In early 2023, a multinational logistics firm managing a 22,000 m² distribution warehouse in Eastern Europe approached us for a building envelope retrofit. The structure, originally completed in 2010, used insulated sandwich panels but lacked any external shading or ventilation. With rising internal heat loads from automated picking systems and summer ambient spikes, interior temperatures breached safe operating limits, impacting uptime and inflating cooling costs.
The façade audit revealed over 70% of solar gain originated from unshaded west-facing walls. Metal cladding showed signs of thermal fatigue and delamination. HVAC systems were overburdened despite zoned ducting. More critically, poor ventilation created condensation along the inner wall cavities. Our engineering team concluded that the wall system required a full upgrade using external solar deflection and passive ventilation technologies.
We proposed a dual-component retrofit: a radial aluminum sunshade system and modular minimal vent panels. The Metal Sunshade and Minimal Vent Cladding set combined functionality with industrial aesthetics. Design considerations adhered to ASTM E90 sound transmission standards and ISO 6946 heat resistance guidelines. Sunshades were configured in a cascading pattern with offset mounts, while vent panels offered laminar airflow via micro-perforations.
Sunshade projection: 600mm from wall face
Material: PVDF-finished Grade 6061-T6 aluminum
Vent cladding: 2mm anodized aluminum, open area 15%
Mounting: stainless steel Z-clips, anti-corrosive sealed anchors
Air gap: 50mm cavity for stack-effect air channel
Interior summer temperature reduction: 12.3°C
HVAC operating time reduced by 34%
Monthly energy cost dropped by €3,900
Interior condensation eliminated (validated by ASA reports)
Compliance with ASCE envelope integrity standards
Over six weeks, 3,200 square meters of vented panel and sunshade array were installed. Installation crews worked during non-peak shifts to avoid disrupting logistics operations. The client’s facility management reported significant reductions in equipment overheating alarms and cooling compressor faults. Architectural Digest highlighted the retrofit as part of their “Industrial Sustainability 2024” feature.
