CDH Energy Overview

We provide energy system and technology analysis.

We use both field monitoring and energy simulation skills to assess technologies, verify savings, assess markets, or determine application feasibility. Applications include: building system design options analysis, energy savings project feasibility studies, product assessment and technology research and demonstration.

CDH Energy Corp. was founded in 1994 to provide energy analysis services for utilities, government labs, research organizations, building owners, and industrial clients.

May 2012 CDH, on behalf of Energy Efficient Buildings (EEB) HUB, complete installation of a comprehensive monitoring of a building in Philadelphia Naval Yard

CDH Energy Corp. is completing installation of a comprehensive monitoring system of a building in the Philadelphia Naval Yard. This project is funded by the Department of Energy, through Pennsylvania State University. The building being monitored is one of the most heavily instrumented buildings in the world; there are over 1550 data points installed in the various building systems. This extensive monitoring of energy use is being done to aid in improving energy modeling software and to document energy efficiency improvements in the building. The extensive instrumentation will result in data that will illustrate the impact of retrofits and repairs that are made over the next few months. Every aspect of building facility systems are being monitored including HVAC, domestic hot water (DHW), lighting and indoor air quality. The project will help to improve the way building facilities are managed. Data is being collected at 1 minute intervals and is available in real time, to authorized users.

December 2011 - CDH and ARIES Start New BUILDING AMERICA PROJECT to Develop Field Test Protocol for Oil-Heated Homes

CDH Energy Corp has begun a project to develop a test protocol to verify energy savings in retrofitted homes that use oil heat. This protocol will support the US Department of Energy's (DOE) Better Buildings Program. The research project will use the detailed measurements of oil use from several homes to verify that low cost field measurement approaches can accurately predict the fuel consumption of oil-fired furnaces and boilers. The DOE Building America research program seeks to develop integrated energy systems that substantially reduce annual energy consumption while improving building comfort, safety, performance and durability, all in a cost effective manner. CDH Energy is a member of the ARIES Collaborative (Advanced Residential Integrated Energy Solutions); one of several research teams that are part of the Building America Progarm. ARIES team is led by The Levy Partnership in New York and also includes The Syracuse Center of Excellence in Environmental and Energy Systems, Southern Energy Management, NYSERDA and other organizations. The ARIES Collaborative has worked in the Building America Program since the beginning of 2011.

October 2011 - CDH Completes Final Report for Comparative Roof Testing on Onondaga County Facility

CDH Energy Corp recently completed a field test comparing the energy efficiency and water retention performance of four different "green" roof systems. CDH teamed with Ashley McGraw Architects to complete this research project for Onondaga County. Data loggers and instrumentation were installed in the fall of 2009, to compare the thermal losses from conventional "black" roofs with standard insultation, to better insultated "white" roofs, as well as vegetative "green" roofs. The side-by-side-by-side test was conducted at Jamesville Correctional Facility. Continuous data collection (at 15-minute intervals) started in October 2009, and has continued for the last two years. The results confirmed that a "white" roof surface did reduce heat gains and cooling loads in the summer, but the reduction in heat gains in the winter, spring and fall also increased heat losses. On an annual basis in Syracuse's climate, the "white" roof had no net impact on combined heating and cooling costs. The vegetative roof was shown to have more thermal benefit than expected. The net cost savings were estimated to be $7 per year per 1000 square ft. of roof area. More importantly, the vegetative roof significantly reduced the amount of water draining from the assembly. On average only 20% of measured rainfall on the roof ended up in the storm drain system.
