Just a reminder - it’s time to increase your rooftop insulation.
Meet the new R-20 rooftop insulation requirements* with at least 3.3 inches of Polyiso.
The required insulation values have increased significantly for U.S. buildings. What hasn’t changed is the fact that Polyiso is the most cost-effective choice for the R-value you need. Visit polyiso.org.
*ASHRAE 90.1 increases the minimum required prescriptive R-value to R-20 for commercial buildings in zones 2 thru 8.
The Snake in the Garden
By Mychele Lord
Eddie manages a 1 million-square-foot facility that houses almost 4,000 workers. He called this week about a 6-foot snake that had taken residence in the garden at the main building’s front entrance. The snake enjoys sunning near the park benches, where the employees sit to have lunch and enjoy the beautiful, native landscape and pond. Even though the snake isn’t poisonous, he was still causing some near heart attacks. As we are taking the project through LEED® certification, Eddie called to ask, “What is the green thing to do about the snake?”
In the LEED for Existing Buildings: Operations & Maintenance (LEED-EB O&M) rating system, the Sustainable Sites Credit 3 (SSCR3) calls for exterior Integrated Pest Management, among other things. The credit is worth 1 point, and its intent is to preserve ecological integrity, enhance natural diversity, and protect wildlife while supporting high-performance building operations and integration into the surrounding landscape.
So, what is Integrated Pest Management (IPM) and how is this green pest management different than traditional pest management? IPM is an effective and environmentally sensitive approach to pest management that relies on a combination of common-sense practices. IPM programs use current, comprehensive information on the life-cycles of pests and their interaction with the environment. This information, in combination with available pest-control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment.
Effective IPM will include:
Some pesticides are, by nature, less risky. For example, many biological pesticides derived from natural materials (animals, plants, bacteria, and certain minerals) pose a lower risk. Canola oil and baking soda have pesticide applications and are considered biopesticides. Other plant-derived pesticides (such as nicotine), however, can be quite toxic. Biopesticides include naturally occurring substances that control pests (biochemical pesticides), micro-organisms that control pests (microbial pesticides), and pesticidal substances produced by plants containing added genetic material plant-incorporated protectants (PIPs).
An Integrated Pest Management plan (vs. a traditional pest management plan) calls for the most effective, lowest-risk, least-toxic pesticide. This will vary according to target species. Some examples are outlined in Table 1 (below).
Effective IPM will use services rather than materials to address pest species. For example, consider hand weeding, adding ladybugs, or pruning to reduce the introduction of pest species, instead of using chemicals to eliminate them. If the management plan uses plants and beneficial organisms effectively, pesticide services can be provided, for free, by nature.
The snake mentioned earlier is, no doubt, free from nature and acting as a pesticide. Removing the snake will create an opening in the garden’s ecosystem. Something will fill that opening, and it may be more or less desirable than the current snake. The garden snake, however, is being relocated to the retention pond by popular vote.
