CDCS Environmental Monitoring & Sustainability 2

Question 1

What does LEED certification measure when applied to data center facilities?

Accepted Answer

Overall environmental sustainability including energy, water, materials, and indoor environmental quality

Answer

Power distribution unit efficiency ratings and UPS performance benchmarks

Answer

Network latency, bandwidth efficiency, and data throughput optimization

Answer

Physical security, access control, and compliance with safety standards

Question 2

What is 'free cooling' in the context of data center sustainability?

Accepted Answer

Using outside air or water when ambient conditions allow, reducing reliance on mechanical refrigeration

Answer

Installing solar panels to power cooling systems at zero ongoing operational cost

Answer

Recycling waste heat from servers to warm adjacent office spaces free of charge

Answer

Eliminating all active cooling infrastructure by deploying highly efficient low-power processors

Question 3

What is a Renewable Energy Certificate (REC) and how is it used in data center sustainability programs?

Accepted Answer

A tradeable certificate representing 1 MWh of renewable electricity generated, used to claim renewable energy usage

Answer

A government certification that a specific data center is powered exclusively by on-site solar generation

Answer

An audit document proving a data center has reduced its carbon emissions by at least 50% year-over-year

Answer

A direct power purchase contract signed between a data center and a specific wind farm operator

Question 4

What primary U.S. regulatory framework governs disposal of electronic waste from data centers?

Accepted Answer

Resource Conservation and Recovery Act (RCRA) for hazardous materials, combined with state-level e-waste laws

Answer

The Clean Air Act, which regulates all electronic component emissions and off-gassing

Answer

NFPA 75, which mandates specific disposal procedures for fire-protected IT equipment

Answer

ISO 14001, which requires certified recyclers for all IT asset retirement processes

Question 5

How does thermal energy storage (TES) contribute to data center sustainability?

Accepted Answer

Stores cooling capacity during off-peak hours to reduce peak demand charges and enable load shifting

Answer

Captures server waste heat to generate electricity through thermoelectric generator arrays

Answer

Stores solar energy as heat for use in powering cooling systems during peak daytime temperatures

Answer

Eliminates the need for uninterruptible power supplies during normal cooling operations

Question 6

What does the ERE (Energy Reuse Effectiveness) metric measure in a data center?

Accepted Answer

The ratio of total energy minus reused energy to IT equipment energy, crediting exported useful heat

Answer

The percentage of total energy sourced from renewable generation within the data center campus

Answer

Total cooling system energy consumption divided by server-level power consumption

Answer

The efficiency of energy recovered from UPS systems during discharge and recharge cycles

Question 7

What is the primary focus of ISO 50001 as applied to data center operations?

Accepted Answer

Establishing an energy management system framework to continually improve energy performance

Answer

Setting maximum PUE thresholds that ISO-certified data centers must not exceed

Answer

Defining cooling system design standards for Tier I through Tier IV classification

Answer

Mandating the use of renewable energy sources for all ISO-certified data center facilities
