In terms of Btu per square foot, for example, U. The high energy requirement in the health care sector makes health care facilities particularly vulnerable to increases in the cost of fossil fuels. Fossil fuels are expected to provide a significant portion of this energy demand well into the future.
Consistent with economic principles, as crude oil becomes more difficult to source, price is expected to increase. According to a report from the World Energy Council, the peak of the world crude oil discovery was in the s and has been declining ever since. Overview The energy-related sections of the Roadmap website are generally framed around reductions in consumption of energy derived from fossil fuels.
Energy reductions can be considered a proxy for reductions in greenhouse gas GHG emissions, since emissions from fossil fuels are by far the largest source of emissions from hospitals, typically around 95 percent.
If fossil fuel consumption is reduced, emissions are reduced. Defining the targets in this way allows the analysis to consider on-site renewable energy, energy demand reductions, utility company renewable supply sources, and even Renewable Energy Credits to help a facility realize its goals to reduce both energy and emissions.
It allows maximum flexibility to users at the same time it achieves real reductions. In light of this approach, it is useful to provide some further context specific to greenhouse gas GHG emissions. Some organizations may find it worthwhile to report on both energy consumption and GHG emissions, and it may soon be a requirement to do so.
Health care organizations produce GHG emissions through travel, building energy use, and procurement of goods, equipment, and materials.
In general, modern health care practices in industrialized economies are highly energy intensive due to sophisticated buildings, high levels of product procurement, and transportation-related activities, which all rely heavily on the use of fossil fuels for energy.
In the U. GHG emissions from facility energy use are attributed to operations such as fuel consumption for provision of heating and electricity and anesthetic gas discharge.
The type of fuel used for heating and the fuel source used to generate electricity will have a significant effect on the level of GHG emissions associated with building operations. Due to the high energy intensity of the U. Scope of Greenhouse Gas Emissions.
GHG emissions are generally broken down into three categories, or scopes: Scope 1 emissions are those that occur from sources owned or controlled by the institution and can include on-site stationary combustion of fossil fuels, mobile combustion of fossil fuels by fleet vehicles, and fugitive emissions.
Fugitive emissions are those caused by intentional or unintentional releases of GHGs, which include refrigerant leakage and waste anesthetic gas discharge. Scope 2 emissions include indirect emissions generated as a result of the off-site production of electricity that is consumed by an entity.
These emissions occur as part of the process of producing the electricity e. Scope 3 emissions are indirect emissions that occur as a consequence of an entity's activities but come from sources outside the control of the organization.
In most GHG reporting protocolsonly Scope 1 and Scope 2 emissions are included in the inventory due to the difficulty of measuring Scope 3 types.
In a typical health care facility, the largest sources of Scope 1 and Scope 2 emissions are related to electricity and natural gas consumption. In most cases, this accounts for more than 95 percent of the inventory. For this reason, energy can be used as a proxy for GHG emissions within a typical health care facility.
The Roadmap follows this model in providing guidance for target-setting and project implementation. Energy Supply Terminology and Strategies Demand vs. There are two general approaches to reducing energy consumption and associated GHG emissions: Demand side strategies focus on reducing a facility's demand for energy through efficiency improvements.
Supply side strategies focus on reducing the amount of fossil fuel-derived energy used by the facility. This is achieved by providing renewable, non-fossil fuel-generated energy, which can be generated on-site or off-site. It is also important to understand the difference between site- and source-measured energy.
Site energy refers to energy consumption measured at the site level by utility meters. Source energy, on the other hand, refers to energy generated at the source i.
For electricity, source energy can be on average three times greater than site energy due to losses through transmission and distribution. Power mix and the renewable portfolio standard: The power mix refers to the combined makeup of fuel sources used by the utility in electricity generation and can include coal, natural gas, nuclear, wind, solar, geothermal, biomass, and hydroelectric plants.
Most states have established a policy, called a renewable portfolio standard RPSthat requires utility providers to generate a certain portion of their electricity from renewable sources.Delivering Utility Savings Worldwide.
