At Green Home Logic (GHL), we are well aware that no two homes are alike. Furthermore, we understand that no two clients are alike. Therefore, we deal with each home and client on a case-by-case basis to provide a custom tailored package is developed to ensure the highest level of cost savings and comfort are achieved.


GHL is a BPI Accredited Home Performance Contractor, specializing in the installation of Energy Saving Improvements. We start by evaluating each home to determine its strengths and weaknesses in terms of energy efficiency and overall comfort. We then estimate the amount and types of material that would ultimately result in the highest level of energy reduction and overall comfort within the home. Afterwards, we advise each client and explain each program/incentive that he/she is eligible for. GHL professionals are well versed NY State programs and incentives that currently exist and although this is the most complicated part of the process, we believe that it is by far the most important. Lastly, GHL will deliver the highest standard of project management and installation of energy saving measures and equipment. Although we have the ability to make a home Net Zero with the right budget, we always strive to get the most out of your budget.


On a daily basis, Utility Providers and NY state agencies are revising, improving and developing new incentive-based programs for residential and commercial properties. Navigating and packaging these incentives can be overwhelming and professional assistance may be required simply to get a project off the ground. At GHL, we make it a priority to keep up with revisions to existing incentive programs in order to ensure that our clients achieve the optimal incentive and loan packages.
