Big Green Zero Energy Due Diligence(TM) is taking commercial energy audits to the next level by translating engineering calculations into financial options. Energy Due Diligence(TM) considers a wide range of business risks as well as cost recovery opportunities. A Big Green Zero property is about as "green" (and financially viable) as a commercial or industrial property can be. In addition to providing the Big Green Zero Energy Audit and Energy Due Diligence, Big Green Zero also provides energy project development services. Project development services include planning and budgeting, conduct of requests for proposals and project quality assurance (making sure that building owners get what they pay for).
