Work has begun on a state-of-the-art carbon-neutral training facility for military dogs and their handlers.
The new building at the Defence Animal Training Regiment (DATR) in Melton Mowbray, Leicestershire, should be finished by October and will be 96% self-sustaining.
The new facility will replace the portable buildings currently housing the squadron's HQ staff and the 1940s timber-framed buildings that are used for training military working dogs and their handlers.
Green features of the building will include sustainable insulation in the walls and roof, 'air-lock' doors that will prevent heat from escaping and six solar panels.
A battery storage facility will also generate the building's own electricity needs.
A heat recovery system in the plant room and network room will be used to heat the offices and training facilities, while a rainwater recycling system will collect, save and reuse water in a bid to reduce the use of the mains water supply by up to 60%.
Rainwater will also be used for cleaning soldiers' boots and bike racks will be built to encourage people to cycle to work.
Commanding Officer of the DATR, Lieutenant Colonel Martyn Thompson, said: "The planning, design and sustainability of this project will generate much-needed efficiencies in our training delivery.
"This will ensure that the DATR continues to provide defence with a proven capability which helps to protect our people, territories, values and interests at home and overseas."
The new ecological and cost-saving facility will help achieve the Army's commitment to meet net carbon emissions by 2050, the service said.
It comes after the Ministry of Defence (MOD) published a report detailing the dangers of climate change to defence.
The report author Lieutenant General Richard Nugee, MOD Climate Change and Sustainability Lead, said: "Climate change is just as much a threat to global security as more conventional threats."
The internal construction of the building means that once its use is over in its current capability, it can be re-purposed for another use without the need for rebuilding, the Army added.
