This video tutorial introduces how to add a new material in the Zebra EC database by importing embodied carbon factors and other required indicators from an Environmental Product Certificate (EPC) of the material into the database.

This video introduces how to use Zebra EC to calculate embodied carbon of a building using inbuilt database.

In this video we discuss the inter-dependency between different design requirements when designing building for their energy and carbon impact

This tutorial goes over the summary sheet in the Zebra model. In this sheet the outputs of the model are summarised, as well as whether or not the design requirements have been achieved

Embodied carbon is the carbon associated with construction, maintenance and demolition of a building. In this tutorial we cover the embodied carbon sheet in the Zebra model

In this tutorial we describe how building systems are defined in the Zebra model. This includes defining the energy demand of these systems, or the energy generation in the case of PV panels. It also includes defining the fuels these systems use, which will affect the operational carbon calculations

In this tutorial we cover the space conditioning sheet in the Zebra model. Most of the content of this sheet is summaries of the heating and cooling demand for the building based on previous input sheets. However, the sheet does contain some inputs, relating to ventilation systems and heat recovery

This tutorial describes how to define incidental gains in the Zebra model. Incidental gains are those arising as a side-effect from other processes, such as the heat from electrical appliances, and body heat from occupants of the building.

In this tutorial we discuss how we define the thermal losses that occur due to the movement of air in the Zebra model. This includes uncontrolled movement of air through infiltration, as well as controlled air movements through ventilation systems.

This tutorial covers how we define glazing in the Zebra model. Glazing is more complicated than the other input sheets for the building fabric, because glazing is a source of gains through solar irradiation, as well as losses. Furthermore, we have to account for the more complex losses though the glass and frame of the window.

Thermal bridges are elements of the building fabric which have significantly worse U-Values than the general material. In this tutorial we describe how thermal bridges can be allowed for in the Zebra model.

This tutorial covers have roofs are defined in the zebra model. You can define up to three roof elements by specifying their U-Value and area.

This tutorial explains how we define losses through the ground floor of the building in the Zebra model. This input sheet only requires a single area and U-Value for the ground floor. However, there is some additional complexity due to the thermal buffering effect of the ground, or the cavity beneath the ground floor.

This tutorial covers how we define the opaque fabric of the building, i.e. walls and unglazed doors. It covers defining wall and door elements, how they interact with glazing within them, and graphs presenting outputs.

This is an overview of the requirements sheet on the Zebra model. It covers defining the carbon and energy design philosophy (e.g. is it a zero carbon building) and defining some fundamental characteristics of the building (e.g. its floor area)

This is an overview of the requirements sheet on the Zebra model. It covers defining the carbon and energy design philosophy (e.g. is it a zero carbon building) and defining some fundamental characteristics of the building (e.g. its floor area).

This tutorial is a brief overview of the layout of the Zebra spreadsheet. It covers the basic layout, complexity level, the summary sheet, calculators and license sheet. Subsequent tutorials will go into different aspects of the model in much more detail.

An introduction to the model. This video covers the scope of the problem, and the solution provided by Zebra
