Assessment procedure & added value

Prior to appointment:

  • Free web based consultation during the quotation stage

After appointment:

  • We liaise directly with the Client, design team, Building Control and Planning Officers to agree environmental performance targets and assessment strategies required on your project.
  • We create computer generated 3d building models at any RIBA Stage, although testing from concept “sketch” stage onwards offers the maximum added value.
  • We provide a ‘shopping list' of options and innovative trade-offs to establish the optimum building performance design solutions.
  • We offer a post Planning and Building Control Application technical support service which often includes a degree of ‘technical negotiation' to help secure the relevant approval
  • Our latest service allows our clients to outsource the time consuming process of searching and comparing the global marketplace for MCS Approved micro-generation products to our expert in house team, who have been specifying and buying energy related products for over 25 years.
