Shanghai Fengxian JW Marriott Hotel Exterior Wall Engineering Project

Project Overview

Project Name: Shanghai Fengxian JW Marriott Hotel Curtain Wall & Decoration Engineering
Service Period: 2018-2020
Project Type: Five-Star Resort Hotel
Service Scope: Integrated Solutions for Metal Curtain Walls, Stone Curtain Walls, and Energy-Efficient Window Systems

Project Background & Core Challenges

As the first international luxury resort hotel in the Fengxian area, the JW Marriott Hotel's facade design integrates modern aesthetics with natural landscape elements, presenting three core challenges:

1. Balancing Aesthetics and Functionality – Achieving seamless integration of curved architectural forms with high-performance curtain wall systems
2. Durability in Coastal Environment – Addressing corrosion challenges from high salt mist and humidity near Hangzhou Bay
3. Integration of Indoor and Outdoor Experiences – Maximizing scenic views while ensuring energy efficiency and comfort

Jixiang Building Materials Solutions

· High-performance Window Wall System: Ultra-narrow frame design maximizing panoramic views

2. Specialized Protection for Coastal Environments

· Anti-corrosion Treatment: Aluminum profiles treated with fluorocarbon spray + anodizing composite process, passing 3000-hour salt spray test
· Waterproof and Breathable System: Three-layer waterproof design ensuring airtightness while allowing internal moisture release
· Typhoon Resistance Design: Curtain wall system passed dynamic wind pressure testing, meeting coastal area wind resistance requirements

3. Energy Efficiency and Comfort Optimization

· Energy-efficient Glass Configuration: Triple silver Low-E insulating glass with 65% visible light transmittance and solar heat gain coefficient ≤0.3
· Thermal Break Design: All metal connectors equipped with nylon thermal insulation pads, improving overall thermal performance by 40%
· Noise Control: Curtain wall system achieves Rw 45dB airborne sound insulation, ensuring quiet guest room environments

Technical Highlights and Innovations

1. Digital Construction Technology

· Full-cycle BIM Application: BIM collaboration throughout design to installation, reducing on-site changes by 35%
· Prefabricated Assembly Construction: 85% factory prefabrication of curtain wall units, improving on-site installation efficiency by 50%
· Drone Inspection System: Utilizing drones for progress monitoring and quality inspection

2. Green Building Technology

· Recyclable Material Application: 90% aluminum recovery rate, 95% stone utilization rate
· Energy Performance: Overall curtain wall system thermal transmittance K-value ≤1.5 W/(㎡·K)
· Water-saving Design: Integration of curtain wall drainage system with building rainwater recycling system
