It's actually the design of our homes and apartments that has the biggest impact on energy efficiency, something that I wish more people knew about building sustainably is that it's not as expensive or challenging as they may think there are ways to make changes that can make your home much more environmentally conscious without it being this like astronomical price tag architects like Sienna shaw are building with these techniques to bring a household energy demand down by 80% or more.

實際上，我們的住宅和公寓的設計對能源效率的影響最大，我希望更多的人瞭解可持續建築，它並不像他們想象的那樣昂貴或具有挑戰性，有一些方法可以使你的家更有環保意識，而不是像天文數字一樣的價格標籤，像Sienna shaw這樣的建築師正在用這些技術建造，使家庭能源需求下降80%或更多。

The house that's standing behind me is a project that my partner brian and I did gosh, it was like one of those dreams right?

站在我身後的房子是我和我的夥伴布萊恩做的一個項目，天哪，這就像那些夢想之一，對嗎？

Like well we don't have the money to buy a property and build our own house right now, but we can buy trailer and we can build our dreams basically.

比如說，我們現在沒有錢買房，沒有錢建自己的房子，但是我們可以買拖車，我們基本上可以建立自己的夢想。

But at a much smaller footprint right before we get into how Sienna builds environmentally friendly homes, let's first get into how temperature is actually stored in a house and how it can be lost if you had a cooler that you were trying to keep everything inside cold and then but you had a bunch of holes and you're out in the middle of the desert, like the ice is gonna melt inside, right?

但是，在我們進入Sienna如何建造環保住宅之前，讓我們先來了解一下溫度實際上是如何儲存在房子裡的，以及如果你有一個冷卻器，你試圖讓裡面的東西保持低溫，然後但你有一堆洞，你在沙漠中間，就像冰會在裡面融化，對嗎？

And it's the same sort of idea.

這也是同樣的想法。

But if it's completely sealed up and you keep it closed, it's able to maintain that temperature for much longer.

但是，如果它完全密封起來，你保持它的封閉，它就能更長時間地保持這個溫度。

So when the heaters blasting, if the house is full of holes, all that hot air is just escaping outside.

是以，當暖氣片爆炸時，如果房子裡到處都是洞，所有這些熱空氣就會逃到外面去。

This is obviously a waste of energy and results in those harmful carbon emissions.

這顯然是對能源的浪費，並導致那些有害的碳排放。

Every building has what's called a building envelope.

每個建築物都有所謂的建築圍護結構。

And this is basically that sealed cooler.

而這基本上就是那個密封冷卻器。

You ideally want a building envelope that doesn't leak.

你最好想要一個不漏水的建築圍護結構。

Like at all, I think about it.

像在所有，我想了想。

Houses used to be built with temperature as the top priority before we had energy guzzling mechanical systems to change the temperature to whatever we wanted.

在我們擁有耗費能源的機械系統將溫度改變為我們想要的任何溫度之前，房屋的建造曾以溫度為首要考慮。

Builders had to use natural forces and clever engineering.

建設者不得不利用自然力量和巧妙的工程。

So houses were basically thermal batteries, storing heat in case it's needed later.

所以房子基本上是熱電池，儲存熱量以備以後需要。

And don't get me wrong, it's great that we now have the technology to heat and cool rooms at the touch of a button because I'm cold like all the time.

不要誤會我的意思，我們現在有了一鍵加熱和冷卻房間的技術，這很好，因為我一直都很冷。

But air conditioners and heaters take so much energy to work.

但是，空調和加熱器需要如此多的能量來工作。

And in fact, more than half of the average household energy consumption is used just for heating and air conditioning.

而事實上，平均家庭能源消耗的一半以上只是用於供暖和空調。

But what if we built homes?

但如果我們建造房屋呢？

So they didn't need tons of power to be constantly heated and cooled?

所以他們不需要大量的電力來不斷地加熱和冷卻？

If we didn't have to rely on these machines, we aren't putting those damaging carbon emissions out into the atmosphere, which is good, like really great.

如果我們不必依賴這些機器，我們就不會把這些破壞性的碳排放到大氣中，這很好，就像真的很好。

So the technology has been getting more energy efficient over time.

是以，隨著時間的推移，該技術一直在變得更加節能。

Think about those light bulbs and double paned windows and better insulation.

想想那些燈泡和雙層玻璃窗以及更好的絕緣材料。

We've already improved so much but homes are a lot bigger than they used to be.

我們已經改善了很多，但房屋比過去大了很多。

And so when we expand the square footage, it's just wiping out the gains that we've made an easy way to tell how sealed and insulated your home or apartment or adventure van or whatever you live in is just by turning off your heat on a cold day and tracking how long it takes for it to cool.

是以，當我們擴大面積時，只是抹去了我們的收益，我們已經做了一個簡單的方法來告訴你的家或公寓或冒險車或你住的任何東西的密封和絕緣程度，只是在寒冷的日子裡關閉你的熱量並跟蹤它需要多長時間來冷卻。

When air leaks out of the house, it goes through the little holes it goes through cracks and those things exist all over the house.

