Sometimes the world outside is too grey — especially in November. We solve this with Color-Correcting Glass: electrochromic 'smart' windows that act like photo-editor filters, making the lobby view sunnier, higher-contrast, or more futuristic depending on time of day and weather. Reception Space has deployed this technology since 2023 in projects ranging from 40 m² boutique lobbies to 800 m² class-A+ business-centre facades. Panels start at $1,500 per m² and pay for themselves within 3–5 years through HVAC savings and higher rental premiums.
Architectural Filters
We use glass with an SPD (Suspended Particle Device) or EC (Electrochromic) layer that changes colour and light transmittance on a controller signal. Switching time ranges from 30 seconds to 3 minutes depending on panel area. On a gloomy autumn day the lobby glass enters 'Amber-Soft' mode, tinting daylight to warm 2700–3000 K hues. The psychological effect is comparable to a sunny afternoon — guests report an instant mood lift.
A reception desk positioned by such a window always appears perfectly lit — daylight is 'edited' in real time. Leading manufacturers include View Smart Glass (USA), SageGlass (Saint-Gobain), and Halio (Gentex), each offering 10+ year warranties on the electrochromic layer.
Visual Zoning: Tint-on-Demand
Using smart glass we create coloured 'frames' within the lobby panorama. A café zone bathes in pink or peach tones, boosting appetite by 15–20 % according to behavioural research. A coworking zone receives a restrained blue that raises concentration and productivity by 8–12 %. This manages human behaviour without partitions or signage — architecture as neuro-influence.
Lobby finishes are deliberately selected in neutrals — grey, white, beige — to serve as a perfect canvas for the shifting window palette. Integration with BMS (Building Management System) enables automatic switching by light sensors, time of day, weather, and even the event calendar. Supported protocols include Modbus, BACnet, and custom APIs.
Protection and Privacy: UV Blocking
Beyond colour, this glass blocks 99 % of UV radiation, protecting expensive furniture, carpets, and artwork from fading. Air-conditioning savings reach 20–30 % thanks to reduced solar heat gain (SHGC 0.09–0.41 depending on state). Energy consumption is minimal — only 2–5 W/m² during state change; maintaining a set colour requires virtually zero power.
PDLC (Polymer Dispersed Liquid Crystal) glass can switch to fully opaque in fractions of a second, ensuring event confidentiality. This is ideal for penthouses, corporate headquarters, and luxury lobby bars where the window view is part of the product. In the event of a power outage, the panel remains in its last set state — a fail-safe configuration.
Installation and Maintenance
Glass units with an electrochromic layer are manufactured to order in 6–12 weeks. Maximum panel size is 1.5 × 3 m; unit thickness ranges from 24 to 40 mm. Mounting follows standard curtain-wall procedures — the only addition is a 24 V DC power feed per panel. Routine maintenance is ordinary window cleaning with no special requirements.
The electrochromic layer is rated for 50,000+ switching cycles and 20+ years of service. Controllers can be replaced without removing the glazing unit. Retrofit solutions — replacing panes in existing frames or applying PDLC overlay films — are 30–40 % cheaper, making smart glass accessible even for heritage buildings undergoing modernisation.
