Services Offered in Precision Load Analysis
1. Detailed Zonal and Hourly Load Calculations
- Service: We perform complex, granular calculations to determine the precise instantaneous heating and cooling loads for every individual zone (e.g., offices, server rooms, lobbies) within the facility for every hour of the year.
- Value: This goes beyond simple block-load estimates to capture the complex thermal dynamics, ensuring the resulting energy model and HVAC design are based on real-world, dynamic requirements.
2. Comprehensive Building Parameter Establishment
- Service: We establish and model all non-HVAC factors that drive the load calculation:
- Envelope Analysis: Thermal properties of walls, roofs, windows, and infiltration rates.
- Internal Gains: Detailed modeling of heat generated by occupants, lighting density, and equipment (plug loads).
- Operational Schedules: Exact mapping of occupancy and lighting schedules throughout the day and week.
- Value: Accuracy is paramount. Defining these parameters precisely is essential for successful ASHRAE Calibrated Simulation.
3. "Design Day" Simulation
- Service: We model the facility's performance under extreme design conditions (e.g., the hottest summer day or the coldest winter day for that specific climate zone).
- Value: This confirms the peak sizing requirements, preventing the selection of undersized equipment (which leads to failure) or oversized equipment (which leads to inefficiency, short cycling, and higher capital cost).
4. Direct HVAC System Sizing Input
- Service: The precise peak load outputs from the analysis are directly used to inform the selection and sizing of all proposed HVAC components (e.g., chillers, boilers, air handlers, VRF systems).
- Value: Guarantees that the proposed HVAC systems are optimized for performance and initial capital expenditure, aligning with local code requirements that often penalize oversizing.
5. Compliance Documentation
- Service: The documented load analysis outputs (design heating/cooling loads, design day temperature profiles) are included in the final technical reports.
- Value: Provides the necessary engineering proof to comply with codes like ASHRAE 90.1 and IECC, demonstrating the HVAC system is correctly sized and designed for efficiency.
