Empirical Cases
PRMS in
Practice
Theory becomes architecture. Applications of the PRMS framework across residential, building, and urban scales — from built prototypes to active research cases.
Primary Case Study
SmartLiving Milenio III
The empirical foundation of the PRMS framework. A residential prototype designed, built, and instrumented to demonstrate all four metabolic layers in continuous operation.

Scale: Vivienda
Residential applications
At residential scale, PRMS operates through the SmartLiving Home™ system — a set of design, construction, and instrumentation protocols derived from the Milenio III prototype.
SmartLiving Home™
The residential implementation of PRMS. A modular system based on the 3.60 × 7.20 × 3.60 m base module with four integrated metabolic layers. Designed for replicability and measurability from day one.
Renewable PEAR™
The energetic subsystem of SmartLiving. Integrates photovoltaic generation, battery storage, smart metering, and grid-interaction management within the PRMS energetic layer protocol.
OH-Design™
The spatial configuration methodology. Derives form and program from the metabolic logic of the building — applying Principle III (energy-first design sequence) at residential scale.
PEAR-ROI™ Indicator
The performance score calculated from the first year of operational data. The primary validation instrument for SmartLiving Home™ performance claims.
Scale: Ciudad
Urban metabolism applications
PRMS at urban scale is an active research line. The framework's scale-invariant logic makes it applicable to districts, corridors, and territorial systems — with KPI calibration specific to each level of aggregation.
-
Territorial Metabolism Mapping
Application of PRMS metabolic flow analysis at district scale — identifying energy surplus nodes, water recovery potential, and ecological connectivity corridors within urban fabric.
-
Node Network Design
Design methodology for clusters of PRMS residential nodes that exchange surplus flows — approaching collective Regenerativo performance through networked autonomy.
-
Urban Policy Integration
Research into how PRMS metrics can inform urban development regulations — replacing prescriptive building codes with performance-based thresholds calibrated to local metabolic conditions.
Design with PRMS
PRMS is the framework. PEAR-ROI Studio Architects is the implementation entity. If you are interested in designing a building that operates as a metabolic system, visit the studio.
