Improving Institutional Access to Financing Incentives for Energy
Improving Institutional Access to Financing Incentives for Energy Demand Reductions Masters Project: Final Report April 2016 Sponsor Agency: The Ecology Center (Ann Arbor, MI) Student Team: Brian La Shier, Junhong Liang, Chayatach Pasawongse, Gianna Petito, & Whitney Smith Faculty Advisors: Paul Mohai PhD. & Tony Reames PhD. ACKNOWLEDGEMENTS We would like to thank our clients Alexis Blizman and Katy Adams from the Ecology Center. We greatly appreciate their initial efforts in conceptualizing and proposing the project idea, and providing feedback throughout the duration of the project. We would also like to thank our advisors Dr. Paul Mohai and Dr. Tony Reames for providing their expertise, guidance, and support. This Master's Project report submitted in partial fulfillment of the OPUS requirements for the degree of Master of Science, Natural Resources and Environment, University of Michigan. ABSTRACT We developed this project in response to a growing locallevel demand for information and guidance on accessing local, state, and federal energy financing programs. Knowledge regarding these programs is currently scattered across independent websites and agencies, making it difficult for a lay user to identify available options for funding energy efficiency efforts. We collaborated with The Ecology Center, an Ann Arbor nonprofit, to develop an informationbased tool that would provide tailored recommendations to small businesses and organizations in need of financing to meet their energy efficiency aspirations. The tool was developed for use by The Ecology Center along with an implementation plan to strengthen their outreach to local stakeholders and assist their efforts in reducing Michigan’s energy consumption. We researched and analyzed existing clean energy and energy efficiency policies and financing opportunities available from local, state, federal, and utility entities for institutions in the educational, medical, religious, and multifamily housing sectors. -
Energy and Buildings
Joint Research Centre The European Commission’s in-house science service Energy and Buildings Renewable Energies and Energy Efficiency Energy consumption About 37% of final energy consumption is taken by the building sector (households and services). A gradual shift over the last five years is observed from fossil fuels to renewable energy sources, such as solar energy, wind power and bio-energy. By means of Directives, Recommendations and Regulations the European Commission is giving direction to the future of sustainable energy use and supporting the low carbon energy policy. Energy performance of buildings and efficient energy end-use are the important topics of interest. European standardisation facilitates exchange of goods, information and services to ensure a competition in a single The Energy Performance of Buildings Directive (EPBD 2010/31/EU) concerns the European market. residential and the tertiary sector (offices, public buildings, etc.). Member states must apply minimum requirements as regards the energy performance of new and existing buildings. A common calculation methodology should include all the aspects which determine the final and primary energy consumption of the building. This integrated approach should take into account aspects such as heating and cooling installations, lighting, the position and orientation of the building, heat recovery and the application of renewable energy. The member states are responsible for setting the minimum standards for buildings that are calculated on the basis of the above methodology. The philosophy that supports the reduction of energy consumption in buildings is presented in three priority steps: 1. Energy saving (improve insulation), 2. Increase energy efficiency (building installations), Contact: 3. -
Energy Efficiency in OECD Countries: a DEA Approach
energies Article Energy Efficiency in OECD Countries: A DEA Approach Filip Fidanoski 1,*, Kiril Simeonovski 2 and Violeta Cvetkoska 2 1 School of Economics, UNSW Business School, University of New South Wales, Sydney 2052, Australia 2 Faculty of Economics, Ss. Cyril and Methodius University in Skopje, Skopje 1000, Macedonia; [email protected] (K.S.); [email protected] (V.C.) * Correspondence: f.fi[email protected]; Tel.: +61-466-337-561 Abstract: This paper deals with energy efficiency examined through an integrated model that links energy with environment, technology, and urbanisation as related areas. Our main goal is to discover how efficiently developed countries use primary energy and electricity (secondary energy). We additionally want to find out how the inclusion of environmental care and renewable energy capacity affects efficiency. For that purpose, we set up an output-oriented BCC data envelopment analysis that employs a set of input variables with non-negative values to calculate the efficiency scores on minimising energy use and losses as well as environmental emissions for a sample of 30 OECD member states during the period from 2001 to 2018. We develop a couple of baseline models in which we find that countries have mean inefficiency margins of 16.1% for primary energy and from 10.8 to 13.5% for electricity. The results from the extended models show that taking care about environment does not affect efficiency in general, while the reliance on energy produced from renewable sources does slightly reduce it.

