means temperatures around 8-9属C. Especially in Christchurch the wind can be seen as a good thing for general purposes, as it keeps pollution awayDuring the coldest days, the sun can make a considerable difference if the place is protected from prevailing winds. In combination with the usual air low humidity, when the sun in out, temperatures tend to rise quickly.On a cold frosty winter day, when a high of 14属C was registered for Christchurch in the official MetService system (MetService, 2012), our weather station placed in Windmill Centre, which faces north and is protected from the east, recorded temperatures of up to 24属C. This highlights an important aspect of urban designHowever, even on winter days, a cold day with no wind but sun is considered a nice day. In fact, the majority of respondents expressed more discomfort with hot than cold weather, frequently saying that local weather does not prevent the use of outdoors spaces. The physiological thermal comfort model usually assumes comfort between 19-26属C. Overall, respondents in Christchurch seem to feel comfortable in a wider range of conditions, as indicated that single digits makes them feel cold. Conversely, an interesting aspect of the warmer days is that while over 25属C has been widely described as hot, most respondents think Christchurch never gets uncomfortably hot because of its frequent wind.
  11. accessibility to outdoors, preference for living out of the city, peaceful context and connection to nature, opportunity for sports practice and backyard space. quality of life: The need for providing a vibrant central city and, at the same time, peaceful surroundings for living was extensively expressed as the ideal urban environment. For locals this outdoor culture was expressed as sports and outdoor recreation or gardening. New Zealands South Island offers a diversity of landscapes, from mountains to plains and beaches, and a variety of outdoor recreational activities such as skiing and wakeboarding.The background and the way the respondents grew up also seem to influence outdoor preference. In the 60 interviews at least 18 sports and recreational activities were mentioned: soccer, cricket, four wheel drive, kite surfing, diving, fishing, hunting, motorcycle, cycle, netball, golf, horse riding, kayaking, sailing, ski, tennis, snowboarding and rock climbing, all of them practiced outdoors. Furthermore there are the frequent outdoor runners and walkers, stressing the extent to which outdoor activities are present in New Zealanders lives. in some cases gardening was added as a seasonal substitute for sportsAlthough higher density is frequently acknowledged as a sustainable solution, as it saves distances and enhances social and economic sustainability, the value of space is a strong characteristic of Christchurch. In this sense high density is not seen as desirable. the backyard is sometimes regarded by locals as important in times of crisis.the title of The Garden City and gardening activity makes locals better understand the seasons, and as a consequence, behave differently toward the climate and what to expect. Respondents who claimed they did not have time for gardening, said they often had small areas for herbs and vegetables, and respondents that chose denser lifestyles tend to accept it if one can keep some greenery around the place.
  12. Christchurch residents have a very particular attitude toward climate, but it is not so much about how they feel it, but how they perceive and adapt to it. Climate perception when described by sports people highlighted how the activities influence their general perspective of the local climate. When respondents were asked if they find Christchurch windy, the kite surfer said it is not at all; otherwise he would have the chance of practicing his favourite sport more often. On the other hand, cyclists find it very windy and described the sensation as biking into a brick wall (against easterlies).The amount of greenery also appears to influence the adaption to climate. some greenery around or a tree to sit under (027). Within the city some places are popular because of their orientation, in most cases facing north or west and protected from easterlies. respondents tend to feel more comfortable in cooler temperatures than those ones tending to hot. This makes easier for them to adapt to colder temperatures.Besides outdoor activities, the sense of personal space and the way other people use public spaces also affects choices and time spent in places. There has to be balance between those two variables, in a way that the environment is interesting and vibrant and there is enough personal space.Sports were frequently referred as a way of socializing, and the preferences for places and activities are affected by having (or not having) company. In some cases company is said to be substituted by enjoying the city environment. In other cases the opportunity of enjoying company also influences the attitude toward climate, because people tend to adapt easier or at least find a way of adapting to be able to stay for longer. Urban density has also been illustrated as a climate attenuator.
  13. In Christchurch the most important variables for urban users are wind and sun. For instance, a place with direct sun light and protected from the prevailing winds can be used throughout the whole year. For instance, a place with direct sun light and protected from the prevailing winds can be used throughout the whole year.The theoretical implication is that to understand urban comfort, one must consideradaptive strategies. from the perspective of local outdoors culture and its socio-cultural meanings, adaption is based on more variables than a given range of thermal comfort. The results also demonstrate the influence of social life on climate perception and adaption. Outdoor culture, as understood in this study, also influences the perceived nature and level of urbanity. The design implication is the identification of urban landscape design solutions that best respond to the characteristics of local climate. The findings also suggest that in Christchurch, the strong connections between urban and rural settings present in culture, lifestyle and landscape seem to increase the desire for contact with nature within the city. This generates a particular aesthetic and recreation preference for urban spaces, which in turn influences the way people adapt to urban microclimatic conditions. City planners and managers typically perceive the liveability and vibrancy of the city based on the numbers of people and business success in a central district. However, what the meanings of urban comfort are, and how it is experienced by the urban residents are questions rarely addressed. This research highlights that the citys rebuilding requires special attention to aspects of urban comfort that extend the use of open spaces throughout the year. Increased numbers of people and longer periods spent in public urban spaces and streetscapes will enhance both civic life and the socio-economic revitalisation and sustainability of the city.
