The LOK Family of Solutions can help your new facility earn points toward LEED Certification

The LEED green building rating system evaluates environmental performance from a whole-building perspective. It examines and awards points in the areas of site sustainability, water efficiency, energy & atmosphere, materials & resources, indoor environmental quality, innovation in design and regional priority credits. A total of 110 points are available for new construction.

Prerequisite 2 – Minimum Energy Performance Required

This required prerequisite is to establish the minimum level of energy efficiency for the proposed building and systems to reduce environmental and economic impacts associated with excessive energy use.

The LOK Family of Solutions reduce energy consumption and improve Power Usage Effectiveness (PUE) to assist in achieving this prerequisite.

  • KoldLok Grommets contribute to earning points in this credit by preventing costly bypass airflow – conditioned air that escapes through unsealed cable openings. This reduces waste and results in more efficient use of cold air and decreased energy consumption.
  • HotLok Blanking Panels prevent the circulation of hot exhaust air from the back of the cabinet to air intakes in the front. Installing HotLok blanking panels immediately reduces the intake air temperature of servers when exhaust air circulation is present and enables higher temperature set-points for cooling equipment. This results in significantly lower energy consumption immediately and over time.
  • AisleLok Partial Containment Products prevent errant airflow in the aisle. Installing AisleLok sealing solutions increases efficiency, capacity and system reliability. Steering hot exhaust air away from bypass airflow vulnerabilities and towards safer return airflow channels further improves efficiencies by doubling or tripling power density limits in otherwise underperforming data centers.
  • EnergyLok Services identify computer room inefficiencies and offer targeted remediation strategies that immediately reduce operating costs, deliver a quick pay back, allow you to plan for increasing server density and significantly reduce your CO2 contributions.

Credit 1 – Optimize Energy Performance (19 Possible Points)

The intent of this credit is to achieve increasing levels of energy performance beyond the prerequisite standard to reduce environmental and economic impacts associated with excessive energy use. To earn points in this credit, LEED applicants must demonstrate a percentage improvement in the proposed building performance rating compared with the baseline building performance rating according to Appendix G of ASHRAE Standard 90.1-2007.


The American Society for Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) publishes “Thermal Guidelines for Data Processing Environments” (TC 9.9). This document is meant to align the industry on the environmental requirements of IT equipment and the conditions required in a data center to support high-availability. The most important location to monitor environmental conditions in a data center is at the air intake of IT equipment, so ASHRAE publishes recommended temperature ranges for intake air.

  • KoldLok Grommets increase the conditioned air output through perforated tiles to bring IT equipment intake air temperatures within ASHRAE recommended guidelines.
  • HotLok Blanking Panels seal the cabinet to immediately reduce the circulation of hot exhaust air and reduce IT equipment intake air temperatures to achieve ASHRAE guidelines.
  • AisleLok Partial Containment Products greatly reduce costly bypass airflow, increasing usable cooling unit capacity, and ensuring maximized efficiency from HVAC equipment and compliance with ASHRAE guidelines.
  • EnergyLok Services optimize current airflow infrastructure to increase cooling capacity and IT density, enable precision cooling to reduce or eliminate hotspots, dramatically reduces costly bypass airflow, support data center best practices and ASHRAE compliance.
