The Scottish Parliament has secured a B rating for its Energy Performance Certificate (EPC).
IES Consulting used advanced 3D modelling and dynamic simulation of the Scottish Parliament building at Holyrood to determine the EPC rating due to the complexity of the structure.
The original design used natural ventilation, reduced air conditioning and Combined Heat and Power to increase the efficiency of the building.
David McEwan, UK Director of Glasgow-based IES and the energy assessor for the project, said: “Given that the building was designed to pre-2000 standards when awareness and understanding of energy efficiency in buildings was considerably lower demonstrates exactly how cutting edge the design was.
“This B rating is a testament to the high quality sustainable design of the building – where energy efficiency standards have been raised substantially by around 30% since the building was designed in 1997.”
Enric Miralles’ plan for Holyrood made sustainability a central element of the design. The environmental impact of the building was reduced through careful design and selection of materials.
Particular attention was given to minimising energy consumption through the increased use of natural ventilation and daylight, a reduction in the need for air conditioning and the use of innovative technology such as Combined Heat and Power plant.
David Fairhust, the Scottish Parliament’s Environment manager, said: “We are pleased the energy performance for the entire Parliament building has been assessed as achieving a rate which meets regulations introduced in 2007.
'This rating clearly demonstrates the conscious efforts which were put into the design and construction of Holyrood to ensure it operated as an energy efficient building.“
