Passivhaus Social Housing – what’s changed?

Two things: confidence and capacity.

Confidence because early local schemes now have people living in them, with monitoring showing lower bills and better indoor comfort.

Capacity because training—boosted by free designer and trades courses—has expanded the pool of teams who can actually deliver to the standard.

Add to that a growing regional supply chain for airtightness products, MVHR, and low-carbon insulation, and you’ve got momentum that didn’t exist even a couple of years ago.

Passivhaus social housing projects to watch

1. Sunningdale Gardens, Belfast (NIHE):

Six Passivhaus homes—the first MMC Passivhaus-certified social housing in Northern Ireland and the Housing Executive’s first directly delivered new-build in 25 years.

Built with rapid onsite MMC and independently monitored for energy use, indoor air quality, and resident experience.

2. Grove Community Housing Association, Belfast:

Grove Community Housing is a 31-home, mixed-need Passivhaus development from bungalows to family houses.

3. Rathlin Island (Rural Housing Association):

Ten Passivhaus homes shaped by strong resident support during consultation—showing the model works in rural and island contexts.

4. Lakeland Forum Redevelopment, Enniskillen:

On track to be the first Passivhaus leisure centre on the island of Ireland—proof the standard is spreading beyond homes into public buildings.

This local surge mirrors a wider UK-Ireland shift, with major housebuilders and housing bodies committing to sizeable Passivhaus pipelines, including large social programmes now under way.

Why Passivhaus, and why now?

Passivhaus sharply cuts energy demand through a high-performance envelope: super-insulation, airtightness, thermal-bridge-free detailing, triple glazing, and mechanical ventilation with heat recovery. The result is warm, quiet, healthy homes that cost far less to heat—exactly what’s needed in a region still grappling with fuel poverty.

Delivering at scale also supports long-term housing supply goals and climate targets. The social case (health and comfort) and the economic case (lower lifetime costs) are increasingly aligned.

The nagging constraint: funding certainty

Ask providers what still blocks scale and you’ll hear the same answer: financial clarity. Landlords want Housing Association Grant mechanisms to explicitly support higher energy performance, recognising lifetime savings for households and the public purse. The business case is strong—procurement and grant frameworks must catch up.

Skills and certification—bottleneck to backbone

Early schemes ran into thin local expertise, down to a scarcity of certifiers. That’s shifting thanks to targeted training and bigger pipelines pulling more contractors into the ecosystem. The more projects on site, the more teams master the details that matter: airtightness sequencing, component sourcing, commissioning MVHR, and quality assurance that turns intent into certification.

What social landlords can do next

1. Lock in performance at brief stage. Name Passivhaus (or EnerPHit for retrofit) as the target—not “low-energy in spirit.”

2. Pick procurement that rewards quality. Use routes that prioritise competent teams and verifiable outcomes alongside cost.

3. Design for occupant outcomes. Budget for post-occupancy monitoring and resident support; share findings to build sector confidence.

4. Grow your local bench. Ring-fence time for staff and supply-chain partners to train and bring a certifier in early.

5. Make the grant case. Evidence fuel-poverty, health, maintenance and lifecycle savings when engaging funders.

The bigger picture

Every completed project is a multiplier: it upskills contractors, normalises the details, expands the supply chain and proves that “net-zero ready” is a spec, not a slogan. Northern Ireland’s Passivhaus lift-off isn’t hype—it’s homes on the ground, tools in hand, data coming in, and a clearer path to warmer, cheaper-to-run social housing across the region.
