Why is it that our Engineers don't design a central Air conditioning systems in our high rise buildings. Is it that they are not cost effective or difficult to maintain?

It's because of corruption. Have you heard about buildings collapsing in Nigeria? It happens often. They build anything as cheap as possible to have enough money to loot.

Nigerians loot money in everything, including things that would benefit them!

Don't live in any building built after 2000, unless you built it yourself and sure of its quality.

Every modern building supposed to have a central AC, but not in Nigeria.

In Nigeria, we are not use to that kind of system and that doesnt mean that it cannot be done. We go with what is common around us?

Yes you are very correct. Central systems are most cost effective in terms of maintenance.

semitunde:


Bro. Those cooling systems are probably due for change. Though durable HVAC (Central AC) systems last for a much as 30 or more years; the maintenance and spare parts needed ( if the product is shipped from abroad) might become a problem.

@op the client determines (finally) if a building is going to have central AC or not.

HVAC systems have high initial financial outlay, but over time, compared to split ACs, their mmaintenance are more cost effective. Many clients however like to cut costs hence the choice for splits.

Hope you know the new senate building has been reverted to split AC system. Cost cutting measures.

EgunMogaji:


Obviously you lack the depth needed or you wouldn't have exposed yourself like this.

In an office yes but it in a residential edifice shown.

Obviously you lack comprehension ( as well as a basic sense of decency), else you'd have realised the topic(and thread) didnt specify anything about residential buldings, he only mentioned high rise buldings and added pictures as he deemed fit.

Besides, there's no rule anywhere that says split AC systems are strictly for residential building as you have so ignorantly posited; neither is there anything stoping any client who wants to have HVAC in his residential bulding. It's all down to the client's wants.

Finally, what makes you believe that is a residential building? Or that it is used as a residential building?

The fact that you are mostly rude and vacuous does not bully authenticity into your statements.

Are you a mechanical Engr?

It is very cost effective in terms of maintenance .Most times we aren't eager to try something new because of the huge initial cost of installation.

dubemnaija:
Our engineers don't think outside the box. They re always busy nairalanding

Answers to must questions sometimes is to think inside the box.!

drkay:
I don't think they are cost effective.

It is. It is just that the way we build our houses in Nigeria. It is different from the way the U.S build there's. Germany constructs their buildings same way as we do in Nigeria and they don't really do the central AC thing.

By the way......anyone who has projects in HVAC should feel free to contact me. Chiller maintenance, Air handlers and the likes

richiepolymer:
Do you know what VRF is?

Enlighten me.

There are quite a lot of buildings in Lagos alone tat have Central AC. But you won't notice it because its not what you're looking for.

Nigeria is used to tthe system, trust me.

Gamesmart:


You think having individual units is more cost effective than a centralised unit?

Abeg, go back to school.

That is like saying 20 people having individual cars to go to the same destination is more cost effective than 20 people sharing a big bus.

But what if the 20 people weren't going to the same destination? Cars 1-5 want to go to Ghana. Cars 6-10 want to go to South Africa. Cars 11-15 want to go to Egypt and the remaining car was to go to Ikorodu. All cars are starting from Badagry.

This is why splits are more efficient. You let each person go where they want to go without inconveniencing others. If everyone is in the family room, why condition all the bedrooms, kitchen, and bathroom? If grandma is in her bedroom and she likes warmer temperatures and you are in the living room, but like it to be cold, don't you want grandma to be comfortable?

How many houses have you built for yourself that has central AC and have you ever worked on commercial HVAC in your life?

I know down there even omolanke driver is an engineer

BE811APP:
Our architects are not innovative...No offense to dos in d proffession but its true

Why do u think Builders do a better Job on site and when I say Builders I mean those that didnt go to skol oo..

Now, this is a kind of thinking that belongs to the 16th century. If there are no designs would the builder just build from their heads? Or which kinds of Architects have you been patronizing? Maybe the quacks!

Anyways the consultants can specify and design which type of Ac to be installed but there is no strict control from the authorities on the kind of Ac to be installed. So the client can naturally change his mind.

...and how would you like the service charge to cost like 200-300k, with poor maintenance culture, the tenants will just go on and install individual Acs. How easy is it in Nigeria maintaining a central generator talkless of central Ac whether in residential or commercial buildings. Except for corporate clients who own the building and let out some offices or apartments.

Well said.

It's a shame that we have to teach grown up men that had internet access.

I'm sure some of them go around calling themselves engineers

msogunro:


Lovely in Washington D.C.

Do you guys even have AC in DC?

I know they don't have in most homes in Washington and other cold states.

Pls refer to my comment above u, so u can be corrected and stop concluding, HVAC systems have individual regulators for each rooms and can be easily controlled like split unit. There is no inconvenience except u patronize an inexperienced HVAC engineering company. Grandma would sleep well with any HVAC system.

I've been building houses an other structures ever before your hustle to become an illegal immigrant bro. Do the math yourself. No need to blow trumpets.

And 'cos you are used to omolanke contractors, ( (and still use them); does not make all contractors or Engrs dodoyos.

I will still ask, what is your claim to anything building or construction? Is it experience? Or just google? Cos I also know every morgue cleaning, restroom cleaning "sharp naija" want to be seen as enlightened even beyond their scope.

What exactly do you know about HVAC?

Really? Have you ever lived in Nigeria?

You want to transfer the inefficiency of one to all. As it is now, if your unit breaks, you are on your own. But if a central system breaks, you are at the mercy of the landlord.

EgunMogaji:

Hahahaha!! You're right about that. Many of the old homes in DC have window a/c units. Luckily, I have a renovated rowhouse with central a/c. It's horrible though. These old homes were not built for central a/c. I've actually been looking into a split unit a/c.

domack99:


If this is the case, i doubt if the idea of central AC system can sell in Naija

Central A/c is used in places like mall. Not home

EgunMogaji:


No you can't.

Yes you can. If you are ignorant about it dont embarrass your self

mathskill:


Yes you can. If you are ignorant about it dont embarrass your self

You absolutely can't.

Instead of opening your mind and get educated you're here forming enlightened

The only one embarrassing himself here is you.

I hear you.

When I lived in Texas for a while I even had two systems in place.

Split system is most efficient and Nigeria got that right for making it popular.

Story..just answer the question directly.

That you cobble up a structure for some uneducated client doesn't make you a well versed entity. I've seen the crap you lot call homes.

Try and get out of the gutter and answer questions posed to you.

Where are your friends? Are they going to join the fray?

Stop it.

You've never worked on a central HVAC in your life.

What you're describing is a commercial unit.

Nothing for me to learn from you.

Is it a question a Nigerian living in Nigeria should be asking. Where is the electricity to power such industrial AC. Do we have the maintenance culture, those that made a mistate to install it in their offices later went back to individaul separate installation because they cannot maintain it. Mind you is not that they dont have the money to maintain it but either the 'oyinbo' engineer that installed it has gone and no one else can support it or our usual manner of lack of maintenance affected it.

Maintenance is not in our culture therefore wise builders simply do the one they can maintain for the future.

It's actually a question that all Nigerians should be asking.

In this day and age where most people are going off grid from the power companies and going to solar and wind power, it makes sense to go with split system.

It's far easier to power an individual split system of say 1 ton than a central system of say 3.5 to 4 tons from battery.

Instead of our people to grasp solar and wind power they sit down there and complain about NEPA.
