Project
Overview

The Keck Institute for Space Studies at California Institute of Technology in Pasadena brings great minds together for collaboration. WRL provided engineering and sustainability consulting for Lehrer Architects. The 7,000-sf compound is composed of a new and a renovated historic building. The existing 3,300-sf building was built in 1925. The historic significance builds upon associations with Dr. Tolman, Dr. Bacher, Mrs. Ruth Tolman, and Dr. Albert Einstein.

The Keck Institute for Space Studies at California Institute of Technology in Pasadena brings great minds together for collaboration. WRL provided engineering and sustainability consulting for Lehrer Architects. The 7,000-sf compound is composed of a new and a renovated historic building. The existing 3,300-sf building was built in 1925. The historic significance builds upon associations with Dr. Tolman, Dr. Bacher, Mrs. Ruth Tolman, and Dr. Albert Einstein. The residence retains almost all of its original integrity today as a single-story, stucco-clad house, with red tiles cover pitched roof, and exposed beam ends. A variable refrigerant system allows for energy recovery between zones ideal for the existing east/west dominate exposures, while the routing of small refrigerant piping allows for minimum impact to the historic fabric of the existing building. The new one-story annex building erected adjacent to the existing building structure totals 3,800-sf. The new building provides a large meeting space and lounge, as well as additional office space. The design employs a hybrid of active-mechanical and passive systems. To promote passive cooling and natural ventilation, operable windows and clerestories are positioned to induce cross-flow and stack type ventilation. CFD analysis early in design allowed for optimal placement of building apertures. Interior lighting incorporates low mercury type T8 lamps or LED. Lighting controls are based on occupancy sensing for interior lighting, and photocells for exterior lighting. Photometric analysis was used to tune fenestration performance and lighting placement. Electrical sub-metering is integrated with the building management system, to allow monitoring of energy end uses. The building was occupied at the start of 2014 and WRL plans to monitor the operation of the building through 2016. less

Building simulation was utilized throughout the design process, to allow for proper evaluation of energy and water use reduction measures. The relatively dry climate, with good diurnal temperature swings, allows a mixed-mode ventilation strategy to be employed. Computational fluid dynamics analysis was used to fine-tune the placement of apertures for both cross and stack ventilation.
