5 Key Factors of Energy Efficient Design
Introduction
UCL Ltd has developed specialist expertise in airtight coating application, a critical component of Passive House and energy-efficient construction. Airtight construction significantly reduces unwanted air infiltration, cutting heating and cooling demand and improving building performance. UCL's work on projects such as the Imperial War Museum Archive Building demonstrates this capability at the highest level.
Our Solution
Achieving Passive House performance requires five integrated design principles: super insulation with continuous coverage and no thermal bridging; airtight construction using membranes, tapes, and specialist coatings verified by blower door testing; high-performance triple-glazed windows and doors with low U-values; Mechanical Ventilation with Heat Recovery (MVHR) systems to maintain air quality whilst recovering thermal energy; and minimal energy demand design incorporating efficient systems and renewable sources. UCL Ltd provides specialist airtight coating installation across all building types, ensuring envelope integrity in line with Passive House and equivalent energy performance standards.
Key Benefits
- Energy savings of up to 90% compared to conventional construction
- Verified airtightness levels achieved through blower door testing
- Reduced heat loss via elimination of thermal bridging and air infiltration
- Improved indoor air quality through controlled MVHR ventilation
- Reduced condensation and humidity-related risks
- UCL-applied airtight coatings contributed to the most airtight building in Europe (Imperial War Museum Archive Building)
Conclusion
UCL Ltd delivers verified airtight coating solutions that underpin Passive House and high-performance building envelopes. Our installation on the Imperial War Museum Archive Building — the most airtight building in Europe — demonstrates our technical capability on demanding, record-setting projects.
