The most remarkable findings of the literature review of comfort place are mainly focused on indoor place and only apply one of the environmental dimensions: thermal, acoustical, visual or oudor. Other limitations of this reseach subject are that they have a negative and objective perspective. Although the concept of comfort refers to the wellbeing of people, most of the instruments and studies analize the discomfort, ie, what prevents this. But, it is not clear that the comfort is just the absence of disease. These results indicated a need to avance in the study of urban comfort with a global approach. This is the challenge of Tecnalia Urban Team.

We consider that acomfortable urban place is “a urban space that is able to generate a nice environmental experience in people and communities who use it to develop individual or social activities, among which are those of social interaction”. This is an integral and systemic concept that integrates several environmental dimensions (acoustic, thermal, light and visual, and odour, in future developments) in holistic way, it also includes the objective perspective together with the subjective one, integrating the person and usingits perspective (Socio-Ecological System Services) and from a possitive point of view. In addition to this,the approach is to overcome the existing reductionism to consider comfort just as the absence of discomfort.

The methodology to define a urban place as a Comfort Urban Place is estructurated around six steps: 1) space analysis, 2) environmental comfort diagnostic, 3) comfort evaluation ofthe place, attending at its use, 4) values to optimal comfort and proposal of actions, 5) colaborative design (together to arquitects); and 6) final design"tailored".

A questionnaire was designed to pick up the perception of people who use the urban places in relation to comfort of these places. This tool is based on conceptual model of Environmental Experience (Herranz-Pascual et al., 2010). People are asked about their perception in relation to especific aspects of the thermal (temperature, wind…), acoustic (natural, traffic, social sources…) and light and visual dimensions. Also, questionnaire include global scales of urban comfort for each environmental dimensions and with urban place globaly in terms of pleasant.

One of the first outputs of the work is the development of an integral indicador of light/visual comfort following the approach defined for the acoustic and thermal indexes.The second result is an integrated indicator to evaluate environmental urban comfort. This global index has been validated with the perception of people who use an urban place

As conclusion, proposal of Comfort Urban Places developed by Tecnaliaallowsus to tacklesome of the majorchallengesof our cities. The design of our urban places based on this approach can increase the attractiveness of cities for inversion and tourism, also improving the wellbeing and quality of citizen life. The urban places with comfort label by Tecnalia will be singular places where citizenship will be able to enjoy, relax, talk, walk… They will be special and different from other places (place identity).
