Daylighting, Sun Shading & Views: Polycarbonate skylights, wood sun screens, and interior roller shades all work together to introduce, reflect and control natural day light. These components were strategically employed to satisfy foot candle minimums, tackle glare, and enhance views, resulting in a pleasantly lit interior environment.

Building Envelop

Orientation:

The design team orientated the building to face south and elongated the east–west axis to increase the use of natural light.

Space Layout:

The layout of the spaces was also designed with the orientation to arrange natural daylight more appropriately, which allow more natural daylight into the interior space to provide appropriate illuminance.

Use large exterior south-facing windows with trellis design and high ceilings to increase daylighting. Clerestory designed to optimize daylighting. Skylight on the north part also provide a stable illuminance level for working and studying.

Shading:

Install adjustable interior shading devices to reduce glare; Adjustable interior shading devices have been installed to manage glare in the winter months in the south lighting zones.

Window and Shading Detail of Building

Shading Panel on the west facade:

The shading panel fixed on west facade can protect the illuminance comfort from glare in the afternoon.

Block the West Solar Radiation

Materials:

Use Solarban 60 double insulating glass (Low-e glazing ) to keep the same illumination while reduce the solar heat gain and UV energy.

Windows also placed “strategically,” with reflective surfaces to help with light reflectance. The visible transmittance of windows on north and west is higher than that of south and east facing windows.

Glazing Function in Energy Lab

Interior Design

－Use LED or other energy-efficient lighting fixtures.

－Lighting Control Systems

－Use occupancy sensors –motion sensing lights

－Use on/off photoelectric daylight sensors, which are overridden by occupancy sensors when enough daylighting is available.

Light:

Use ELLIPTIPAR (The premier Asymmetric Architectural Lighting manufacturer made in the USA. High performance lighting for the ceiling, wall, floor or ground with unmatched uniformity.)

Patented refractive optics create a uniform plane of light-free of scallops and striations. DLC qualified, integral universal voltage driver, shallow plenum depth of 2-3/8” , illuminates the wall uniformly. Available in 2700K, 3000K, 3500K or 4000K with CRI>80. Luminaire efficacy of 50.4 lumens per watt.

Visible Transmittance

The advanced low-e coating of Solarban 60 glass transmits more than 70 percent of the sun’s available light into a home while blocking 79 percent of the sun’s damaging UV energy and other contributors to fading—in all, 24 percent better than standard clear insulating glass.
