The most conventional way biomass is used however, still relies on direct incineration.

Blended Value: Blended value represents a broader way of thinking about the nature of value creation by organizations, whether for-profit, nonprofit or hybrid, and through the application of capital. Emerson coined the “blended value” term to transcend the previously bifurcated definitions of value as either economic or social/environmental so that the focus could shift to maximizing companies, communities and capital.

Building Automation : Describes the functionality provided by the control system of a building. A building automation system (BAS) is an example of a distributed control system. The control system is a computerized, intelligent network of electronic devices, designed to monitor and control the mechanical and lighting systems in a building. BAS core functionality keeps the building climate within a specified range, provides lighting based on an occupancy schedule, and monitors system performance and device failures and provides email and/or text notifications to building engineering staff. The BAS functionality reduces building energy and maintenance costs when compared to a non-controlled building. Buildings with these systems are sometimes called “Smart Buildings.”

Building Information Modeling (BIM): The process of generating and managing building data during its life cycle. Typically it uses three-dimensional, real-time, dynamic building modeling software to increase productivity in building design and construction. The process produces the Building Information Model (also abbreviated BIM), which encompasses building geometry, spatial relationships, geographic information, and quantities and properties of building components.

Climate Adaptation Planning: The development of strategies that attempt to reduce a community’s vulnerability to climate change. Adaptation planning differs from climate-change mitigation planning in that it does not attempt to reduce or avoid climate change. Instead, it assumes that climate change is unavoidable and attempts to develop a plan for dealing with the expected local consequences. (See Resilience.)

Combined Heat and Power (CHP): Using the waste heat which is a by-product of energy production to heat space.

Community Choice Aggregation or CCA: A system adopted into law in the states of Massachusetts, Ohio, California, New Jersey and Rhode Island, among others, which allows cities and counties to aggregate the buying power of individual customers within a defined jurisdiction in order to secure alternative energy supply contracts. Currently, nearly one million Americans receive service from CCAs.

Corporate Social Responsibility (CSR): A form of corporate self-regulation that is integrated into the business model and takes into account not only shareholders but also stakeholders such as employees and customers. CSR efforts often include the entire value chain, including suppliers, buyers The term “corporate social responsibility” came into common use in the late 1960s and early 1970s after many multinational corporations formed the term to describe any group that is impacted by a company’s activities. Annual CSR reports are now published, using a framework such as GRI to increase awareness and transparency around CSR and sustainability progress.and the communities in which the company operates, when addressing issues of social and environmental impact.

Policy makers use inventories to develop strategies and policies for emissions reductions and to track the progress of those policies. And, regulatory agencies and corporations rely on inventories to establish compliance records with allowable emission rates. Businesses, the public, and other interest groups use inventories to better understand the sources and trends in emissions.

PPAs are commonly used in public/private partnerships to help finance renewable energy projects. The private developer takes advantage of tax credits and other financial incentives to develop the infrastructure to generate power, while the public partner (typically a municipality) agrees to purchase the power from the developer at a given price for a certain number of years. The PPA helps the developer secure financing for the project by demonstrating to the lender that the generated power will be purchased at a predetermined rate.

It overlays the electricity distribution grid with an information and net metering system. Such a modernized electricity network is being promoted by many governments as a way of addressing energy independence, global warming and emergency resilience issues. Smart meters may be part of a smart grid, but alone do not constitute a smart grid.

Smart Meter: A smart meter, according to regulatory authorities, is an advanced meter (usually an electrical meter) that records consumption in intervals of an hour or less and communicates that information at least daily via some communications network back to the utility for monitoring and billing purposes (telemetering). Smart meters enable two-way communication between the meter and the central system.

Social Return on Investment (SROI): The SROI concept, essentially a cost-benefit analysis, is used by charities, donors and nonprofit organizations to rate the results of their endeavors with firm evidence of impact and created value. The idea of social return on investment was pioneered in the 1990s by a U.S. venture fund called REDF and has since caught on.

In its broadest usage, SRI refers to proactive practices such as impact investing, shareholder advocacy and community investing. Socially responsible investments encourage corporate practices that promote environmental stewardship, consumer protection, human rights and diversity.

The Brundtland Commission: Formally the World Commission on Environment and Development (WCED), known by the name of its Chair Gro Harlem Brundtland, was convened by the United Nations in 1983. The commission was created to address growing concern “about the accelerating deterioration of the human environment and natural resources and the consequences of that deterioration for economic and social development.” In establishing the commission, the UN General Assembly recognized that environmental problems were global in nature and determined that it was in the common interest of all nations to establish policies for sustainable development.
