Nothing could be more costly than a window or door system that renders fine on a computer screen but fails once it hits the ground. Leaks, thermal deficiencies, violation of codes, structural defects, and acoustical inadequacy – all those consequences result from the failure to have a thorough engineering work performed from the very beginning of the project.
It is precisely this problem that AAWD Inc.’s Design and Engineering service aims at solving.
Being a comprehensive commercial fenestration contractor operating in the tri-state area since 1994, American Architectural Window & Door provides a broad array of services related to the installation and replacement of windows and doors in residential complexes, commercial facilities, restoration and adaptive use projects, and building renovations in New Jersey, New York, and Connecticut.
The Design and Engineering service is the first step in AAWD Inc.’s workflow. It is here that the product is selected properly, compliance with codes is checked, specifications for custom fabrication are established, and specific parameters of your building are taken into account in order to provide you with the appropriate fenestration system.
On this page, we provide an overview of the Design and Engineering service provided by AAWD Inc., explain its importance, describe the procedure involved, and give reasons why property owners and managers in the tri-state area choose AAWD Inc. to perform this task.
What Is Window and Door Design and Engineering?
Fenestration design and engineering is the process of determining which fenestration systems are suitable for a specific building project, how those products need to be specified, their performance in the conditions of that specific building project, and finally the manufacturing, installation, and maintenance of those fenestration systems.
It is an entirely separate activity compared to window selection from a catalog. The catalog selection will tell you the capabilities of the selected product in optimal conditions. Fenestration design and engineering will determine if that product is suitable for the specific project taking into account building height, building orientation, wind load, thermal zoning, fire-rating requirements, occupancy classification, and existing structure conditions.
Design and engineering of fenestration is especially important for the multi-family and commercial buildings in the tri-state region. There are multiple code requirements (energy codes, egress requirements, fire-rating requirements, accessibility requirements, and in some jurisdictions even landmark preservation requirements) which have to be considered before any window can be ordered or installed.
Why Fenestration Design and Engineering Are Even More Important In 2026
There is an increasing number of requirements for commercial and multifamily window and door systems in 2026 compared to any other time in the history of the industry. Fenestration systems in 2026 will need to meet the following requirements:
- Tightening Energy Codes
IECC 2021 adopted in New Jersey and New York sets new performance standards for fenestration systems which are more difficult than in previous code cycles. Maximum U-factors and SHGC limits for commercial and residential applications have changed. Compliance needs to be proved not only at the center-of-glass but also at the assembly level.
This means that the frame system, thermal break, and installation details affect the final number used for compliance. This cannot be done using a catalog selection but rather needs fenestration engineering.
- Adaptive Reuse/Building Conversion
Adaptive reuse/office-to-apartment conversion of warehouses, office buildings and many other types of buildings is a huge part of the current NJ/NY construction market. These projects put unique fenestration requirements on the buildings because the building envelope was originally designed for a different occupancy type with different codes.
AAWD is very familiar with the challenges of fenestration for adaptive reuse and has years of experience with it – fenestration compliance for egress in converted buildings, fenestration upgrade for thermal performance of legacy curtain walls, waterproofing between new windows and existing framing.
- Historic Preservation
Both NJ and NY have a significant number of historic buildings which require special consideration when doing fenestration work. Replacement/upgrading of windows in these buildings has to follow not only current energy codes and egress but also State Historic Preservation Office (SHPO) guidelines.
Why AAWD’s Track Record Matters For Your Design and Engineering Service Project
AAWD Inc. was founded in 1994 by John Zoetjes, initially as a replacement window company. In over 30 years, the company evolved into a comprehensive commercial fenestration contractor and building products provider and was named by NJBIZ as the 29th fastest-growing company in New Jersey.
This isn’t just marketing information – it’s proof that, in a construction market renowned for being extremely challenging and tightly regulated, AAWD Inc. successfully delivered project after project by fulfilling highly complicated technical specifications in occupied buildings, historically designated structures, and high-rises where there is simply no room for mistakes.
