RFP #7-10

Request for Technical Expertise on Natural Gas Household Appliances in Argentina


The Collaborative Labeling and Appliance Standards Program (CLASP) is an international non-profit organization that promotes energy efficiency standards and labeling (EE S&L) for commonly used appliances and equipment. With support from the ClimateWorks Foundation, CLASP is undertaking efforts to ensure that the right experts are in the right places at the right times so that appropriate measures, including technical assistance and information exchange, lead to maximum CO2 savings. To that end, CLASP is funding technical analyses that support policy-makers at all levels involved in EE S&L and in key countries.

This RFP requests support by a technical expert for technical analyses, advice and training to the Argentine National Regulatory Agency for Natural Gas (ENARGAS) and its partners in the final stages of the development of energy efficiency labels and standards for natural gas instantaneous and storage water heaters.

The aim of the analysis is to provide ENARGAS and its partners with technical information, based on international best practice, in order to develop or improve energy efficiency standards that successfully balance technological feasibility, economic cost and energy savings, aiming at a significant reduction of CO2-emissions from the use of natural gas in the residential and commercial sectors.


The Government of the Argentine Republic is pursuing the National Energy Efficiency Standards and Labeling Program, as part of the National Program for Rational and Efficient Use of Energy (PRONUREE). Coordinated by the National Energy Secretariat, the program includes the development and implementation of energy efficiency labels and standards for electric appliances and equipment, including refrigerators and freezers, incandescent and fluorescent lamps, room air conditioners, three phase electrical motors and household washing machines.

Complementary to these activities, the Argentine National Regulatory Agency for Natural Gas (ENARGAS) is developing energy efficiency test procedures and labeling requirements for natural gas household appliances, including domestic cooking ranges and ovens, instantaneous and storage water heaters, room heaters, condensing boilers for water heating and hybrid solar-natural gas water heaters. ENARGAS has the legal authority to mandate both energy efficiency labeling requirements and minimum energy performance standards (MEPS) for natural gas equipment in Argentina. Energy efficiency standards and labeling requirements will be integral part of revised mandatory NAG-Standards ("Normas Argentinas de Gas"). NAG-Standards include both safety and minimum energy efficiency requirements of products. As a first step, ENARGAS has completed the draft labeling requirements for domestic cooking ranges and ovens, which are at the moment in public consultation (see here).

Currently, ENARGAS is working on energy efficiency test procedures and labeling requirements for instantaneous and storage gas water heaters. These activities include performance tests realized under an agreement with the National Institute for Industrial Technology (INTI), in accordance with test procedures developed for this purpose. Under another agreement, the National University San Martin (UNSAM) is analyzing the costs and benefits of an early replacement program for gas water heaters.

ENARGAS is also in the process of discussion of the labeling requirements of room heaters.

Analysis carried out by ENARGAS suggests that the Argentine buildings sector could save at least 10 – 14million m3 of natural gas per day. Regarding residential water heaters, ENARGAS estimates that the operation of pilot flames alone results in a natural gas consumption of 3.5 million m3 per day, equivalent to approximately 2 – 2.5 Mt CO2 emissions per year. According to the performance tests carried out so far, 25% of the energy consumption of a typical instanteneous water heater is due to the pilot flame.
All test results and studies carried out so far will be available for review by the expert.

Scope of Work

The objective of the technical assistance is to provide technical review and advice on the development of energy efficiency test procedures and labeling requirements for natural gas instantaneous and storage water heaters for the types of products currently sold in Argentina. It also includes training of staff of ENARGAS and ENARGAS’s partners (like universities and technological institutes), and the presentation and discussion of findings in workshops organized by ENARGAS.

The following tasks will be undertaken:

  1. Technical review and advice on the development of energy efficiency test procedures and labeling requirements for the following appliances, which are currently under investigation by ENARGAS:
    • Instantaneous Gas Water Heaters for household use (thermal capacity 14 – 23 kW)
    • Storage Gas Water Heaters for household use (thermal capacity 3 – 6.5 kW, storage capacity 50 – 250 liters)

Technical specifications of these appliances are presented in Annex 1.

Task 1 includes the following sub-tasks:

    1. Review, make comments and suggest improvements as appropriate of technical documentation provided by ENARGAS, including test procedures and labels requirements, as well as underlying market studies and technical and economic analysis;
    2. Review and comment on laboratory test procedures, definition of a usage cycle representative of actual conditions of use, and the definition of the energy efficiency label categories; and
    3. Propose criteria and guidelines for future analysis and the definition of thresholds for Minimum Energy Performance Standards (MEPS).
  1. Discuss preliminary findings of the review in a first workshop organized by ENARGAS (in November 2010); with ENARGAS's partners (like universities and technological institutes) and stakeholders (in particular with local manufacturers);
  2. Present and discuss the final results of the work in a second stakeholder workshop tentatively scheduled by ENARGAS for December 2010.

The scope of work will include two visits of the expert at approximately one week per visit. Each visit will include participation in the respective workshop as mentioned under tasks 2 and 3. In addition to the scope of work described in work items 1 - 3, the expert should be prepared to comment on specific questions concerning other domestic gas appliances included in the work program of ENARGAS.

The expert will complete and provide a report that documents the results and recommendations of each task, as mentioned above. The report will be in English or Spanish, and will include an executive summary in English.


The work shall be realized in November and December 2010, and is expected to require 25 person-days of expert time, including two visits of 5 working days each to Argentina.


A committee appointed by CLASP will evaluate qualifications received from respondents. Selection of qualified experts will be based upon the following criteria:

  • International reputation as a leading technical expert for natural gas appliances, in particular the selected products;
  • Experience working collaboratively with other experts in the realm of energy efficiency for the selected products, and in particular with CLASP;
  • Top-of-mind familiarity with product specific test procedures, energy efficiency labels and MEPS for gas appliances, in particular water heaters;
  • Familiarity with international technical standards for the selected products, in particular those standards referenced in NAG-313 (instantaneous water heaters) and NAG-314 (storage water heaters), which are partially based on EN standards (see here );
  • Familiarity with cost-benefit analysis methodology to define energy efficiency thresholds and label categories;
  • Special consideration will be given to technical experts who have prior experience in emerging economies, like Argentina, and with product designs common in the Argentine market;
  • Excellent knowledge of English; working knowledge of Spanish is an advantage.
