3 Introduction 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.

4 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: sustainability toolkit VE VE- Toolkits 5 2. Settings Units - Toggle units between SI (Metric) and IP (Imperial). Combined Report - Display all previously generated results in a single report. Save - Save all settings. Help Launches the VE- toolkit User Guide. sustainability toolkit VE VE- Toolkits 6 3.

5 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.

6 sustainability toolkit VE VE- Toolkits 7 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 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.

7 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.

8 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. sustainability toolkit VE VE- Toolkits 9 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.

9 Select method to choose to include effects of external sustainability toolkit VE VE- Toolkits 10 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.

10 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 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.
