Punjab ECBC shall be applicable to buildings with a connected load of 100 KW or more; or contract demand of 120 KVA (kilo volt ampere) or more; or all buildings with airconditioned floor area of 500 sq m (5,000 sq ft) more as this covers most of the big commercial complexes, institutional buildings, housing complexes in the state. A 3-BHK (bedroom-hall-kitchen) with airconditioners, approximately consumes around 10KW of electric power. So, a group housing society with even 10 apartments will have a connected load of more than 100KW. Most of such housing complexes will be covered by these norms.
The Government of India enacted the Energy Conservation Act in 2001 to promote energy conservation. It was amended in 2010. BEE was established under the Act to develop policies to reduce energy consumption and coordinate with stakeholders. “BEE helped develop the ECBC. Under the Act, states can amend ECBC to suit their conditions. The Punjab ECBC is formulated to meet local requirements.
In case of mixed use buildings, if the connected load of the commercial part qualifies for the applicability of this code then the commercial part of the building also has to comply with the code. In case the project is to be built in phases, the Punjab ECBC shall be applicable to the whole building load in total and not the individual buildings designed later in phases (as was done earlier). Additions or alterations made in existing buildings and places where airconditioned floor area exceeds threshold area have to be made Punjab ECBC-compliant. All additions, together with the existing building have to comply with the requirements of the code.
Already installed space conditioning systems (a centrally air-conditioning system which allows for controlling of air quality, temperature and humidity within a space for human comfort) do not need to comply with PECBC. However, any new equipment installed must comply with specific requirement applicable to that equipment under the code.
It will be mandatory to use equipment having minimum three star ratings. Even ceiling fans shall comply with the provisions of the clause. It has also been proposed to have automatic shut off (after 10 minutes) of lighting fixtures in commercial and office buildings while they are not in use. It also restricts the size of windows as excessive use of glass in this tropical climate increases energy consumption. Likewise, there will also be parameters to install huge signage and advertisements. It incorporates parameters that can maximise natural light and ventilation.
