Designed by Rees Pryor Architects for client Cambridgeshire County Council and built by contractor SEH French, the project involved the creation of a waiting room and associated facilities for park and ride users, as well as an exhibition space which showcases renewable and low carbon technologies.
This innovative and thermally efficient new building will become a learning resource that will showcase the very latest in green technologies and is targeted to achieve an excellent BREEAM rating, the first in Cambridgeshire.
The high level of thermal efficiency is testament to the technologies used in the construction and operation of this building which include photovoltaics, a ground source heat pump, green roof and 220m2 of Hembuild®.
Hembuild® is a factory produced system that consists of a timber cassette filled with Tradical® Hemcrete®. The timber cassette forms the buildings structural frame, for low rise (up to 3 storey) buildings to be created. Produced under a factory a controlled environment, the cassettes are delivered to site for fast track construction.
Hembuild® can be supplied in a range of U-Values from 0.10 to 0.22 W/m2K to provide a thermally efficient building envelope. Its unique thermal inertia means that the building has a very stable internal environment and greatly reduces the energy usage. Its offsite production process and use of renewable materials also has minimal environmental impact making the system ideal for the new low carbon public exhibition centre at Longstanton Park & Ride.
By using Hembuild® customers get the best of both worlds – modern methods of construction and inherent sustainability - with a quick build and a predictable programme at all times of the year, giving the thermal advantages of solid wall construction in a build time of lightweight timber frame.
“The controlled factory production environment of Hembuild® enabled us to stay in line with the restricted timescales of the project but also retain the sustainable low carbon design approach,” said Chris Wilkie of Rees Pryor. “Working with Lime Technology in the development of this project has been a very positive experience.”
Lime Technology can supply factory made Hembuild® panels to site and include the render, doors and windows to leave a fully tested airtight shell, ready for services and second fix.
The system can be used to meet high levels of the Code for Sustainable Homes and for BREEAM excellent buildings such as schools and commercial buildings. Hembuild® is a registered trademark of Lime Technology and has patents pending on the system.
