AN ACT 
PROMOTING THE DEVELOPMENT AND UTILIZATION OF SOLAR ENERGY IN 
ALL GOVERNMENT BUILDINGS AND OFFICES, PROVIDING FUNDS 
THEREFOR, AND FOR OTHER PURPOSES 
EXPLANATORY NOTE 
Certain legislation in the Philippines demonstrates a commitment to a 
sustainable future, notably Republic Act No. 11285, known as the “Energy Efficiency 
and Conservation Act”, which promotes the responsible use of energy technologies; 
and Republic Act No. 9513, the “Renewable Energy Act of 2008”, which establishes 
a framework for renewable energy development. 
Aligned with these laws, the Inter-Agency Energy Efficiency and Conservation 
Committee (IAEECC)  issued Resolution No. 8, s. 2023, urging government entities 
1
to incorporate solar photovoltaic systems or any equivalent renewable energy 
technologies into their electricity supply. The Department of Energy (DOE) has 
already initiated solar demonstration projects for government offices, including the 
National Economic and Development Authority (NEDA) Region 9 Office in Pagadian 
City, DOE Luzon Field Office in Pangasinan, and Mariano Marcos State University in 
Ilocos Norte.

This proposed bill seeks to reinforce the IAEECC resolution by promoting 
solar energy adoption in all government offices, in collaboration with the Department 
 Composed of the DOE Secretary as Chair, with Department Secretaries as Members: DBM, DOF, DILG, DPWH, DOTr,

of Public Works and Highways (DPWH) and the DOE.  It supports the national goal 
3
of achieving a 35 percent renewable energy share by 2030 and 50 percent by 2040.

The Philippines, being a tropical country with abundant sunlight, has 
significant solar potential. According to the National Renewable Energy Laboratory, 
the average solar radiation of the country ranges from 128-203 watts per square 
meter, or an average of 16.7 watts per square meter, translating to an average solar 
energy potential of 4.5-5.5 kWh per square meter per day.  In fact, many 
5
establishments, from residences to commercial buildings, and even schools, have 
already transitioned to solar power.  
Solar panels offer substantial long-term benefits, including significant financial 
savings. While traditional electricity costs tend to rise over time, utilizing a solar 
panel system allows establishments to secure energy costs at a consistent rate. 
Additionally, embracing solar energy, with government leading the way, reduces 
dependence on fossil fuels, a critical step as the Philippines commits to a 75 percent 
reduction in greenhouse gas emissions by 2030.

Given these advantages and the nation’s environmental commitments, we 
urge the swift passage of this bill.

National Government Offices Act”.   
SEC 2. Declaration of Policy. – It is hereby declared the policy of the State: 
(a) To mandate the development and utilization of renewable energy
resources in government buildings and offices;
(b) To establish the infrastructure and mechanisms to ensure efficient, cost-
effective and sustainable supply of power from solar energy systems; and,
(c) To ensure energy sufficiency of government agencies for the prompt and
unhampered delivery of services of its constituents.
SEC 3. Coverage. – This Act shall provide a framework for the establishment 
of solar energy systems in all national government buildings and offices. 
SEC 4. Establishment of Solar Energy Systems in National Government
