All right, folks.

Hey, my name is Phil Zito, and I'm the founder and CEO of Building Automation Monthly.

We are a provider of online training for building automation professionals.

So right now, at the time I'm recording this, a lot of schools are starting to close and businesses are starting to close down because of the coronavirus.

A lot of people are stuck inside.

And I thought to myself, man, you know, we give out our podcast every week.

Why not just do a weekly, or daily rather, unscripted training series on building automation.

And so that, my friends, is actually what you are watching right now.

You're watching part one of this multi-part series.

And basically what we're going to do is we are going to forever long this little virus thing goes on.

Every weekday, I'm going to be recording.

And right now you can see I've got 21 days.

So I'm hopeful that this is not going to last that long.

But I'll be recording a topic for you.

And my hope is that you're going to come out of this,

you know, staying at home thing with a lot more knowledge of building automation and that people in the future, because I'll put this on YouTube,

I'll put this on our website, people in the future can use this as well just to help them become more aware of what building automation is,

how it works, and just in general help out the community.

So today's topic is going to be on an introduction to building automation.

So in order to get started on this entire journey,

I mean, from inputs and outputs to controls theory to IT to programming to HVAC, et cetera, et cetera, we really have to know where we're starting.

And we're starting at building automation systems, kind of what those are.

Now, I'm going to give you a couple of resources.

I'll put these in a link below the video that you can go to after the fact.

And I encourage you to use these resources, one of which is this Honeywell Gray Manual,

which I personally used when I was first getting into this industry.

Just a little background on me real quickly in case you don't know who I am.

I used to lead the integration program at Johnson Controls, coming up with all sorts of complex integrations.

I've been in sales.

I've been in operations.

I've led ops teams.

I've written a book on building automation, created like 13 courses now, and we've got the fastest growing BAS training business with, at the time of this recording,

5,500 students who are enrolled in our courses.

All right, so all that being said, I know a thing or two about building automation.

And what I find is when folks start to talk about building automation, the first thing they get mixed up is building automation versus control systems.

So this is a building automation controller.

Like this one's an integral actuator controller.

And what it has, this would most likely go on a VAV box.

And then this is just most likely a basically like a building controller for an air handler or a small central plant.

And what you can see, and let me kind of get some larger icons here.

But what you can see as you start to look at these controllers is that they have inputs, they have outputs, they have field trunks.

And if none of this makes sense to you, don't worry, because this is just no review right now.

We're going to be going much deeper as this course progresses.

But these controllers, they have inputs, they have outputs, they have field trunks to communicate to supervisory devices.

Right now, by the way, I just want you to get familiar with these terms.

You're hearing me say inputs, outputs, field trunks, supervisory devices.

Don't worry about what they mean.

Just be comfortable with the terminology.

So all of these come together, and the entire collection of all of this, supervisory devices, inputs, outputs, field trunks,

field controllers, is known as a building automation system.

Its purpose is to automate your building.

So, you know, it had network engines or supervisory devices connected to field trunks, connected to controllers, which process inputs and outputs to make things happen in a building.

But it wasn't always this way.

When this all started, so it all started with the thermostat, right?

We had thermostats that basically would allow us to turn on radiators

or to open louvers or dampers in order to allow fresh air into a building.

And that was kind of the limit of things until pneumatics came about.

And the reason I have this gray manual on my screen is because as you hear me talk, I'm going to recommend

that you start to work through kind of this controls fundamentals where it's going to talk about different types of systems,

pneumatics versus DDC versus analog, et cetera, et cetera.

Well, what happened basically was we started off with just basic thermostats thermostats, like not what you have in your house today not electromechanical thermostats

that basically sense the temperature change

and then energize a relay no we had just basic contact uh as metal elements expanded you would go

and make contacts happen things like that and not even

that complex in the very beginning then we moved to pneumatics

which is basically pressurized air

and pressurized air would flow around it through a series of accumulators and regulators and solenoid valves and things like that, you would make things happen inside the building.

