Clarifying ASHRAE's Recommended Vs. Allowable Temperature Envelopes and How t...Upsite Technologies
The topic of raising temperatures in data centers used to be met with much criticism in the industry, but in recent years has become more accepted. A big driver for this acceptance has been ASHRAE’s expanded envelope for recommended and allowable server inlet temperatures. However, while this has eased the discussion, there are still some questions that have been left unanswered. What’s the difference between recommended and allowable? Which one is best to use? What steps must be taken to safely raise set points? How do you ensure servers are still adequately cooled? What if you have different server types (A1, A2, A3, A4)? This presentation will examine these questions to give a clearer understanding of ASHRAE’s recommended and allowable guidelines. Also covered will be an explanation on how, in some cases, it is possible to raise cooling control set points without raising server inlet temperatures.

Study of data centers reveals the average computer room has cooling capacity that is nearly four times the IT heat load. When running cooling capacity is excessively over-implemented, then potentially large operating cost reductions are possible by turning off cooling units and/or reducing fan speeds for units with variable frequency drives (VFD). Using data from 45 sites reviewed by Upsite Technologies, this presentation will show how you can calculate, benchmark, interpret, and benefit from a simple and practical metric called the Cooling Capacity Factor (CCF). Calculating the CCF is the quickest and easiest way to determine cooling infrastructure utilization and potential gains to be realized by AFM improvements.

For Most Data Centers, Liquid and Air Cooling Will Not be Mutually ExclusiveUpsite Technologies
A recent report from Technavio indicates that the adoption of liquid-based cooling is high, as it is considered more efficient than air-based cooling. Globally liquid-based cooling is expected to grow at a remarkable rate through 2020, posting a CAGR of almost 16% during the forecast period. So, why is this level of adoption happening? Increasing rack densities lead by high performance computing (HPC) and the quest to improve efficiency are driving an increase in liquid cooling design strategies and deployment. While still relatively sparse, liquid cooling will become more prevalent, but this does not mean the end of air cooling. In this session, we’ll discuss how to implement liquid cooling while maintaining appropriate air-cooling conditions and fully realize efficiency gains. Lastly, we’ll discuss how to get started and get ahead of the market when it comes to improving cooling efficiency.

Pervasive Computing Based Intelligent Energy Conservation SystemEswar Publications
Most of the HVAC system in home is running based on static control algorithm; based on fixed work schedules. In that old system energy became waste when home contains low or no people occupancy. In this paper we presented new dynamic approach of HVAC system control, by combined with pervasive computing. Pervasive computing can be defined as availability of centralized system and information anywhere and anytime. We achieved our target by using occupancy sensors for collecting home status. Initially our occupancy sensors collect human presence and current HVAC status details and stored in centralized system. Then based on our user defined threshold value the centralized system maintains the building's heating, cooling and air quality conditions by controlling HVAC devices. I.e. this system turned off HVAC systems when a home is unoccupied, or put the system into an energy saving sleep mode when persons are asleep.

Workshop On Risk Assesment by Palash Ch DasPalash Das
Risk management principles are effectively utilized in many areas of business and government including finance, insurance, occupational safety, public health, pharmacovigilance, and by agencies regulating these industries. Although there are some examples of the use of quality risk management in the pharmaceutical industry today, they are limited and do not represent the full contributions that risk management has to offer. In addition, the importance of quality systems has been recognized in the pharmaceutical industry and it is becoming evident that quality risk management is a valuable component of an effective quality system.
Certifying is often mistakenly referred to as commissioning. In many cases, owners will purchase commissioning, but receive certifying services. It is important to know what you’re paying for. Project goals and budget typically determine which service is needed. If public recognition, such as LEED, is desired to illustrate that a building is sustainable and meets specific environmental goals, then certification is necessary. On the other hand, if the project goal is to ensure optimal building performance, then commissioning is the preferred choice.

Fuzzy based control using labview for miso temperature processeSAT Journals
Abstract This project aims at designing and implementing a fuzzy controller for Multiple Input Single Output temperature process. Temperature control of water in the tank is achieved by varying current to the heating rod and inlet flow rate by a fuzzy controller. The system consists of a tank, reservoir, variable speed pump, temperature sensor placed inside a heating tank containing the heating rod, voltage controlled current source and computer. Water is pumped into the tank from reservoir and RTD measures the current temperature. The signal from the temperature sensor is sent to the DAQ interfaced to the computer. LabVIEW software is used to acquire the input signal and send the output signal that is determined by the control algorithm. Fuzzy logic controller is designed in LabVIEW. Based on the set point temperature, the controller sets the appropriate current to the heating rod. If the required temperature is less than that sensed by the temperature sensor, the flow rate of water into the tank is controlled by a variable speed pump. While conventional controllers are analytically described by a set of equations, the FLC is described by a knowledge-based algorithm. Thus this system is highly efficient in both heating and reducing the temperature of the tank. A fuzzy logic controller gives faster response, is more reliable and recovers quickly from system upsets. It also works well to uncertainties in the process variables and it does not require mathematical modelling.

In this thesis we have proposed an HVAC system, which we have carefully selected and designed for
an IT company, based on the blueprint which was provided. Our approach was to calculate the Heat Load of the
whole floor which was dedicated for the IT company. We tried to closely observe every aspect of the floor or the
company which can have an impact on our heat load calculation. The floor level, windows, number of rooms,
partitions, the specific work has to be done in that compartment, the level of radiation, electronics, gadgets,
sunlight entering from the windows, the time and duration of the outside heat and many more important factors
we took into consideration. Based on our calculation we had to provide the best efficient system which can fulfill
the needs and can assure the better Indoor Air Quality (IAQ) and human comfort. The system which we selected
for this particular IT company was VAV. Variable air volume (VAV) is a type of heating, ventilating, and airconditioning (HVAC) system, this VAV systems vary the airflow at a constant temperature.
75F Outside Air Optimization and Economizer ControlBrendonMartin3
75F Outside Air Optimization (OAO) combines hardware, software, and real-time weather data to provide advanced operation sequences for rooftop economizers to built-up air handlers in a variety of commercial buildings. This application has three main advantages: it improves energy efficiency, reduces comfort complaints, and improves ventilation and indoor air quality in high traffic areas.
HVAC is typically responsible for around 40% of the energy consumption in a building. Frequently, this is the largest energy consuming type of equipment on a site and can therefore provide significant scope for saving energy and money. This fact sheet covers common types of HVAC and will guide you in the right direction to identify energy efficient HVAC initiatives.

20. Room 2213 is an example that can be repeated for all but 2 labs. There are multiple zones overlapping and fighting each other. This issue has been occurring since the building was built. Air delivery rates in 2213 are far from balanced. The zones are totally independent. Simultaneous heating and cooling
21. The re-zoned lab Eliminated the thermostats fighting each other. Created a balanced air delivery throughout the lab.
26. What does energy savings look like? Using the CDCV system we can see room, time, and CFM savings. UC Irvine not only uses the system as an MBCx tool but we validate our savings as well
This CDCV system begins with: room sensors to measure the quality of the air in many locations of a building An air router pulls the air sample to the Sensor suite that analyzes the air sample for… An information management server tells the VAV controller to increase or decrease air flow All this data is logged into a computer for analysis
