Gross internal conditioned floor area (m²)

The gross internal floor area that is conditioned (eg. heated and/or cooled)

% Occupancy during 12-month period

The percentage occupancy, for this form, must relate to the energy data collection period.

Is the project new-build or refurbishment?

Describe the extent of the work.(max. 300 words)

Did the project make use of existing fabric or structure? Did the project team evaluate whether existing elements could be retained and upgraded instead of demolition and new build? Was a building demolished on site? Give details of its condition, include listed status if applicable.

Airtightness (m³/hr m² at 50Pa)

Provide any other supporting information relating to the building specification. (max. 200 words)

Please include any sustainability certifications achieved.

Outline sustainability drivers, concepts, and specific environmental performance outcomes of the building.(max. 300 words)

How was sustainability considered during the architectural concept, form development, construction, and building end-use stages? Describe any performance analysis undertaken and the measured sustainability outcomes. Were there any special project objectives, challenges, or constraints? Was the design reviewed against the impacts of future climate change (e.g. future weather, flood risk, overheating risk)?  Are there any innovations in sustainable construction? What are the key indoor and outdoor water use strategies? Did the brief inform the sustainability strategy? What is the net-to-gross efficiency?

Predicted energy use (kWh/m²/y)

This is the total annual predicted regulated and unregulated energy use (measured in kilowatt-hours per metre squared per year based on the gross internal area (GIA) of the building).

Actual energy use (kWh/m²/y)

This is the total annual gross operational energy (electricity and gas) use (measured in kilowatt-hours per metre squared per year based on the gross internal area (GIA) of the building) taken from measured data.

Figures should reflect gross energy use and therefore should include energy used on-site from any on-site renewables. The measurement should be taken from energy meter readings (or energy bills + PV meter) for the building over a year.

If this metric is not applicable to your project, enter '0' (zero) into the data field and provide an explanation in the 'supporting information' textbox.

Is gas used on site?

Gas usage (kWh/m²/yr)

The actual annual gas usage (if applicable).

On-site renewable energy generation (kWh/yr)

The total annual renewable energy generated on-site, excluding heat pumps (if applicable).

Is the site connected to a district heat system?

Provide details of the district heat system (max. 200 words) (if applicable) 

What is the primary heating technology (for example gas boiler, gas combined heating and power, air/water/ground source heat pump)? If combined, please give an approximate split. At what temperature is the network delivering the heat? Is the heat upgraded in the building?

Potable water use (litres per person per day)

The total annual drinking water used on site, measured in litres per person per day (l/person/day) in domestic and non- domestic, and metres cubed per pupil per year (m3/pupil/yr) for schools, taken from measured data. If this metric is not applicable to your project, enter '0' (zero) into the data field and provide an explanation in the 'supporting information' textbox below.

Building design life (years)

The assumed building design life used in the assessment (typically 60 years).

Upfront carbon (KgCO₂eq/m²)

The greenhouse gas emissions associated with materials and construction processes up to practical completion (Modules A1-A5 of RICS Whole Life Carbon Assessment for the Built Environment). Upfront carbon excludes biogenic carbon sequestered within installed products at practical completion.

Life cycle embodied carbon (KgCO₂eq/m²)

The whole-life embodied carbon emissions associated with materials and construction processes (Modules A1-A5, B1-B5, C1-C4 of RICS Whole Life Carbon Assessment for the Built Environment).

Whole-life carbon assessment (KgCO₂eq/m²)

The total whole-life carbon emissions, including both operational and embodied carbon across the asset life cycle (Modules A1-A5, B1-B7, C1-C4 of RICS Whole Life Carbon Assessment for the Built Environment).

Carbon assessment methodology (max. 300 words)

Explain the basis of the carbon calculations provided.Confirm which RIBA Stage calculations were undertaken at, and state assumed building life and assessment boundary (cradle to gate/cradle to practical completion/cradle to grave). Confirm which life-cycle stages were included. If you have been unable to provide whole-building carbon figures, but have calculations for specific building elements, you can use this textbox to provide the data and specify how they have been reached.

Describe any strategies used in the building’s design to reduce embodied carbon. (max. 300 words)

The strategies used to reduce embodied carbon through the building's design, specification, procurement, and construction.

To what extent has the project considered the circular economy? (max. 300 words)

Explain how the design supports material efficiency, longevity, adaptability, disassembly, or future reuse. Give examples of recycled, reclaimed, reused, or low-impact materials used.

Explain the ecological strategy (max. 300 words) 

How does the project enhance biodiversity, increase green infrastructure or create opportunities for productive growing spaces (for example local food production)? Were considerations made for biophilic design? What measures have been taken to mitigate any loss of Category A and B trees? Is the project situated on designated landscapes (e.g. greenfield land, Areas of Outstanding Natural Beauty, locally designated landscapes)? If so, what measures have been taken to mitigate the impact on the environment? How are any biodiversity net gain benefits safeguarded for future years on the site?

Biodiversity net gain (BNG) %
