The West London side's 2-2 draw at Millwall on Saturday was the first time in eight games the Hoops had conceded - a club record - and their mean defence has helped the club to second in the Championship table, as they aim to claim an immediate return to the Premier League.
Relegation from the top flight last season was hard to take, says Green, but the keeper who has 12 England caps to his name, says a summer overhaul by boss Harry Redknapp has transformed the club into a formidable outfit once again.
"We've had a huge turnaround, a huge turnaround of players," Green, who has only conceded four times in the league this year, told Goals on Sunday.
"We had something like 30 players in or out in the summer and so far this season's been brilliant. We're in a league below but the winning feeling... well, you can't beat it. It makes your weekend and your life a bit easier.
"Yesterday was a disappointing result because it feels like a loss rather than a draw but in the greater scheme of things we're still unbeaten and still going well."
Between QPR's 1-0 win over Ipswich in August and their 2-0 win at home to Barnsley in early October, Green set a new benchmark for clean sheets at the club, with eight shutouts.
However, the shot stopper modestly deflected much of the responsibility for that record onto his defence, which this season has been marshalled by Richard Dunne and skipper Clint Hill.
And Green says a common language between him and his back four - which wasn't always the case in QPR's side last term - has had a big impact.
"I've only had to make pretty routine saves, really, and the work I've had to do has been pretty minimal because of the guys in front of me, who have been so good," said Green.
"Obviously yesterday was a disappointment because we conceded two goals, but realistically conceding just four goals in eleven games has been brilliant.
"What helps is everyone speaks the same language. That was the problem last season - there were so many different languages, so many barriers to overcome to get the message across.
"In the heat of the moment you speak to someone for whom English isn't their first language and they've got to translate it into another language and then translate it back to respond - and by then the moment is gone.
"We've also got the experience of Hilly and Dunney which makes a huge difference and everyone knows where they should be, which makes my life a whole lot easier."
Reflecting on Saturday's point at the Den, Green was keen to take the positives out of his side's performance and pointed out the club's passing statistics demonstrate the talent in their ranks this term.
"We dominated much of the game yesterday, apart from their little spell when they got their first goal," he said.
"They threw everything at us at the end and got a lucky bounce and produced a great finish to get the draw - but that's what happens sometimes.
"It feels like a defeat but at the end of the season we could look at it as a point gained.
"The boss was disappointed we didn't control the game right through to the final whistle but our passing has been brilliant all season - we make 600 passes a game which at Championship level is an incredible stat. It's unheard of.
"We just need to start another run now."
