What does razred mean in this sentence?

Here razred means class, category, or rating.

So razred energetske učinkovitosti is the energy efficiency class/rating of something, such as an appliance or building.

A useful thing to remember is that razred can also mean school class in other contexts, but here it is clearly a technical label or category.

Why is it energetske učinkovitosti and not energetska učinkovitost?

Because after razred Croatian uses a structure that works like class of energy efficiency.

That means energetska učinkovitost changes into the genitive case:

• nominative: energetska učinkovitost
• genitive: energetske učinkovitosti

So:

• razred = class
• energetske učinkovitosti = of energy efficiency

This is very common in Croatian: one noun is followed by another noun in the genitive to show of.
