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.

3 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. 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.

4 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. 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.

5 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. 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.

6 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. 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.

7 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.

8 sustainability toolkit VE VE- Toolkits 12 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 ). 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.

VE- toolkit for LEED-USA Measure building performance against indicative LEED rating system covering credits for daylighting, comfort, water and renewables across LEED NC , LEED Schools V1/V3 and LEED Core and Shell V2/V3 rating systems. Select rating system then generate indicative reports for each credit. Daylighting sustainability toolkit VE VE- Toolkits 15 This assessment covers LEED Credit 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 Rooms can be included/excluded from the calculation as desired by using the Edit spaces in analysis button.

10 Define primary and secondary spaces or exclude any rooms by unticking in both columns. The output reports total daylight illumination and daylight factor for all rooms in the analysis and provides indicative pass/fail based on 75% of floor area over the fixed threshold (269lux). Results of previous runs are displayed for easy comparison and room by room breakdown allows badly performing rooms to be highlighted to help improve building design. sustainability toolkit VE VE- Toolkits 16 Comfort Covers LEED Credit ASHRAE 55 2004 compliant assessment method occupied area must meet predicted mean vote (PMV) + to Rooms can be included/excluded from the calculation as desired by using the Edit spaces in analysis button: Apache dynamic simulation is performed on building and report provides an indicative pass/fail based on rooms that fall within comfort limits.
