Scottish housing association cracks the safe on decarbonising social housing 
 

Passive House Plus magazine, August 2023

How do you solve a problem like decarbonising social housing, and do so rapidly, en masse, in a manner that lifts vulnerable people out of fuel poverty while delivering warm, healthy homes? River Clyde Homes may be about to pull off the seemingly impossible.

Rapidly decarbonising our built environment is an urgent task, but it poses a vicious puzzle: how to do it fast, but do it well? And how to pay for it? Deep retrofit is complex, and poorly executed upgrades have a history of causing damp and mould.  

The UK and Ireland both plan to become zero carbon societies by 2050. Both countries will need to upgrade a large majority of their homes — two million dwellings in Ireland, twenty-seven million in the UK— by 2050. This will require an unprecedented scaling up of retrofit, and an unprecedented level of investment.  

The UK government sees heat pumps as one answer to this challenge — it wants to install 600,000 every year from 2028 onwards to deliver low carbon heat to homes, with less emphasis on fabric upgrades.  

But heat pumps require careful design and installation, and if electricity prices are high, they can run up frightful bills in poorly insulated homes. Deep fabric upgrades are better at cutting fuel poverty and making homes comfortable, but they can be complex and expensive.  

One housing association in Scotland has come up with a different answer to this puzzle. River Clyde Homes, which manages 6,000 dwellings in Inverclyde, west of Glasgow, wants to decarbonise its housing stock through a mix of whole-house retrofit, low carbon heat networks, and by generating its own renewable energy.

Priory Hall is not an exception

Published in Village magazine, May 2012 Priory Hall is no exception — a history of poor regulation and enforcement has left many of us living in shoddy homes, argues Lenny Antonelli

The government has launched a public consultation on building control following the high profile evacuation of the Priory Hall development in north Dublin due to fire safety defects.

But the proposed changes are nothing more than a paper exercise that will do little to boost the number of on site building inspections.

The new rules demand the submission of "certificates of compliance" confirming a project meets the legal requirements of the building regulations. Drawings showing how a building complies will also have to be lodged. But it speaks volumes that such basic measures aren't already in place.

Following Priory Hall, environment minister Phil Hogan said the fact Dublin City Council took the case to court "is a clear indication the Building Control Act is robust" (1). But if the act was robust, 240 people wouldn't have moved into a faulty building. And the government wouldn't be fixing the act six months later.

Priory Hall highlighted the lack of on-site building inspection in Ireland. The government requires local authorities to inspect just 12-15% of buildings. In 2010 — the last year for which figures are available — the average local authority inspected just a quarter of buildings. Four local authorities failed to meet their target, and two —Wexford County and Waterford City Councils — inspected no buildings at all.(2)

But the Irish Home Builders Association — a division of the Construction Industry Federation (CIF) — defended Irish builders in the wake of Priory Hall, and said the system of self-certifying buildings had worked well.

"Priory Hall is an exceptional case," director Hubert Fitzpatrick told Construction, the CIF magazine last October. But is it really? (3)

None of the houses examined for a study of 52 homes built between 1997 and 2002 complied fully with building regulations. The study was commissioned by the Sustainable Energy Authority of Ireland but never published. Green building magazine Construct Ireland, which I'm deputy editor of, obtained it last year.

The study examined the homes for compliance with regulations on energy efficiency, ventilation and "heat producing appliances". Just one complied with energy efficiency rules in full, almost half failed to meet the rules for heat producing appliances, and over 40% failed to minimum ventilation standards. (5)

In a 2005 study, the National Disability Authority found housing had a "poor level of compliance" with Part M of the building regulations, which deals with access for people with disability.

These are the only two known studies that have looked at whether Irish housing complies with any parts of building regulations, according to the Department of Environment.

Other stories undermine the idea the Priory Hall is an exception. Up to 20,000 homes may now be infected with pyrite, a mineral that can cause some construction materials to expand and crack if exposed to air and water (7). Socialist TD Joe Higgins described these homes as "exploding in slow motion".

Meanwhile in Balgaddy, West Dublin, up to 400 local authority houses built at the height of the boom are plagued by dampness, mold, cracking, leaks, and electrical and sewage faults. (8)

And earlier this year, it was reported that up to 300 homes and apartments at Balmayne, north Dublin require expensive repairs due to fire safety faults.(9)

Though it's little comfort to the people living in there, these cases are the natural outcome of decades of under-regulation, lack of enforcement and lobbying against better building standards.

Though the first draft was written in 1967, building regulations weren't made law until more than 20 years later.(10)

As far back as 1978, Construction Industry Federation managing director Thomas Reynolds said making any insulation mandatory in new homes would be "entirely unrealistic and bureaucratic". (11)

That same year, the Building Industry Council urged the Department of Environment to scrap its draft building regulations and re-write it "with a greater understanding of the impact such regulations will have on industry." (12)

Then in 1982, the Irish Times reported that Aidan McDonald, a Department of Environment official, told the Stardust disaster tribunal that the building industry had lobbied against a system of building inspection and approval. The department accepted the industy's arguments and decided to move towards self certification, the Times reported. (13)

Building regulations finally came into force in the early nineties, along with the self certification system that gave us Priory Hall.

