No understanding of efficiency. A 20% reduction in energy consumption is not a increase in efficiency.

Dude just stick to tug boats. You are so far out of your depth I don't even know where to start.

another possible feature of climate change:

"Tens of thousands of people in communities across the country have been forced to evacuate as firefighters battle to contain the blazes that have scorched more than 3.8 million hectares (9.4 million acres) so far.

But the emergence of smoke-filled, discoloured skies in parts of Canada that typically aren’t affected by wildfires has spurred widespread public concern and calls for authorities to better prepare for a problem that experts say is only going to get worse."

That one is a feature of arson, dik.

SwinnyGG, reducing a building's energy consumption may be accomplished by exporting services (I used laundry as an example earlier). This does not equal an increase in efficiency.

 

[SwinnyGG]

You're making it clear you have zero understanding of how building energy efficiency is engineered, tested, or certified.

Just stop. You have no idea what you're talking about.

 

[dik]

Tug... reassigning it is not reducing it... this works only if more efficient to reassign, else energy input may be greater.

[TugboatEng]

SwinnyGG, there are hundreds of ways to describe a building's efficiency. I'm poking fun at the article because they use dimensionless numbers (percentage) to describe undefined terms (efficiency). For example, I could reduce the size of individual apartments to increase the number of residents per square foot. That's an example of higher building efficiency but I doubt that is what the writers were thinking.

 

[dik]

From the BBC, it may be starting...

"US scientists confirmed that El Niño had started. Experts say it will likely make 2024 the world's hottest year.

They fear it will help push the world past a key 1.5C warming milestone.

It will also affect world weather, potentially bringing drought to Australia, more rain to the southern US, and weakening India's monsoon.

The event will likely last until next spring, after which its impacts will recede."

Again, you're demonstrating clear lack of knowledge of the field.

There are very well defined industry standards that describe exactly how building envelopes and MEP systems are evaluated with regard to energy efficiency. There are a couple of different systems approaches with their own methods - but they are all well developed. There is no ambiguity.

 

[JoshPlumSE]

There are some very well defined standards that are used for energy efficiency of buildings. But, my impression has always been that these are like QB ratings in the NFL. They are specific rules about how they are calculated. However, they don't tell the whole story. You can manipulate the building to improve the rating in ways that do not improve the REALITY of the performance.

Didn't Tim Teabow have a terrible QB rating and a wonderful QBR (or vice versa). Whereas when anyone who knows football would watch a game and see that he was not an effective quarterback. He did some things well (rushing, avoiding turnovers). But, the proof is in the pudding.... no one in the NFL wanted him to run their offense because he just couldn't do it. Whether he wasn't very smart (he wasn't) or he couldn't throw the ball quickly or accurately (he couldn't). But, all the NFL cares about is winning games. He seemed to do that reasonably well. But, the reality is that TEBOW wasn't the reason why the Broncos won games. They had a historically good defense. He was, at best, a game manager. Which we saw when they signed a real QB (Peyton Manning) and what that did for the team.

I feel like all these LEED ratings are similar. They mostly measure how good of a job you do manipulating the rules of the LEED rating system. It's a good system, in that owners who want better energy efficiency can get something that has value and which increases the value of the building. But, they genuinely do not tell the whole story.

 

[TugboatEng]

There are very well defined industry standards that describe exactly how building envelopes and MEP systems are evaluated with regard to energy efficiency.

I am very aware of this. The problem is that we don't know exactly what industry standard is being used. It's NEVER stated or even implied.

Dik,
I thought these threads were about man made climate change. El Niño and La Niña cycles predate the industrial revolution.

 

[dik]

Did you think for a minute that man made climate change may have a serious impact on ENSO? We'll may find out later this year, just how much.

"El Niño is developing rapidly, with an official watch currently in effect, issued by NOAA. A moderate to strong El Niño event is expected to occur, with global weather impacts in the second half of the year and over the Winter season of 2023/2024. Based on the latest global anomaly data, this El Niño might be something we have never seen before in such an environment.

Ocean anomalies have a known impact on the atmosphere and our weather on smaller and larger scales, especially during the Winter season, when the pressure systems are strongest."

[enginesrus]

dik, you said man made correct? Right on it is man engineered climate change. Just look how it is being used, the new regs and all that, the changing of our lives.

 

[dik]

Hold on to your hat, there could be a lot more changes coming.

Hold onto your wallet; there's always changes when it comes to the weather and the climate. The politicians and opportunists will use every one as an excuse to pick your pockets.

That too...

[CWB1]

The part about residential energy efficiency which always amazed me is that regulators set such a low standard in the southern states where HVAC drives much higher energy demand than in the north.

 

[dik]

It's still a power requirement. My undergrad study was in hydraulics and water resources. Manitoba was in the enviable position that our peak hydro loads were in the winter and we exported hydro to the states in the summer, to service AC units. This has changed, we now have a high demand in the summer for AC. Additional improvements to the building envelope help reduce the building's energy consumption... it helps both north and south. From our perspective, it appears that many of the southern states are caught in a bit of a 'time warp'. This will change, I hope.

As an aside... a couple of days back, in western Manitoba, the news reports that we had hailstones the size of softballs... I've seen them the size of ping pong balls, but nothing that huge. This could be a feature of new climate conditions. I remember as a kid, reaching my hand out the window trying to catch a hailstone to see what they were like... only ever did that once... We'll have to see what happens.

don't worry ... "they" will take away our AC ... as a first world luxury that we can't afford any more

It may reach a point, where most people will not be able to afford them...
