Architectural & Structural Vision
In collaboration with RTS and its architectural partners, we have refined a unified vision for a high-efficiency chapel that blends sacred-modern design with state-of-the-art construction techniques. Our shared goal is to build upon the existing architectural intent, enhancing it with systems that provide resilience and long-term value.
Architectural rendering of the intended sacred-modern interior with prefabricated structural arches.
I. Architectural Vision & Envelope
- Design Intent: A 400-seat sanctuary with vertical sacred symbolism and a hybrid modern-traditional aesthetic.
- Core Philosophy: Emphasis on prefabrication for quality control, efficiency, and speed of installation.
- Wall Assemblies: 6½" to 8¼" Structural Insulated Panels (SIPs) with a minimum R-26 insulation value.
- Roof Assemblies: 10¼"+ SIP roof panels (R-38+) designed to integrate seamlessly with the structural system.
- Foundation: An enhanced conditioned basement plenum that houses all mechanical systems and provides integrated storage and geothermal efficiency.
II. Key Materials & Interior Program
- Structural System: Prefabricated, architectural-grade glulam arch trusses or an approved structural equivalent.
- Exterior Finish: A combination of painted Hardie Plank vertical battens and a cultured stone veneer base.
- Interior Spaces: Sanctuary, Foyer, Pastor's Office, Nursery/Bridal Suite, and Restrooms.
- Interior Finishes: LVT flooring, porcelain tile in wet areas, and stained-grade wood finishes on exposed structural elements.
- Aesthetic Elements: Gothic-style window units and an optional prefabricated steeple.
Advanced SIP Technology for Demanding Spans
The chapel's design, with its beautiful, open sanctuary, involves long roof spans that require an advanced approach to structural integrity. To meet these demands efficiently, we utilize our patent-pending **FIRM (Fully Integrated Reinforced Modular SIP) system**. This method embeds structural reinforcement directly into the SIP core, allowing us to achieve the necessary strength for long spans without relying on bulky secondary framing, thus preserving the open, sacred aesthetic.
Further technical details and specifications for this proprietary system are available upon request.
A Note on Material Sourcing & Value Engineering
For all specified materials and systems, including the structural trusses, roofing, and finishes, we are committed to a thorough sourcing process. We will diligently research and present the best available options to ensure the final selection represents the optimal mix of aesthetic quality, long-term durability, and cost-effectiveness for RTS.
Acoustic Design Process
Acoustic Executive Summary
This chapel design treats the building structure itself as the primary acoustic system, minimizing the need for extensive sound treatments or costly electronic systems. The design process uses computational modeling to test how sound will behave in the space *before* finalizing structural details, aiming for natural sound quality appropriate to worship while leaving flexibility for targeted enhancements.
Design Process
- Computational Modeling: Test voices and music to identify issues early.
- Analysis of Building Elements: Evaluate the acoustic contribution of each component.
- Design Refinement: Adjust geometry based on modeling results.
- Professional Validation: Engage a licensed acoustician to review and validate the approach.
- Final Structural Design: Proceed with engineering after acoustic validation.
Architectural Elements with Acoustic Functions
- Basement Plenum: Acts as a large-volume bass management system.
- Variable Wall Thickness: Creates subtle sound diffusion effects.
- Decorative Grilles: Serve dual ventilation and acoustic functions.
- Steeple Base Geometry: Contributes to sound distribution.
Key Deliverables
- Design Framework: Building geometry options optimized for acoustic performance.
- Validated Specifications: Professional review and recommendations from an acoustician.
- Performance Predictions: Expected acoustic measurements (RT60, STI).
- Construction Details: Critical instructions for builders on acoustic elements.
Risk Considerations
Starting construction without this analysis risks poor speech intelligibility and the need for expensive retrofit sound systems, negating the benefits of an integrated design.

Roofing & Integrated Solar System
The Integrated Solar Roof Concept
Rather than a traditional roof with separately mounted solar panels, this proposal integrates the solar generation directly into the roofing material itself. This approach transforms the entire chapel roof into a discreet, high-performance energy generation system that maintains the aesthetic integrity of the sacred architecture.
Recommended Technology: GAF Timberline Solar™
The GAF Timberline Solar™ shingle is the recommended solution. It is the world's first nailable solar shingle, which allows it to be installed with the same methods as a traditional asphalt shingle roof. This simplifies installation, reduces costs, and ensures a durable, weather-tight seal, all while providing significant power generation.
- Power Output: 57W per shingle from monocrystalline PERC solar cells.
- Durability: Carries a 25-year warranty and is rated for 130 mph winds.
- Installation: Nailable design allows for installation by any GAF-certified roofer.
- Aesthetics: Blends seamlessly with traditional asphalt shingles for a uniform look.
The integrated solar roof maintains the chapel's traditional aesthetic.
Power Generation Potential for RTS Chapel
Chapel Roof Area: Approximately 6,510 sq ft
Estimated Usable Solar Area: ~5,500 sq ft
GAF Timberline Solar Scenario
- System Capacity: ~1,100 shingles × 57W = ~63 kW system
- Annual Production: ~82,000 - 95,000 kWh
- Emergency Power: 48+ hours of independence (with compatible battery storage).
- Potential: Can cover all chapel operations plus provide significant emergency reserve capacity.
Note: These are preliminary estimates. A professional solar assessment is required for a final, precise projection.
Implementation & Partnership
In line with RTS's vendor selection, we will partner with dGEN Energy Partners, a specialist in commercial and industrial solar, to oversee the system design and ensure a seamless, professional installation. This collaboration ensures that the project benefits from deep industry expertise in both roofing and solar energy systems.
HVAC + Plenum Systems
Advanced Conditioned Plenum with Geothermal Integration
The conditioned basement plenum leverages North Carolina's consistent ground temperatures (45-55°F) to provide highly efficient climate control.

🔇 Ultra-Quiet Operation
- All mechanical equipment is housed in the isolated basement plenum.
- Oversized plenum allows for ultra-low air velocity, eliminating noise.
- Engineered for a target noise level of <25 dB (inaudible library quiet).
- Vibration isolation prevents sound transmission through the structure.
🛡️ Emergency Reliability
- Maintains a livable 50-60°F comfort zone even during a power outage.
- Protects generators and batteries in a secure, conditioned space.
- Provides ideal cool-storage conditions for emergency food and water.
