Reducing Utility Costs of Ventilation Air

Ventilation load can be a significant portion of a building’s heating and cooling load and subsequently a building’s utility costs. Finding ways to reduce the energy use associated with ventilation load can greatly reduce these costs. Two methods of reducing these energy costs are to utilize energy recovery ventilation equipment or demand control ventilation. Energy

Low-Flow Fixtures Can Be A Hot Topic

Energy/utility savings are becoming more prevalent in building managers’ roles in reducing their facility’s operational costs. Water consumption savings are attractive with the latest in low-flow plumbing fixtures, and the consumption savings trickle into reduced water heating capacity too. Although it may seem like a simple task in specifying low-flow fixtures or even replacing plumbing

Understanding Laboratory Plumbing Systems

When designing plumbing systems for science laboratories certain requirements such as space planning, code compliance and user’s needs must be considered. Acid waste, natural gas, reverse osmosis/deionized water, compressed air and vacuum are the most common plumbing systems utilized in science laboratories. The most important part of science laboratory system design is coordination between the

Fire Protection Antifreeze Systems

The coming of winter requires the Building Owners and Managers to review their buildings and systems for protection against freezing. However, there is one building system that may already be freeze protected and should be reviewed due to recent developments – sprinkler antifreeze systems. Based upon reports of a fire incident involving a sprinkler system