Energy Conservation Action Plan
2/2/12 Energy Conservation Action Plan Energy conservation is undertaken for a variety of reasons which includes utility cost containment and reduction of the carbon footprint. Incumbent upon all of us is the preservation of resources to perpetuate a quality life style. A holistic approach to conservation is articulated in this plan which outlines action items for an energy conservation program. This energy conservation plan is offered to discuss steps taken, work practices in place, new strategies, and energy conservation policies. At Creighton University, as is the case for most colleges and universities, it is recognized that deferred maintenance on buildings exists and as such, so does the inefficiency of operation. Advancing programs that reduce deferred maintenance will not be specifically addressed in this plan. A variety of action items to enhance energy conservation are offered in this plan to draw attention to a variety of tasks and opportunities that can be pursued. Action Item: A) Implement an Energy Conservation Policy: An energy conservation policy is needed to document the goals of the University in establishing recognition of energy savings. The energy conservation policy includes: Creating guidelines for proper management of our energy resources; (e.g. water, natural gas, and the energy products of steam, chilled water, and electricity). Controlling the waste of natural resources. Maintaining the most comfortable and safest environmental conditions in university buildings at the lowest cost. Creating an outline to be used for educating faculty, staff, students and guests of the University in the day to day practice of energy conservation. An updated but unapproved policy is attached for further discussion and consideration. -

This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. Two types of methods have been considered, methods of analysing and projecting the dynamics of future technology change and methods of evaluating policy instruments effecting technology change, i.e. market transformation programmes. Two methods are focused on analysing the dynamics of future technology change; vintage models and experience curves. Vintage models, which allow for complex analysis of annual streams of energy and technological investments, are applied to the analysis of the time dynamics of electricity demand for lighting and air-distribution in Sweden. -

sustainability Article Exergetic Aspects of Hydrogen Energy Systems—The Case Study of a Fuel Cell Bus Evanthia A. Nanaki * and Christopher J. Koroneos Department of Mechanical Engineering, University of Western Macedonia, Bakola and Salviera, Kozani 50100, Greece; [email protected] * Correspondence: [email protected] Academic Editor: Arnulf Jäger-Waldau Received: 1 October 2016; Accepted: 10 February 2017; Published: 15 February 2017 Abstract: Electrifying transportation is a promising approach to alleviate climate change issues arising from increased emissions. This study examines a system for the production of hydrogen using renewable energy sources as well as its use in buses. The electricity requirements for the production of hydrogen through the electrolysis of water, are covered by renewable energy sources. Fuel cells are being used to utilize hydrogen to power the bus. Exergy analysis for the system is carried out. Based on a steady-state model of the processes, exergy efficiencies are calculated for all subsystems. The subsystems with the highest proportion of irreversibility are identified and compared. It is shown that PV panel has exergetic efficiency of 12.74%, wind turbine of 45%, electrolysis of 67%, and fuel cells of 40%. Keywords: exergy analysis; fuel cell bus; hydrogen; sustainable transportation 1. Introduction Road transport energy supply mainly depends on fossil fuels, the use of which is responsible for climate change emissions, such as CO2, SO2, NOx, and other particulate matters. To be more specific, the transportation sector accounts for approximately one-fifth of global primary energy use and one quarter of all energy relates carbon dioxide (CO2) emissions with nearly half of those emissions originating from passenger vehicles [1].
