Smart Glass and Observation Technology
Smart glass technology — glass that can change its optical properties (transparency, tint, reflectivity) in response to electrical signals — represents a transformative capability for observation deck design. For The Mukaab’s spiral tower observation platforms, smart glass creates the interface between the physical viewing position and the holographic dome’s digital environments, enabling observation surfaces that transition between transparent views, tinted privacy modes, and opaque projection screens. This analysis examines the technology landscape, deployment precedents, and engineering requirements for smart glass at Mukaab scale.
Technology Categories
Electrochromic Glass — Uses an electrochromic coating that changes tint when voltage is applied. View Inc. and SAGE Electrochromics (now part of Saint-Gobain) are the leading commercial suppliers, with installations in thousands of commercial buildings worldwide. Electrochromic glass transitions between clear and tinted states over 3-15 minutes, offering variable light transmission from 60% (clear) to 1% (fully tinted). For observation decks, electrochromic glass can manage solar glare, create dramatic lighting effects, and transition viewing surfaces between transparent and tinted states that affect how dome projections appear from observation positions.
Transition speed is the primary limitation for entertainment applications. A 15-minute tint transition is acceptable for office building sun management but too slow for dynamic experience design where scene changes occur in seconds. Current research aims to reduce electrochromic transition times to under 30 seconds through improved coating chemistry and electrode design.
PDLC (Polymer-Dispersed Liquid Crystal) Glass — Switches between transparent and opaque states in milliseconds when voltage is applied. In the opaque state, PDLC glass diffuses light uniformly, creating a translucent white surface suitable for rear projection. Companies like Smart Glass International and Gauzy produce architectural-grade PDLC panels deployed in hotels, hospitals, and retail environments.
For The Mukaab’s observation platforms, PDLC glass offers unique capabilities: transparent mode shows the dome’s holographic environment; opaque mode transforms the glass into a projection surface for localized content (AR information overlays, interactive displays, personalized views). The millisecond switching speed enables dynamic transitions synchronized with dome content changes.
SPD (Suspended Particle Device) Glass — Uses a thin film of suspended particles that align under voltage, transitioning from dark to clear. SPD technology offers faster transitions than electrochromic (under 3 seconds) and variable intermediate tint levels. However, SPD glass in its darkened state is blue-grey rather than neutral, which may affect color accuracy for observation applications where the dome’s projected content should appear with accurate color reproduction.
Micro-LED Transparent Displays — An emerging category where micro-LED elements are embedded within glass panels, creating a surface that can display high-resolution content while remaining partially transparent. Samsung and LG have demonstrated transparent micro-LED panels at CES, with commercial products expected by 2027-2028. For observation decks, transparent micro-LED surfaces could display AR overlays directly on the viewing glass without requiring separate projection systems.
Observation Deck Applications
Smart glass transforms observation deck design from passive viewing to interactive experience:
Dynamic Privacy Zones — Smart glass barriers between viewing positions can create semi-private observation pods within a shared deck. PDLC glass transitions from transparent (social, shared viewing) to opaque (private, intimate viewing) at the touch of a control, allowing couples or families to create private moments within the public observation environment.
AR Information Display — Transparent display glass overlays information on the view — identifying landmarks, displaying distance measurements, providing historical context, or showing real-time data (weather, time in displayed locations, factual information about dome environments). This extends the One World Observatory Sky Portal concept to encompass the entire viewing surface.
Day-Night Transition — Glass tinting can simulate time-of-day transitions independent of the dome’s content schedule. An observation deck could display a sunset scene through darkening glass while the dome maintains a midday environment for ground-level visitors, creating elevation-specific experiences.
Photography Enhancement — Electrochromic glass with anti-reflective coatings eliminates the glare and reflection problems that plague observation deck photography worldwide. The Burj Khalifa’s At The Top decks struggle with window reflections that degrade visitor photographs; smart glass with switchable anti-reflection modes addresses this universal observation deck pain point.
Engineering at Mukaab Scale
Deploying smart glass across The Mukaab’s observation platforms requires addressing several scale-specific challenges:
Power Requirements — Electrochromic glass typically consumes 2-5 watts per square meter in the tinted state and near-zero in the clear state. PDLC glass consumes 5-7 watts per square meter in the transparent state and zero in the opaque state. At observation deck scale (thousands of square meters of smart glass), total power consumption is modest — well within the building’s power budget. However, the power distribution infrastructure (wiring to individual glass panels, control circuits, safety disconnect systems) adds complexity.
Control Integration — Each smart glass panel must be individually addressable by the building’s master control system, enabling zone-by-zone transitions, gradient effects (partially tinted areas creating directional emphasis), and synchronization with dome content. The control network for smart glass panels integrates with the same AI orchestration system driving dome content and spatial audio.
Maintenance and Lifespan — Electrochromic glass has demonstrated operational lifespans exceeding 30 years in commercial installations, with gradual degradation in tinting range over time. PDLC glass has shorter proven lifespans (10-15 years) before replacement of the liquid crystal film is required. At 400-meter elevation, glass panel replacement requires specialized access infrastructure — a maintenance consideration factored into the construction integration timeline.
Cost — Smart glass currently costs $500-1,500 per square meter depending on technology, compared to $100-300 for conventional architectural glass. For observation deck applications where the glass is the product experience rather than a building envelope component, the premium is justified by the experience value delivered to visitors paying $50-150 per ticket.
Comparable Deployments
Willis Tower Skydeck Ledges — The Chicago observation deck’s glass-floored ledges extending from the building face at 412 meters demonstrate how glass engineering creates visceral observation experiences. While not smart glass, the Skydeck’s curved projection system providing flyover simulations shows how glass surfaces serve as both viewing portals and content delivery platforms.
