2.2.1 PERFORMANCE TARGETS

Energy Benchmarks and Targets
PROJECT AND CITY GOALS
The 14 @ Irving development project will target energy
th
performance of a minimum of 25% better than the ASHRAE
90.1-2016 Energy Cost Budget (ECB) baseline and
approximately 30% better than the LEED-CS v2009 baseline,
in alignment with the direction of the upcoming NYC energy
Stretch Code. Additionally, the project team is investigating
the feasibility of achieving 30% emissions savings against the
ASHRAE 90.1-2016 Appendix G baseline, which will qualify
for NYSERDA PON3906 Deep Energy Savings support and
align with the New York City’s 80x50 goal and the current
AIA 2030 Challenge goal. Achieving this reach goal will
reduce greenhouse gas emissions by 440 mt CO2/year
compared to current code and 1,410 mt CO2/year compared
to a typical office building.
To achieve the reach goal, 14 @ Irving will target an energy
th
use intensity of 38 kBtu/sf/year or below. The project team
will follow an optimization pathway that first considers a
highly effective building envelope, then demand reduction,
and finally the selection of high-efficiency building systems
and fine-tuning of controls. Once energy efficiency
opportunities are maximized, on-site photovoltaic systems
will be evaluated to take advantage of all possible
opportunities.

Key opportunities include:
— Balancing heating and cooling load reduction strategies
— Optimizing the façade in response to site context
— Incorporating photovoltaics on the roof shading feature
— Improving glare management strategies to preserve
high-quality daylight and views
— Selecting a highly-controllable HVAC system which can
th
respond to site context-driven load differences Meeting 14 @ Iriving’s energy goals will align the building
— Aligning envelope, HVAC, and interior lighting and with the upcoming NYC Energy Stretch Code and the current
equipment strategies to maximize performance AIA 2030 goal.
— Separating ventilation and space cooling with high
efficiency VRF system and DOAS
