Our New Build Services are based on the new Part L Building Regulations using passive house standards.
We offer energy efficient services and support the construction team during the works. We offer free consultation on any measure that helps achieve the more challenging A3 rating, and comply with current Part L regulations.
It is better to inspect your drawings at design stage to ensure compliance with current Building Regulations. We should visit the site during the works when the building envelope is complete and before second fix. We can then check that the building is still compliant and carry out an Air Tightness Test.
Finally, when the building is finished, we will carry out an Air Tightness Test, Certify for Part L Compliance and publish a BER Certificate. These Reports are all now mandatory for New Builds.
DEAP Compliance Report
Building Control now insist that DEAP calculations are included with the commencement notice to ensure the building design is compliant with building regulations.
The Energy Performance Coefficient (EPC) and Carbon Performance Coefficient (CPC) which is calculated using DEAP, must not exceed their maximum permitted values.The homeowner and designer must be aware of this level of detail at commencement notice stage.
Smart Energy Savings assist the construction team (Architects, Developers, Builders & Self Builders) to comply with Part L and beyond.
We can produce Building Specifications based on the above items that ensures compliance with the Regulations.
Your finished building will be cheaper to heat, boast improved comfort levels, and will ultimately provide a happier, healthier environment for all occupants.
It is important that insulation in the roof, walls and floor work together to conserve heat, and reduce your building's overall heat load. It is better to use Acceptable Construction Details (ACDs) to improve the buildings energy rating, which also makes it easier to achieve Part L compliance.
We offer advice on insulation continuity to reduce thermal bridging and heat loss. We can then calculate a lower Thermal Bridging Factor (<0.08W/mK) to assist with building compliance.
An Airtightness Strategy is all about avoiding Gaps,which occur in contractual arrangements and in the design process, as well as between components during construction. Airtightness needs to be a priority throughout the construction process and a strategy should be adopted from the start.
We offer free consultation and advise over the phone if you send us your drawings.
It is important that you agree on the Air Tightness level from the start as it will determine the level and type of ventilation system to comply with Part F of the Ventilation Building Regulations. We will identify the amount of airbarrier membrane thats required for your air tightness target.
Smart Energy Savings are certified Air Tightness Testers. All domestic new builds should be constructed to a minimum air permeability requirement of 7m³/hr/m² at 50 Pa. The airtightness test must be carried out before the building is habitable in accordance to European Standard EN 13829.
It is advisable to carry out a quality assurance test when the air barrier is complete and not covered up. This allows for leaks to be identified and sealed with minimum disruption. It is also a good time to collect ACD information and ensure that the building will comply with regulations.
We will seal up unwanted leaks during the test and help you reach a better air tightness level.
If you send us your drawings we can design a suitable MVHR system and produce a schematic layout of the design. We can arrange for a qualified installer to fit the system and to balance and commission it on completion.
A renewable energy source is now required in all new builds in accordance with the Building Regulations (10kWh/m2/yr for thermal or 4kWh/m2/yr electrical). We can advise you of what is required for you to comply with the regulations.
It is not always clear which systems are more suitable. We will check a combination of systems and advise you on the most cost effective. The most common are Solar Panels / Collectors / Photo Voltaic, Wood Pellet Stoves, and Heat Pumps.
We offer free consultation to help you choose the best renewable technology and will connect you with professional contractors.
DEAP Certification Report
To fully comply with the relevant Building Regulations (2008 or 2011 Regs), it is strongly recommended that DEAP calculations are used to satisfy Part L. This also ensures that the homeowner will achieve a better energy rating when publishing a BER Certificate, such as an A3 for compliance to 2011 Regulations.
Photographic ACD proof signed by the Builder should be recorded during construction, when certain work is covered up. The Certifier will also need a final Air tightness Test Report from a certified Tester, along with many other material and heating system certificates.
Final BER Certificate
It is now mandatory to publish a final BER Certificate when a building is given planning permission after the 9th January , 2013.
The BER Assessor can only publish a Certificate based on the information gathered from the survey and recorded by the homeowner. It is the responsibility of the homeowner/builder to file all information during construction so that the Assessor can avail of all relevant proof when publishing a BER Certificate.
It is a requirement that a final BER must be published within 2 years of publishing a Preliminary BER, when a house is sold off the drawings.
Building Control will not issue a certificate of completion if the building fails to comply to the current Building Regulations. Homeowners/Builders can not occupy or take ownership, if Building Control refuse to add their building to the National Register. It is solely the responsibility of the homeowner / builder that the finished building is compliant.
"We wanted to achieve an air tightness level less than 2m3/m2 /hr since we decided to go with a Mechanical Ventilation with Heat Recovery (MVHR). We emailed our drawings to Smart Energy Savings and they designed a suitable air barrier line to allow for a low air tightness level. They also organised the installation of the air barrier membrane and carried out an air tightness test." ----- Joe Curry, Selfbuilder, Sligo.
