Off-site Structure Metal Sunshade and Semi-Enclosed Vent Systems – Modular Climate-Control Solution for Remote Facilities

ModuBuild Engineering, a prefabrication contractor serving energy and logistics sectors, developed an innovative approach to thermal regulation in remote service units. Many off-site facilities such as telecom shelters, field control stations, and modular substations face dual environmental challenges — extreme solar gain and limited natural ventilation. The company introduced a metal sunshade and semi-enclosed vent system designed to achieve passive thermal balance without mechanical energy use.

1. Background: Environmental Stress in Remote Modular Units

Off-site prefabricated buildings often rely on lightweight insulated panels that trap heat and moisture. Under direct sunlight, temperatures inside these enclosures can rise 20–30 °C above ambient levels. Mechanical cooling systems are costly, requiring frequent maintenance and energy consumption. The ModuBuild team aimed to integrate passive airflow geometry and solar shielding within structural panels to provide year-round temperature stability.

2. Design Objectives

• Reduce internal temperature peaks by ≥ 15 °C during midday exposure.

• Enable cross-ventilation in semi-enclosed layouts with limited openings.

• Minimize power demand for HVAC or fans by ≥ 50 %.

• Use corrosion-proof, easy-to-install modular components.

• Adapt system to variable site orientations and climates.

3. Engineering Approach: Metal Sunshade + Semi-Enclosed Vent Combination

The system features perforated aluminum sunshade panels (open area 34 %) combined with vertical semi-enclosed vents that form a protective airflow corridor. Each vent incorporates angled louver geometry (22°) with internal mesh layers to block dust and insects. The facade spacing (80 mm cavity) stabilizes pressure, enabling natural convection while preventing drafts. Panels are modular, attached via quick-lock brackets to minimize on-site assembly time.

4. Field Measurements and Results

Testing was conducted on six off-grid power shelters in desert regions. Results demonstrated significant performance improvements:

• Average internal temperature drop: 16.8 °C compared to baseline enclosure.

• Relative humidity stabilization: 55–60 %.

• Power savings: 48 % reduction in HVAC runtime.

• Dust ingress reduced by 71 % via double-layer vent screens.

• Installation time per module: 3.5 hours average.

5. Maintenance and Durability

After 18 months of deployment, no corrosion or mechanical failure was recorded. Panels retained original coating quality, and the semi-enclosed vents required cleaning only twice per year. The structural integrity remained stable under 35 m/s wind loads. The aluminum alloy (6063-T6) combined with PVDF coating provided maximum weather resistance.

6. Lessons Learned

• Partial enclosure design achieves ideal balance between airflow and protection.

• Vertical vent orientation improves cross-ventilation in compact units.

• Micro-perforations prevent heat layering under direct radiation.

• Durable coatings minimize maintenance for remote installations.

• Modular clip systems reduce installation cost and error risk.

7. Conclusion & Engagement

The off-site structure metal sunshade and semi-enclosed vent system enables remote facilities to maintain comfort and durability with minimal power consumption. It transforms prefabricated buildings into self-regulating microclimate enclosures suitable for telecom, energy, and emergency service operations.
