Dear Sir:-

we have Project in China it is a NC project

We don't get Electricity from Government we use natural Gas Generator for Electricity Production. then we use Diesel Generator For Backup

As per Leed Guideline in Credit EA PR 2 we claim saving Via CHP
(Combined Heat & Power)

The energy savings estimation compliance with LEED standards and the methodology are detailed in this chapter. As per cite given in the LEED reference guide for Green Building Design and Construction, Edition 2009.

“In accordance with the performance rating method, the parameters of the calculation of the CHP benefits are as follows:

The baseline buildings heating and cooling plant utilizes the backup energy sources of the design, or electricity if no backup source is present or specified.

When all electricity and thermal outputs of the CHP are used within design building, the electricity produced is considered free, as is the produced thermal energy. The input fuel for the CHP and any additional purchased energy is charged to the design building”

In this project the electricity required for building and factory operations is generated through Gas Generators. The following benefits can be acquired when using gaseous fuel for instead of liquid fuel:
Supreme combustion efficiency
No soot formation
Low ignition temperature
No smoke
This is evident that use of gaseous fuel is energy efficient as well as cost effective way of electricity generation. There are two scenarios are made based on type of fuel used viz. base case and proposed case. The electricity generation through diesel fuel is formulated as base case as per the LEED reference guide and the electricity generation through Compressed Natural Gas is the design case. The explanation on unit cost establishment and energy simulation assumption are given in the succeeding sections.

Note:

The relationships between – Building operation is almost same throughout the year – load, demand and utility rate are insignificant. Therefore, the exceptional calculations were done on net annual basis.

I need to Know Whether our Assumptions and Calculations are Correct
