An affordable, green design integrating thermal efficiency from sustainable and
environmentally friendly materials to meet the Passivhaus retrofit design standards.
Open spaces with maximum natural lighting
Research was put into identifying the most modern and energy efficient materials
available to ensure a new way of life for students/occupants that does not cost the

Structural Insulated Panels (SIPs)
• Offer fast-track, lightweight
building solutions
• Cost effective approach and are
quick and easy to install
• Manufactured using high-pressure
foam injection to create strong
composite panels that can be
used as wall, roof and floor
panels to create highly efficient
• U-value of 0.14 W/m2K

Energy Efficiency - Lighting
Why is it important?
The efficient use of energy and the resulting cost savings are, nowadays,
a concern not only of governments and officials as well as the general
population. This concern increases when it becomes aware that it is
not merely a matter of saving or, if you prefer not to spend, but also
to preserve the environment that surrounds us. Thus, environmental
concerns, such as CO2 emissions to the atmosphere and the
consequent rise of the planet and increase of the ozone hole
temperature, take paramount importance in our daily concerns.
The proposal
Replacing existing light bulbs with more efficient bulbs;
Combine energy efficiency and lighting quality;
Maintain comfort and user satisfaction;
Reduction in electricity consumption and costs;

Terrace boards for the Phase B:
Low maintenance
Eco-friendly materials
60% reused wood + 30% high density polyethylene
(reused plastic)+10% colour + UV stabilizer
The lifespan of the boards of 25 to 30 years and are
90% reusable.
Stands for terrace:
stands/feet are 100% reusable
not affected by any atmospheric impacts (UV/t)
The load of each foot is distributed to an area of
320 cm2