You would have like your air handling units and your valves

and your dampers and your fans and your inlet vanes and all sorts of stuff.

And it was all controlled by pneumatics.

Well, around 1970, 1980, we started to get into microprocessor controls.

So basically, you know, computers were the big thing in the 1970s.

Everyone, 1980s, everyone's like, oh my gosh, get a desktop, right?

I mean, people could actually afford one now.

Well, as all that started to happen, we actually started to have computer chips in our controllers, and this was known as direct digital control.

And direct digital control, more so towards the late 80s, what that allowed us to do is actually program our controllers

so we could go into software that didn't really look like this.

I mean, this is modern GFX, disc tech software, but looks something like this, right?

And so this software would then allow us to go and program.

And in the beginning, it was actually application-specific controllers where you would actually go into like a graphical user interface

or use a set of DIP switches and you would pick a pre-configured program.

But then we got to what's called free programmable controllers.

And so inside these controllers, we could actually freely program them.

Now, that's all well and good that you could program these DDC systems.

That's wonderful and great.

The problem was we had no way of really taking this data out of the controller

and putting it on a screen like you're seeing right now so that someone could actually do something with it.

And that's where these supervisory devices came in, right?

So you may have heard network engines.

You may have heard of Java application control engines.

You may have heard of JASIS, WebSoup, whatever you've heard of.

The main purpose of supervisory devices originally was to take data from these field controllers and put it into a thick client,

so just a stationary desktop that could display data from the field controllers and allow the building operator to interface.

And this was a big freaking deal.

Like, this didn't exist before then.

Before then, you actually had to go and read gauges.

You had to go and change things in your pneumatic system.

You didn't have these capabilities.

But now with DDC and with supervisory devices and the ability to put these into thick clients,

100

which basically a thick client is software that is in the actual PC, in the desktop.

101

And it's not accessed via a web browser like ThinClient.

102

Like nowadays, we use web browsers to access our building automation system, and that is called a thin client or a web app, right?

103

Well, we didn't have that.

104

And so what happened is you had these supervisory devices, and they would then communicate to a user interface.

105

Fast forward, you know, another 10, 20 years.

106

Now we're starting to have web-based building automation systems, cloud-based building automation systems.

107

We're starting to decouple ourselves from the supervisory device

108

and starting to make it to where we only need to use field controllers and web front ends.

109

And the field controllers are actually smart enough to have a web interface into them.

110

Now, I realize this is 101, this is BAS 101 for you right now.

111

A lot of what I just said probably doesn't make sense.

112

There's a lot of background to it.

113

Like I said, don't worry.

114

We're going to be going through BAS inputs and outputs.

115

We're going to be going through control modes.

116

We're going to be going through devices.

117

We're going to take a look at our little control wall that's behind me here.

118

And we're going to have a lot of fun with this.

119

I'm going to try to keep each one of these videos at about 10 minutes.

120

That way you can kind of catch them in between a break.

121

My goal is that by the end of this whole series, it'll be a couple hours worth of content that you could go through.

122

And it'll be a really solid primer on BAS.

123

What I want you to do, so depending on where you're watching this, whether you're watching this on Facebook or on YouTube, or whether you're watching this on our website,

124

there's going to be a place where you can ask questions in the comment section.

125

I encourage you to do that.

126

If there's something that you just feel was missed, please reach out.

127

Like I said, tomorrow is going to be much more graphical

128

because we're going to be having the camera and we're going to be looking at actual inputs and outputs.

129

But today, just a very basic, and I want you to definitely use these links right here.

130

They're going to be below the video in the comments or in the description, depending on where you're watching it.

131

Be sure to check out the rest of our content at buildingautomationmonthly.com.

132

I encourage you to do that.

133

We have 200-plus podcast episodes.

134

We have a bunch of information that would be really valuable for you.

135

And I look forward to seeing you in tomorrow's video.

136

Thanks a ton, and take care.

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
