Dragonboard Technical Due Diligence Portal
Centralised technical repository for structural engineers, principal designers, fire officers, and social housing procurement leads evaluating Dragonboard structural magnesium oxide systems and Dragon I Panel (DIP) Category 2 MMC assemblies[cite: 5].
Section 01 • Practical Deployment Evidence
Documented multi-storey, residential, and social housing schemes delivering verified off-site compliance[cite: 5].
The Lily House, Blaenau Gwent, South Wales
Constructed with 85% Dragonboard across floors, walls, and ceilings. Certified Code for Sustainable Homes Level 5 (15/15 credits Ene 1), EPC Band A (Score 112), 0.37 m³/(h·m²) airtightness, and £242/yr energy costs.
Parkside Place, Warrington
Empirical multi-storey residential delivery validating Dragonboard structural MgO SIPs over ground transfer podium. Class A1 non-combustible envelope with brick-slip rainscreen.
Detached Residential Bungalow, Finchley
200 m² bungalow erected by 2 joiners in 2 days using 175mm slim-profile DIP panels, achieving sub-0.12 W/m²K thermal efficiency, zero cold bridging, and expanded net usable floor area.
Dragon I Panel (DIP) System & Academic Validation
Engineered for ultra-low carbon, rapid-assembly Net Zero housing[cite: 5]. Independent academic research conducted in partnership with the University of Liverpool evaluated the DIP system's thermal transmittance, energy consumption, and occupant comfort across current and projected UK climate scenarios[cite: 5].
0.11 – 0.13 W/m²K
DIP envelopes outperform standard UK Building Regulations Part L (~0.18 W/m²K). 175mm panels achieve 0.13 W/m²K, while 200mm panels hit 0.11 W/m²K, operating well within elite Passivhaus performance thresholds.
2-Year In-Situ Data (Heswall)
University of Liverpool continuous monitoring confirmed internal winter temperatures remained ≥16°C and summer ≤24°C, with indoor relative humidity stable at ~50% without mechanical dehumidification.
Net Zero Operational Carbon
Verified that pairing the airtight Dragon I Panel building envelope (0.37 m³/(h·m²)) with Heat Pumps and Solar PV delivers full Net Zero Energy Building (nZEB) status with zero annual energy spend.
