PREFACE

 

 

The Energy Crisis of the early 1970s resulted in a dramatic change in the planning and operation of construction activities in the developed countries, the emphasis being on optimal utilization of energy. In Pakistan, the last few years have witnessed the growing menace of energy shortage or "load‑shedding". Although it could be contributed to a slower rate of increase in our generation capacity, there are numerous other factors, which have been widening the gap between demand and supply in all sectors of our economy, especially the building sector.

 

According to a conservative estimate, buildings in Pakistan consume more than 40% of the total electricity produced. The demand of this sector is growing at the rate of almost 14% per annum, the highest among all other sectors. Rapid urbanization and resultant construction of buildings and rising standards of living are considered to be the causes of increased demand in this sector.

 

However, a critical evaluation would reveal that most of tie current buildings are not designed keeping in view local climatic conditions. Excessive use of concrete and glass, high levels of illumination and heavy reliance on space conditioning equipment are a common feature of our buildings. These buildings need extra energy to be made comfortable for their occupants.

 

Although a Building Code of Pakistan exists, it does not address this issue. Therefore, the National Energy Conservation Centre (ENERCON), Planning and Development Division was requested by the Environment and Urban Affairs Division, to come up with a Building Energy Code, as an addendum to the Building Code of Pakistan. The draft Code prepared by ENERCON, was presented to a Review Committee, constituted by the Environment and Urban Affairs Division (composition given on pages iii ‑ iv). Due to the technical nature of the Code, a Technical Sub‑Committee was formed (composition given on pages v ‑ vi). which went through each and every clause. The Code was finally approved by the Review Committee on the recommendation of the Technical Sub‑Committee after incorporating necessary amendments in the light of the comments of the members of both the committees.

 

This Code gives minimum performance standards for building windows and openings, heating, ventilating and air-conditioning (HVAC) equipment and lighting. Though mostly based on American Society of Heating , Refrigerating and Air‑Conditioning Engineers (ASHRAE) standards, every effort

 

has been made to ensure its applicability in our buildings. In accordance with the Building Code of Pakistan, which divides Pakistan into five climatic zones, standards have been provided for each zone.

 

In order to ensure general understanding of the Code for a large‑scale compliance, ENERCON has also prepared a Compliance Handbook for use in conjunction with this Code. It explains most of the terms and other technical aspects with the help of illustrative examples.

 

The building Energy Code is non mandatory at this stage. Both ENERCON and the Environment and Urban Affairs Division shall help the building professionals through introductory workshops and seminars to understand the conceptual basis of the Code. This is expected to ensure that the designs of buildings comply with the Code and are energy efficient. Once the infrastructure has substantially developed, the Code may be promulgated on a mandatory basis.

 

The Code will be reviewed by the Environment and Urban Affairs Division in consultation with ENERCON periodically as and when needed but not later than five years. Any valuable comments for its improvement will be highly appreciated.

 

We are grateful to ENERCON and the members of the two committees who made their valuable contribution to make this noble task a successful one.
