Building Energy Efficiency Policies and Practices in Pakistan: A Literature Review
Introduction
Energy Efficiency Policies in Pakistan represent a critical intersection of urban planning, environmental sustainability, and economic stability. As the household sector has emerged as the largest consumer of electricity—accounting for more than 51% of national consumption—the urgency to reform building standards has never been greater.
The Current State of Energy Consumption in Pakistan
To understand the necessity of robust energy efficiency policies, one must first grasp the scale of the energy crisis. Pakistan faces a persistent energy shortage characterized by supply deficits, distribution losses, and rising demand.
The country’s population is growing at an annual rate of 2%, with the urban population expanding even faster at 3% per annum—the highest rate in South Asia. By 2025, it was estimated that nearly half of the country’s population would reside in urban areas, placing immense pressure on residential infrastructure.
The residential sector’s dominance in energy usage is staggering. Between July 2017 and February 2018, households consumed 51% of the total national electricity. Despite this, the institutional setup for managing this consumption remains inadequate. While awareness regarding climatic design exists, a critical evaluation of the building stock reveals that most current structures are not designed with local climate conditions in mind.
The prevalent use of concrete and single-glazed glass fails to provide necessary thermal comfort, leading to a heavy reliance on active cooling and heating systems. This dependency exacerbates the energy crisis, making the revision and enforcement of energy efficiency policies a national priority.
Evolution of Building Codes and Regulatory Frameworks
The foundation of Pakistan’s regulatory approach lies in its building codes, which have evolved slowly over the past few decades. The initial Building Energy Code of Pakistan (BECP) was developed in 1990 by the National Energy Conservation Centre (ENERCON). This code provided minimum performance standards for building envelopes, lighting, and HVAC systems, largely adopting ASHRAE Standard 90.1. However, compliance was not mandatory, and the code lacked provisions for multifamily buildings, focusing primarily on commercial structures.
Recognizing the technological advancements and lifestyle changes since 1990, the government introduced the Building Code of Pakistan (Energy Provisions-2011). These provisions were promulgated into the main Building Code in 2013.
The EP-2011 is mainly adopted from ASHRAE Standard 90.1-2004 but includes Section 4, “Building Envelope,” which was tailored to local environmental conditions. The scope of these energy efficiency policies applies to new buildings with a connected load of 100kW or higher, or a conditioned area of 900 square meters or greater.
Despite these updates, significant gaps remain. The existing codes do not fully address the specific needs of single-family homes or low-rise multifamily units, which constitute the majority of the housing stock.
Furthermore, the lack of mandatory compliance mechanisms has rendered many of these energy efficiency policies ineffective in practice. The Pakistan Engineering Council (PEC) is responsible for updating these codes every three to five years, but the pace of adaptation often lags behind the rapid urbanization and technological shifts in the residential sector.
Institutional Framework and Implementation Challenges
A robust institutional framework is essential for the success of any policy. In Pakistan, the primary federal authority responsible for energy conservation is the National Energy Efficiency and Conservation Authority (NEECA).
Established in 2016, NEECA replaced ENERCON and is tasked with drafting guidelines, organizing training, and monitoring conservation programs. However, the performance of NEECA has been described as unsatisfactory in bringing about considerable change or enforcing strict compliance.
At the provincial level, the institutional setup is even weaker. Only Punjab province has established a dedicated body, the Punjab Energy Efficiency and Conservation Agency (PEECA), formed in 2016. PEECA works alongside NEECA to promote renewable energy and demand-side management.
In other provinces and administrative units like Islamabad and Gilgit-Baltistan, there is a distinct lack of organizational infrastructure to support energy efficiency policies.
Local authorities and municipal corporations, designated as the Authority Having Jurisdiction (AHJ) under the building code, are responsible for plan approval and enforcement. Unfortunately, these local bodies often lack the technical staff and expertise required to verify compliance with energy provisions.
