Build Operate and Transfer Projects


Travel and Mobility Services, Energy Efficiency and Water Conservation
The Concept a program anchored in communities with a history as hub cities, hence a reliance on connections and collaborations within and among regions, resulting in a national trading platform with economies of scale utilizing historic trade routes and state of the art products and services to the benefit of community commuters, residents and visitors.
The Objective achieve economies of scale pricing in selected communities around the US in the areas of travel, destination management, transit, energy efficiency and water conservation.
Ways and Means a build operate and transfer project, unique to each community but connecting participating towns via customer sharing, transit programs, energy management and similar measures.
Participants a team of product and services providers who provide know-how and resources to jump-start projects in collaboration with local partners.
The BOT is established for a set duration, renewable - with transfer to local partners, inclusive of training for local individuals, existing businesses, local government and nonprofits, where applicable.
Client Targets: US and International Vacationers, Business Travelers and Commuters
Connecting major air and rail metro hubs with micropolitan communities via
Intercity Multi modal and Local Micro Transit hub and spoke services to
Leverage travel client relationships and engage local product and service providers in:

travel   transportation   energy efficiency   water conservation and manufacturing services
Creating Local Virtual Hotels Increasing Productivity and Improving Customer Service.

Energy Efficiency in Self-Reliant Communities



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 inter-operable, scaleable, 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.

A turn-key solution that reduces installation and maintenance costs. In addition, it is a scaleable and broadly inter-operable 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.
 Tests Demonstrate Energy Savings of 10% for HVAC 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.

CHP Combined Heat and Power FAQs



Combined Heat and Power: Frequently Asked Questions FAQs

What is combined heat and power (CHP)?  An efficient and clean approach to generating electric power and useful thermal energy from a single fuel source. CHP is used either to replace or supplement conventional separate heat and power (SHP). Instead of purchasing electricity from the local utility and burning fuel in an on-site furnace or boiler to produce thermal energy, an industrial or commercial facility can use CHP to provide both energy services in one energy-efficient step.


How Does CHP Work?
o   CHP involves the recovery of otherwise-wasted thermal energy to produce useful thermal energy or electricity, configured either as a topping or bottoming cycle.
o   In a typical topping cycle system, fuel is combusted in a prime mover such as a gas turbine or reciprocating engine to generate electricity. Energy normally lost in the prime mover’s hot exhaust and cooling systems is instead recovered to provide heat for industrial processes, hot water, or for space heating, cooling, and dehumidification.
o   In a bottoming cycle system, also referred to as “waste heat recovery,” fuel is combusted to provide thermal input to a furnace or other industrial process and heat rejected from the process is then used for electricity production.

Why is CHP more efficient than conventional electricity generation? CHP 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 higher efficiency comes from recovering the heat normally lost in power generation or industrial processes to provide heating or cooling on site, or to generate additional electricity. 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.

Is CHP widely used in the United States?
·         The existing 82 GW of CHP capacity at almost 3,600 facilities represents 8 percent of current U.S. generating capacity and 12 percent of total electricity generated.
·         CHP is used in every state, and is primarily found in areas with high concentrations of industrial and commercial activity, high electricity prices, and policies favorable to CHP.

What kinds of facilities use CHP?  
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.
 

What are the benefits of CHP for the energy user?
Ø  CHP reduces energy costs for the user.
Ø  CHP reduces the risk of electric grid disruptions and enhances energy reliability for the user. This is particularly useful for hospitals, research institutions, or industrial facilities where electric power outages are particularly disruptive and costly.
Ø  CHP provides predictability in the face of uncertain electricity prices.

What are the benefits of CHP for Your Community?
o   CHP reduces emissions of GHGs and other air pollutants by as much as 40 percent or more.
o   CHP consumes essentially zero water resources in generating electricity (a typical coal fired power plant consumes 0.2 to 0.6 gallons of water per kWh).
o   CHP offers a low-cost approach to adding new electricity generation capacity.
o   On-site electric generation reduces grid congestion and improves the reliability of the electricity distribution system.
o   CHP defers the need for investments in new central generating plants, transmission and distribution infrastructure, helping to minimize increases in electricity costs.
o   CHP uses highly-skilled local labor and technology.
