2. The Research Support Facility (RSF) is a very
significant building for DOE and NREL (National
Renewable Energy Laboratory). The building is a
showcase of sustainable high-performance design. It
demonstrates the integration of high performance
design features and practices, showcases technology
advances, and captures the public’s imagination for
renewable and energy efficient technologies.
The Research Support Facility
(NREL)
Location - Golden Colorado (24 miles west of Denver).
Architects: RNL Design
Area : 222000 ft²
Year : 2010

3. Strategies
The building is a simple architectural response to the climate,
site, and ecology that envelop it and the desire for a flexible,
high-performance workplace within.

4. Building and Energy Diagram
The building is shaped around the climate to optimize passive energy
strategies. The 60' wide section for the main office wings was driven by
the objective to daylight and naturally ventilate the main office wings.
The narrow footprint results in two long office wings oriented along
the east/west axis and linked by a central connector space consisting
of the lobby and conference facilities. This building begins to hum as
soon as the sun hits it, which is ideal given the number of sunny days
in Colorado. The building creates its own electricity, heats its own
ventilation air with a transpired solar collector, and shades all windows
during the summer while providing an exemplary daylit space all year
round

5. Materials
One key strategy employed was the use of modular construction.
The exterior wall is composed of insulated precast wall panels with
finished interior and exterior surfaces. The other key strategy was to
optimize the amount of glass and therefore not over-glaze the main
office wings. The optimization of the glazing allowed cost control
and solar gain control while maintaining fully daylit office spaces.
The material choices for the building were driven by the
desire to have flexible and durable materials with low health
impacts and reduced resource consumption.

7. Walls and Windows
Dynamic Glazing
- E-W elevations feature thermo-chromic>> reduce heat loss and electro chromic glazing>> reduce heat gain

8. Below grade System
Labyrinth Thermal Storage
-Air heated by the transpired solar collector heats the thermal mass >> preheats ventilation air.
-The labyrinth can warm outside air by 5–10°F.

12. Lighting
Sensors
Occupancy sensors control the amount of artificial lighting used.
Lights are activated only when someone enters a room.
Additionally, light intensity is adjusted according to daylight
levels.
When there is abundant daylight, artificial lights are
automatically dimmed.
Temperature and ventilation rates are also adjusted with
occupancy sensors, according to the number of people using the
space
HVAC System
Energy-efficient air-conditioning: The system detects carbon
dioxide levels and lowers fan speed, and thereby ventilation
rates, when fewer people are around.
Floor diffusers: These supply cool air, which, once warm, will
rise toward vents in the ceiling and exit the building.
Personalized ventilation: Cooling supply around each desk is
adjustable according to individual needs.

13. Walls
Green Walls
• Unusual Aspects and Aesthetic Values
• Approx 50% of green wall and 43% glazing

14. Windows
• High Thermal Performance Glazing - Double Glazed Unit
• Sun Shades with PV
• Low-e glass