One World Observatory — The Sky Portal’s 14-foot circular high-definition livestream floor demonstrates how digital content integrated into an observation platform surface creates experiences beyond passive viewing. Smart glass could extend this concept to all viewing surfaces.
SUMMIT One Vanderbilt — SUMMIT’s three floors of immersive art use mirrors and glass to create infinity effects that blur the boundary between the physical observation platform and the art installation. Smart glass panels with variable reflectivity could achieve similar effects dynamically, switching between immersive art mode and clear observation mode.

Integration with Building Management Systems
Smart glass at The Mukaab operates not as a standalone feature but as an integrated component of the building’s holistic environment management system. The building management system (BMS) coordinates smart glass tinting with dome content schedule (transitioning glass to presentation mode when dome scenes change), HVAC operation (adjusting tinting for solar heat gain management), lighting systems (coordinating interior lighting with glass transparency levels), and visitor experience programming (activating specific glass configurations for scheduled events or time-of-day transitions).
This integration requires a smart glass control protocol that communicates with the BMS at millisecond latency. Proprietary protocols from different smart glass manufacturers (View’s IntelligenceNetwork, Kinestral’s Halio API, others) must be abstracted into a unified control interface that the BMS can address uniformly. Standards-based protocols (BACnet, KNX, or emerging smart building IoT standards) facilitate this integration but may lack the precision timing required for entertainment-synchronized transitions.
The maintenance and lifecycle management of hundreds of thousands of square meters of smart glass requires predictive maintenance systems that monitor individual panel performance, identify degradation before visible failure, and schedule replacement during maintenance windows that minimize visitor experience disruption. Smart glass panels have expected lifespans of 20-30 years, but in The Mukaab’s demanding environment (high duty cycles, extreme temperature differentials on exterior panels, constant tinting transitions for entertainment zones) actual lifespans may be shorter, requiring a replacement reserve budget and logistics capability.
Strategic Outlook and Forward Indicators
The trajectory of this domain within The Mukaab’s development timeline is shaped by several converging factors. Saudi Arabia’s $196 billion in awarded tourism contracts since Vision 2030’s launch in 2016 demonstrates sustained investment commitment at national scale. The kingdom’s tourism target — 150 million annual visitors by 2030, having already surpassed its initial 100 million target ahead of schedule — creates demand-side pressure for experience infrastructure that The Mukaab is designed to serve.
The New Murabba Development Company’s continued participation in MIPIM 2026 in Cannes in March 2026, following the January 2026 construction suspension, signals that project planning and partnership development continue even as construction timeline adjustments are evaluated. This pattern is consistent with other Saudi megaprojects that have experienced timeline shifts while maintaining long-term strategic commitment.
The $50 billion total investment in New Murabba and the projected SAR 180 billion ($48 billion) contribution to Saudi non-oil GDP position The Mukaab as more than an entertainment project — it is infrastructure for Saudi Arabia’s economic transformation. The building’s 104,000 residential units, 9,000 hotel rooms, 980,000 square meters of retail, and 620,000 square meters of leisure space create an integrated urban economy where immersive technology adds value to every square meter.
For technology vendors, the strategic calculus extends beyond The Mukaab itself. Successful deployment of immersive systems at Mukaab scale creates reference installations applicable to Saudi Arabia’s broader megaproject pipeline — Qiddiya, the Red Sea Project ($10 billion), Diriyah ($62.2 billion), and future projects not yet announced. The global experiential market’s projected growth from $132 billion (2025) to $543.45 billion (2035) at 23.05% APAC CAGR provides the commercial backdrop for long-term technology investment decisions.

Cost-Benefit Analysis for Smart Glass Deployment
Smart glass deployment at The Mukaab involves significant capital cost with measurable returns across multiple benefit categories. Electrochromic glass at $500-1,500 per square meter, PDLC glass at $300-800 per square meter, and SPD glass at $400-1,200 per square meter represent premium prices over conventional glass ($50-200 per square meter). For The Mukaab, with potentially hundreds of thousands of square meters of smart glass across exterior facade, observation platforms, hotel rooms, and retail storefronts, the aggregate smart glass investment may reach $200-500 million.
Returns on this investment flow through: energy savings (reduced HVAC load from dynamic solar management, estimated at $10-30 million annually in Riyadh’s extreme climate), experience revenue premium (observation platforms and hotel rooms with smart glass command 20-40% pricing premiums over conventional glass equivalents), and venue flexibility (smart glass partitions enabling retail and event space reconfiguration without construction, estimated at $5-15 million annually in avoided renovation costs). At these return rates, the smart glass investment achieves payback within 8-15 years — within the expected lifetime of the smart glass technology itself.
Architectural Integration and Aesthetic Design
Smart glass at The Mukaab must achieve seamless architectural integration — the glass must appear as a natural element of the building’s design rather than an obvious technology overlay. When smart glass transitions between states (clear to tinted to projection mode), the transition must feel like a natural environmental change rather than a technical switching event. Color temperature consistency between smart glass panels and adjacent non-smart surfaces prevents visible discontinuities that would reveal the technology to visitors. The Najdi-inspired exterior cladding creates specific aesthetic requirements for exterior-facing smart glass — glass tint colors must complement the cladding material’s natural tones rather than introducing incongruous blue-gray tints (the default color of SPD smart glass). Interior smart glass partitions within hotel rooms and entertainment venues require custom tint profiles that align with the zone’s design palette. This aesthetic integration adds engineering complexity but ensures that smart glass serves the building’s experience vision rather than disrupting it with visible technology artifacts.
