Windows / Doors / Roof lights

Your Openings Example

Windows 1.4 w/m2k

Patio Doors 1.4 w/m2k

Bi-Fold Doors 1.4 w/m2k

Doors less than 50% glazed 1.2 w/m2k

Solid Doors 1.0 w/m2k

Roof lights 1.4 w/m2k

If you have a supplier in mind they should be able to give you the values – if not we suggest you follow the examples on the right and ensure when ordering the doors and windows that they achieve these values.

These represent the values you need to be aiming for.

Ventilation

Your Proposal (only specify the main one if you are proposing a number of systems)

Examples

Natural Ventilation will be provided by opening the windows along with extract fans in kitchen/bathrooms/Utility and cloak rooms

OR

A balanced mechanical ventilation system with heat recovery will be installed

OR

Positive input ventilation from the loft is proposed

Please specify accordingly – if you have a make and model of any proposed mechanical system please provide details.

The top example (Natural Ventilation) will usually provide the best result unless pv is being provided which would reduce the cost of a mechanical heat recovery or similar system.

Internal Lighting

Your Lighting Examples

75% of the lighting will comprise dedicated Low Energy Fittings which is the minimum requirement under the Building Regulations

OR

100% of the lighting will comprise dedicated Low Energy Fittings

OR

20 light fittings are being installed 18 of which will be low energy.

Unless you have a lighting layout at this stage you will need to specify a % but must ensure that when purchasing the fittings you achieve the correct % of low energy lighting. If in doubt contact your electrical contractor for advice.

The model design in SAP 2014 requires 100% Low Energy Lighting so anything less than that will require improvements elsewhere.

Electricity Tariff

Your Tariff Examples

7 Hour Off Peak or10 Hour Off Peak orStandard18 Hour24 Hour

If unsure you will need to specify “Standard” These are the 5 choices to enter into SAP 2012

Main Heating

Proposed Heating Examples

89.5% Efficient Gas Combination BoilerRoom SealedFan FlueModulating Boiler with InterlockWeather Compensation 1

Delayed Start Stat2

RadiatorsAt least 2 independent Heating zones(e.g. Living Accommodation and Bedroom accommodation – separate room stats to control each zone)

If you know the make and model of boiler please specify. If unsure of the controls then we suggest you use our example. Also confirm which rooms if any will have underfloor heating.

The above specification is taken from the Model Design and you should be looking to match or better this.

Weather Compensation1 – a temperature sensor on the outside which sends information to the boiler on the external temperature – if the temperature changes outside, the boiler responds and starts to increase or decrease the radiator temperature to compensate. We will need to know the make and model of the sensor installed when producing the Energy Performance Certificate.

Delayed Start Stat2 – Delays the start-up of the heating, depending on how warm the room temperature already is at the time the central heating is scheduled to come on. Therefore during milder weather, when the ambient room temperature is normally higher, the heating start time can be delayed to avoid wasting fuel by switching the heating on earlier than necessary.

Secondary Heating

Proposal (if applicable) Example

Wood Burning Stove65% Efficient (min required under Building Regs)Installed by HEATAS EngineerIn/Not in a Smoke Control Area

Other examples could include electric fan heaters, oil heaters etc.

Enter Not Applicable if none is proposed.If you know the make and model of the secondary heating then please enter this. Ideally chose an appliance with an efficiency higher than 65%

You don’t have to install a secondary heating system but a wood burning stove will improve your ratings and may assist in getting a pass

Water Heating

Proposed Water Heating Examples

From the combination boiler

OR

150 litre hot water cylinder inside the dwelling80mm factory fitted foam insulationIndependent time control for space and water heatingCylinder StatFully Insulated Primary Pipework

If you know the make and model of hot water cylinder please specify. If unsure then we suggest you use our example.

The above specification is taken from the Model Design and you should be looking to match or better this.

Solar Panels

Enter details if solar panels are proposed to complement the hot water supply

Examples

Solar Panel Area (indicate if Aperture or Gross)Flat Plate Glazed 1

n0, a1, A/G ratio - if you can obtain these figures from the supplier then we can include them in the calculation which may give a better result than using defaultSouth Facing450 angle of elevationNone or little overshading 2

100 litre volumePump electrically poweredCombined Cylinder

Please enter as much information as you can particularly the first two rows and the volume – if you’re not sure then follow our example,

Solar Panels do not from part of the Model Design and will therefore usually only be required should you fall short in some of the other areas in the design.

Flat Plate Glazed 1 - Other options are Evacuated Tube or unglazed.

None or little overshading 2 – Other options for overshading are Heavy, Significant, and Modest – please select the most appropriate for your site.

Photovoltaic Panels

Enter details if pv panels are proposed Examples2.28 KW PeakSouth Facing450 angle of elevationNone or little overshading 1

450 angle of elevationConnected to the dwellings electricity meter

The first row you will need to obtain from your pv supplier. The other rows will depend upon their location on your dwelling. It would be usual for the panels to be connected to your own dwelling and not straight back to the grid.

PV Panels do not from part of the Model Design and will therefore usually only be required should you fall short in some of the other areas in the design.

They will however make a significant improvement to your ratings.

None or little overshading 1 – Other options for overshading are Heavy, Significant, and Modest – please select the most appropriate for your site.
