    Free Lighting Hours Tool

    We were so frustrated at SustainSuccess with trying to find daylight hour tables for client locations that we wrote our own Excel/Google Maps/NOAA “mashup” to calculate lighting hours for any location on Earth! We are providing it FREE to fellow practitioners. Simply fill in this form and we’ll send you a download link.


    Ideas and Challenges

    Despite self-congratulatory case studies to the contrary, the reality is that Sustainability and Resource Efficiency are NOT EASY to implement successfully in organisations.

    In a series of blogs, articles, book reviews, and extracts from Niall Enright's book you will find hints, tips and suggestions to make Sustainability a Success.
