How to apply

When selecting HVAC components or systems, use or develop tools that provide embodied carbon estimates and indicate the level of uncertainty associated with these figures.

Project actions

01When researching materials for your design, look for embodied carbon data and consider how reliable that data is.
02If you're designing a system, think about how different choices might impact the overall embodied carbon.

Method & Evidence

DVAccuracy and computational efficiency of embodied carbon estimation, uncertainty quantification.

CVType of building services system (e.g., HVAC components), life cycle stage considered.

Strengths & Limitations

Strengths

+Introduces a novel application of AUP for embodied carbon estimation in building services.
+Compares AUP with Monte Carlo simulation, providing practical insights into computational efficiency.

Limitations

Gathering precise data on the exact materials and quantities used in manufactured building services components can be challenging.

Reliability & validity

The study's validity is supported by empirical case studies and comparison with Monte Carlo simulation. Reliability would depend on the consistency of the estimation method when applied to different systems or datasets.

Think critically

How might the 'choice mechanisms' used by designers influence the adoption of embodied carbon information, even if accurate data is available?

Design Principles

"Embodied carbon assessment should be a quantitative, uncertainty-informed component of early-stage design decision-making for building systems."

Designers and engineers often lack robust methods and data to assess the environmental impact of building services. Developing tools that can estimate embodied carbon, even with limited source data, empowers informed decision-making and can lead to more sustainable building outcomes.

What This Means for Your Design

This research shows how to figure out the environmental 'carbon cost' of the parts that heat, cool, and ventilate buildings, even when you don't have all the exact details. This helps designers pick options that are better for the planet early on.
