He holds a B.S. in Forest Engineering from the State University of New York School of Environmental Science and Forestry.


Michael Khazzam

A breathable enclosure is a durable enclosure. In an industry offering a wealth of building materials and processes all designated for the building enclosure it is impossible to apply a one case fits all combination of materials. The purpose of the building enclosure is to keep external elements out of the building, that’s the easy part. Creating a breathable air tight enclosure is the difficult part. Michael Khazzam has over 10 years of experience providing consulting services for new building enclosure design as well as building restoration enclosure re-design. He specializes in analyzing and simulating heat and moisture transfer across building walls and roofs in order to design the enclosure. Choosing a building enclosure while satisfying requirements such as building location, height, orientation, local climate, use and codes requires in-depth analyses. Michael has the design and construction management experience necessary to transform tired building envelopes into advanced modern enclosures that actually work. Michael holds a bachelor’s degree in Building Engineering and is a LEED Accredited Professional.


Joaquin Crespo

Joaquin Crespo is a Senior Mechanical Engineer with over 30 years experience in Heat Ventilation and Air Conditioning (HVAC) system design. Mr. Crespo has been developing mechanical systems for commercial, residential, institutional and industrial facilities in the tri-state area for few well recognized consultant engineering firms. His expertise encompass all aspects of HVAC design; conceptual design lay-outs, cooling and heating heat (gain and loss) calculations, energy consumption’s calculations, operational cost analysis, selection of equipment, develop construction documents (REVIT & ACAD drawings and specifications), operational & maintenance manuals and constructions administration. Some of his projects had required LEED and commissioning certifications. Mr. Crespo is a truly team player with excellent communications skills.
