JOB NO.: A0035-0215-221 <br />SUBJECT: SEISMIC LOADS <br />PROJECT: James Minnis Residence <br />CHECK INCREASE IN OVERALL SEISMIC LOADS <br />10.2 psf <br />2.3 psf <br />14% <br />10.5 psf <br />3.1% <br />Conservatively neglecting the weight of existing wall materials, the installation of the solar panels represents an <br />increase in the total weight (and resulting seismic load) of 3.1%. Because the increase is less than 10%, this <br />addition meets the requirements of the exception in Section 503.4 of the 2019 CEBC. Thus the existing structure <br />is permitted to remain unaltered. <br />Addt'l Seismic Weight <br />Estimated Roof Dead Load <br />Solar Dead Load <br />% Roof Covered <br />Equiv.
