Taitem has led over 20 energy research projects, and its findings have been published nationally in peer-reviewed journals. 

Cold Climate Packaged Heat Pump Solution
New York Power Authority Report, February 2022.
The New York City Housing Authority (NYCHA), New York Power Authority (NYPA), and New York State Energy Research and Development Authority (NYSERDA) launched an industry competition directed at heating and cooling equipment manufacturers to develop a new Cold Climate Packaged Heat Pump to better serve the needs of existing multifamily buildings. Taitem developed the specifications that manufacturers will use to develop the envisioned product which will help drive down cost and reduce disruption during installation.

Preventing Refrigerant Leaks in Heat Pump Systems

ASHRAE Journal, January 2021.

Heat pumps are viewed as the primary path to the electrification required to reduce and eliminate fossil fuels and associated carbon emissions in building energy systems. However, most heat pumps used in the US today contain R-410A, which is itself a relatively potent greenhouse gas. Preventing refrigerant leaks is therefore a priority. This article examines the issue and suggests best practices to prevent refrigerant leaks.

Air to Water Heat Pump Demonstration
New York State Energy Research and Development Authority (NYSERDA) Report, June 2019.
In partnership with NYSERDA, Taitem Engineering completed a demonstration project focused on the practical application of air-to-water heat pumps for heating use in residential buildings. Throughout the project phases, Taitem identified market barriers to broader adoption of air-to-water heat pumps which are outlined in this report. Design strategies were developed to circumvent some of the barriers to adoption of this technology, although barriers related to cost and installation contractors remain.

Industrializing Deep Energy Retrofits, Spring 2019.
Not all retrofits can be accomplished in one go, as the PHI recognized when it created a certification for phased retrofits, or EnerPHit projects. Deep energy retrofits of existing structures are an absolute must for meeting any reasonable carbon emission reduction goals, but cost-effective retrofits are challenging, to say the least.

Energiesprong: A Dutch Approach to Deep Energy Retrofits and Its Applicability to the New York Market
New York State Energy Research and Development Authority (NYSERDA) Report, March 2018.
In partnership with NYSERDA, Taitem Engineering led a fact-finding mission to the Netherlands to conduct an assessment of their EnergieSprong program which was created to lower energy use in affordable housing. Net energy use is successfully being eliminated by reducing energy use, converting all energy uses to electricity (eliminating fossil fuels), and producing this electricity on-site with solar energy. The approach appears to be transferable to the New York State market. The findings from this report laid the foundation for NYSERDA's RetrofitNY program.

On-site Energy Manager (OsEM) Pilot Program
The latest in comprehensive energy managementRead two impactful case studies from Taitem’s work as a NYSERDA On-Site Energy Manager (OsEM) about two industrial facilities exceeding their energy savings goals. This program offers a 75 percent cost-share for industrial, commercial, and multifamily buildings to work with Taitem for one year as a dedicated on-site energy manager. Taitem Senior Energy Analysts served as OsEMs for two manufacturing facilities:
Corning Diesel Plant, Corning, NY>
Gutchess Lumber, Cortland, NY>
