BREEAM Impact of refrigerants

Contents

[edit] Aim and benefits

To reduce the levels of greenhouse gas emissions arising from refrigerants leaking in the development.

[edit] What's the problem with refrigerants?

[edit] When to consider

At the pre-assessment, it's useful to establish:

- Will there be refrigerants? Will they likely have more than 6kg charge in each unit?

- Are there any plans to use a very low GWP refrigerants?

- Are we planning to have chillers? or a VRF system?

[edit] Tips and best practice

Frequently, your M&E engineer may well nod along that these credits are all achievable. Please consider:

- DELC <100 or GWP <10 -- Unless you're using a "strange" system with refrigerants such as ammonia, water -- you probably won't achieve these credits. Less than 1000 however, is relatively OK if you use R134a/R32 or something similar.

- You probably (as of Jan 2018) won't find a leak detection system for a VRF system, only if you have centralised chillers.

[edit] Applicable Schemes

The guidelines collated in this ISD aim to support sustainable best practice in the topic described. This issue may apply in multiple BREEAM schemes covering different stages in the life of a building, different building types and different year versions. Some content may be generic but scheme nuances should also be taken into account. Refer to the comments below and related articles to this one to understand these nuances.
