IMPORTANT NOTES

1. Please read carefully the notes on the following pages which summarize the

information we have extracted from your plans. We have highlighted in red areas

that in particular require your attention. Please advise us without delay if there

are any inaccuracies.

2. Copies of the Accredited Construction details required for your project have been

supplied to you along with this report. If you do not intend to follow these then

you must contact Mark Sheehan Building Consultancy for further advice.

3. It is VERY IMPORTANT that any changes that will affect the SAP calculation are

notified to MSBC to ensure that the dwelling will still comply with the Building

Regulations. If the DER is only just below the TER then what appears to be a

minor change could result in the dwelling no longer complying and Building

Control may refuse to issue a completion certificate.

4. It is equally VERY IMPORTANT to notify MSBC of any changes in the heating

and/or hot water as this may have a significant effect on the calculation. For

example changing from Gas to Electric or Oil is likely to result in a failure.

5. Responsibility for notifying MSBC of any changes rests with the Client, Builder

and Architect.

6. MSBC will not make a charge for amending the Design SAP unless the changes are

significant and / or frequent.

The following information will be required on completion, without it default

values will have to be used and the dwelling is likely to register a fail under the

Building Regulations.

You should supply items 1 and 2 BEFORE you have the Pressure Test done as any

changes may affect the Pressure Test requirement.

1. A statement from the developer, or equivalent person who is the client for the

building’s construction, that the dwelling has been constructed in line with this

design and, if not, what the differences are between the constructed dwelling and

the design.

2. A copy of the Pressure Test certificate relating to the dwelling.

3. A signed statement that the Constructive Details required for your project have

been followed.

4. The full postal address including the postcode

Without this information we may be unable to issue the Energy Performance Certificate

which could hold up the sale of the property.

Construction Specification

Issue 1

Produced using information provided by the contractor / owner / architect and

incorporating any amendments needed in order to ensure a pass i.e. a DER that is no

greater than the TER.

Construction Specification The following tables detail the construction, heating, hot water and renewable energy

proposals in the dwelling.

It is important to note that changes to any of these will affect the SAP rating and you are

advised to check with us the impact of making any changes.

Where available we have specified the thickness of any insulation and it’s K value.

Substituting with a different insulation with the same thickness but a lower K value

will give you a better result. If the insulation has a higher K value you will need to

increase the thickness and must contact us for further advice.

The blue items in the left hand column are the figures / details entered into the

calculation.

A brief description is provided in the right hand column to assist you.

Items in red require your particular attention

Items in purple contain goodwill advice

General

Particular attention must be made at all junctions of construction. The calculation has assumed that you will be following Constructive Detailing details a full set of which has been included with your Design SAP calculation. You will need to sign a declaration on completion that you have followed these details

AIR TESTING

4.00 The property will need to be Pressure Tested on completion and this is the figure you must achieve based on the construction specified to date. This figure may increase / decrease if you make changes to the construction. Care must be taken to seal all junctions during construction otherwise you may not achieve this target. You will need to provide a copy of the Air Testing result on completion

VENTILATION

Balanced Mechanical Ventilation with Heat Recovery Greenwood Fusion HRV2

Without this the dwelling is not showing a pass. If traditional extract fans are proposed then improvements will need to be made elsewhere which is likely to be solar or pv panels or a renewable heating source. You may wish to obtain costings for other options. We have modelled the house using a Greenwood Fusion HRV2, if another system is proposed please contact us prior to purchase so that we can check compliance is still achieved.

Lighting

75% Low Energy Lighting inside Energy Efficient External Lighting Standard Electricity Tariff

This is the minimum requirement under the Current Building Regulations. You are advised to discuss the light fittings with your Electrical Contractor to ensure Energy Efficient fittings are used to meet this requirement. Please advise if the property will be on a 7/10 hour Off peak Tariff or 18 hour / 24 hour Tariff. Contact your proposed energy supplier for details.

NOTES ON THE FIGURES DISPLAYED UNDER THE PROPERTY DETAILS ABOVE

SAP RATINGThis is the SAP rating for your house. It is based on the energy costs associated with space heating, water heating, ventilation and lighting less cost savings from energy generation technologies. It is adjusted for floor area so that it is essentially independent of dwelling size for a given built form. The SAP rating is expressed on a scale of 1 to 100, the higher the number the lower the running costs.

ENVIRONMENTAL RATINGThis is the Environmental Impact rating for your house. It is based on the annual Co2 emissions associated with space heating, water heating, ventilation and lighting, less the emissions saved by energy generation technologies. It is adjusted for floor area so that it is essentially independent of dwelling size for a given built form. The EI rating is expressed on a scale of 1 to 100 + , the higher the number the better the standard.

CO2 EMISSIONSThis represents the Carbon Dioxide emissions from your dwelling expressed in tonnes per year.

GENERAL REQUIREMENTS COMPLIANCEPass demonstrates that your proposals meet the Building RegulationsFail means that you will need to make enhancements in order to acheive compliancePlease note that although you may be meeting both the TER and TFEE requirements (see below) you may be failing under other items within SAP - refer to our report for details.

DERThis is the calculated Co2 from your dwelling expressed as kg of Co2 per square meter of floor area and must NOT exceed the TER otherwise your dwelling will not meet the requirements of the Building Regulations.

TERThis is the Target Emission Rate for Co2 that your dwelling must meet

DFEE (The actual Fabric Energy Efficiency of your dwelling)Fabric Efficiency is the amount of energy your house needs for space heating and cooling and is measured in kilowatthours per square meter per year. Unlike the DER it only takes into account the performance of the building fabric (walls/floors/roof/openings) and does not include any services/renewables. The result must not be more than the TFEE (Target Fabric Energy Efficiency) otherwise your dwelling will not meet the requirements of the Building Regulations.

TFEE (Target Fabric Energy Efficiency)This is the Target Fabric Efficiency that your dwelling needs to meet.

PERCENTAGE DER<TERThis the amount (expressed as a percentage) by which your dwelling is passing / failing on Co2 emissions

PERCENTAGE DFEE<TFEEThis is the amount (expressed as a percentage) by which your dwelling is passing / failing on Fabric Efficiency.

This document is a Predicted Energy Assessment for properties marketed when they are incomplete. It includes a predicted energy rating which might not represent the final energy rating of the property on completion. Once the property is completed, this rating will be updated and an official Energy Performance Certificate will be created for the property. This will include more detailed information about the energy performance of the completed property.

The energy performance has been assessed using the Government approved SAP2012 methodology and is rated in terms of the energy use per square meter of floor area; the energy efficiency is based on fuel costs and the environmental impact is based on carbon dioxide (CO2) emissions.
