3. LEADING TECHNIQUES FOR ENERGY SAVINGS IN COMMERCIAL OFFICE BUILDINGS

Fundamental Control Applications

This is the starting point for the building owner who wants to move beyond programmable

thermostats or sensor-activated lighting controls. Techniques for fundamental control include:

Zone Scheduling

Permits defined sections of a building to have HVAC and lighting reduced or shut down on aschedule. Zone scheduling means that a whole building does not need to run at a 100% comfort

setting if on only a few occupants are in the facility.

Night/Unoccupied Setback

Changes the comfort settings (setpoints) of HVAC so that space temperature decreases in

winter and increases in summer, thereby reducing demand for heating and cooling during

unoccupied hours. This feature can also be done using a programmable thermostat, but with only a

few schedules and no flexibility to more aggressively change setback temperatures.

After-Hours Override

Allows temporary changes to comfort settings after-hours. This eliminates the need to modifyschedules, which can sometimes become permanent by accident. This also avoids having the entire

building run in occupied mode to meet the needs of a small group.

Occupancy Sensors

Detect motion or infrared signatures in the space, and trigger lights or HVAC accordingly. The BAS

also enables scheduled overrides or triggers based on card access to an area of the building.

Holiday Scheduling

A calendar defines HVAC and lighting control for an entire calendar year, saving staff time

implementing special schedules and ensuring holiday weekdays do not run in occupied mode

Advanced Control Applications

In most cases, the same BAS put in place for fundamental controls is also capable of more advanced

control applications, often with only software changes. Techniques for advanced control include:

Follow Sunrise & Sunset

Permits lighting schedules (such as parking lots, signs, and outdoor access lighting) to vary

throughout the year as the length of daylight changes. This prevents lights from being on during thedaytime. The BAS automatically computes sunrise and sunset based on the latitude and longitude of

the buildings location.

Daylight Harvesting

In zones of the building near exterior walls and windows, lighting can be dimmed or shut off based

on specified minimum lighting levels detected by photocells. Controlled use of motorized shades can

also optimize the availability of natural light without compromising energy efficiency.

Optimum Start

Starts HVAC equipment only as early as required to bring the building setpoints to comfort levels

for occupancy. Control routines take into account outside air temperature and inside spacetemperatures when initiating the morning warm-up or cool-down cycles. Optimum start takes the

guess-work out of scheduled startup

Optimum Stop

Determines the earliest possible time to initiate setback temperatures before unoccupied periods

while still maintaining occupant comfort. Also known as coasting. Space temperature drifts

gradually beyond comfort levels in anticipation of the unoccupied period.

Ventilation On Demand

CO2levels in the occupied space are used as an indicator of the number of occupants in a room.

Calculations are then performed that relate the CO2level to the fresh air intake damper, indicating

when more outdoor air is needed. CO2levels also assist heating and cooling anticipation in

thermostatic control to optimize comfort and air circulation.

Variable Air Volume (VAV) Supply Air Temperature Reset

The supply air temperature (SAT) of variable volume air handlers can be reset upwards when full

cooling is not required. The SAT setpoint is increased on cooler days based upon the actual building

load. Then when terminal boxes reach 100% open, the SAT is decreased. This minimizes the need for

mechanical cooling, optimizes the use of economizers, and improves tenant comfort by reducing

drafts due to the movement of excessively cold air.


12/26


For





Demand Limiting or Load Shedding

Monitors electric meters and current draw on high-demand equipment, then relaxes setpoints to

immediately reduce demand. This technique can, for example, prevent a chiller from further loading,

but can also globally change setpoints throughout the building to shed electric load to avoid peak

utility charges. Non-critical equipment and lighting loads can also be shut off. Discussion and

planning usually occur with the customer in advance so the right strategies are implemented that fit

the business.

Chiller Optimization

The chilled water loop temperature can be raised as the cooling requirements for the building are

reduced, increasing chiller efficiency. A technique known as load reset raises the chilled water

temperature setpoint until one of the chilled water valves is 100% open.

Cooling Tower Optimization

The condenser water supply to the chiller can be decreased to a minimum setpoint, as defined by

the manufacturer. Then an optimal water supply setpoint can be calculated using a combination of

the outside air wet-bulb temperature and the cooling tower approach temperature. The reduced

water temperature improves the chillers partial load efficiency and also optimizes the coolingtowers operation.

Hot Water Reset

Hot water system temperatures can be reset based on outside air temperature, decreasing heat

losses in supply piping. This saves energy and also makes the office space more comfortable because

it reduces localized heating caused by excessively hot pipes.

4. Process Mapping (PM) for Energy

4.1 Objectives

To identify the type of energy that has been use in EAC

To identify how energy has been used in EAC

To specify critical parameters related to product quality and energyconsumption for each EAC

To identify documents needed for controlling of energy consumption in each

EAC

4.2 Development of PM

Process Mapping sheet below is customized for use in every EAC. Since there is no sub

metering was provided for each EAC, therefore energy input cannot be objectively

determined for each EAC. As such a cumulative energy consumption and EEI status shall

be provided in Energy Report to Top Management. However sub metering will be

proposed in Energy Committee for approval as part of Energy Conservative Measures.

4.3 Work Instruction (WI) and Log Sheet (LS)

Work Instruction in the following page shows the inspection process to be conducted on

all the process listed and monitoring of the controlling value. The data will be collected

using a range of equipment such as flow meter, temperature meter, lux meter as well as

other means of data collection that is available. Log sheet is also provided for the

inspectors to fill in actual data of all control parameters based on the frequency stated

in work instruction. Inspectors shall be appointed by Energy Committee.
