Butler did it: A green roof comes to the college
Indianapolis-based Eco-Roofs, a producer of environmentally friendly roof systems, has completed a 1,300-sq.-ft. green roof installation atop the four-story, 67-year-old College of Pharmacy and Health Sciences Building on the campus of Butler University in Indianapolis.
This is the first green roof undertaking for the University and was installed entirely by an all-volunteer crew of students, faculty and university staff, led by Eco-Roofs’ accredited Green Roof Professional and project coordinator Pat Maloney.
The project was initiated by Butler biology student Sarah Strobl while researching green roofs as a topic for her honors thesis. Strobl led the effort to secure funding from the Student Government Association in order to see the project completed before the end of her senior year. After conducting feasibility studies and other background analysis, Strobl and University officials, including campus engineer Rich Michal, consulted with a number of green roof manufacturers in January 2012 and determined that Eco-Roofs was the only system that could meet all of their needs.
Core to the university’s objectives was that the installation be a learning experience for students and provide ongoing opportunities for scientific study, in addition to being an interactive green space that can be seen and used by university staff and students. One of the key features of the Eco-Roofs system is the ease of installation engineered into the modular system of plant trays.

Crow’s Market Recap — A condensed recap of the market conditions for the major North American softwood lumber and panel products as reported in Crow’s Weekly Market Report.
Lumber: Strong demand allowed SPF mills to raise dimension lumber prices $5 to $10. Low inventory levels prompted buyers to replenish. Wholesalers purchased, sold those volumes and then purchased again, contributing to mill order files extending into the week of May 14. Despite reports of gradual slowing in the Southern Pine lumber market early in the week, demand remained solid enough to keep order files out two weeks and dimension prices rising by double digits. Treaters remained a key force behind price increases. Diminished production levels and solid demand kept upward pressure on dry Coastal species dimension lumber prices. Dry Doug Fir prices experienced price appreciation across all dimensions, while trading levels in green Doug Fir saw an uptick. Inland species lumber producers remained in control of the market for another week, as buyers looked for quick shipments and specified tallies. Most were unsuccessful on both counts. Limited selections at mills forced buyers to compromise on their needs or look to secondaries for coverage. Radiata Pine Shop offerings were limited, as was Mldg&Btr. Prices were firm. Market conditions for Ponderosa Pine Moulding and Shop were little changed. According to buyers, 5/4 #3 Shop was readily available, but 6/4 was more difficult to find. Lack of availability and moderate demand combined to keep Ponderosa Pine Selects and Commons on firm ground, for the most part. Eastern White Pine producers continued to concentrate on shipment schedules. Prices remained firm. Activity for ESLP remained steady, as exports and three week order files helped producers remain in control. Western Red Cedar producers sold steady volumes, which kept several prices on an upward tilt. Order files often extended into June and even July in some instances.
Panels: Just when it looked like OSB markets were on the verge of collapse, a rally at mid week breathed new life into the market. Driven by strong sales to U.S. destinations, mills were able to extend order files out and firm or raise prices. Most Southern Pine plywood prices remained on firm footing after a week of steady demand. Producers continued to push order files out another week. Volumes sold in the Western Fir plywood market eliminated any early inclination among producers to listen to counters. Producers accepting modest counters firmed prices by late Tuesday and joined other producers in raising them $5 to $10 by the week’s end. The Canadian softwood plywood market remains firm in spite of a quieter pace to sales this week than previous weeks. Order files are out to the week of May 28. Particleboard producers posted another good week of sales, while those MDF producers reporting a slower pace last week often saw buyers come back into the market to replenish.
