A brief description of when and why the building energy consumption baseline was adopted:
A brief description of any building temperature standards employed by the institution:
LIU Post installs automated electronic controls for heating and air conditioning systems when renovation work is done. This allows us to manage HVAC systems from a central location and operate them more efficiently. This results in a higher level of comfort for occupants with lower operating costs.
A brief description of any light emitting diode (LED) lighting employed by the institution:
The Department of Facilities Services at LIU Post has installed LED lighting technology in a few applications. Locations with LED lighting include aisle lighting and outdoor lighting along ramps and stairs in the Tilles Center as well as chandeliers and wall sconce lights in Lorber Hall and Bush Brown. Additionally, all incandescent light fixtures and bulbs in Hillwood Commons were replaced last December with LED fixtures/bulbs.
A brief description of any occupancy and/or vacancy sensors employed by the institution:
LIU Post uses photo cells for many outdoor lighting applications and dual technology (passive infrared/motion) for indoor lighting applications. About 25% of the building space on campus is equipped with this technology.
A brief description of any passive solar heating employed by the institution:
N/A
A brief description of any ground-source heat pumps employed by the institution:
In 2007, LIU Post installed a new geothermal central air conditioning system, designed to retrofit the Winnick House administration center. This geothermal system provides air conditioning only. It always provides ground water for condenser cooling for both Mullarkey Hall and Winnick House. However, when temperatures are milder the ground water temperature is cool enough to provide proper air conditioning for Winnick House only.
A brief description of any cogeneration technologies employed by the institution:
N/A
A brief description of any building recommissioning or retrofit program employed by the institution:
In 2013, LIU Post completed a large lighting retrofit project where all T-12 fixtures on campus were replaced with more efficient T-8 fixtures. In 2002, the Pratt Recreation Center was commissioned and in 2008 it was recommissioned and had several of its HVAC systems looked at for improved efficiency.
A brief description of any energy metering and management systems employed by the institution:
LIU Post meters all buildings in some way. Some are metered individually and some are metered as a group. LIU Post uses a building management system that controls all equipment. However, it does not track energy consumption in real time. Instead, our energy consumption is tracked by reading meters and then entering that data as well as the data from all of our bills into a spreadsheet.
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
All appliances at LIU Post are replaced with higher efficiency alternatives during renovations or when equipment breaks down beyond reasonable costs of repair.
A brief description of any energy-efficient landscape design initiatives employed by the institution:
N/A
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
All vending machines at LIU Post are equipped with motion sensors that inform our vendor when a product has been sold. It is part of an inventory system that allows them to monitor product movement remotely.
A brief description of other energy conservation and efficiency initiatives employed by the institution:
