The results of the ASHRAE project I finished are described 
below. The final report package includes lots of EnergyPlus 
IDF files implementing the 30 measures examined as well as 
the scripts used to generate them with Eppy.

*New Research from ASHRAE Outlines Measures to Reach Toward 
Net Zero Energy*

ATLANTA – Application of 30 specific energy savings measures 
across all building types and climate zones resulted in 
cutting energy use by nearly half, according to results of 
newly approved research funded by ASHRAE.

The national weighted change is 47.8 percent more energy 
efficient than Standard 90.1-2013 based on site energy and 
47.8 percent more energy efficient than 90.1-2013 based 
source on energy.

The question of “how energy efficient can commercial and 
multifamily buildings become in the near future if first 
cost is not considered” was explored in ASHRAE 1651-Research 
Project, “Development of Maximum Technically Achievable 
Energy Targets for Commercial Buildings: Ultra-Low Energy 
Use Building Set.”

“The value of establishing such ultra-low-energy targets for 
buildings is two-fold,” Jason Glazer, principal engineer for 
GARD Analytics who oversaw the project, said. “These targets 
will indicate to building design professionals what may be 
achieved if first cost is not considered and challenge the 
creativity of those professionals to achieve similar results 
in actual designs with the real-world constraints of first 
costs. They also will help advance design guides, standards 
and codes by providing an ultimate goal.”

For the project, researchers assembled a list of energy 
efficiency measures that can be included in the design of 
non-residential buildings. The list included both commonly 
used and cutting edge energy efficiency measures, according 
to Glazer.

 From the resulting list of almost 400 measures, 30 were 
chosen for additional analysis. Sixteen prototype buildings 
that were consistent with Standard 90.1-2013, /Energy 
Efficiency Standard for Buildings Except Low-Rise 
Residential/, across 17 climate zones were used as baseline 
models. The 30 measures then were individually modeled. Each 
of the 30 measures, often with many options, were applied to 
each building and climate combination. In general, the 
measures were applied in the following order:

  *   Reduce internal loads
  *   Reduce building envelope loads
  *   Reduce HVAC distribution system losses
  *   Decrease HVAC equipment energy consumption
  *   Major HVAC reconfigurations.

“It is useful to understand how far energy efficiency 
measures can go to reduce the use of energy in the built 
environment,” Glazer said. “It is also important to 
understand that many of the measures used in the project are 
widely available today.”

After each measure was applied to each of the 272 building 
and climate combinations, if the energy consumption was 
reduced, it remained in the model. After all 30 measures 
were applied, the projected U.S. national weighted energy 
consumption for new buildings was nearly cut in half 
compared to Standard 90.1-2013.

The 30 energy efficiency measures modeled were:

  * LED Exterior Lighting
  * Highest Efficiency Office Equipment
  * High Performance Lighting (LED)
  * Shift from General to Task Illumination
  * Optimal Daylighting Control
  * Optimal Roof Insulation Level
  * Optimal Choice of Vertical Fenestration
  * External Light Shelves
  * Daylighting Control by Fixture
  * High Performance Fans
  * High Performance Ducts to Reduce Static Pressure
  * Demand Controlled Ventilation/CO2 Controls
  * Multiple-Zone VAV System Ventilation Optimization
  * Optimal Water/Air Cooling Coils
  * Occupant Sensors for Air Handling Equipment
  * Energy Recovery Ventilators
  * Indirect Evaporative Cooling
  * High Efficiency/Variable Speed Packaged DX Cooling
  * High Efficiency Heat Pumps
  * Ground Source Heat Pump
  * High Efficiency and Variable Speed Chillers
  * Heat Recovery from Chillers
  * High Efficiency Boilers
  * High Efficiency Building Transformers
  * Chilled/Cooled Beam
  * Dedicated Outside Air System with Heat Recovery
  * Underfloor Air Distribution
  * Hybrid/Mixed Mode Ventilation
  * Radiant Heating and Cooling and DOAS
  * Variable Refrigerant Flow Air Conditioning
