Creating a Collaborative Workspace Without Breaking the Peace

Meeting Room

The rise of the cubicle in the 1960s and ’70s began from a desire for private workspaces. They became so popular that offices used to look like cubicle farms, until these row-upon-row ‘bullpens’ began to draw criticism for their appearance and their limitations on peer interaction and collaboration. Over time, the walls came down and cubicles were abandoned to make workplaces more open and friendly.

The average hospital uses three times the energy of typical commercial buildings, and U.S. medical facilities spend $8.8 billion annually on energy. Between lighting, medical equipment, HVAC, and plumbing, energy consumption in medical facilities outpaces any other type of building. For large hospital systems, annual costs can reach into the tens of millions of dollars—no small amount in an industry of thin margins.

Variable refrigerant flow (VRF) HVAC zoning and geothermal systems are two of the most energy-efficient options for heating and cooling available—now, new hybrid assemblies combine the two. This article provides an overview of geothermal (or water-source) with VRF zoning technology and its advantages compared to traditional geothermal systems, air-source VRF zoning systems and conventional HVAC systems. In addition, the article will discuss considerations for specifying water-source VRF zoning systems and provide case studies of successful applications.

New technologies can provide optimal natatorium environmental control and energy savings. Today’s indoor pool dehumidifiers and outside air ventilation systems technology has changed so much over the last decade, a new or retrofitted natatorium stands to save millions of dollars in energy costs over the 15 to 25-year lifecycle of the equipment. Equipment comes with reduced refrigerant charges of up to 85-percent, compressor heat recovery for free pool water heating, exhaust heat recovery for preheating outdoor air, modulating controls for pinpoint temperature and humidity control, glycol heat rejection to dry coolers, and web-based microprocessor monitor, alarms, and control for factory technician review.
