With energy and emission reductions at the forefront of NYC’s concern, Jon and his team perform energy audits and make recommendations for upgrades to conserve energy so buildings can better prepare for the upcoming Local Law 87 & 97 deadlines. This could include his team performing cooling plant upgrades, heating plant upgrades / fuel conversions and building-wide lighting retrofits. Throughout the COVID19 pandemic, Jon and his team also worked to ensure HVAC systems in buildings and building amenity spaces throughout NYC met all the necessary safety standards to resume operation.

Additionally, with the heightened concerns revolving around gas piping distribution systems, Jon has been working closely with the NYC Buildings department as well as industry leading licensed master plumbers to strategize ways to perform proactive gas piping repairs and/or upgrades to prevent sudden and unexpected building wide gas shutdowns following the mandatory LL 152 inspections.
