Imagine high-rise, modern structures with many square metres of glass being able to controls energy by opening and closing automatically as temperatures change. This is a principle that has been used for greenhouse ventilation for many years. A German architect asked the question
“If it works for greenhouses then can the system be developed for commercial buildings?”

⑥ USA: Articulated Truck And Scraper
Puts Bypass Ahead Of Schedule
The 13-person excavating crew from C.J. Moyna & Sons, Inc. has 240 working days to move 918,000 m³ (1.2 million yd³) of earth at the Southwest Arterial, an Iowa Department of Transportation bypass around Dubuque.
No problem. Dan Harwick, project superintendent, C.J. Moyna & Sons said:
“So far, we’re ahead of schedule. We were allotted 240 days. We will finish way before that, depending on the weather, of course. The early completion date is definitely because of the type of equipment we’re using. We’re able to move a lot of dirt—fast and efficiently.”
The crew is using five Mobile Track Solutions (MTS) Articulated Truck and Scraper Pull Pan Combinations, in which a Cat 745 Articulated Truck chassis is converted from a dump body configuration to a scraper power unit.