當空氣從房子裡漏出來時，它通過小孔，通過裂縫，這些東西在房子裡到處存在。

A lot of houses.

很多房子。

This is obviously a waste of energy and results in those harmful carbon emissions.

這顯然是對能源的浪費，並導致那些有害的碳排放。

The older houses, half of the energy used in them or more can go to heating, cooling newer houses.

老房子，其中使用的一半或更多的能源可以用於加熱，冷卻較新的房子。

It might be a quarter or less, especially if you're doing something like a passive house, which is a program that requires really high levels of insulation and air tightness.

它可能是四分之一或更少，特別是如果你正在做像被動房這樣的事情，這是一個要求真正高水平的絕緣和氣密性的項目。

And if you were in what's called a passive house, it would stay warm for a super long time without any mechanical help.

如果你是在所謂的被動式房屋中，它將在沒有任何機械幫助的情況下保持超長時間的溫暖。

So this mighty house.

所以這個強大的房子。

We tested out building to passive house standards.

我們按照被動房標準測試了建築。

I think at a small scale this house is a really good example of what an attainable, energy efficient house can be.

我認為在小範圍內，這個房子是一個非常好的例子，說明一個可實現的、節能的房子可以是什麼。

It's not super high tech.

這不是超級高技術。

there's not like a lot of complicated materials or techniques or methods that went into designing it or building it.

沒有像很多複雜的材料或技術或方法，去設計或建造它。

So everything about this house was carefully designed to optimize energy control.

是以，這個房子的一切都經過精心設計，以優化能源控制。

The installation is a particularly great example of this.

該裝置是這方面的一個特別好的例子。

This house has somewhat of a standard internal core, right?

這個房子有點像標準的內部核心，對嗎？

Like there's um standard wood, uh two by four wood studs and then there's sheathing layer of plywood and then there's a building wrap on it which stop the wind from infiltrating through the different layers and that's all taped so every seam is taped and sealed to prevent air from going through and then the whole building is wrapped with this mineral.

比如有標準的木頭，呃，2乘4的木牆骨，然後有膠合板的覆蓋層，然後有建築包層，阻止風從不同的層中滲入，這一切都被貼上了膠帶，所以每個接縫都被貼上了膠帶和密封，以防止空氣通過，然後整個建築被這種礦物包裹著。

And then the next step is this rain screen which is reclaimed redwood fence boards that we milled down.

然後下一步是這個雨幕，它是回收的紅木柵欄板，我們把它銑下來。

And then this allows the whole assembly to breathe using all of those carefully selected layers prevents the heat from escaping.

然後，這使得整個組件能夠呼吸，使用所有這些精心挑選的層，防止熱量外洩。

Like we were talking about earlier, it was like a great way for us to test all those ideas and to do it with using the highest quality materials that were available at the time.

就像我們之前說的，這對我們來說是一個測試所有這些想法的好方法，並使用當時可用的最高品質的材料來做。

So if every crack in the house is sealed shut, I want to get stuffy.

是以，如果房子裡的每一個裂縫都被封死了，我想就會變得很悶。

What about like fresh air.

像新鮮空氣一樣呢。

Well Sienna thought of that too.

嗯，西恩娜也想到了這一點。

This is half of the RV system that I'm looking at up here basically what it's doing is it's pulling fresh air from the outside into the building and then the other half which is located up in the loft is exhausting and these two talk to each other and they alternate so that the air is changed over in the space um continually.

這是我所看到的房車系統的一半，基本上它所做的是把新鮮空氣從外面拉到大樓裡，然後另一半位於閣樓上的空氣被排出，這兩個系統互相交談，它們交替進行，這樣空氣就在空間裡不斷地被更換。

So basically that creates a situation where if we close up all the windows and we would still have fresh air in here and these solutions stealing a house insulating it, recovering energy.

是以，基本上這創造了一種情況，如果我們關閉所有的窗戶，我們仍然會有新鮮的空氣在這裡，這些解決方案竊取了一個房子的絕緣，恢復了能源。

They work for bigger buildings too, so as far as like taking these details and scaling them up for bigger apartment complexes or multi family dwellings or that sort of thing, it's possible and really exciting to see these principles being implemented at much larger scales because larger buildings, larger impacts.

它們也適用於更大的建築，所以就像把這些細節放大到更大的公寓樓或多戶住宅或諸如此類的事情而言，看到這些原則在更大的規模上被實施是可能的，而且真的很令人興奮，因為更大的建築，更大的影響。

Yeah, it's all exciting.

是的，這一切都很令人興奮。

I don't know about you but after all this, I have some new ideas that I can implement in my house right now and for my future dream home, my name is Nita of Notes by Nivea and this is seekers, impact of everything.

我不知道你的情況，但經過這一切，我有一些新的想法，我現在可以在我的家裡和我未來的夢想之家實施，我的名字是Notes by Nivea的尼塔，這是尋求者，影響一切。

We're going to be talking about how all kinds of everyday things are becoming more sustainable and giving you the details into how it all works.

我們將討論各種日常事物如何變得更加可持續，並向你詳細介紹這一切是如何進行的。

So keep an eye out for more episodes.

是以，請關注更多的劇集。
