The energy needed to run commercial and industrial buildings in the United States produces 19 percent of U. The healthcare sector is in need of cost effective solutions to address the rising cost of energy and the health implications of energy use.
Once a facility has developed an energy baseline by tracking and measuring its energy useit can begin to zero in on key areas of inefficiency and review potential energy reduction strategies with an eye for what will work given the financial resources of the organization.
Displacing the use of conventional energy with clean, renewable energy reduces GHG emissions and contributes to softening price volatility associated with oil, natural gas, coal and electricity generated from these fuels. Demand-Side Management Demand-side management is a facilities management approach that involves ways to reduce the need for energy.
The key in demand-side management is conservation through system-wide energy conservation programs. These types of programs identify cost-effective procedures that reduce energy consumption and develop systematic programs of energy system efficiency improvements. Healthcare facilities examine and analyze energy use to determine where it could be possible to cut back.
There are several key areas a healthcare facility can target when looking for energy efficiencies. The following areas are the energy use categories laid out by EnergyStar and provide a useful framework for assessing opportunities for energy reduction: Commissioning usually takes place when the building goes into service.
Lighting Lighting consumes close to 35 percent of the electricity used in commercial buildings in the United States and affects other building systems through its electrical requirements and the waste heat that it produces. Upgrading lighting systems with efficient light sources, fixtures, and controls can reduce lighting energy use, improve the visual environment, and affect the sizing of HVAC and electrical systems.
Looking at the intensity of lighting in different areas—i. Supplemental Load Reduction Supplemental load sources are secondary load contributors to energy consumption in buildings—typically people, computers, lights, and the building itself. These loads can adversely affect heating, cooling, and electric loads.
However, the effect of supplemental loads can be controlled and reduced through strategic planning and implementing energy-efficient upgrades.
With careful analysis of these sources and their interactions with HVAC systems, equipment size and upgrade costs can be reduced. These upgrades can increase HVAC energy savings and reduce wasted energy.
The best ways to reduce supplemental loads include: Reducing equipment energy use Air Distribution Systems On average, the fans that move conditioned air through healthcare institutions account for about 8 percent of the total energy consumed by these buildings, so reductions in fan consumption can result in significant energy savings.
Environmental Protection Agency EPA study found that almost 60 percent of building fan systems were oversized by at least 10 percent, with an average oversizing of 60 percent. There are also opportunities for energy-saving improvements to the air distribution system in four other categories: Adjusting ventilation to conform with code requirements or occupant needs, Implementing energy-saving controls, Taking advantage of free cooling where possible, and Optimizing the efficiency of distribution system components.
However, it is possible to lessen this impact in both central and unitary systems by increasing their efficiency. Although their higher capacities often translate into more opportunities for savings from cooling systems, significant savings can still be had from heating systems.Facilities Management Good Practice Guide Facilities Management Good Practice Guide Version | August construction, operations, maintenance, management and administration of multi-unit ensuring the building is a great place to live and work.
