Standards
Built on the Standards
Engineers Trust
HVAKR implements the ASHRAE Radiant Time Series method — the same standards your PE stamp depends on.
What We Validate
Rigorous by Design
Every load calculation follows published ASHRAE methodology, documented against every requirement of Standard 183.
Local Weather & Solar Data
Pulls verified ASHRAE weather data by latitude/longitude for accurate peak load analysis at your exact location.
Envelope Thermal Properties
Incorporates thermal and shading properties of all envelope components — walls, windows, roofs, skylights, and slabs.
Sensible & Latent Loads
Calculates internal sensible and latent loads with full psychrometric rigor, including occupancy, lighting, and equipment.
Peak Load Analysis
Analyzes heat gain throughout the entire year using the ASHRAE Radiant Time Series (RTS) method to determine true peak conditions.
Psychrometric Sizing
Uses system configuration and psychrometrics to determine equipment sizing — no guesswork, no black boxes.
Documentation
