Making a house 'airtight' with effective insulation is key to creating a zero-carbon home, it has been suggested.
Home heating pundit Zolton Cohen explained that much of the heat produced in such a building comes from lighting fixtures, waste heat from appliances and even the 'body warmth' given off by the people inside.
"Zero- and low-energy houses produce as much energy as their occupants consume," he explained to US publication the Kalamazoo Gazette.
"They are insulated and air-sealed to the point that they need very little additional input from a heating or cooling unit," he added.
Mr Cohen noted that maximum energy efficiency can be achieved by "a lot of engineering and planning" ahead of home improvements or construction, with heating needs accurately calculated and insulation carried out "with precision and care".
He concluded that individuals keen on cutting carbon emissions to zero need insulation levels in the walls and ceilings "that exceed the minimum required in conventional homes".
DIY specialist Donny Sheridan recently reiterated to the UK's Sunday Mail that home insulation is no longer simply an option – it is a "must" in the face of rising carbon emissions.
Double glazing is proven to save heat and energy lost through poorly-insulated windows and doors. With Energy Efficiency windows and doors as standard, homeowners can now save even more on their heating bills and reduce their carbon footprint.
