The federal health department is being urged to review its treatment of patients who present with symptoms potentially linked to mould.
A recent inquiry called for clinical guidelines to be developed for GPs and medical practitioners to better diagnose mould-related conditions.
Medical experts said many GPs are unaware of the symptoms or conditions linked to toxic mould, with many clinical diagnosis tests only available overseas.
The committee's chair, Liberal MP Trent Zimmerman, said the recommendations were aimed at helping sufferers of chronic inflammatory response syndrome, the name for the range of conditions brought on by toxic mould.
"There is consensus that there are people who suffer from a range of complex symptoms that are debilitating, difficult to diagnose and treat effectively," Mr Zimmerman said.
"For these people, being unable to obtain a definitive diagnosis and consequently recover from conditions often ascribed to chronic inflammatory response syndrome that can have a significant and ongoing impact on their quality of life."
Other recommendations put forward by the committee included developing standards and conducting further research into mould testing, providing tenants with information about mould history for their rental properties, and researching building codes in relation to mould.
The inquiry was brought forward by NSW Liberal MP Lucy Wicks, who suffers from chronic inflammatory response syndrome after a tree crashed through her Central Coast home in 2015 leaving the property with water damage and exposed to mould.
"I got very, very tired and got asthma, which I had never had before," Ms Wicks said.
"I was tired all the time and the fatigue was very great. I went from being fit to being unable to do lots of things. My skin would become sensitive when I walked into certain buildings."
Ms Wicks's condition meant most of her meetings in her electorate were conducted outside and also meant there were parts of Parliament House she couldn't access due to mould-related issues, among them the Prime Minister's office, she said.
"Some environments are very challenging, there were certain rooms that I would avoid. My body would stabilise when I was clear of mouldy areas," Ms Wicks said.
"When you're affected, your body goes into overdrive trying to get rid of it. It felt like I was being poisoned or on fire. At times I felt my brain was on fire."
A Department of Parliamentary Services spokeswoman said she was unaware of mould issues in Parliament House and air quality audits were conducted every six months.
"From time to time, there will be isolated instances of mould detected from localised factors where infrastructure components fail. However, these are not attributed to building mould," the spokeswoman said.
Other national institutions in Canberra have reported cases of mould, with two in the past five years at the National Library, the 50-year-old building on Parkes Place.
A library spokeswoman said mould usually detected in its collection arrived on donated material and was mostly inactive.
An Old Parliament House spokesman said there had been two cases of mould in the 91-year-old building since 2009. However, the mould detected was not in any of the original parts of the building.
The youngest of Canberra's national institutions, the National Portrait Gallery, reported no cases of mould detected since the building was opened 10 years ago.
Ms Wicks was diagnosed after seeing her mother suffer from chronic-fatigue related symptoms for almost 20 years.
Upon her mother's advice, Ms Wicks saw a doctor about the issue and was diagnosed.
She said the inquiry was an important step in getting help for sufferers and making it easier for those who would be diagnosed in the future.

"The first area that I would like to see is clinical guidelines for GPs so anyone who found themselves being or had protracted an illness like this could receive help," Ms Wicks said.
"I would love to see state and territory governments take the issue very seriously, particularly in relation to water-damaged environments, and better legislation for tenants."
Support for sufferers in months and years to come was one of the key reasons behind the inquiry. For those living with the condition, support largely comes through online groups.
Toxic Mould Support Australia is a Facebook group with almost 4000 members, many sharing tips and advice on how to manage symptoms.
Brisbane resident Caleb Rudd is an administrator of the page. He said the group had proved helpful to many.
"Most of the people who join the group usually have some form of chronic illness or caring for someone who does," Mr Rudd said.
"What we can do is validate their illness and symptoms and help point them in the right direction."
Mr Rudd has suffered from symptoms related to chronic inflammatory response syndrome since 2014. He said the group had grown substantially this year as more people became aware of the effects of toxic mould.
"More people are putting two and two together about having mouldy houses and chronic symptoms, and ideally we can be part of the prevention and not just the support," he said.
Mr Rudd said the government inquiry had been a major step forward for sufferers and many hoped it would be able to lead to lasting change in the area.
The federal government is considering whether to implement all seven recommendations put forward by the inquiry.
Ms Wicks said more information had been gathered about the condition every day. She hoped the inquiry would lead to others being diagnosed sooner.
"This report validates the experiences of hundreds of people that have contacted me with their stories and experiences," she said.
"It lets people know who are suffering with this particular condition is that their voice is being heard."
Rising levels of mould-related illnesses and toxic mould cases in homes has led to a surge in call outs across the country for building biologists.
A relatively recent industry, building biologists investigate health hazards in homes and other built environments, with many hazards linked to chronic illnesses and conditions such as asthma.
A recent study of members of the Australian Society of Building Biologists found 65 per cent of cases were mould related.
The society's president Narelle McDonald said many mould cases inspected by building biologists came from new homes.
"Because the building standards have been tightened, we haven't considered how water vapour migrates out of buildings, and we see lots of issues in new buildings with condensation that leads to mould," Ms McDonald said.
"I expect mould cases to grow even more substantially. We're seeing so many cases of people with issues."
There are more than 100 building biologists across the country, although none are permanently based in Canberra.
The society's vice-president Nicole Bijlsma has been in the field for almost 20 years.
She said half of all homes that suffer some levels of water damage would have mould-related issues.
"Our job is to investigate the health hazards people have in their home and how exposure can be reduced," she said.
"When moisture made from building occupants go through walls and cause hidden mould issues in homes, that's a real issue, and we urgently need changes to the national construction code to address these issues."
This is part of a series on the effects of mould on health and homes.
