Overview
Mission
The purpose and mission of the Collaborative is to create and distribute window preservation standards that include a catalog of proven methods used to maintain, repair and weatherize older and historic windows, including well-researched weatherization and energy conservation information.
What it reported doing in 2025
Window Preservation Standards Summit (Biennial Educational Program) was held in October of 2025. Total summit expenses were approximately $41,600 administered through the Window Preservation Alliance (WPA), a seperate nonprofit and collaborative partner. WPSC reported only expenses paid directly by WPSC. 83 attendees at the event
Operating model
- Revenue model
- Other-operating. 76% of the money available for current operations came from other operating revenue.
- Distribution model
- Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.
The verdict
SUPPORTED - The filed numbers largely add up and revenue comfortably covers expenses. A relatively small share of available resources goes toward mission work and reported officer compensation is a large share of total spending, which may reflect staffing concentration.
