Course: Environment and Technology in De-
sign - University of Sheffield
Work: Group
Students: Maria Englezou, Anaclara Penha
Year/Semester: 2016 / Semester 2
Name of Supervisor: Teresa Hoskins
Softwares used: Autocad, Sketch up, ICE da-
tabase, Velux Daylight Visualizer, Heliodon,
Artificial Sky
Contribution to the project: concept develop-
ment, research for low-impact timber materi-
als, embodied carbon and energy, prepare
2d and 3d models, daylight analysis, model
making, presentation preparation.
Description: This course was based on the pro-
ject area, Park Hill, from the Studio module.
Further research was done in order to design
a detailed shading device. Analysis was car-
ried out for daylight with illuminance analysis
and daylight factor levels. The design of the
shading device is comprised of 6 cassettes
which can be manually moved up or down
and the louvers can be tilt or closed. The con-
cept is that each user can change the shad-
ing however they want. Moreover, in order to
reduce the environmental impact of the tim-
ber used, we calculated the embodied car-
bon and energy of four timbers (western red
cedar, sweet chestnut, European oak and Eu-
ropean larch). The weight of the cassette was
also calculated.
As a result of the above analysis, we conclud-
ed that western red cedar would be the best
choice because it had the lowest weight for
the cassette while at the same time had the
lowest embodied carbon and energy.
