Book Cover Design Brief
I work for an HVAC trade association that publishes technical manuals. We have a series of books that need new covers since there have been many changes.
I'd like the books to have a similar style to each other (like the current Manual S and D, see below). Here is a listing of all our current manuals https://www.acca.org/standards/technical-manuals. We plan on updating more in the future, like H, , N and ZR. So I'd like a design that we can continue on.
The 3 covers I need are
1. Manual J Residential Load Calculation
https://www.acca.org/standards/technical-manuals/manual-j
2. Manual D® - Residential Duct Systems
https://www.acca.org/standards/technical-manuals/manual-d
3. Manual S® - Residential Equipment Selection
https://www.acca.org/standards/technical-manuals/manual-s
I included our logos and style guide as a resource. But I'm open to all images and colors. The audience is primarily engineers, software developers, code officials and HVAC technicians. These 3 manuals are aimed at residential (single-family homes/townhomes) in the United States.
