Description
For larger area of window with furnace and heat pump systems
When increasing the area of windows, the design with heat pump decreases more energy because it not only decreases heating energy but also reduces hot water consumption

EVALUATION AND DEVELOPMENT OF SOLAR CONTROL SCREENS
Printing:DAYLIGHTING & THERMAL PERFORMANCE
Description
Background Research
Existing Design
This research examined the geometries in 2D and 3D dimension with four parameters including view, DGP, UDI and solar radiation. The perforated screen represented 2D base case and the louvers were 3D tested case. The measurements were simulated in Los Angeles and Seattle by Ladybug and Honeybee, and the louvers were from 0˚ to 75˚ in matte and specular materials. To develop the concept of design guide, the weighted score by linear transformation ranked the overall performance of those geometries, and the paired comparison was used for understanding potential sacrifices. As a result, when the opening was south-facing, the louvers worked better than the perforated screen.
