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.
Fall 2011 UPDATE - CDH Continues with NYS CHP MONITORING
CDH Energy Corp continues working with NYSERDA on the web-based DG/CHP (Distributed Generation/Combined Heat and Power) data system for NYSERDA's DG/CHP demonstration project. This project, begun in 2005, has expanded currently to 104 sites in New York State, ranging from educational facilities and rehabilitation centers, to office buildings and manufacturing plants. Data and information from the demonstration sites are available on the NSERDA CHP website: www.chp.nyserda.org. DG/CHP systems offer the potential to reduce operating ocsts for end users, as well as improved the reliability of electric distribution and transmission. Increasing numbers of sites are investing in this technology because of the promising savings in energy and cost.

CDH Energy Corp was recently awarded research project 1449-TRP by the American Society of Heating, Refrigeration & Air Conditioning Engineers (ASHRAE). The project will use building simulation to complete an energy efficiency and cost assessment of humidity control options for residential buildings. CDH teamed up with Building Science Corporation on a project to investigate the advantages and disadvantages of various technology options and HVAC design approaches that may be extensively applied in humid climates and other circumstances where latent loads comprise a larger-than-typical portion of the total cooling requirement.

"HomePIC" Project Begins. A team lead by CDH Energy has been awarded a project that seeks to demonstrate that highly energy efficient design practices can be applied in moderately-priced homes. The Home Performance Improvement Challenge (HomePIC) team, which also includes the Syracuse Center for Excellence (COE) in Environmental and Energy Systems, Northeast Green Building Consulting, Camroden Associates, and Syracuse University BEESL, has been awarded a contract from the New York State Energy Research and Development Authority (NYSERDA) to work with builders to incorporate energy efficient design and construction practices into their homes. The goal is to achieve Home Energy Rating System (HERS) Scores of 93. The project was described in a February 21 newspaper article as well as a press release from the Syracuse COE.

CDH Energy recently published a report on Mitigating the Impacts of Uncontrolled Air Flows (UAFs) on Indoor Air Quality and Energy in Commercial Buildings. Partners on this project included the Syracuse University STAR Center for Environmental Quality Systems and Florida Solar Energy Center (FSEC).

CDH Energy and the Florida Solar Energy Center (FSEC) recently completed a report for the US Department of Energy (DOE) that summarizes a multi-year research project to understand the dehumidification performance of air conditioners at part load. The report documents lab and field test results as well as new engineering models that were developed to predict part load latent degradation. To view/download the PDF file, click here.

CDH Energy has been working with NYSERDA, EEA and Summit Solutions on the NYSERDA DG-CHP Integrated Data System. The Project has now gone live at chp.nyserda.org
Electricity and Natural Gas Trends for New York State - October 2005
For Niagara Mohawk commercial customers, the rising cost of oil is not only driving up the cost of natural gas (with a projected cost over $1.20/therm for natural gas supply), it is also causing an increase in the cost of electricity. Historically, the market supply charge has been offset by a delivery adjustment, which has kept peaks in the net cost of electricity subdued. Since January 30, 2005, the delivery adjustment to customers under the Niagara Mohawk SC3 tariff has been zero - indicating that commercial customers are now paying the prevailing market rates for electricity purchases. This has resulted in electricity supply charges increasing from near 6 cents/kWh in January 2005 to over 12 cents/kWh in October 2005.
The impact has been less severe for small commercial and residential customers.
