1. SAP Energy Assessments (PartL1A Building Regulations)
Assessments are carried out from scaled plans provided, along with the specification of a project. Drawings will usually include floor plans, elevations, and sections of the building involved, along with a site location plan. (These documents posted, or emailed to us in pdf format). The aim is to ensure that the Dwelling Emissions Rate (DER) is either equivalent to or lower than the Target Emissions Rate (TER) to ensure Building Regulations compliance.
With the 2013 amendments to the regulations, came an additional threshold which relates to the fabric energy efficiency only of the property.
Once the initial assessment has been carried out, a list of any assumptions made along with a list of recommendations is emailed or posted to our client for their approval or amendment, and once their response has been received by us, any amendments are made, and the assessment is finalised at design stage, and the Design Final Report for submission to Building Control is produced, along with the Predicted Energy Assessment (PEA). These are then emailed or posted.
Once the construction is complete, the As Built Final Report can be produced upon receipt of written confirmation from our client that the construction has followed the specification upon which the original SAP assessment was based, otherwise if there have been changes to that specification, details of what those changes are so that the final report can be amended to reflect them. In addition to this information, we will also require details of the results of any air permeability tests that have been carried out, so that the As Built Final Report can also incoporate those.
Finally the full new address and postcode are required so that the property can be registered with Landmark and theEnergy Performance Certificate be raised for the new occupants of the property .
2. SAP Energy Assessments (Part L1B Building Regulations)
As in SAP assessments for complete newbuilds, scaled plans are required, along with a specification of both the existing building, and the intended extension / conversion work to it. We will carry out two assessments, one based on the existing building with the work carried out in line with Part L1B of the Building Regulations, and the other assessment will be based on the existing building and the intended extension / conversion with the work carried out as proposed. A comparison in total carbon emissions between the two assessments is made, and any recommendations that are appropriate to compensate for excessive glazed areas, or less than ideal thermal efficiency of any of the elements are notified to our clients. Once agreement on this point has been reached, and the total carbon emsissions figure of the proposed work is either equivalent to or less than the notional Building Regulations figure, the Design Final Report and Predicted Energy Assessment are produced for submission to Building Control.
Once all the work is complete, (with the exception of air permeability tests as these are not required in the case of Part L1B assessments), the format follows the newbuild arrangements as set out in the previous section.
3. Energy Performance Certificates (EPC) for domestic dwellings
We carry out surveys on existing domestic dwellings, producing the now mandatory Energy Performance Certificate to be used in marketed sales, and also as required since October 2008 for all domestic rented properties. Additionally, we work for a number of Housing Associations, carrying out sample surveys of their housing stock, and also providing EPCs and Survey Reports for their void properties.
4. Floorplans
We carry out floorplans surveys for estate agents, producing plans in both 2 dimension as well as 3 dimension, for inclusion with the sale particulars.
5. Home Energy Efficiency Audits
We will carry out an energy efficiency audit of your home, producing a draft EPC showing the current rating of the property, along with recommendations as to how improvements can be made to its SAP rating and carbon emissions footprint. We will look at the space and water heating , glazing, lighting, building fabric, insulation, controls, renewables technology, and make appropriate recommendations and provide you with various options along with guidance as to the cost of those improvements. Once improvements have been made, we will then carry out a new audit, and from that produce your new Energy Performance Certificate. Immediate savings should be made in the energy usage of your property, and additionally, should you then subsequently put it up for sale, then the Certificate lasts for ten years, and can be used to sell or let out your property.
6. U-Value Calculations
We can provide U-Value calculation services, and can model various options of construction on any of your building elements that you require them for. Along with this service, we are happy to advise on the best constructions, as well as the most appropriate insulation materials.
7. Thermographic Surveys
We will visist site and carry out all aspects of thermal imaging work including building, electrical and mechanical. We can cover all forms of thermography from electrical and insulation surveys for insurance purposes, to leaks in steam pipes. From the initial site survey, we will produce a fully bound report, comprising of thermagraphs and photographs, along with individual report sheets of faults found, plus any relevant recommendations and comments.
8. Air Permeability Testing
Under Part L1A of the Building Regulations, it is mandatory to carry out air permeability tests on any development that consists of three or more dwellings. Tests however are often carried out on less than three dwellings, as a means of avoiding the SAP calculation default figure which adds a handicap to the assessment should a test not be carried out. It also provides a means of ensuring the efficiency of the building envelope.
Qualified engineers will visit your building site with equipment for testing air leakage on your newly built domestic dwelling/s. Recommendations will be made should there be a failure, and the building/s retested.
Once testing is complete, certificates are then issued for submission to the SAP Assessor for inclusion in the As Built Final report for Building Control.
