Project Overview

Objective

Use building thermal models to understand loads, comfort, and design options while keeping model inputs and assumptions traceable.

Role & Responsibilities

Mechanical engineering and coordinated design within the professional background shown in this portfolio.

  • Define building zones, fabric properties, internal gains, and occupancy schedules.
  • Review design temperatures and suitable weather information.
  • Assess heating and cooling loads in IES VE.

Engineering Features

The plotted monthly demand values are illustrative, not data from an employer or client project. Real assessments require project geometry, fabric, weather, occupancy, and systems information.

Model Assumptions

The plotted monthly demand values are illustrative, not data from an employer or client project. Real assessments require project geometry, fabric, weather, occupancy, and systems information.

Design Workflow

  1. Define building zones, fabric properties, internal gains, and occupancy schedules.
  2. Review design temperatures and suitable weather information.
  3. Assess heating and cooling loads in IES VE.
  4. Investigate thermal comfort and the effect of design options.
  5. Coordinate engineering findings with the HVAC design and wider project team.

Engineering Checks

Check zones and schedules, reconcile loads with engineering expectations, and inspect the sensitivity of results to modelling assumptions.

Study Limitations

Representative visualization created for portfolio purposes. No confidential client data is shown. The plotted values are not a certified energy assessment.
