Hong Kong EPD Confirms Broadwell Acoustic Performance, Enabling New Noise Solutions for Construction and Venues

Testing by the Hong Kong Environmental Protection Department at a foundation pit project confirmed that Broadwell’s single-layer air dome can reduce noise by approximately 18 dB, providing standardized, data-backed evidence of its noise-control performance. Broadwell notes that higher-spec dome configurations can achieve 30–50 dB attenuation for entertainment and sports venues. The results highlight air domes as a scalable, sustainable alternative to traditional noise mitigation in dense, noise-sensitive cities such as Hong Kong, Shenzhen, and Shanghai.

January Monthly Newsletter

Broadwell’s latest newsletter introduces DATA DOME, an air-dome center solution designed for faster deployment, stable enclosed environmental control, and scalable expansion in response to AI-driven compute demand. The issue also covers the establishment of Broadwell Korea Co., Ltd., major events hosted at SPIKE Air Dome in Jakarta, an international case study on year-round experience spaces in Turkey, and recent project milestones in Xinjiang and Indonesia.

Air Dome 101 | How Can Global-Minded Companies Quickly Build Overseas Warehousing Infrastructure?

Overseas warehousing is becoming core infrastructure for global expansion — yet companies still face slow permitting, long construction cycles, high costs, tightening environmental standards, and limited flexibility when demand or locations change. This article introduces Broadwell air dome warehouses: a fast-to-deploy, column-free, fully enclosed solution designed to reduce Capex and Opex, improve dust-control compliance, withstand extreme weather, and enable relocation and reuse. It also outlines ideal use cases — from peak-season overflow and bulk-material storage to “storage + processing” facilities and highly regulated industries.

Air Dome 101 | Air Dome vs. Steel Structure: Why Broadwell Costs Less for the Same Ice & Snow Venue?

In this article, Broadwell compares air-supported domes with conventional steel structures for indoor ice and snow venues. Using Broadwell projects as examples, it explains how membrane-based air domes reduce total “build + operate” cost through lower material and civil-work requirements, shorter construction timelines enabled by high prefabrication, and significantly improved energy efficiency. A cost comparison for a 16,000-square-meter ski hall shows a large construction-cost gap in favor of the air dome, while also highlighting added benefits such as earlier opening and more predictable long-term operating expenses.

Broadwell Establishes Korea Entity, Enhancing Localized Overseas Operations

Broadwell Air Dome continues to advance its global strategy by strengthening localized operations and service capabilities in key markets. The establishment of Broadwell Korea Co., Ltd. marks a new milestone supporting faster response and deeper regional coverage across Northeast Asia.

December Monthly Newsletter

Broadwell is revolutionizing modern infrastructure with its new DATA DOME, a fast, sustainable, and modular solution for data centers. Beyond technology, their air dome structures are transforming the entertainment sector, from "naked-eye 3D" immersive spaces in Changsha to high-end luxury events in Jakarta. Key technical milestones include a new patent for pressure-regulating buffer chambers to enhance visitor comfort and the impressive 12-day completion of a Jilin resort project featuring oxygen-enrichment technology. By blending smart management with rapid deployment, Broadwell is positioning air domes as vital, multi-functional infrastructure for the digital, sports, and tourism industries.

Air Dome 101 | Maximizing Comfort and Energy Savings in Air Domes: Broadwell's Solutions for the Middle East

In the intense heat of the Middle East, how can air domes create a comfortable environment while being energy-efficient? This discussion looks at the importance of choosing the right materials, using effective insulation, and optimizing air conditioning systems to keep indoor temperatures between 24–26°C while significantly reducing energy costs. By focusing on high solar reflectance and thermal emittance, Broadwell Air Dome offers a complete solution for sustainable cooling in challenging climates.

Air Dome 101 | More Energy Efficient Than Traditional Buildings? How Air Domes Stay Warm in Winter

Air domes are proving to be more energy‑efficient than traditional buildings during winter operation. Using Broadwell air domes as a reference, this article outlines the main heating options—electric, natural gas, and district heating—and explains how system selection depends on local energy prices, district heating availability, and venue usage.

Air Dome 101 | How Tall Should an Air Dome Be? -- A Clear Guide to Height Design Logic

This article explains how to determine a reasonable height for an air dome and why it matters. Since an air dome’s height decreases from the center to the edges, height directly affects proportions, usability, and structural performance. There is no single standard value, but most projects adopt a peak height between 1/4 and 1/2 of the span. Heights above 1/2 lead to bloated forms and structural inefficiency, while heights below 1/4 create an overly flat profile with poor edge clearances and limited functionality. The article also shows how climate influences height: higher in snowy regions for better snow shedding, and moderately lower in high‑wind areas to reduce wind loads, always based on professional structural and form‑finding analysis.

Air Dome 101 | Why Do Air Domes in the Middle East Need Diagonal Orthogonal Steel Cable Net Systems?

Middle Eastern air domes operate under extreme ground temperatures near 60°C, which severely weaken PVC membranes (strength loss up to 75%) and make welded seams brittle—the structure’s most crack-prone points. A diagonal orthogonal steel cable net system is therefore essential. Acting as a heat-insensitive “skeleton,” the mesh redistributes wind and sandstorm loads from the membrane to steel cables and transfers forces directly to the foundation. It also limits oscillation and strain, protecting vulnerable seams. Unlike simple longitudinal/transverse or basic cross layouts, the diagonal orthogonal pattern provides continuous, omnidirectional load paths and eliminates corner blind spots. In high-temperature regions, this cable system is not a premium add-on but a technical necessity, delivering engineered redundancy, fail-safe safety, and reduced risk for owners.

November Monthly Newsletter

In November, Broadwell launched its Smart Grain Storage Series, featuring the "Grain Cube" for rodent and pest prevention and the "Air Shield" for rapid deployment in small-scale grain storage. Both products utilize advanced technologies to ensure optimal preservation throughout the grain lifecycle. Additionally, Broadwell participated in the C³ Future Building Conference, where Vice President Walker Zhao presented on the sustainability of air dome buildings. The Equatorial Guinea Olympic Committee visited Broadwell's Shenzhen sports complex, and the Spike Air Dome in Jakarta hosted a luxury supercar exhibition, further enhancing Broadwell's reputation in innovative solutions.

Broadwell Showcases at the C³ Future Building Conference · DGNB Sino–German Co-Creation Seminar, Sharing High-Efficiency Carbon Reduction Solutions of Air Domes

At the C³ Future Building Conference and DGNB Sino–German Seminar, Broadwell showcased air dome solutions that deliver high‑efficiency decarbonization under the DGNB framework. Air domes are lightweight, highly prefabricated, relocatable structures that cut material use and on‑site impacts. A 4,000 m² case shows >90% construction‑phase CO₂ reduction (~1,000 tons) and ~430,000 kWh annual energy savings, with OPEX ~70% lower. Broadwell’s 5+ million m² deployments reduce ~10,000 tons of dust and 0.5–0.7 Mt CO₂‑e annually.
