Υπολογίζουμε κατά πόσο η εξωτερική θερμομόνωση αυξάνει την εξοικονόμηση ενέργειας.

Υπολογίζουμε is the 1st person plural present tense of υπολογίζω.

So it means we calculate, we estimate, or sometimes we assess, depending on context.

In this sentence, it sounds like:

• we calculate
• we assess
• we determine

The ending -ουμε is a very common way to mark we in Modern Greek verbs.

Greek often uses the 1st person plural in formal, academic, technical, or scientific language where English might also use:

• we calculate
• we estimate
• we examine

This does not always mean a specific group of people in a personal sense. It can be a neutral, formal way to present a process or analysis.

So Υπολογίζουμε... can sound like:

• We calculate...
• We assess...
• The analysis calculates/assesses...

depending on style.

κατά πόσο means to what extent, whether and to what degree, or how far.

It introduces an indirect question about degree or extent.

So:

• Υπολογίζουμε κατά πόσο... = We calculate/assess to what extent...

This is a very useful expression in formal Greek.

Compare:

• αν = whether / if
• κατά πόσο = whether and to what extent

So κατά πόσο is more precise when the issue is not just yes or no, but how much.

η is the feminine singular definite article, meaning the.

The noun θερμομόνωση is feminine, so it takes:

• η in the nominative singular

That is why we get:

• η εξωτερική θερμομόνωση
• the external insulation / the exterior thermal insulation

The adjective εξωτερική is also feminine singular nominative, so it agrees with θερμομόνωση.

It is the subject because:

1. It is in the nominative case:

   • η εξωτερική θερμομόνωση

2. The verb αυξάνει is singular, and the subject is also singular.

3. Semantically, it is the thing doing the increasing:

   • the external insulation increases...

So the structure is:

• Υπολογίζουμε = main verb
• κατά πόσο = introduces the indirect question
• η εξωτερική θερμομόνωση = subject of αυξάνει
• αυξάνει = increases
• την εξοικονόμηση ενέργειας = object

θερμομόνωση means thermal insulation.

It is a compound-like formation built from:

• θερμο- = heat / thermal
• μόνωση = insulation / isolation

So literally it is something like heat-insulation, but in natural English we say thermal insulation.

In this sentence, εξωτερική θερμομόνωση means external/exterior thermal insulation, such as insulation added to the outside of a building.

In Greek, adjectives often come before the noun, especially in neutral descriptive phrasing.

So:

• η εξωτερική θερμομόνωση = the external insulation

This is the most natural order here.

Greek adjectives can sometimes come after the noun, but before-the-noun placement is extremely common and normal.

αυξάνει is the 3rd person singular present tense of αυξάνω.

It means:

• he/she/it increases
• or increases with a noun subject

Here the subject is η εξωτερική θερμομόνωση, so:

• η εξωτερική θερμομόνωση αυξάνει = the external insulation increases

Notice the agreement:

• singular subject
• singular verb

Because αυξάνω is the dictionary form / 1st person singular:

• I increase

But the subject here is η εξωτερική θερμομόνωση = the external insulation, which is 3rd person singular.

So Greek uses:

• αυξάνει = it increases

Compare:

• αυξάνω = I increase
• αυξάνεις = you increase
• αυξάνει = he/she/it increases

Because it is the direct object of αυξάνει.

The verb αυξάνει takes an object in the accusative case:

• την εξοικονόμηση

So:

• η εξωτερική θερμομόνωση αυξάνει την εξοικονόμηση ενέργειας = the external insulation increases energy savings

The article την shows that εξοικονόμηση is feminine singular accusative.

Because the phrase means energy saving / saving of energy.

• την εξοικονόμηση = the saving / the conservation
• ενέργειας = of energy

So ενέργειας is in the genitive singular, expressing a relationship similar to English of energy.

This is very common in Greek:

• εξοικονόμηση ενέργειας = energy saving
• literally: saving of energy

So the full object is:

• την εξοικονόμηση ενέργειας = the energy saving / the saving of energy

Not necessarily. Literally, yes, it is saving of energy, but natural English usually prefers:

• energy saving
• energy savings
• energy conservation

The best translation depends on context.

In this sentence, αυξάνει την εξοικονόμηση ενέργειας is most naturally:

• increases energy savings or
• improves energy conservation

Greek often uses noun phrases with a genitive where English may prefer a compound noun.

Greek verbs already contain the necessary information about person and number, so extra helping words are often unnecessary.

For example:

• Υπολογίζουμε already means we calculate
• αυξάνει already means it increases

English often needs support words in some structures, but Greek usually packs more information directly into the verb ending.

Yes, Greek word order is more flexible than English word order, because case endings and verb forms help show grammatical roles.

The original order is natural and clear:

• Υπολογίζουμε κατά πόσο η εξωτερική θερμομόνωση αυξάνει την εξοικονόμηση ενέργειας.

But Greek could move elements around for emphasis, for example:

• Υπολογίζουμε την εξοικονόμηση ενέργειας κατά πόσο την αυξάνει η εξωτερική θερμομόνωση.

That version is much less neutral and less straightforward, but grammatically possible in the right context.

So the original sentence is the best standard phrasing.

Not exactly.

• εξωτερική θερμομόνωση is a fixed, natural noun phrase meaning external thermal insulation
• θερμομόνωση εξωτερικά sounds more like insulation externally / insulation on the outside

The first is the normal technical term.
So if you are talking about the concept or system itself, εξωτερική θερμομόνωση is the preferred wording.

πόσο by itself usually means how much or how many.

But κατά πόσο is a set expression meaning:

• to what extent
• whether and to what degree

So:

• πόσο αυξάνει; = how much does it increase?

• υπολογίζουμε κατά πόσο αυξάνει = we assess to what extent it increases

The version with κατά is more formal and more idiomatic in this type of sentence.

A helpful breakdown is:

• Υπολογίζουμε = We calculate / We assess

• κατά πόσο = to what extent

• η εξωτερική θερμομόνωση = the external thermal insulation

• αυξάνει = increases

• την εξοικονόμηση ενέργειας = energy savings / the saving of energy

So the sentence structure is:

main verb + indirect-question phrase + subject + verb + object

That is why the whole sentence means something like:

We assess to what extent external thermal insulation increases energy savings.
