Overview

ISO 52016-3:2023/Amd 1:2025 is an important amendment to the ISO 52016-3 standard, focusing on the energy performance of buildings. This document elaborates on the calculation procedures for adaptive building envelope elements, specifically concerning dynamic solar shading and chromogenic glazing-advanced technologies used to regulate solar heat gain and visual comfort within buildings. Published by ISO in 2025, this amendment introduces reference control scenarios designed to standardize the evaluation of these adaptive building components, thus improving the accuracy and consistency of energy needs calculations for heating and cooling.

Key Topics

Adaptive Building Envelope Elements: The amendment covers calculation methods related to adaptive elements such as venetian blinds, roller blinds, shutters, and chromogenic glazing which respond dynamically to environmental conditions.

Dynamic Solar Shading: Solutions that adjust shading devices in response to solar radiation levels in real time, optimizing energy consumption by reducing unwanted heat gains or losses.

Chromogenic Glazing: Windows with glazing that alters its properties (e.g., tint or transparency) dynamically to control solar heat gain and daylight, enhancing occupant comfort and energy efficiency.

Reference Control Scenarios: Detailed control strategies for both manual and automated operation of shading and glazing systems, including variations by space type (residential, office) and occupant behaviors (manual overrides, automated controls).

Calculation Corrections: Adjustments reflecting occupant interventions and behaviors, delayed responses, and control intervals to provide realistic modeling of building envelope performance.

Performance Metrics: Includes considerations for internal temperatures, sensible and latent heat loads, and daylight levels, all critical in assessing energy demand related to heating and cooling.

Applications

Building Energy Modeling: This amendment supports precise and standardized modeling of building envelope dynamics when designing or retrofitting buildings to improve thermal comfort and energy efficiency.

Architectural Design and Simulation: Architects and engineers can apply these procedures to simulate the impact of adaptive shading and glazing on building energy use, informing design decisions and material selection.

Building Automation Systems: Developers of smart control systems for HVAC and shading devices can use the reference control scenarios to align system behavior with standardized performance expectations.

Energy Performance Certification: Facilitates compliance with energy codes and sustainability certifications by providing robust calculation methods for assessing adaptive envelope elements.

Occupant Comfort Optimization: Modeling occupant behavior interventions in shading adjustments allows for a better understanding of real-life impacts on energy consumption and comfort levels.
