Sammanfattning
Taiwan's goal is to achieve 'Net Zero Carbon Emissions' in all new buildings by
2050, with over 85% of existing buildings meeting this standard. However,
energy efficiency loses significance if the indoor environment fails to meet human
comfort and health standards. This discrepancy might prompt occupants to
resort to alternative heating or cooling methods, potentially increasing energy
consumption beyond conventional buildings.
Sustainable building strategies in Taiwan, especially in its subtropical climate,
heavily lean towards natural ventilation. Emphasizing thermal comfort and
energy efficiency, these strategies prioritize heat dissipation, dehumidification,
and cooling. They often rely on non-mechanical systems like sun shading and
natural air convection through openings. In contrast, Passive house principles
focus on constructing airtight, thermally insulated buildings without thermal
bridges.
Nevertheless, challenges posed by urban environments, including uncontrolled
temperature, humidity, pressure differences, air pollution, insects, and the urban
heat island effect, question the suitability of natural ventilation in Taiwan's
context.
Since 2010, Passive House, offering controllable indoor comfort, has gradually
found its way into subtropical regions like Taiwan. It aims to provide comfortable
indoor conditions with minimal heating and cooling loads by integrating
structural design and building systems.
This master's thesis endeavors to design a library using Passive house strategies
and compare its performance with buildings relying on natural ventilation. The
research begins by studying the Beitou Library, renowned for its low-energy
consumption via natural ventilation and receiving the highest evaluation index
for sustainable building design in Taiwan.
The thesis will propose a design for a Passive House library and compare its
daylighting and energy performance with the existing Beitou Library. To ensure
an unbiased comparison, the thesis site mirrors that of the Beitou Library, and
the spatial requirements of the original library are considered. By delving into the
redesign of a library, this thesis aims to evaluate the feasibility and applicability
of Passive House principles in Taiwan's architectural landscape.
