years of experience with energy conservation while managing projects at universities, government buildings, and privately owned buildings. His presentation provided an introduction to the 3 R’s of Energy Management namely, Resiliency, Reliability & Risk Management. He further described how the 3R’s can be optimized in projects pertaining to co-generation, microgrids, renewables, energy storage & procurement. While talking about the potential of System Based Solutions such as microgrids, renewables, and storage, in increasing system reliability, he emphasized on their careful implementation to be supported by a technical and financial feasibility analysis.
The National Capital Chapter of the Association of Energy Engineers (AEE) organized a Panel Discussion on Emerging Energy Technologies. This luncheon event, sponsored by Edison Energy and Eneractive Solutions, covered a wide range of topics presented by an array of four industry experts at the George Washington University campus in Washington D.C. AEE-NCC President John Lord welcomed the attendees with an overview and invitation to the chapter’s upcoming events. The Panel members were then introduced by Kevin Chisholm, AEE member and Principal of Mid-Atlantic Energy Services. Opening the panel Doug Millar (Regional Vice President Mid-Atlantic, Edison Energy), who has extensive experience in the design and installation of combined heat and power (CHP) projects, described co-generation as an effective way to achieve energy cost savings. He has over 25
With over 30 years of energy engineering experience, Bruce Beddow, Project Director of B2E Consulting Engineers, showed the implementation of innovative technologies such as Geo-Solar Heat Pump Systems in integrated low energy design for buildings. He described the role of Variable Refrigerant Flow (VRF) systems and Energy Recovery Units (ERU’s) in the optimization of Net Zero Ready buildings. Renewable Energy (such as Solar Thermal energy and Geothermal energy) can be combined with Domestic Hot Water and HVAC systems. In the case of ERU’s with Solar Thermal energy, heat from the sun can be used to get hot water, which runs through the coil heating the ventilation air and this air can be controlled through Variable Air Volume (VAV) boxes. When using Geothermal energy in combination with ERUs, Variable Refrigerant Flow (VRF) systems allow for energy optimization. Bruce further compared the designs of conventional and innovative systems in terms of reduction in energy consumption and improvement of indoor air quality. His designs for public school facilities have improved indoor air quality while reducing operating costs. In his analysis for Energy Utilization Index (EUI), he described how the annual energy cost for a building can be lowered with each step of energy recovery.
The panel ended with the final presentation by John Bergman, Consultant and Marketing Director, Havtech and President, John E Bergman LLC. With over 30 years of HVAC experience, John has provided sales and marketing consulting for HVAC manufacturers and sales representatives. He described conventional heat recovery chillers to be less efficient and not suitable for retrofit applications due to their large size and complex operation. John further described innovative heat pump technologies (water-to-air and water-to-water heat pumps) that can maximize heat recovery and apply to various settings including systems where simultaneous heating and cooling loads occur. He presented various configurations of modular chillers that can help in efficient use of energy and available floor area while being easy to maintain.
All speakers for the AEE-NCC Panel Discussion provided an overview and practical implementation of their projects utilizing innovative energy efficient technologies and supported their information through case studies. The event sparked interest from a wide range of audience including students, young
January 27th: Emerging Energy Technologies Panel Discussion
The panel discussion was continued by the next speaker, Rajesh Sinha, who is serving as Director-Americas of Thermax, an India based ISO 9000 certified engineering organization offering energy conservation products and services. Rajesh provided a detailed overview of the Vapor Absorption Technology that provides a cost-efficient cooling solution and has a reduced environmental impact compared to the conventional electricity-driven Compression chillers. The unique feature of this technology lies in the usage of water as a refrigerant resulting in a high Coefficient of Performance (COP) ranging from 0.7-1.38 depending upon the temperature of inlet water and type of cycle used. Solar cooling involves usage of heat from the sun to get hot water, which in turn can drive the absorption chillers connected to cooling towers and provide chilled water (44°F). This technology can be customized to suit different types of solar concentrators. The latest range of innovative equipment comprises of Multi-Energy Vapor Absorption Chillers.
