Indoor "Green Audit." While the Arboretum's efforts to be "more green" indoors have brought on positive change, there is room for improvement. In December of 2008, the Ashkin Group, with the help of Tennant Company, conducted a green audit of Arboretum buildings and provided best practices and steps that can be taken in the short term and long term to improve our sustainability efforts and make the buildings more environmentally friendly.
Energy Audit. Centerpoint Energy conducted a Custom Energy Analysis of the Snyder Building in May 2007 and provided a report showing current natural gas usage and making recommendations for projects that will save energy in the future, The report gives costs and estimates of energy saved for many improvements and also includes payback periods which range from 1 to 12 years.
Irrigation Best Practices. Thanks to a recently completed audit by Irrigation Consultants & Control, the Arboretum will be taking steps to improve its irrigation system further, using the best and most up-to-date methods.
