Christchurch never consumed large amount of coal .... it is true the air is a bit smoggy like somewhat Beijing in Winter. They used (still do) wood fireplace for heating and quite bad in Winter ... FYI .. there is no LNG network in South Island in NZ
I disagree,households use coal as well as wood. Being close to the West coast, it would make sense to burn coal. All my Christchurch friends alternated between wood and coal. Coal was cheaper.
and even after the earthquake, new buildings are going to be coal heated which pisses off my greeny friends
"A decision to heat Christchurch Hospital's new acute services building with coal is a "bitter pill to swallow", the region's medical officer of health says.
Alistair Humphrey said it was a shame the Canterbury District Health Board (CDHB) – the South Island's largest employer – could not afford to set the example for energy use that it wanted others to follow.
"It's a bitter pill to swallow . . . we can't afford to be clean," he said.
The DHB approved the continued use of coal for two boilers to heat the hospital, including the new acute services building scheduled to open in 2018, at a meeting closed to the public in March.
Approval was also granted to build a new boilerhouse to replace the one damaged in the earthquakes and to switch from using steam to "medium hot water" for heating.
The public was excluded as cost estimates for the new boilerhouse were included in the reports, ahead of the tendering process.
Humphrey said sustainability and climate change were very important to anyone involved in the health field but cost imperatives had to be considered.
"We recognise that a coal fired burner is not a healthy way to generate heat but obviously the board, in a governance role, have to consider other factors such as cost."
In 2013/14, the Christchurch Hospital boiler house burned 8658 tonnes of coal, which produced an estimated 16,000 tonnes of carbon dioxide (Co2) emissions.
CDHB chief executive David Meates said there was a lot of misinformation about coal. Wood produced more sulphur dioxide, which was most dangerous to health, he said.......".
"Modern coal burners are very efficient and also the modern filtration plants that sit around that are actually designed to be environmentally friendly."
The decision was fully consented and supported by detailed analysis from "a range of experts", Meates said.
The two boilers, purchased as part of an upgrade in 2011, could operate on coal or a wood chip fuel.
As the two boilers were only three years old, it would have needed a very strong economic argument to replace them completely, he said.
Using wood-chip would require four truck and trailer loads to be delivered to the busy hospital site a day, compared to one delivery every second day for coal.
