BUILD Sustainable Building Awards 2023

  • On behalf of the team at BUILD, I’d like to thank you for taking part in our much-anticipated Sustainable Building Awards, I hope all has been well since we last reached out.
  • As this is our sixth year of running this program, we are proud to host former and new awardees who champion an promote sustainable exploration and support coastal communities worldwide.
  • I am delighted to share with you today that, following on from our extensive research period, National Green Specification has been successful this year and has gone on to receive:

Best Green Retrofit Design & Decision Tools Provider 2023 – UK

  • How National Green Specification earned this recognition:
  • To determine the results, BUILD‘s judging panel and research team consider the commitment, expertise, and innovation shown by nominees through nomination information, votes, any supporting evidence, along with the results from their own comprehensive fact-checking and research process.
  • Our merit-driven approach has brought us much success and commendation throughout its use and enforces our stance that victors are not determined by popularity of votes, but by their contributions!

GRC Green Apple Commended Award Winner 2023

  • Green Retrofit Calculator V1
  • Submitted 30th May 2023
  • Awarded 13th September 2023

    PROJECT:Green Retrofit Calculator Version 1

    We introduced a new Green Apple Environment Award last year – ‘Commended’.

    Our Commended winners have won not quite enough points for a Gold, Silver or Bronze trophy, but the judges thought their entries deserved some recognition and encouragement to continue with their environmental endeavours.

    For instance, some of our Commended winners’ projects are in their infancy, making it difficult for the judges to mark them on actual achieved outcomes.  Others contain an element of environmental effort, but operate on a wider level and would probably stand a greater chance of success in our Corporate Social Responsibility Awards.  Many factors come into play.

    The reason I am giving you this background information is because your entry has been chosen for a Commended Award.  Congratulations!

    We do not normally announce who has won what until the presentation ceremony itself, but since this is a new award and comes in the form of a certificate, rather than a trophy, we thought it only fair to make you aware of this before you decide whether to join us for the prestigious awards ceremony in The Houses of Parliament, Palace of Westminster, London on Monday, November 20, 2023.

    Your Commended certificate will be emailed to you after the event, free of charge.

    Congratulations on your achievement.

  • Yours sincerely,

    Karl Tullett Director
