ASHRAE are one of the foremost industry pioneers in the decarbonization of the built environment and their new global Headquarters building in Atlanta, renovated to operate as a net-zero-energy (NZE) building, is testament to this. The project design team, which includes IESVE users, Integral Group, employed a range of innovative design strategies to achieve this net-zero energy ready building.

Subsequent building performance analysis from a group of ASHRAE Technical Committee 4.1 Members, including IES’ Liam Buckley, highlighted some of the simulation-aided design analysis on this ASHRAE Headquarters building. The following overview summarizes the many innovative categories worth highlighting from the project, in which an IESVE building performance model was able to support.


(1)   Net-Zero Energy Building

ASHRAE’s new headquarters is designed to operate as an all-electric at Net-Zero Energy (NZE) building, thanks to the installation of a 332-kW photovoltaic (PV) system. The PV system is a combination of three sub-arrays, which are sub-metered in the Building Energy Model shown below:

187 kW ballasted rooftop array on east & west wings
65 kW ground mount on a south-facing hill adjacent to the building
81 kW ground mount situated in an unused section of a car parking area

(2)   Simulation throughout Design Phases

Thanks to the PV installation, a limiting Energy Use Intensity (EUI) of 21 kBtu/ft2 was targeted for this existing building refurbishment.  Iterative design options throughout the design phases resulted in a range of low-energy solutions. These include:  

A reconfigured window-to-wall ratio (WWR) and 18 new skylights.
Common Dedicated Outdoor Air Systems (DOAS) for outdoor air ventilation, coupled with enthalpy heat recovery.
Radiant panels and Ceiling Fans.
Demand Control Ventilation (DCV) in high occupancy spaces and Displacement Ventilation (DV).
Six water source-heat pumps (WSHPs)

(3)   Optimized Load Calculations using the ASHRAE Heat Balance Method

For over 20 years, ASHRAE has recommended the Heat Balance (HB) Method as the preferred method for calculating heating & cooling loads. With such a low-energy target in mind, a considerate zoning strategy and accurate load calculations are very important.  Included in the load’s analysis:

Horizontal and vertical solar shading on most windows.
Sensible Loads analysis at the zone and Latent Loads Analysis at the AHU.
Heat gains from the reversible ceiling fans.
Analysis of Adaptive Thermal Comfort for Occupants and Operative Temperature.

(4)   Exceptional Daylight Performance (Spatial Daylight Autonomy, sDA)

Of the many daylighting metrics available, Spatial Daylight Autonomy (sDA) likely best considers the annual sufficiency of indoor daylight levels. In the in regularly occupied spaces of the ASHRAE HQ, the working plane analysis areas are considered for sDA, for the percentage that meets a minimum illuminance level of 300 lux, for 50% of the operational hours per year. The 18 new skylights provide an exceptional daylight performance, which is especially impressive considering the simultaneous requirements from a thermal/energy perspective





ASHRAE Headquarters - Net-Zero Energy Building Design

Over the last 30+ years, IES has built a solid reputation as the leading global innovator in integrated performance-based analysis for the built environment.

The IES Virtual Environment (IESVE) is a powerful, in-depth suite of building performance analysis tools. It enables the design and operation of low/zero carbon, healthy and comfortable buildings. Whether working on a new build or renovation project, IESVE allows designers to test different options, identify best passive solutions, compare low-carbon & renewable technologies, and draw conclusions on energy use, CO2 emissions, occupant comfort, and much more.
There are various applications in the suite; each designed to provide sustainable analysis at levels suitable for different design team members and design stages. All utilize our Apache dynamic thermal simulation engine, and an integrated central data model. 

Building Energy Modeling (BEM) with the IES Virtual Environment software is the perfect industry design tool for electrification and decarbonization of the built environment. Various design strategies are available with decarbonization as an end goal, such as: passive design, energy conservation, energy efficiency, electrification, incorporating renewable energy technology, or energy storage.

From optimizing room and zone loads to detailed HVAC system and equipment sizing, IESVE HVAC software offers the most practical, efficient, and accurate tools available. IESVE can quickly and easily undertake CIBSE & ASHRAE heating and cooling loads calculations, with efficient inputs for 3D geometry, envelope, internal gains, external design conditions and location. Minimum ventilation requirements can be included, or local code minimum ventilation can be utilized. Reports can be generated in either spreadsheet or PDF format, and can be shared to help gain insights from in-depth results analysis, or iterate on building design. These calculations transition seamlessly into detailed HVAC system sizing and optimization.

IESVE can also be utilized for quick and easy CFD airflow simulation. An existing IESVE model can be used for early stage CFD simulations, without needing to import further data or export into other tools. MicroFlo-CFD performs ‘snapshot’ CFD simulation by importing boundary conditions from APACHE’s dynamic simulation, or allows manual boundary conditions to be added. Ventilation from passive sources (e.g. operable windows) or mechanical devices (e.g. diffusers) can be included in these simulations. MicroFlo-CFD can be utilized for a range of CFD use cases, such as: passive natural ventilation design, passive atrium design, data center design, hospital operating room design, HVAC design for occupant thermal comfort, external wind studies, or normal use ventilation of car parks.

There is also the option within IESVE to utilize Parametric Simulation. This feature empowers users to compare a large range of design possibilities, be it for a single-variant design study or a multi-parameter whole-building design perspective. The Parametric Simulation feature has access to a large number of model variables and is integrated into the full range of APACHE’s links (Solar, Daylight, Airflow, Loads/Sizing and HVAC Systems). Over a thousand permutations are possible with one model. 

With the IESVE software, you can undertake daylighting for LEED and BREEAM, electric lighting design, glare prediction, daylight harvesting, daylight autonomy, user-specified visualizations. IESVE can ensure good natural daylight and visual comfort, reduce lighting gains, and test how your lighting designs will look and perform. Daylight, sunlight and overshadowing analysis can be carried out, with results generated for climate-based daylight modeling and daylight autonomy. For lighting design, daylight harvesting and dimming control assessments can also be undertaken. All of this combined can help you meet the requirements of local codes and best practice guides. 

Complex solar shading calculations can also be undertaken within IESVE, to determine how solar rays pass through both external and internal openings.  The path of the sun is tracked across rooms and atriums into internal space allowing the exact location and impact of solar gain to be understood. Internal and external solar shading devices can be tested, along with assessing the shading or right to light impact of surrounding buildings and terrain. Any solar shading calculations can then inform Loads Calculations and Energy Simulations. 

IES also offers unrivalled interoperability with other CAD design and analysis tools. The smooth and robust two-way information exchange between IESVE and BIM platforms speeds up the design process and facilitates digital design.
