7PHN Sustainable Cities and Buildings
Brings practitioners and researchers together
Welcome to the 7th Passivhus Norden conference, 7PHN
Living is multifaceted, even living sustainably. So is maintaining a sustainable society and creating new parts of it –
cities and buildings. To fully succeed in our work, we must look to greater perspectives and frameworks as well as the
detail, quality and actual performance. That is what the multidisciplinary organizing team as well as the program of
7PHN reflects. The program combines the scientific format with reviewed papers and posters with invited speakers,
which all bring interesting experiences.
We look forward to meeting you and wish you a very good conference.
The conference is organized in cooperation between:

Schools of Architecture, Design and Conservation

The municipalities mention unfortunate internal incentive structures, procurement rules, framework agreements and lack of internal resources to
motivate individual stakeholders. Secondly there are distinct limits to the
direct influence municipalities can have: They own relatively few buildings
and only have little influence on choice for transportation let alone foods,
which are two significant sectors in the overall environmental impact. How
should this be handled?

buildings, which decrease in value. In turn, there are expenses when building
replacements in the metropoles.

HOW DO WE ASSESS PROGRESS IN THE FUTURE?
Moderator: Ulrik Jørgensen, Centre for Design, Innovation and Sustainable
Transition, Aalborg Universitet
If genuinely sustainable buildings last 100 years, we need to imagine possible framework conditions under which they should function.
GDP-growth has been made a central target in any country‘s planning.
However GDP does not directly measure how well we are doing. Furthermore, a high indexed GDP is partially contradictive to saving on resources.
Therefore other leading indicators may very well be implemented within the
life time of present new-builds and refurbishments. What will this mean to
cities, buildings and the building industry?

7PHN Sustainable Cities and Buildings
Brings practitioners and researchers together
Annette Blegvad, Director, Policy & International Relations, The Danish Architects‘ Association
Keynote speakers
Welcoming address by the president of the UN General Assembly Mogens Lykketoft one of the most prominent politicians, to have started the discussion on quality of growth. This can have significant influence on cities, buildings and
building industry in the future.
Architect and Professor Walter Unterrainer incarnates the span of the conference from specific knowledge
about details to the greater perspective on sustainable society. He comes from Vorarlberg, where he has planned simple, location adapted buildings, but is equaly satisfied working with students venturing to the poorest
neighbourhoods in Mumbai.
Design engineer Nick Grant and many of his peers in the UK have been involved with eco-building, which
did not perform in terms of comfort or energy use and so the hot topic today is the ‘performance gap‘. In
2007 he attended his first Passivhaus Conference and returned inspired but with many questions. Nick
will share his story and lessons learned. He welcomes robust debate and is generally happier talking
with sceptics rather than believers. Nick will show us a range of buildings that he has worked on from
single homes to schools and a Passivhaus archive that owes more inspiration to Denmark than
Germany.
Welcome to the 7th Passivhus Norden conference, 7PHN

We look forward to meeting you and wish you a very good conference.
Civil Engineer and Professor Kristian Hertz is an example of being able to break down the
walls between research and practice. The company Abeo‘s super light SL-decks and pearlchain reinforcement reduce embedded energy dramatically, meets strict fire and sound requirements, and give a larger freedom in design. Abeo was announced the unofficial world
champion of cleantech at the ”Cleantech Open Global Ideas Competition 2010”
