CAworks partners with DERVOSS to bring hydronic radiant cold ceiling systems to luxury residences and premium commercial spaces across the UAE and Saudi Arabia. Zero noise. Zero drafts. Up to 50% lower energy bills.
Zero moving parts in the living space. 0 dB acoustic footprint versus 25–30 dB from VRF fan coils. Sanctuary-level quiet.
Heat absorbed via thermal radiation, not forced air. No temperature stratification, no cold spots, no dry eyes.
No recirculated dust, allergens or mold. DERVOSS FATU provides HEPA + UV-C filtered 100% fresh air supply.
Water carries 3,400× more thermal energy than air. Higher chiller COP at 15–18°C water vs 5–10°C refrigerant.
Panels hidden in standard plasterboard. Under 4 cm profile versus 60 cm duct plenums. Higher ceilings, cleaner walls.
PEX-a piping rated for 50–100 years. No filters to change, no coils to clean, no condensate drains to unblock in-room.
Operates above dew point. No water drains in ceilings, no leak risk, no breeding ground for bacteria.
Aligned with UAE Net-Zero 2050, Al Sa'fat Platinum, Saudi Mostadam, and Kigali HFC phase-down requirements.
Distinct regulatory frameworks, tariff structures, and construction cultures demand region-specific value propositions.
DEWA's progressive slab tariff punishes high usage exponentially — from 0.23 to 0.38 AED/kWh. A 30–50% reduction in HVAC load can drop an entire villa from the Red slab to Yellow, compounding savings.
Dubai's mandatory green building system awards Platinum for 35%+ energy savings, tight envelopes, and superior IAQ. Radiant + DOAS inherently satisfies Articles 501.05 and 502.01 — a direct certification accelerator.
Dubai and Abu Dhabi regularly hit 90% RH. DERVOSS integrated FATU with graphene heat exchanger and compressor dehumidification keeps dew point below surface temperature at all times. Patent-pending controls.
For Palm Jumeirah and Emirates Hills properties at AED 3,000+/sqft, invisible climate control is not a luxury — it's expected. No grilles, no cassettes, no ductwork bulkheads compromising interior design.
Standard ducted VRF requires 60 cm plenum. Cold ceilings need under 4 cm. In high-end villas, this recovers 50+ cm of ceiling height across every room — an architectural game-changer.
While VRF derates at 46°C+ ambient, water-based chillers maintain higher COP in extreme heat. Combined with outdoor radiant panels for terraces, the system performs where others struggle.
Saudi residential electricity jumps from 0.18 to 0.30 SAR/kWh above 6,000 kWh. Large compounds easily exceed this. Radiant cooling's 30–50% efficiency gain keeps consumption in the lower band.
The Saudi Building Code mandates 30% energy reduction by 2030. Mostadam rating system rewards efficient HVAC. Radiant cooling is a direct path to compliance and top-tier certification.
Riyadh regularly exceeds 50°C in summer. VRF compressors derate dramatically. Water-based chiller systems maintain consistent COP, delivering reliable cooling when it matters most.
NEOM, The Line, Red Sea — Saudi's giga-projects demand next-generation sustainable technologies. Cold ceilings align with the ultra-modern, carbon-neutral vision of these developments.
Saudi's sand and dust storms devastate conventional AC filters. Cold ceilings never circulate air. DERVOSS FATU with HEPA + UV-C provides clinical-grade filtration — critical for respiratory health.
Large Saudi residential compounds (1,000+ sqm) face massive cooling loads. Decentralised DERVOSS FATU units eliminate single-point-of-failure risk inherent in central chiller/AHU systems.
A direct performance comparison across every dimension that matters.

Estimate the total cost of ownership advantage of DERVOSS cold ceilings versus VRF for your property.
DERVOSS performs a precision 3D scan of your property to map thermal loads, envelope performance, and architectural constraints.
CAworks engineers a bespoke cold ceiling layout — ceilings, walls, and floors — with integrated FATU placement for dehumidification.
PEX-a piping is embedded in Knauf drywall profiles. FATU units are positioned. Hydronic circuits are pressure-tested and commissioned.
DERVOSS control system is calibrated: CO₂, humidity, dew point sensors linked. BMS integration (KNX/BACnet) ensures autonomous operation.
