| :chart-simple: Data | :file-xls: Cell Code | :message-pen: Instructions |
| Energy Assessment | D5-7 | Select TRUE from the dropdown menus if the entity performed an energy technical building assessment (TBA - see definition below) during the last 3 years to identify opportunities within the asset. 
Technical Building Assessment: Energy - Covers the products or systems that use less energy for the same consumer benefit.

Technical Building Assessment: Water
- Covers the conservative use of water resources through water-saving technologies to reduce consumption.
Leaving dropdown menus blank is equivalent to FALSE. |

### Terminology
**Technical building assessment**
> Any formal, documented building assessment that 1) is specific to the building at hand (i.e., not involving generic input), 2) is undertaken under technical expertise, and 3) aims to help the entity understand available energy, water, and/or waste improvement opportunities.
>
> * Persons with technical expertise can include, but are not limited to: structural engineers, building envelope surveyors/consultants, HVAC specialists.
> * Assessment types can include, but are not limited to: audits or evaluations of the building structure and materials, operations, and/or utilization by occupants.

## Scoring
Scoring: How does GRESB score this indicator?
Each type of technical building assessment is assigned a maximum number of points as follows:
1. Energy = 1 point;
2. Water = 0.67 points;
3. Waste = 0.33 points.
**Percentage number:** The coverage percentage reported is used as a multiplier to determine the assigned score.

## Frequently Asked Questions
Can I use a building certification as a technical building assessment?
A building certification alone might **not** be sufficient to serve as a Technical Building
\
Assessment. While a building certification might focus on specific aspects like energy
\
performance, a technical building assessment is broader and requires a formal evaluation by
a technical expert, covering structural processes, outcomes, and recommendations for
\
improvement.
