In a ranking published November 27th, Partners in Building was listed as the sixth largest green builder in Houston by the Houston Business Journal. To qualify for the list, builders must be GHBA certified as part of the Green Building Initiative, or all homes being built must be environmentally friendly. "By including features like Tech Shield roof decking, Low-E glass windows, and high levels of insulation, we are able to build homes that retain cool air in the summer and warm air in the winter. When homeowners use less electricity to heat and cool their homes, it has a positive effect on the environment" said Elizabeth Phillips, Partners in Building's marketing director. Partners in Building is part of the Environments for Living program, Energy Star, and the GHBA's Green Building Initiative. These programs have different criteria, and they help insure homeowners that the homes they purchase are tested to meet strict guidelines for energy efficiency.
