RIBA calls for more post occupancy evaluation

RIBA has published a report urging the government, local authorities and the wider construction sector to adopt post-occupancy evaluation as standard practice to ensure all new buildings meet intended energy efficiency ratings and provide optimum value for money.

Experts call for CO2 sensors as tool in Covid fight

CO2 levels in rooms and other enclosed spaces should be used as a proxy for Covid transmission risk, a number of leading experts have said, as the evidence increasingly points towards airborne transmission being a major factor in the spread of the virus.

Building sector must show bold climate leadership

In late 2018, the IPCC issued a stark warning. It highlighted that limiting global warming to 1.5 C is crucial to avoiding the most catastrophic impacts of climate change. It also clearly established that achieving the goals of the Paris climate agreement will require action at an unprecedented pace and scale. To maximise the chances of limiting global warming to 1.5 C, all sectors of the economy must achieve significant emissions reductions, and the building sector must fully decarbonise by 2050.

Hell's kitchen - Why cooking can destroy indoor air quality

When it comes to air pollution, we tend to worry most about things like traffic fumes and solid fuel burning — or when it comes to indoor air, condensation, damp and mould. But one of the biggest threats in the air we breathe comes from something we are exposed to almost every day, but rarely think about: cooking. John Hearne reports on the evidence for how cooking affects indoor air quality, and what we can do about it.

Dead air - airborne covid 19 and poorly ventilated buildings

In the early stages of the Covid-19 crisis, there was little official recognition that airborne transmission was a risk. Has that view changed, and what role will building ventilation play when winter approaches?

Coasting home - Beautifully designed Hampshire home breezes past passive standard

‘Architecture is the blissful moment when the site and brief come together,’ says architect Ruth Butler of the challenge she and her engineer husband faced in designing their family home, on a difficult urban site by the Hampshire coast. But it was a challenge they met and exceeded, because even though they hadn’t even planned to build a passive house, they soon realised the design was on course to meet the onerous energy standard anyway.

Double standards - Mayo home takes passive approach to NZEB

Sited on the side of a hill in the west of Ireland, a new home that meets the NZEB and passive house standards boasts a locally-made and super-insulated timber-frame, and is designed to fold cleverly into the rural landscape.

Net result Bristol passive house turns energy bills into net profits

A ground-breaking new passive house in Bristol makes superb use of an urban plot to create a bright and spacious home built from ecological materials that — thanks to its huge solar roof and Tesla battery pack — produces more energy than it uses, making it one of the first UK projects to meet the passive house ‘plus’ standard, while also blitzing the RIBA 2030 Climate Challenge’s targets for operational energy.

Victoria Falls - 19th century home drops energy demand by 94%

This ambitious renovation and extension of a single-storey Dublin redbrick, bringing it up to an A1 rating while far exceeding the new build NZEB standard, provides a beautifully-detailed blueprint for delivering warmth, comfort, and healthy indoor air — as well as extra space and living density — in historic city centre properties.

Why shading is a major issue in our hospitals

Daylighting, overheating, glare and lack of natural, insect-free ventilation remain significant issues in UK hospitals and may be hampering the ability of patients to recover, and hospital staff to properly care for them, according to UK solar shading manufacturer Smartlouvre.

Circular economy plans come into focus

The European Commission has adopted the EU’s new circular economy action plan, a major part of the European Green deal. The action plan aims to make the EU economy produce more durable, longerlasting, repairable consumer products, and maximise the use of recycled material.

New report questions long-held MVHR assumptions

A new report by the Passivhaus Trust has questioned the common assumption that mechanical ventilation with heat recovery (MVHR) is inappropriate in dwellings with air permeability worse than 3 m3/m2/hour.

Getting to net zero carbon

The UK government has committed to a legally binding target of being “net zero carbon” by 2050. Peter Rickaby ponders the steps needed to get there, and what the goal means for our homes, offices and other buildings.

Environmental activism - tracing the roots of today's climate activism

While the green wave visible at ballot boxes and street marches in 2019 reflects an apparent escalation in public consciousness on the need for urgent, decisive environmental action, the roots of today’s environmental consciousness stretch back over half a century, explains Dr Marc Ó Riain.

Office romance - Passive house supplier walks the walk with new office & factory

When Welsh sustainable building specialists PYC decided to start making their own timber frames, they got down to work designing and building their own factory. Once that was finished, it was time to test their system on their first order: to build their own passive house certified offices right next door – and to be bold enough to decide not to install central heating.

Doctor's orders - The complex relationship between energy retrofits and human health

There is no shortage of anecdotal evidence that home energy retrofits, done well, can improve the health of those who receive them — and equally there are horror stories about shoddy upgrades causing damp, mould and illness. But what does the evidence say about how energy upgrades effect occupant health, and what lessons can be learned for the future of how we renovate our homes? Kate de Selincourt reports.

Flat pack hijack
