Saving Energy on Main Street and in Historic Districts
Energy Services Agreements – ESAs – are pay-for-performance, off-balance sheet financing solutions that allows customers to implement energy efficiency projects with zero upfront capital expenditure. As in the case of power purchase agreements – PPAs – equipment is installed, owned and operated by the vendor who sells the saved power to the customer.
ESAs are the Energy Efficiency Equivalent of a Power Purchase Agreement
Energy Service Companies – ESCos – provide designs and implementation solutions for energy savings projects, retrofitting, energy conservation, outsourcing, power generation and supply.
Energy Savings Performance Contracts – ESPCs – accelerate investment in cost effective energy conservation measures without up-front capital costs. ESPCs are partnerships between a property owner/operator and an ESCo which conducts a comprehensive energy audit to identify improvements to save energy, designs and constructs the project as well as arranges the necessary financing.
An ESCO Guarantees the Improvements that Generate Energy Cost Savings
Energy Savings result from lighting upgrades, building automation system and controls. A Flexible Contractual Tool for retailers looking to stabilize utility costs as well as achieve longer term benefits by buying out the contract and take ownership of installed equipment.
ESA Payments are operating expenses designed to be off-balance sheet financing solutions with regular payments similar-to a utility bill.
Outputs Quality and Achievements of Specific Measurable Performance Standards and Requirements
Benefits resulting from the application of ESAs include energy efficiency, water conservation, emissions reduction and streamlined contract funding for energy management projects, through access to private-sector expertise, built-in incentives to provide high-quality equipment, and project commissioning infrastructure improvements. Project management ensures building efficiency and new equipment without upfront capital costs as well as energy and related operation and maintenance cost saving guarantees.
Energy Management Open Source Software for Small and Medium-sized Commercial Buildings
Commercial Buildings account for 20% of total energy consumption in the United States. The larger units use management systems or automation systems BAS to improve comfort and reduce energy costs; however, small and medium sized commercial building, which account for half the sector’s energy usage and 95% building stock, lack cost-effective BAS solutions and the resultant savings.
Property Owners are often Unaware of Energy Waste and BAS Savings Opportunities
Load Types there are three major loads in commercial buildings: HVAC, lighting and plug loads. According to the data from EIA published in 2008, electricity use by HVAC equipment accounts for 30% of the total electricity consumption, lighting loads use 38% and plug loads 6%.
Cost and Interoperability BAS systems need to become much more interoperable, scalable, and easy to deploy by utilizing open architectures, plug-and-play and providing local or remote monitoring. Most systems currently use proprietary architectures requiring building owners and controls designers to purchase devices and controllers from a single vendor instead of optimal products, controls, and services from different vendors.
Turn-key Solutions that reduces installation and maintenance costs. In addition, it is a scalable and broadly interoperable solution with seamless HVAC, lighting, plug load equipment and controller integration from different manufacturers, hence plug-and-play functionality for the many system configurations found in smaller commercial architectures.
System Features Open Source Architecture Cost Effective Interoperability Ease of Deployment Local/Remote Monitoring Manufacturer Friendly Developer Friendly Scalability Plug and Play Secure.
Energy Savings of 10% for HVAC loads and 15% for Lighting Loads
Benefits the system provides small-sized commercial building owners access to flexible, cost-effective building energy management that streamlines operations and optimizes energy usage. Also, the greater interconnection between building systems and a centralized control structure facilitates demand response, providing additional savings and better integration with the electric power grid.
Cogeneration for Your Neighborhood Small Town and Business
Combined Heat and Power involves the recovery of otherwise-wasted thermal energy to produce useful thermal energy or electricity, configured either as a topping or bottoming cycle. It is a form of distributed generation, which is located at or near the energy-consuming facility, whereas conventional generation takes place in large centrally-located power plants. CHP’s inherent higher efficiency and elimination of transmission and distribution losses from the central power plant results in reduced primary energy use and lower greenhouse gas (GHG) emissions.
CHP can be utilized in a variety of applications that have significant electric and thermal loads. Eighty-eight percent of existing CHP capacity is found in industrial applications, providing electricity and steam to energy-intensive industries such as chemicals, paper, refining, food processing, and metals manufacturing. CHP in commercial and institutional applications is currently 12 percent of existing capacity, providing electricity, steam, and hot water to hospitals, schools, university campuses, hotels, nursing homes, office buildings and apartment complexes.
Cogeneration involves the recovery of otherwise-wasted thermal energy to produce useful thermal energy or electricity. Off-grid neighborhoods, small towns and businesses can harness a combination of renewable energy, household composting, wastewater management agricultural and industrial waste-to-resource systems to generate surplus energy that enable self-reliant and resilient neighborhoods.
Communities benefit from new, scalable and mobile technologies that are personalized to meet the unique requirements to achieve a closed loop system utilizing available local resources. Biogas can be used in cogeneration systems for production of heat to be used on site and other requirements. This technology can treat waste from agricultural farms, livestock farms and milk factories as well as produce green energy that can be sold.
District Energy Networks utilize any combination of fossil, recuperative and renewable fuels to create energy and heat that is then distributed from a central system via a pipeline system to business, institutional and private users resulting in functional, economic and ecological advantages.
Financing Alternatives Traditional banking and leasing options are available along with federal, state and local assistance. Also, build, operate and transfer – bot – programs that reduce upfront investment costs.