Political instability and frequent changes in local government systems have further weakened their capacity. Consequently, even when energy efficiency policies are well-designed at the federal level, they fail to translate into action at the municipal level due to administrative inefficiencies and a lack of skilled personnel.
Key Issues: Housing Shortage and Thermal Comfort
The discourse on energy efficiency policies cannot be separated from the broader issue of housing shortage. Pakistan faces an estimated deficit of 10 million housing units, with 40% of this shortage located in urban areas.
The annual production of housing units (approximately 0.37 million) falls significantly short of the annual demand (0.6 million). This scarcity drives up costs and forces many residents into poorly constructed, informal settlements that ignore basic energy standards.
Thermal comfort is another critical concern. Studies indicate that a vast number of residential buildings in Pakistan do not provide adequate comfort temperatures. The BECP specifies indoor design temperatures of 21°C in summer and 26°C in winter, while the EP-2011 sets limits of not less than 25°C in summer and not more than 22°C in winter for HVAC-equipped buildings.
However, achieving these targets is challenging due to poor building envelope performance. Residents often resort to using active cooling systems, which increases household expenses and strains the national grid.
The lack of focus on passive design techniques—such as proper orientation, insulation, and natural ventilation—means that many new buildings are inherently inefficient. Without integrating thermal comfort considerations into energy efficiency policies, the cycle of high energy consumption and discomfort will continue. The housing paradigm must shift from merely providing shelter to ensuring energy-efficient, comfortable living environments.
Potential for Energy Conservation and Renewable Integration
Despite the challenges, there is significant potential for improvement through targeted energy efficiency policies. ENERCON has identified the building envelope as the area with the highest conservation potential, accounting for 40% of possible savings.
Other areas include overall lighting (29% potential) and high-efficiency appliances. For instance, replacing incandescent bulbs with Compact Fluorescent Lamps (CFLs) and promoting energy-labeled fans have shown promise.
The fan manufacturing sector, particularly in Punjab, has begun producing energy-saving fans that consume 40% less energy, demonstrating how industry-led initiatives can complement government energy efficiency policies.
Renewable energy integration remains low, with only 2% of total energy produced from renewable sources during the 2017-18 period. However, recent developments in wind and solar power projects offer hope.
The Alternative Energy Development Board (AEDB) and private sector entities have initiated solar PV projects in rural areas, reducing dependency on the national grid. Incorporating renewable energy mandates into energy efficiency policies could accelerate this transition, especially given Pakistan’s high solar potential.
Recommendations for Strengthening Policy Frameworks
To enhance the effectiveness of energy efficiency policies, several strategic steps are necessary. First, the building codes must be revised to specifically address residential buildings, including single-family and low-rise multifamily structures.
Second, compliance mechanisms must be strengthened by empowering local authorities with technical training and resources. Third, there is a need for greater public awareness and education regarding the benefits of energy-efficient design and construction.
Stakeholder engagement is crucial. Policymakers must involve architects, engineers, developers, and consumers in the formulation of energy efficiency policies to ensure they are practical and widely accepted. Additionally, financial incentives, such as low-interest mortgages for green buildings, could encourage adoption.
The "Naya Pakistan Housing Program," announced in 2018, presents an opportunity to integrate these energy efficiency policies into large-scale housing projects, although detailed implementation strategies remain unclear.
Conclusion
In conclusion, the literature review highlights that while Pakistan has established foundational energy efficiency policies, their impact is limited by weak institutional frameworks, a lack of enforcement, and a focus on commercial rather than residential sectors. The household sector’s dominant share of electricity consumption underscores the urgent need for targeted interventions.
By addressing housing shortages, improving thermal comfort through passive design, and leveraging renewable energy potential, Pakistan can transform its building sector. Future success depends on the rigorous implementation of updated energy efficiency policies, supported by skilled local authorities and informed citizens.
As the nation continues to urbanize, the value of these energy efficiency policies will only grow, offering a pathway to sustainable development and energy security.
