ABSTRACT

The objective of this survey was to gather baseline information in preparation for a technical and

financial feasibility study for promoting efficient air conditioners or replacing inefficient air conditioning

units with more efficient ones among government buildings. Air con inventory and utilization

questionnaires were sent to 120 government agencies and government-owned corporations, of which

54 responded. The survey counted a total of 4,473 air con units installed within the buildings of the 54

respondents. The units were practically evenly divided between window type and split type units.

Centralized air cons comprised only 1% of the total air conditioners. Majority of window type units had

cooling capacities of 18,900-19,000 kJ/h, while units with 60,000 kJ/h cooling capacities are the most

predominant among split type units. Of the total, some 2,040 units included information on their

operating age. More than one-third (39%) of these had been operating for at least 10 years. A close look

at the correlation between age and energy efficiency ratios (EER) suggested that units that are more

than 10 years old do not necessarily have low EER values. In fact, some air cons that are more than 10

years old have very high EERs. Majority (79%) of air cons that reported their EERs were above the new

minimum energy performance standards, or equivalent to 1-star rating, by the Philippine National

Standards. In fact, most had 4-star rating. Replacing all air cons that do not comply with the MEPs with

air cons that have higher EER values have a potential total monthly electricity savings of Php 693,000

(USD16,500) to PhP 981,000 (USD23,360), with paybacks ranging from a high of 30 months to a low of

eight months. In fact, replacing with higher EER air cons significantly reduces the payback period.

1.0 Introduction

This survey was conducted to gather baseline information on air conditioning utilization among

government buildings in Metro Manila in preparation for an investigation on the technical and

financial feasibility of switching to more efficient air conditioning units or air cons. Air cons inventoryand use questionnaires, which benefitted from the comments and inputs of the United Nations

Environment Programme (UNEP), were sent by the Department of Energy (DOE) to 120 government

agencies. 54 agencies had responded to the survey, and their responses formed the basis of the

present study. The study is of course limited by the quantity and quality of information provided by

the respondents. Many respondents did provide a good quantity of quality data. Nevertheless, data

collected for selected agencies were validated through the ensuing field visits and inspection. The

DOE and International Copper Association South East Asia (ICASEA), with assistance from

CleanEnergy Solutions International (CSI), visited and validated the responses of the Philippine

Health Insurance Corporation, Local Water Utilities Administration, Securities and Exchange

Commission, National Housing Authority, and Department of Public Works and Highways. Indeed,

the visits provided more and better insights on air conditioning utilization among government

buildings. This report was prepared by CSI on behalf of DOE and ICASEA.

2.0 Respondents

The air cons inventory questionnaires were sent to 120 government agencies. 54 responded and are

listed and classified in Table 1. Majority of the respondents (19) are government agencies or

bureaus either directly supervised by the Office of the President or by different government

departments. On the other hand, 16 are Government Owned and Controlled Corporations (GOCCs),

one of which is a development bank. Nine are government executive departments that provided air

con data on their main offices, along with two field or satellite offices. Five are research entities, of

which three are under the Department of Science and Technology, one supervised by the

Department of Agriculture, and one under the Department of Finance. Four of the respondents are

regulatory bodies (Toll Regulatory Board, Games and Amusements Board, Insurance Commission,

and Dangerous Drugs Board). The government-owned television network, People’s Television

Network, also participated in this study.

3.0 Number of Air Conditioners

A total of 4,473 air conditioners have been reported by the respondents. These consist of window

type units, split type units and centralized air conditioners. Figure 1 shows the breakdown of air con

types. The tally for split type air cons includes both floor standing and wall mounted split units. Thereported air cons are almost equally divided into window and split type units, with centralized units

comprising just a mere 1% of all air cons.

Figure 1: Breakdown of Air Conditioners Types

Among all the respondents, the Department of Public Works and Highways (DPWH) has the highest

number of air conditioners with a total of 662 window and split type units. Following the DPWH are

the Department of Energy (245 air cons) and Department of Science and Technology – Industrial

Development Technology Institute (244 air cons). Table 2 lists the top 10 respondents with the

highest number of operating air conditioners. The units of these 10 agencies comprise 52% of the

total air cons in this study. The complete ranking of all respondents is in Annex 1.

3.2 Split Type Air Conditioners

The split type air conditioner comprises of an indoor unit and an outdoor unit. The outdoor unit

houses the compressor and condenser, while the indoor unit encloses the evaporator coil and

cooling fan. Split type units do not require mounting through walls. It only needs a small hole for the

conduit that connects the indoor and outdoor units. The indoor units of split type air cons may be

wall-mounted or floor-standing.

The Department of Public Works and Highways also has the most number of split type air

conditioners with 304 units. The Philippine Ports Authority follows with 207 split type units, which

are all its air cons. These split type units include both wall-mounted and floor standing split units.