In 1998, an internal Department of Environment memo acknowledged energy efficiency standards were inadequate and needed updating. "We don't want to signal this to the outside world yet because the next leap in building standard insulation will probably involve making it difficult for 'hollow block' construction, used widely in Dublin, to survive," the memo read. This was revealed in a freedom of information request to Century Homes founder Gerry McCaughey. (14)

But the department didn't update the rules for another four years, during which hundreds of thousands of homes were built.

Then in 2007, the Construction Industry Federation warned that plans to boost minimum energy efficiency standards by 40% would add €15,000 to the price of new homes. The price rise never materialised. (15)

The Irish Homes Builders Association objected to plans the same year by Dun Laoghaire - Rathdown County Council to introduce its own tough energy efficiency rules, arguing the target was unachievable. (16) But a similar standard is now in effect nationwide.

Insulating a house properly is about more than just it keeping warm.  Over 300,000 households in Ireland experience energy poverty (17). Excess winter mortality — the surplus number of people that die in winter —in Ireland was found to be double that of Norway in a 2000 study by UCD researchers Peter Clinch and Jonathan Healy. Poor building standards could be one of the main causes, the authors said (18). Clinch and Healy also found that over half of elderly households in Ireland endured "inadequate" winter temperatures in a separate study that year. (19)

Countries with the highest winter mortality — Portugal, Spain, Ireland and UK —are also those with the poorest building standards, another study  concluded the following year. (20)

The number of excess winter deaths has fallen since, and insulation standards have improved, but Ireland still experiences more excess winter deaths than the most of Europe, according to the Institute of Public Health. (21)

Upgrading and insulating our building stock could form the core of a green economic programme that would reduce fuel poverty, cut carbon emissions and save construction jobs.

But the government has slashed home energy grants in successive budgets, even though SEAI research found every euro spent delivers a net benefit of €5 to society (22). The uptake of grants has plummeted this year.(23)

Yet in some ways Ireland is actually pushing the boundary of cutting edge, low energy construction. We built the first passive house —the leading standard of ultra low energy building —in the English speaking world, and we've become a world leader in this standard. But this is down to the ambition of our best architects, designers and builders, rather than government initiatives.

On paper, our minimum standards for energy efficiency are strong, but there's little enforcement. At Construct Ireland, we frequently encounter buildings that fail to meet energy efficiency standards — either because the builder or architect doesn't understand how to comply, or because they have little fear of inspection.

In 2009, a spokesperson for the Irish Homes Builders Association said the last government's plan that all new homes be zero carbon by 2013 was "extremely costly and difficult to achieve", and said new insulation rules were "overly prescriptive".(24)

Now the Fine Gael - Labour programme for government only commits to "moving towards zero carbon homes in the longer term." The Department of Environment failed to reply to a question I sent its press office asking if the 2013 target had been dropped.

The construction industry pushed against a higher standard, and now the government is delaying it. On paper our regulations might be good, but there's still barely any enforcement. We've been here before.

Half of new homes fail energy efficiency rules

By Lenny Antonelli & Jeff Colley The Sunday Times (Irish edition), 20 May, 2012

More than half of new Irish homes fail to meet energy efficiency and carbon emissions regulations, according to new figures. The number of new homes meeting the rules has also declined dramatically since 2005, according to data released by the Sustainable Energy Authority of Ireland.

The figures show 50% of homes fail to meet energy performance rules, 40% fail to meet carbon emission standards, and 39% don't generate enough renewable energy to meet regulations.

The data, which contains a record of the energy performance of every new home given a building energy rating (BER) assessment, was obtained by the green building magazine Construct Ireland.

Of the 3,595 BER assessments carried out on houses built to the 2008 version of Part L of the building regulations, which deals with insulation and energy, 1,946 — or 54% — fail at least one of the three main standards.

This marked a dramatic increase from the 21% of homes built to the 2005 regulations that failed to meet its main requirements. Part L was updated again last far, but few homes have been built to this new version.

Environment minister Phil Hogan recently published a new draft Building Control Act following the high profile evacuation of the Priory Hall development in north Dublin due to fire safety defects. The new rules require the submission of "certificates of compliance" for the design and construction of buildings.

However in a lengthy submission former president of the Royal Institute of the Architects of Ireland Eoin O'Cofaigh heavily criticised the proposals. He said the regulations would "criminalise" architects for the failure of local authorities to inspect buildings, and for the failure of other contractors on site. Local authorities currently have a target to inspect just 12-15% of new buildings.

Mr O'Cofaigh, a former member for the Building Regulations Advisory Body, said the proposals were the "21st century equivalent of hanging children for stealing sheep."

Last year Construct Ireland  revealed that an unpublished survey of Irish housing built between 1997 and 2002 commissioned by the SEAI found that none of the houses examined complied fully with energy efficiency regulations. Over 90% of of homes with oil boilers failed to comply with rules on reducing the risk of fire spread and pollution from oil tanks, while over 40% failed to meet ventilation standards.

Infra red photography of housing conducted as part of the survey found that 19 out of 20 houses had gaps in insulation, in contravention of the regulations, that were not revealed by basic visual inspections. This suggest the number of homes failing to meet insulation standards today could be higher than the latest SEAI data indicates, as BER assessors typically assume on-paper specifications are correct if they can't access insulation.

SEAI is planning to release a public research tool to enable users to study the BER data it has collected. The next issue of Construct Ireland magazine will contain further analysis of the latest figures. The Department of Environment did not respond to a request for comment from The Sunday Times in time for print.
