Energy efficient or efficiency

Question

I would like to seek someone to resolve the below question. Thank You

The below sentence is an excerpt from a webpage.
Energy Assessors are at the forefront of the market because they hold the knowledge and practical experience to make your building more energy efficient.

1. Energy (noun) efficient (adj)
2. Energy (noun) efficiency (noun)

Which one is correct/ both are correct?
Is energy in item 2 as an noun modifier?
What is the difference of both items?

Energy efficient is correct in your sentence because an adjective is needed in it. Energy efficiency can be used as the subject of a sentence, for example: Energy efficiency is very important nowadays.

efficiency is a noun.
efficient is an adjective.

Efficiency is the property of being efficient.

You don't say, "to make your building tallness" or "to make your building beauty", do you?
No, because 'tallness' and 'beauty' are nouns.
You say, "to make your building tall" or "to make your building beautiful", because you need adjectives there to describe how you want the building to look.
Therefore, you need "to make your building efficient".

'comments on energy efficiency' is correct. This is just as you would say, "comments on beauty", not "comments on beautiful".

You are describing the resource in your third example, so you need an adjective. 'the energy efficient resource'. You wouldn't say "the beauty woman". You'd say "the beautiful woman".

I have question about the last example.

S1}...to make energy efficiency resource more real...

S2}... to make building more beautiful...

Energy efficiency resource (S1) is a noun and same as building (S2). Real & beautiful also act as an adjective in the phase. In my opinion, energy efficiency resource is better than energy efficient resource. Do you agree? Please share your opinion.

Ben9108energy efficiency resource is better than energy efficient resource. Do you agree? Please share your opinion.

In this example you can use either version, but the meaning will change slightly. You will have to decide for yourself how you want to express your idea.

energy efficient resource ~ The resource itself, whatever it is, is efficient with regard to the expenditure of energy.
energy efficiency resource ~ The resource, whatever it is, is a means of achieving efficiency in the use of energy.

Perhaps you do intend the second of these, but as I say, you are the one who knows what you want to say, not me, so you'll have to make the decision.

I have similar problem about the adverb and adjective usage shown below.

The Contractor shall make available to all its staff such contractual requirements to enable all of the Employer’s and Contractor’s staff to carry out their jobs efficiently and effectively.

Please comment and share your opinion for the rewriting sentence below.

… Contractor’s staff to carry out their jobs efficient and effective.

This is wrong. Efficient and effective are describing carry out, a (phrasal) verb, so they need to be in their adverbial forms, efficiently and effectively.

As C Snyder has said, it has to be 'efficiently and effectively'. That's the only correct way to do it.