Centralized Air Conditioners

The centralized air conditioning system uses ducts to distribute cooled air, or pipes to distributechilled water to heat exchangers to multiple rooms. Among the 54 respondents, 10 use centralized

air conditioners. Agencies that do not own the centralized air cons they use such as those that lease

space in the buildings they are in are not included in this tally. The complete list of respondents with

operational centralized air conditioners is in Table 5.

4.0 Air Conditioner Capacities

The succeeding graphs (Figure 2 -

Figure 4) show the breakdown of air con units according to their cooling capacities. Among window

type air cons, units with cooling capacities 18,900 – 19,000 kJ/h are the predominant (totaling 573

units). In the market, these units are more commonly referred to as 2HP units (although there is no

equivalence between the HP and kJ/h ratings). These make up 25% of all window type units

reported.

The 60,000 kJ/h (5 Tons) units are the most commonly used split type air cons (totaling 697 units),

followed very closely by the 36,000 kJ/h (3 Tons) units (612 units). The combined total of air cons

with these two cooling capacities constitutes 60% of all split type units. For centralized air cons, the

most commonly used are the 10 Tons and 140 Tons units (which both total eight units).

5.0 Age of Air Conditioners

Out of the total 4,473 air con units in this survey, some 2,040 units (46%) have been indicated the

number of years they had been operating. The age of each unit was calculated from the year it was

purchased. It was assumed that the units had been operating since their purchase date. The oldestreported unit is a window type air conditioner installed at the Department of Science and

Technology’s central office, which has been operating for 27 years. Majority (39%) of the air cons

have been operating for 10 years or longer. Figure 5 shows the breakdown of these air cons

according to their ages.

Figure 5: Operating Ages of Air Conditioners

Majority of the units operating for more than 10 years are window type air conditioners. Of the 38

centralized units reported, 12 units had been operating for more than ten years. Figure 6 shows the

types of air conditioners aged 10 years or longer.

Sizing of Air Conditioners

As a general guide for choosing the proper size of air conditioner to cool a room, the Department of

Energy prescribes a cooling capacity of 500 kJ/sq m. This value does not take into account the

number of persons occupying the room nor the shading or sunlight the room receives. For this

study, units with cooling capacities 500 – 550 kJ/sq m are the ones considered properly sized. If a

unit has a cooling capacity below 500 kJ/sq m then it may be considered ‘undersized.’ Air

conditioners that have small cooling capacities or are undersized will continually run to keep up with

cooling a large room. The unit will not efficiently cool the room and will result to higher electricity

bills. Air cons with cooling capacities greater than 550 kJ/sq m are considered ‘oversized.’ These airconditioners will cycle on and off frequently. The efficiency of the typical air conditioner increases

the longer they run. Moreover, air cons that run on longer cycles are more effective in removing

moisture. For short cycles, the evaporating coils do not have enough time to operate at the low

temperature and when the unit stops, the moisture on the coils evaporates back into the indoor air

rather than be removed out of the condensate drain.1

Out of the 54 respondents, 39 indicated the floor area of the rooms cooled by each of their air

conditioners. The cooling capacities per floor area of 2,570 units (57% of total air cons) were

calculated. Table 7 shows the number of units grouped according to the indicated kJ/sq m capacity

ranges.

The table shows that only 6% of the reported air cons are actually properly sized. More than half

(57%) of the units are oversized with 15% operating at double that of the prescribed 500 kJ/sq m.

On the other hand, the main office of the Department of Social Welfare and Development has the

most undersized air cons with 169 units or 87% of its total installed air conditioners. Sixteen (16) out

The Department of Trade and Industry and the Department of Energy has completed the

implementing guidelines for the new standard on Energy Efficiency Ratio and labeling of air

conditioners (PNS 396 Part 1:2007) that establishes star ratings for window and split type air

conditioning units2. (The new standard did not set star ratings for package type and centralized air

conditioners.) Star ratings, moreover, are limited to room air conditioners with cooling capacities

equal to or below 36,000 kJ/h.3 A unit’s star rating depends on its energy efficiency ratio. The

Energy Efficiency Ratio (EER) is defined as:

Equation 1. Energy Efficiency Ratio

The succeeding tables (Table 12,

Table 13,

Table 14) show the number of air conditioning units in the survey per star rating. Out of the 2,232

window type units, the EERs of 727 units (33%) were reported or calculated. For split type units, theEERs of 961 (44%) of the 2,203 units were reported or calculated. These actually include units with

cooling capacities greater than 36,000 kJ/h. For these units, the star ratings of split type units 12,000

– 36,000 kJ/h were used.

2 The implementing guidelines was completed in 2011 and is pending announcement.

3 This is because of the limitation in the capacity of the testing laboratory.

21% (353 units) have EER values below the required minimum “1” star level. The potential electricity

savings generated by replacing these air cons with “0” star rating with air cons that have higher EER

values will be discussed in a later section.

The charts above (Figure 7) show the correlation between age and EERs of the air con units. Both

plots for window and split air conditioners exhibit that units 10 years old and above do not

necessarily have low EER values. In fact, the graphs clearly show that many units that were

purchased more than 10 years ago have EER values that are already higher than the current

minimum standard.

