Customizable controls package effectively integrates several mechanical systems from a single source.


LEESBURG, Va., October 10, 2012 – As the owner of both a home and mechanical contracting business, David Bednarski recognizes significant value in a customizable controls package that can effectively integrate operation of several mechanical systems from a single source. Bednarski’s own 5,500 square foot (510 square meter) home, originally built in 1977 with a forced air system, has been retrofitted over the past five years with a sophisticated mechanical system that includes a number of interdependent renewable energy sources and HVAC components.

“The home’s new system is designed as a model for what can be achieved by integrating an array of mechanical technologies – including the latest and greatest in sustainable energy and energy efficient systems – in such a way as to minimize the use of fossil fuels, while also achieving a consistently comfortable indoor environment,” Bednarski said. “To achieve the maximum efficiency of a system like this, however, it’s of utmost importance that you have a controls system with the flexibility and capacity to ‘help’ these systems work together in an optimized way.”

According to Bednarski, the REHAU Smart Controls system, which was recently retrofitted into his home’s existing mechanical system, provides unique and customizable features that allow for all systems to work in a seamless manner.

“In its entirety, the mechanical system includes solar thermal, geothermal, photovoltaic and boiler back-up energy sources, as well as a radiant heating and cooling system, humidity controls, direct hot water production and recirculation, fan coils and buffer tanks,” said Bednarski. “That’s a lot for one house, let alone one controls system. Many controls just don’t have the breadth and technical sophistication to understand how all the individual components should be operating at any given time, and because of this there’s often a lot of conflict and redundancy among them. The REHAU Smart Controls system is the first I’ve ever seen that provides true system integration and optimization, and all from a single source.”

Bednarski was able to program the customizable features of the REHAU Smart Controls system to automatically engage his home’s most ideal energy source/sources during particular operating conditions, maximizing the total efficiency of each element’s function within the mechanical system.

“In addition to its technical breadth, the REHAU Smart Controls system is so incredibly flexible,” he said. “I can design a system that’s half the size of the one in my house, or four times bigger, or with all different types of HVAC components, and REHAU Smart Controls can accommodate it all.”
