WHY MICROCLIMATES MATTER
Landscape architects can gain powerful
design insights through microclimatic
site analysis. The science can inform
designers working to create the most
comfortable designs, often in intensely
challenging environments. In the
case of the New York Times Tower, we
worked with HMWhite Architecture
and Planning and Cornelia Oberlander,
helping them design both a ground level
courtyard and rooftop decks that would
maximize human thermal comfort. On
the 53rd storey roof deck, we added
ceramic windscreens to reduce wind and
improve comfort.

67TH STOREY
TERRACE

wind, for example, and increasing access
to shortwave radiation (allowing the sun
to shine in).
THE SOLAR CARVE
Working again with HMWhite and
StudioGang, we analyzed two rooftop
spaces (the 2nd and 11th storeys) on
the new Solar Carve project along the
High Line. Since it is important that
no shadows be cast on the High Line
Sun Deck, the shape of the building

was 'carved' according to angles of the
sun. The process was similar to that
used at Hudson Yards: the scientists
and designers worked together to
understand the base conditions of the
site and then to modify the design.
What does the future look like? We're
collaborating with Dr. Tim Logan, an
atmospheric scientist, to develop a new
kind of instrument pack. Check out our
sidebar of new instruments, page 45.

MORE COMFORTABLE ROOF DECKS
More recently we've worked with
HMWhite in New York on the 15 Hudson
Yards project, where we looked at the
impacts of adding full or partial glass
panels to improve both human comfort
and plant health on the 67th storey
roofdeck terrace. Using Autodesk
Flow, we simulated the wind impacts
of the various design options and then
simulated other microclimate variables as
inputs into the COMFA Model to assess
human thermal comfort in specific places
on the roofdeck. The results, which
were simple plots of comfort at various
locations on the rooftop, provided
designers with the information they
needed to modify their designs to make
deck spaces more comfortable.
COMFA identifies problematic energy
flows which can be addressed through
design. For example, when COMFA
pinpointed locations that received too
much solar radiation during mid-summer,
we tested various shading devices to see
which had the best effect. In some areas
trees were sufficient to achieve thermal
comfort, while in other areas we needed
umbrellas or other solid structures. The
same analysis shows designers how to
increase winter comfort, by blocking
