Parliament Buildings and Sustainability

About this building

Parliament Buildings is a six storey Grade-B listed building originally constructed to accommodate the newly formed Government of Northern Ireland, established under the Government of Ireland Act 1920.

The grounds of Stormont Estate (224 Acres at the time of purchase) cost approximately £20,000 and the cost of constructing Parliament Buildings came close to £1.7 million. The Prince of Wales, later King Edward VIII, declared Parliament Buildings open on 16th November 1932 on behalf of King George V.

The building is designed in Greek Classical tradition, constructed by Stewart Partners Ltd under the guidance of architect Arnold Thornley, from Liverpool. He was a man who paid great attention to detail with many of the features in Parliament Buildings having symbolic reference. One example of this detail can be illustrated by the length of the building as it measures exactly 365 feet wide, representative of one foot for each day of the year. Arnold Thornley later received a Knighthood from George V in recognition of his architectural work.

Study our data

The data that we have provided below gives detailed information on how much energy is consumed in the running of Parliament Buildings and how much it costs. There are detailed breakdowns of weekly and monthly figures as well as total yearly figures since 2007. You can then see what environmental impact this energy consumption has had in the form of carbon emissions. We have also included statistics on how much waste has been produced since April 2011 including figures highlighting what proportion of it has been recycled.

Display Energy Certificate

Since 1 October 2008 public buildings in the UK over 1,000m2 have been required to display a Display Energy Certificate (DEC) prominently at all times. Display Energy Certificates were introduced by the government in response to the EU Energy Performance of Buildings Directive which all EU member states were required to implement by January 2009.

DEC’s are designed to promote the improvement of the energy performance of buildings. They are based upon the actual energy performance of a building and increase transparency about the energy efficiency of public buildings. DEC’s use a scale from A to G with A being the most efficient and G the least. The Display Energy Certificate for Parliament Buildings is available through the link below.
