Most site huts occupied by building construction companies are very basic. Kettles, fridges and air-conditioning are usually the only concessions to comfort while little consideration is given to conserving energy, as most adopt a “Will the last person shut the lights off” approach.

But not anymore. Adelaide construction company Built Environs has turned that concept on its head.

The company’s temporary site office at the Edinburgh RAAF Base LEAP (Living Environment Accommodation Precinct) is fitted with state of the art C-Bus lighting control technology, motion sensors, timers and sunset switches. It is designed and programmed to conserve as much energy as possible.

The office even collects rain water which is used to maintain a vegetable garden that staff and contractors tend to during work breaks.

“We wanted to reduce our carbon footprint,” says Built Environs project manager Tony Jachmann.

“It’s a culture we decided to adopt even in our construction site huts. Normally in these temporary offices, we would have the lights and air-con going 24/7. Our LEAP Project office is actually five shells bolted together and this project is not due for completion until 2013, so that’s a lot of energy that would go to waste.”

After discussions with Tony Fagan, CIS Sales Manager, Clipsal by Schneider Electric, and C-Bus Approved Installer Andrew Fragnito, from DVISE Solutions, the team designed and implemented a C-Bus lighting control system. C-Bus provides master on and off switching, it activates designated lighting in common areas, and times out lights with motion sensors in isolated offices, kitchen and lunch areas.

The system cleverly bypasses the staff fridge and times the hot water boiler to activate first thing in the morning. C-Bus even activates air-conditioning units at 5am, prior to staff arriving for work and times them out in the evening at 6.30pm when the site office is no longer occupied.

“It was an unusual but not a difficult job for our team to wire,” Andrew says.

“The office shells were already pre-wired so we had to run surface conduit down the walls to accommodate the C-Bus wiring. Programming the system was straight forward. We installed a C-Bus Wiser system. This enables Tony to check the status of the lighting and manually override the system via his iPhone.

“It’s a clever app and gives Tony options to control the system and even monitor energy consumption.”

The C-Bus system is very flexible and can be reconfigured and programmed for any future need.

“These huts we use, we reuse,” Tony says.

“When we are finished, we will unbolt it and use it again for the next project. It’s worked out well. The system is user friendly and we know we’re saving energy.”

Tony Fagan estimates that Built Environs energy savings are significant.

“We believe at the very least that the client is currently achieving energy savings of at least 30%. Importantly, they are walking the talk and creating a genuine energy efficiency culture.”

As for the veggie patch which is currently abundant with tomatoes, cucumbers and watermelons, “It was an interesting concept which just started with an idea, said Tony Jachmann.

“We had the rain water and decided to start a garden. Not everyone has an iced coffee or smokes during their break, however they enjoy a bit of time out, watering the garden and looking after the plants. It breaks the day and fits in well with the low carbon direction we are taking.”
