1. Introduction

1.1. The VE-Toolkits

The IES VE-Toolkits are a set of analyses that can be run to help influence and direct early stage

building designs. These fast analyses can be run with basic model inputs to allow indicative

assessment of design options taking into account climate, building fabric, energy & carbon, thermal

loads, daylighting and solar shading. Further options offer an assessment of the potential for Low or

Zero Carbon technologies and water reduction.

Using the VE-Toolkits for LEED the building model can be appraised against LEED credits to give an

indicative result based on credits that cover daylighting, comfort, water and Renewables.

1.2. Access

The VE-Toolkits can be accessed from the IES <VE> plug-ins for Google SketchUp and Autodesk

Revit.

The IES Toolbar in each plug-in has a VE-Toolkits button that will launch the Toolkits dialog.

Autodesk Revit:

Google SketchUp:

3. Sustainability VE-Toolkit

The Sustainability VE-Toolkit is divided over two tabs; Overview and Sustainability.

The Overview tab can be used to give a greater understanding of the implications of the building

location by understating climate and uses this information to offer guidance on building fabric design,

materials and potential strategies for further investigation.

The Sustainability tab allows early stage analysis of Energy and Carbon emissions, Heating and

Cooling Loads, solar shading and daylight assessment and Water and Low or Zero Carbon

Technologies reviews based on building design and simple inputs.

3.1. Overview

Climate Metrics

Allows analysis of climate data for the location and summarises relevant metrics related to climate

that play a key role in understanding buildings and design responses. Output on ASHRAE/Koeppen-

Geiger climate classification, temperature, moisture/humidity, wind, precipitation, solar energy, diurnal

swing and Mahoney comfort stress analysis.

Sustainability Toolkit

VE 6.3 VE-Toolkits 8

Climate Index

A building independent rating created by IES. It provides designers with perspective on the potential

the climate has to affect the amount of energy a building needs to achieve occupant comfort. Heating,

cooling, humidification and dehumidification energy is explored. The output report includes global

comparison and breakdown of potential energy types.

Natural Resources

Building design and climate are interrogated to provide a report giving an indication of the potential

scale that solar energy, wind energy and rainwater resources could impact on the design.

Building Metrics

Allows an advanced understanding of the key characteristics of the building. Report includes

classification of skin or internally driven loads, surface area to volume ratios, glazing areas and

orientation, breakdown of solar and casual loads, thermal mass and natural ventilation form.

Materials Review

Report provides a summary of the materials used in the building includes predominant types and

potential impact of waste in the construction process.

3.2. Analysis

Energy/Carbon Simulation

Dynamic thermal simulation is run on the building model and report generated gives whole building

energy and carbon results (including comparison with 2030 Challenge benchmark), energy

breakdown by usage, monthly carbon emissions, room comfort levels (max/min temperature, humidity

and PPD) and peak room loads.

Select method to choose to include effects of external

solar shading and advanced solar penetration.

Water Review

Water review allows the investigation of potential ways the building design may benefit from water

reduction and through use of waste water technologies.

To define water usage (based on occupancy and fixtures) in the building and any waste water

technologies in use click the Edit appliance data button. Select the regulatory system (options are

LEED-USA, BREEAM, Greenstar or LEED-INDIA) then make changes in the Water Uses dialog.

The report generated will give results on overall consumption (with breakdown by end usage) and

water scarcity for the proposed and baseline designs. Water reduction and waste technologies are

reviewed and compared to give levels of effectiveness.

Sustainability Toolkit

VE 6.3 VE-Toolkits 11

Heating and Cooling Loads

Perform CIBSE or ASHRAE Loads calculations.

Select method from the options before running the

calculation.

The output graphically reports peak heating and cooling loads, loads split per usage and air flow

rates. There is also tabular display of breakdown of loads for each HVAC system and each room in

the building.

Solar Shading

Create an animation showing solar shading across the building including effects of local shading

devices.

Edit settings to change time of year results are

displayed for and alter the azimuth and altitude of the

camera view.

Daylight Assessment

Daylighting calculation is performed on the model to measure light penetration into the building

through external windows (advanced option also measures penetration through internal openings).

Select quality of calculation:

Simple – light is only measured through external windows

Advanced – light is measured passing through internal openings

Note: advanced calculations can take significantly longer to run.

Sustainability Toolkit

Rooms can be included/excluded from the calculation as desired by

using the Edit spaces in analysis button to access the Spaces in

analysis dialog.

The report shows total daylight illumination and daylight factor for all

rooms in the analysis and gives this as a % of floor area over the

fixed threshold 300lex (25 f.c.). Room by room breakdown allows

the rooms that are performing badly and are poorly lit to be

highlighted to help improve building design.

Low/Zero Carbon Technologies

Assess potential benefits from including Renewables and low-carbon technologies in the building.

These are related to simulation results and put in context of delivered Energy and carbon emission

mitigation and savings.

Select the Edit LZCT Data button to input details of any renewables, low carbon and green power

technologies that may be included in the building and to define Energy costs for the region that will be

used to calculate savings.
