Are you ready for the heating season? Have you checked your heating and dhw equipment: air vent, circulating pump and heat exchanger, etc? An annual clean and tune is essential for longevity of your equipment. B e sure to fix the band aids that helped you get through last heating season.
Green networks. Check out this study in Tucson.
In 2009 IBM launched a pilot water study that enabled residents, who recently had smart water meters installed, to visually monitor their water consumption through a web-based portal. This near real time monitoring helps households to identify leaks and benchmark their usage with other households. The goal of the study is reducing waist. The pilot study is essential to understanding households interaction with a smart meter and ensuring buy-in and ownership. Smart water meters as a standalone will not impact water consumption. “If you can get citizen buy-in and make them a part of the process, you’ll have a better project in the end,” said Dubuque Mayor Roy Buol.
Recently in the news there has been alot of talk about high efficiency motors and optimizing controls. But did you know that a simple O&M measure could increase the efficiency of your belt drive motor?
V-belts are commonly used on belt drives in rooftop exhaust fans, rooftop packaged units and make-up air fans in buildings. A low cost and short payback energy efficiency measure frequently recommended by RO is the installation of cogged belts in place of v-belts. Cogged belts have “slots that run perpendicular to the belt’s length, helping to reduce the bending resistance of the belt. While using the same pulleys as v-belts, cogged belts manage to run cooler, last longer, and increase efficiency by 2% from standard v-belts.”
Give us a call to help you determine if replacing your belts is a cost effective solution for your application.
A year-long study conducted by Pacific Northwest National Laboratory of rooftop packaged HVAC equipment at malls, hospitals and other buildings in the USA found, “Commercial buildings could cut their heating and cooling electricity use by an average of 57 percent with advanced energy-efficiency controls”.
The main goal of the campaign, http://www.advancedrtu.org, is to encourage installation of advanced controls for rooftop HVAC units. PNNL has created a table with typical HVAC unit sizes, operational characteristics and costs to help building owners “weigh the costs” of advanced controls. For instance building owners could achieve a 3 year payback with an installation of a unit that is 15 tons or less and electricity costs are greater than or equal to 12 cents per kilowatt-hour.
This blog has great photos showing the components of an in-tank WC. Save on space, energy, water and have a sleek modern design.

The In-Tank Meridian back-to-wall and wall-hung WCs are the first to have a concealed cistern integrated within the pan. Responding to the demand for quick and easy-to-install products, this clever system saves time and keeps costs to a minimum as with the tank already incorporated inside the product, no wall installation is required. The wall-hung option is supplied complete with either a straight or an L-shaped support, enabling it to be fitted to solid or cavity walls with the support frame built-in.
This innovation means that the In-Tank Meridian, already a compact option with a projection of just 595mm, requires even less installation space than a standard back-to-wall or wall-hung WC. The ideal solution for smaller bathrooms, the In-Tank offers greater…
