Abstract: Objective: This study examines the integration of
wind turbines into buildings by focusing on how roof form
shapes wind flow around the building envelope. It evaluates
the aerodynamic effects of different roof geometries on rooftop
wind conditions and their impact on the energy performance
of building-integrated wind turbines. The main aim is to develop
roof-design strategies that support increased renewable
energy generation in buildings.
Method: The research is grounded in a structured evaluation
of wind-flow analyses, wind-tunnel-based findings, and
peer-reviewed literature focusing on building roof forms in the
context of wind-energy harvesting. Within this scope, pitched,
flat, curved, and multi-sloped roof geometries are examined,
and their effects on wind directionality, velocity distribution,
and flow intensity/turbulence characteristics are comparatively
assessed. The resulting evidence is synthesized to derive
form-based design criteria intended to enhance wind performance
in roofs designed for wind-turbine integration.
Findings: The findings indicate that roof form exerts a direct
and decisive influence on wind flow around buildings, particularly
at roof level where turbines are typically installed. Roof
geometries featuring appropriate slope angles or aerodynamically
shaped profiles can accelerate flow, improve coherence,
and thereby increase the operational efficiency of integrated
wind turbines. In contrast, flat roofs may, under certain conditions,
impose performance limitations due to reduced flow
guidance and locally unfavorable turbulence patterns. Carefully
designed pitched or curved roofs, however, can more
effectively steer airflow along the roof surface, improving
wind-resource quality at candidate turbine locations. Overall,
the results demonstrate that roof form should be treated as
a strategic design variable in early-stage decision-making to
maximize the utilization of rooftop wind energy.
Conclusion: The effectiveness of integrating wind turbines
into building roofs largely depends on roof geometry and related
architectural decisions. Under suitable conditions, flat
roof forms can improve rooftop flow and energy performance;
however, this effect varies according to prevailing wind direction,
building height, and the surrounding urban context. In
addition, different roof forms may offer advantages for turbine
placement at roof-center zones or windward edge/corner
regions due to their relatively stable wind conditions and, in
some cases, higher power density potential. This study highlights
the necessity of an integrated architectural–aerodynamic
framework.