Both charts also suggest that that there is a wide spread in EER values for units with lower cooling

capacities (> 12,000 kJ/Hr). But as the cooling capacities increase, the EER values tend to be higher.

8.0 Number of Hours in Operation

The average number of operating hours for all air conditioners is 8 hours per day. However, the

average operating hours of all air conditioners of the Power Sector Assets and Liabilities

Management Office is 16 hours, and it has several units operating for 24 hours. Some other agencies

whose average operating hours is 10 hours are (1) Department of Science and Technology – CentralOffice, (2) Philippine National Oil Company, (3) People’s Television Network, and (4) National Kidney

Transplant Institute.

The monthly electricity costs of operating air conditioners with “0” star rating were calculated using

the following equation:

Equation 2. Monthly Electricity Cost per Aircon

The power input (kW) was either provided by the respondent or calculated from the EER using

Equation 1 . As the air cons have different power input or wattage values, the monthly electricity

cost for each air con was calculated. These were then summed up to get the total monthly electricity

costs for each case. Below are the other input values used:

Hours/day 8 Hours/ day The survey results showed that the average

operating hours for all air cons is 8 hours/day.

Days/month 22 days/month The number of work days in a month.Electricity

Price/kWh

PhP 10.00/kWh The unit cost of electricity charged to

government agencies.

For each case and scenario, air con units with “0” star rating will be replaced with units of higher EER

values. This implies shifting to air cons with lower wattage requirements. The new wattage values

were calculated using Equation 1. The new monthly cost was then calculated using the obtained




19

lower wattage values. The difference between the two electricity costs is the savings generated

from the switch. Below is an example of a Case 1 air con under Scenario 1:

The cost of replacing “0” star air cons with more efficient ones was calculated using 2008 air con

prices derived from an ICASEA-commissioned study.4 It was assumed that air cons will be replaced

with units of the same cooling capacity but higher EER. The prices used are shown below.

All cases demonstrate a direct correlation between EER values and energy cost savings. Shifting to

air cons with higher EER values will generate greater savings in electricity costs. Moreover, the

savings generated significantly outweighs the cost of replacement. This is shown in Figure 8, where

the payback period decreases with higher EERs (Scenario 1 vs Scenario 2) despite higher cost of air

con replacement.

Figure 9: Energy Cost and Savings per Air Conditioner*

*C = Current Scenario, S1 = Scenario 1, S2 = Scenario 2

Table 18 shows the monthly energy cost savings per air con in each case and scenario. Thesuggested EERs for Scenario 1 in all cases are the (minimum) EER values for the 1-star rating defined

by the Philippine National Standards for air conditioners. Switching to air cons with the minimum 1-

star EER value will already generate substantial energy savings ranging from Php 637 to Php 6,092

per unit. This redounds to annual savings of a minimum of PhP 7,644 to Php 73,104 per unit.

Switching to air conditioners with higher EER values (Scenario 2) will generate even greater annual

savings from Php 10,824 to Php 95,424 per unit.




22

Figure 9 compares the average electricity costs and savings in each scenario. It clearly shows that

the energy cost decreases with higher EER values (shifting from Current Scenario to Scenario 1 to

Scenario 2), which results to greater savings in electricity bill. The figure also suggests that greater

savings are generated in air conditioners of higher cooling capacities (Case 2 for window type and

Case 5 for split type).

10.0 Summary of Results

Air conditioner inventory and utilization questionnaires were sent to 120 government agencies and

received 54 responses in return. A summary of the results of this survey is outlined below:

There are a total of 4,473 air conditioner units reported by the respondents.

Half of the air conditioners are window type units and the other half are split type units.Centralized air cons comprise a mere 1% of all units.

The Department of Public Works and Highways (DPWH) has the highest number of air

conditioners, with 662 units. It also owns the most window type units and the most split

type units.

The National Electrification Administration (NEA) owns the most centralized air conditioners

with 8 units.

25% of all window type units have cooling capacities within the range of 18,900 –19,000

kJ/h.

60% of split type units have cooling capacities 60,000 kJ/h or 36,000 kJ/h.

The most commonly used centralized air conditioners are the 6 tons and 140 tons with 8

units each.

More than one-third or 39% of all air cons that reported their age have been operating for

10 years or longer.

57% of air conditioners with cooling capacity per floor area values are oversized having

cooling capacities greater than 550 kJ/sq m.

Majority (79%) of air conditioners that provided their EER values comply with the minimum

“1” star rating mandated by the new Philippine National Standards.

A big part (22%) of air cons with EER values have “4” star rating, while 21% (353 units) have

no star rating or below the minimum PNS required level.

Shifting all “0” star rating air cons to the minimum “1” star level generates a total of

Php693,091 monthly electricity savings, and could reach a total of PhP981,318 monthly if

replaced by units with higher EER values.

Savings generated from shifting to units with higher EER values outweigh the cost of air con

replacement. Payback of cost of replacing air conditioners decrease when shifting to higher

EER values.
