The Dublin Region Homeless Executive says the man found dead on a street in Dublin today had not been in contact with homeless services since 2011.
They have offered their condolences to his friends and family and say they won't be commenting further at this time.
The body of the man in his 50s was found at Ryders Row in Dublin 1 this morning.
It is the first death of a rough sleeper in 2018.
Anthony Flynn from Inner City Helping Homeless says more need to be done.
He said: "There is a concern for safety, we need extra beds, we need extra facilities, we need wrap-around support services for individuals who are rough sleeping."
Inner City Helping Homeless says the government has questions to answer about why people are still dying on our streets.
It is after the body of a homeless man in his 50s was found in Dublin 1 this morning.
He is the first reported death of a rough sleeper in 2018 after a number of deaths in 2017.
Anthony Flynn from Inner City Helping homeless says the trend cannot be allowed to continue this year.
He said: "The big question asked is: was this individual offered a bed over the last number of nights from the Dublin region homeless executive or has he been accessing any other type of services through the homeless system?
"The bigger question is: was there beds empty in the system last night and if there was why were they empty and why are people not accessing them?"
Gardaí have confirmed that a man's body has been found near Parnell Street in Dublin this morning.
It is understood that the man was sleeping rough and it is the first death of a homeless person in Ireland this year.
Gardaí have preserved the scene, which is just yards away from one of the capital's busiest streets, for a forensic examination.
Inner City Helping Homeless have responded to the tragic death, saying: "As temperatures fell below freezing last night it's a tragedy to know someone died alone in a sleeping bag on the streets of the city.
"The man was found in a sleeping bag on Ryder's Row near Parnell Street. This death once again highlights the question of why someone would rather sleep on the streets than in emergency accommodation provided by the DRHE.
"Trust in the hostel system is still a huge issue as many feel safer on the streets than they do in State-provided accommodation. When that is the case there are serious questions to be asked. It cannot be socially acceptable to go into another year of people dying on our streets."
ICHH CEO Anthony Flynn said it shows the harsh reality of homelessness.
He said: "Last night's weather conditions were extremely cold and no person should be in a position where they have to sleep rough.
"The question needs to be asked how many beds were left empty and why this person felt the need to sleep rough. The system is continuously failing."
