Mass. glazing requirements for school buildings impede energy efficiency #green

It appears that Massachusetts now requires low solar heat gain (below 0.4) for windows in school buildings constructed with state aid: http://www.massschoolbuildings.org/sites/default/files/edit-contentfile/... The SGHC must be no higher than 0.4, according to page 186 of this document. Has anyone attempted to quantify that savings you would gain by planting trees on the south side of the building and using high solar-heat-gain windows instead? Since a school is barely used from june 20 to august 30, it might not even be necessary to run the AC much, giving another reason why high solar heat gain windows could make sense.
