Air tightness testing is a process in which the building envelope is tested to quantify the air
The test measures air leakage rates through a building envelope under controlled pressurisation and depressurisation.
To comply with the current Building Regulations all new dwellings are required to have a SAP (TER/DER) calculation which should be carried out before construction commences. On completion the SAP is re-calculated using “As- Built” information.MORE INFORMATION

for all properties being sold

A Thermographic / Thermal image survey is a non-invasive means of monitoring and diagnosing the condition of a building.
Our thermographic surveys can provide extremely useful information about the thermal properties of your building.

We offer cost effective consultancy advice on materials and detailing at early design stages to enable changes to be made to the design before mistakes are made on site.
At the Construction stage we work with the Design Team and Building Contractors to ensure that the building has the best chance of passing the Air Leakage Testing criteria first time. We also pride ourselves that should your building fail to achieve the necessary air tightness our experienced trained staff endeavour to track and identify the problems and retest often at no additional cost whilst we are at
site in order to achieve a satisfactory result.
To comply with the current Building Regulations all new dwellings are required to have a SAP (TER/DER) calculation which should be carried out before construction commences. On completion the SAP is re-calculated using “As- Built” information such as the boiler details, pressure test result and details of any renewable energy appliances (solar) installed. This then provides the information which is included in the EPC (Energy Performance Certificate).
SAP CALCULATION NEW BUILD SAP.
All new dwellings must now have a SAP calculation performed in order to demonstrate compliance with Building Regulations.
If you build an extension where the glazing is over 25% of the floor area, then we can undertake a SAP assessment to demonstrate compliance with Building Regulations.
What do I need to provide?
Floor plans, sections & elevations
Orientation e.g. site plan Construction specification of walls, roofs and floors
Specification for all windows Primary & secondary heating systems Renewable technology (if any)
What is included in the SAP Reports?
• All the relevant SAP documentation required for compliance with the Building Regulations;
• Additional necessary recommendations to ensure a pass is achieved every time;
• U-value calculations for submission to Building Control; and
• Comprehensive advice and support throughout the whole process.
It is now a legal requirement for all properties being sold or offered for rent to have an Energy Performance Certificate (EPC). Failure to comply could result in a £200 fine per complaint. Energy First NI offer both Residential and Commercial EPC at competitive prices.
We will not be beaten on price Energy First NI will take a short survey of your property by your instruction. The survey will take into account factors such as: - Location - Wall Construction and size of property - Hot water and heating systems - Insulation and Glazing This information can be processed to produce an EPC certificate and available - for you to download within a short space of time. - Whilst surveying we can offer energy/cost saving advice. - We can also provide floor plan drawings whilst onsite.
Energy First NI often conduct thermographic surveys for private clients who find that their heating costs have soared or who have a particular concern with a room, extension or the whole house. We can carry out a survey on your home or property and produce a report which will clearly identify heat loss or energy wastage. Very often the problems are not what the home owner thought they would be. Preparing for a Thermographic/ Thermal Image Survey Surveys will normally be carried out during the winter months - between 1st October and 31st March. Our survey are taken either early morning or evening, In order to maximise the difference in temperature between the building and the outside air, we recommend that the house is heated prior to our visit. Ideally, the house should be heated for 10-12hours to a comfortable room temperature (19-21°C), but particularly during warmer weather, there may be extra benefit in heating the house to a higher temperature - say 24-26°C.
It is important that the house is heated for several hours prior to our visit - this allows the fabric of the building to warm up, which requires considerable time. It also allows any heat losses in the ceiling of the upper floor to heat the attic sufficiently to show up minor heat loss through the roof covering. The Survey We will photograph your property with our thermal imaging camera from various angles at front and rear. The survey does not take very long, and we would normally expect to produce around 10 good quality images of the building. Other areas of interest may also be photographed at the same time if required (eg underfloor heating system, boiler, hot water cylinder, insulated pipes etc). We generally aim to complete the survey in around 30-60minutes.
