Cal Bailey shares his views and experiences of the importance of planning for sustainability from the outset of a project rather that adding features later.Green engineering is intrinsic to any sustainable development and needs to start from a blank sheet of paper, rather than becoming merely a bolt on at a later stage of a project. Considering green measures at the upfront planning stage is the only way ensure the best use of natural resources in every element of work in order to achieve the lowest possible carbon emissions for that building.
Elta Rick Stein restaurant
As part of the extensive refurbishment of the Seafood Restaurant of Rick and Jill Stein in Padstow, Elta was called on to provide extract power for three canopies in the main kitchen. One difficulty was that, being typical of many Cornish buildings, the kitchen is halfway below ground level and there are 16 guest rooms above the restaurant — so noise levels were a big consideration.
