What did the Dublin RetroFit decarbonisation project involve?

The project for two central Dublin office buildings (120,000 sq.ft.) included M&E surveys, baseline BER energy modelling, and research into renewable electricity and heat network connections.

How does HollenPlus establish a baseline for Irish energy performance?

We use energy modelling to establish the current baseline Building Energy Rating (BER), which is the Irish equivalent to the UK's EPC. This allows us to create accurate, data-driven decarbonisation roadmaps.

What role does renewable energy play in your Dublin retrofit pathways?

Our pathways explore opportunities for renewable electricity generation and power upgrades. We actively liaise with the Irish Energy Board to ensure that proposed decarbonisation options are technically viable and future-proof.

Does HollenPlus provide cost advice for Net Zero pathways?

Yes, our decarbonisation roadmaps include detailed cost advice for various options, enabling asset managers to make informed decisions that balance sustainability goals with financial performance.

2025
Decarbonisation Strategy

HollenPlus delivered detailed retrofit decarbonisation pathways for two adjoining office buildings in central Dublin, totalling 120,000 sq.ft. The project involved:

M&E surveys to establish existing systems, age and condition

Energy modelling to find current baseline BER rating (Irish equivalent to EPC)
Research into opportunities such as heat network connections and renewable electricity generation
Liaison with Irish Energy Board to explore power upgrade options
Energy modelling of available options with detailed analysis
NET ZERO Pathway
Detailed cost advice for the available decarbonisation options
Final asset management focused recommendations
