Northern Ireland’s unique context, particularly in energy, will require further innovation and a strategic joined up approach to improve energy performance of its buildings

While decarbonisation of the heat network remains one the toughest challenges, an energy efficient building fabric is needed to be both effective in cost savings and emissions reductions. Patrice Cairns discusses the situation in Northern Ireland in an article on The Irish News website.

 

Overhaul of energy performance in existing housing stock essential

Under the period of lockdown, where for many their home has become not only their shelter but a place of work, of home schooling, of social space and respite, it can be assumed that there is a greater appreciation of the intrinsic link between wellbeing and improved indoor health. But if we spend more time at home, we will typically use more energy.

The built environment sector contributes significantly to national energy use and carbon emissions, yet progress in the decarbonisation of buildings has been limited and the challenge going forward even greater. As new housing accounts for only one to two per cent of total UK building stock each year, addressing the energy efficiency of existing housing stock is a crucial milestone on the path to achieving net zero ambitions.

Given that approximately 15 per cent of the UK’s total emissions come from heating homes alone, an overhaul of the energy performance of existing housing stock is required.

Northern Ireland’s unique context, particularly in energy, will require further innovation and a strategic joined up approach. While decarbonisation of the heat network remains one the toughest challenges, an energy efficient building fabric is needed to be both effective in cost savings and emissions reductions.

This requires a significant scaling up of retrofitting homes, which not only provides an opportunity to achieve both operational carbon and significant embodied carbon savings, through re-use rather than re-build, but can improve indoor conditions and create skilled jobs. The task is formidable, and immediate action is needed to close the widening gap.

In Northern Ireland, the absence of climate change legislation – though promised in New Decade, New Approach – the lack of clear regulatory drivers such as ambitious building regulations which account for embodied carbon and Minimum Energy Efficiency Standards (MEES), and the lack of financial incentives and support to encourage all households to retrofit, creates concern that existing polices will not be enough to deliver the level of carbon reduction required.

Rics has recently published a new paper calling on UK government to make a step-change in policies for decarbonising existing UK housing. ‘Retrofitting to decarbonise UK existing housing stock’ provides a blueprint for government to take forward as part of their resilient recovery from Covid-19.

The paper highlights how government incentives can promote a positive shift, by encouraging and supporting more people to consider making their homes energy efficient. The suite of policy recommendations is encapsulated in a package of regulatory measures, industry standards and property data, fiscal levers and market insight.

UK government endorsing Rics’ call to reduce the VAT for home repairs, maintenance and improvement work would be a swift step in the right direction. A uniform reduction to five per cent across the regime could provide a much-needed boost in the adoption of retrofitting measures being taken in tandem with home improvement upgrades.

Although the incentive will carry an initial cost, it will be at least in part offset by the benefits associated with job creation, which will be much needed in the wake of the likely rise in unemployment as the furlough scheme begins to unwind.

While the energy efficiency policy route remains uncertain both at a Northern Ireland and UK level, the Stormont Executive must use this opportunity to review their existing policies, working with the expertise of industry, and implement a holistic approach to retrofitting. The Executive committing to a more sustainable stock of housing provides an opportunity both to kickstart business activity and focus on the green agenda.

A scaled up retrofit programme of existing housing stock would be an integral stimulus to a green, and climate-resilient recovery from the impacts of the Covid-19 pandemic.

Designating the energy efficiency of Northern Ireland’s building stock as a regional infrastructure priority, with appropriate long-term investment to fill the gap, would be a driver in the delivery of the required scale of retrofit.

Upskilling and supporting the pipeline of green skills, within the built environment and including the prop-tech sector, to deliver improvements in energy efficiency would provide further socio-economic stimulus. The time to act is now.
