PAR Platform for Architecture + Research is an offi ce interested in architectural possibilities.
Setup as a platform for exchange within a global context, a team of 10 architects and designerstranslates an ongoing effort of spatial research into building form.
A global, integrated, multidisciplinary fi rm of professionals working together to tackle complex building, design, and systems issues.
10,000 engineers, designers, planners, management consultants and exonomists working in buildings, infrastructure, and consulting
90 networked offi ces in 38 countries

Helsinki Conclusions
Heating dominated climate
Need to increase daylight in winter, but mindful of glare
Solar gain is helpful for all but a few months
Peak summer sun control
Natural Ventilation opportunity in May-September
Facade must prevent heat loss, amplify and modulate dualight, prevent glare, and enable natural ventilation
Rome Conclusions
Cooling dominated climate
Ample daylight year round, glare a concern
Minimize solar gain in warm months (solar control, more solar control...)
Opportunities for natural ventilation in shoul-der season, but daily peaks exceed comfort in summer

Environmental AnalysisSubtractions within the roofl ine increased solar access for upper fl oor areas
while the volumetry along the west orients surfaces to capture daylight.
Solar AccessThe library’s outer contours were designed to scoop light from Helsinki’s
low sun angles during the winter along a 35° rotation against the N-S-axis.

VentilationTo best ventilate the structure, the facade will be closed in the winter
and opened in the summer to bring fresh air into the space.
Performance ParametersTaking a holistic approach, we propose a framework of performative design
criteria based on program and environmental parameters.

Concave Solar CollectorsConcave panel profi les could magnify light and heat, focusing
it into the building and reducing energy demand.

Swirl diffusers for raisedfloor venitlation cooling.
COOLING MODE
Perimeter throughs within the raised floor will conceal linear hydronic radiators to provide perimeter heating
Heat is radiated through a raised floor displacement ventilation system
The facade will be closedin the winter, and
the double skin will provide a thermal buffer to help
retain heat within the building
Snow melted by heated gutter system
Closed vents retainheat in winter
