'The past is an underused tool': An Elizabethan mansion's secrets for staying warm

6 min read Original article ↗

Elizabeth (Bess), Countess of Shrewsbury, was the woman who had deep enough pockets to build it. She was mid-way through extending the massive, rambling Hardwick "old" Hall, but for some reason or another, stopped midway through and began afresh. The experts I spoke to say we don't know why she did that, but theories range from coming into money when her husband died and feeling the need to have a house in keeping with her elevated status, to using what she'd learnt in previous builds to design a house warm and cosy for a lady approaching her seventies and living through the Little Ice Age.

"The late 16th Century is really one of the coldest stretches of the Little Ice Age, and it's bitterly cold in England," says Dagomar Degroot, professor of environmental history at Georgetown University in Washington, DC, and author of The Frigid Golden Age.

Global average temperatures during the Little Ice Age dipped "at most" by 0.5C (less than 0.9F), with impacts mostly documented in the northern hemisphere. That figure is an average over about five centuries, so temperatures would have swung more dramatically year to year and region to region.

Turning to the Sun

A key difference between the old hall and the new hall is their orientation in relation to the Sun. The old hall is just off east-west. The new hall has been rotated by about 90 degrees, which means it can soak up much more sunshine and, therefore, heat.

"The incredible thing about Hardwick [new Hall] is… when you set it on the compass, it's almost exactly north-south," says Ranald Lawrence, a lecturer in architecture at the University of Liverpool in the UK. He's also published papers on Hardwick's design and thermal comfort. "And," he adds, "the whole internal planning of the [new] house is then based around that geometry."

Bess moved around the rooms, following the Sun's path. Her mornings were spent walking the 63m (200ft) east-facing Long Gallery, where the bright morning light hits. The afternoon and evening Sun illuminates the south-western flank of the building, where Bess' bed chambers were. And the darkest, coldest corner of the house in the north-west was where the kitchens were placed, which would have been handy in keeping food cool and fresh.

I experience this first hand as I walk around – the kitchens are much colder. Elena Williams, the senior house and collections manager at The National Trust, a UK charity which preserves historic sites, notices too. "It's a well-designed building that is also designed around comfort and that uses the natural environment to do that," she says.

Windows, walls and fireplaces

It's not just the orientation that helps keep the house warm. As Williams shows me around, she points out that some of the windows on the north of the building are actually "blind" or fake. She explains that on the outside, there is a window, but on the inside, it's lined with lead and blocked up. Unlike south-facing windows, north-facing windows bring little thermal benefit, even in summer, Lawrence says.

Pretty much all the fireplaces I see are also built on the central spine of the building, meaning not much heat would be lost to the windows or exterior wall. It's not until we take a door through this spine that I realise that the girth of it is staggering – 1.37m (4.5ft) thick. This is yet another trick to keep its inhabitants warm.

"The past is an underused tool," Degroot says. "I think by trying to identify the complex and diverse ways in which people responded to history's climate changes, we can come up with new tools for understanding how we might respond in the future and for identifying responses that are constructive versus destructive." 

Brutalist architects Peter and Alison Smithson knew of and even admired Hardwick Hall. Some academics claim that it likely inspired their own designs, like the Solar Pavillion, in south-west England, which is only has glass on its east, west and south-facing walls. Sun-soaking designs aren't just the preserve of the rich, though. One of London's most striking council estates is on Alexandria Road in Camden, in the north of the city, and Lawrence says it too features south facing terraces with lots of concrete to store the Sun's heat.

But on the whole, he tells me, we generally don't use these Elizabethan building secrets. Instead, we use air conditioning and heating in an attempt to override building designs that are poorly suited to their climate.

"Our assumption that the solution to all of our problems is technological," Lawrence says. Glass box skyscrapers, now common in both cold and hot climates, are a good example of this. In winter, heat escapes through the glass, and require a lot of heating. Conversely in summer, the glass traps the heat – like a greenhouse – and require massive amounts of energy for cooling.

But without taking apart our existing housing and building it again from scratch, there are also micro-adjustments we can make. 

More like this:

I get a compass out at my house – for the first time – and begin to think about how I could follow the Sun's path throughout the day. Since it's winter, and cold, I move my desk to a south-eastern window. It brightens the mornings and if I wear another layer, I find I can lower the thermostat by 2C (3.6F). Longer term, I've been thinking about planting a tree just outside. In a couple of decades, it would shade my house from scorching heatwaves that are predicted to be much more common because of climate change.

These are modest changes, imperceptible to most, and they won't enable us to forgo active heating and cooling entirely. But they do echo a way of thinking which, today, is oft ignored. Hardwick Hall was designed with Sun, season and temperature in mind. It paid attention to the world outside its walls. As the climate becomes more volatile, architecture that works with its environment feels more urgent than ever.
