Look for
<label for="email"><?php _e( 'Account Email', 'buddypress' ); ?></lable>
<input type="text" name="email" id="email" value="<?php echo bp_get_displayed_user_email(); ?>" class="settings-input" />
And add the following to the beginning and end
<!-- <label for="email"><?php _e( 'Account Email', 'buddypress' ); ?></label>
<input type="text" name="email" id="email" value="<?php echo bp_get_displayed_user_email(); ?>" class="settings-input" /> //-->
