StudioK1, working with architects Pacific Design Group and Hong Kong-based interior designer Joey Ho, has taken a historic hotel from the 1930sand given it a radical, contemporary twist. The DusitD2 Hotel Constance in Pasadena has opened to much fanfare, revitalizing the eastern end of Colorado Boulevard and bringing new life to a faded glory. tk1sc also provided electrical engineering services on this project.

Our team was brought on board to help transform this California Spanish Deco hotel. The building had fallen into disrepair but has been given new life as a cutting-edge boutique hotel. Its historic status, along with California’s stringent Title 24 energy code, made the renovation a challenge. Still, we met these challenges with high efficacy luminaires, controls, and alighting design elegant in its simplicity. Although the exterior remained intact, We completely renovated the interior into a playful juxtaposition of historical and contemporary.

With most of the hotel using high-efficacy luminaires, a few key areas can take advantage of the warmth and feel of incandescence and still have the overall project fall well below Title 24. A central control system helps maintain lamp life and reduce energy consumption.

The preserved corbelled ceiling of the lobby allows limited opportunities for penetration. Lighting is provided not from downlights but sconces and LED luminaires integrated into the seating.

‍

Guest rooms are illuminated almost entirely with LED luminaires. Recessed ceiling luminaires are eschewed in favor of cove lighting and wall-mounted task lighting to maintain maximum ceiling height within a limited floor plate. Flexible LED linear luminaires allow for a celebration of the organic forms of the interior design.

Corridors are illuminated by T5 linear fluorescents behind decorative ceiling panels, with limited plenum depth, the decorative pattern aids in masking shadows from mechanical systems. Linear LED delineates the curvilinear wainscoting.

The lobby bar offers a playful intensity of color and curved forms, delineated by linear LED lighting. Downlights are LED, making the relaxed environment energy efficient, as well. The chandeliers in the main lobby corridor evoke the past, providing an eclectic mix of old and new.
