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 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.
Bemoss is a turn-key solution 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.
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.

Transit Solutions and Location Efficient Communities



Public Transport Walking Biking and Land Use Planning
Transportation Infrastructure is the backbone of our communities. A reduced dependence on the automobile enables land use planning that reduces household transportation costs and frees up space for transit, pedestrian, and bike systems as well as rationalizing the use of existing infrastructure.
Transit Oriented Development transportation is the second-highest household expense; access to transit enhances access to the workplace and schools. TOD not only benefits new and existing residents, but also businesses, transit agencies, local governments, merchants, and developers.
Greenhouse Gas Emissions are lower in Dense Urban Areas than the Suburbs
Location Efficiency is defined as communities with walkable streets, access to transit, proximity to jobs, mixed land uses, and concentrations of retail and services achievable with policies like free transit passes and car-sharing as well as planning tools that identify land parcels under development and calculate the benefits of locating in a walkable community near existing transit facilities, allowing
Developers and Local Public Officials to identify traffic reduction strategies by location, design and the amount of parking needed in support of smart, well-located developments during the development review process as well as engage residents and contribute to future neighborhood planning.
Walking and Biking nearly 20% of auto-related fatalities involve pedestrians and bicyclists. Walking and bicycling can be made safer at dangerous intersections, streets, sidewalks as well as for wheelchair users by utilizing existing planning tools.
Land Use Planning decisions help determine ways to reduce housing and other costs for families living in places with good public transportation and ameliorate costly and time consuming commutes.
