Builder Lennar Corp. won praise for its green performance in a report issued Tuesday, but lost points for its limited offerings of sustainable homes. The Miami-based home builder ranked No. 5 among 13 publicly traded homebuilders in a report on the industry’s most environmental and sustainable builders, compiled by Maryland-based Calvert Group with Boston College’s Institute for Responsible Investment. The report ranked the homebuilders in three categories — policy, programs and performance — and used those to compile an overall score. Lennar was No. 7 for policy, No. 7 for programs and No. 3 for performance.
