The Research Support Facility (RSF) located on the campus of the National Renewable Energy Laboratory (NREL) in Golden, Colorado, US, has secured LEED Platinum rating from the US Green Building Council.
A team consisting of Haselden Construction and RNL secured the design-build contract for the project.
The $64m building has a total area of around 20,600m² and houses around 800 employees.
The RSF building incorporates several sustainability features and is currently the US’s largest net zero energy building – a building that only consumes as much energy as it produces.
The building orientation and geometry minimises east and west glazing and allows for optimally sized north and south glazing.
Daylight entering the upper portions of the south facing windows is reflected on the ceiling and deep into the space with light-reflecting devices.
A thermal exterior wall made using an insulated precast concrete panel system allows significant moderation of the building’s internal temperature.
Most of the construction materials were sourced locally with around 75% of materials diverted from landfills.
