Cooling Degree Day Analysis As A Climate Impact Indicator For Different Locations Of Poland And India
Abstract
Energy analysis plays an important role in developing an optimum and cost effective design of HVAC system for
a building. Although there are different energy analysis methods, which vary in complexity, the degree-day methods are the
simplest methods and well-established tools. Energy consumption increases as the number of heating and cooling degree
days increases and falls as the number of heating and cooling degree days falls. The value of degree-days is a measure used
to indicate the demand for energy to heat or cool buildings. The monthly or annual cooling and heating requirements of
specific buildings in different locations can be estimated by means of the degree-days concept. The base temperature is the
outdoor temperature below or above which heating or cooling is needed. Cooling degree-days enable better benchmarks to
be developed for air-conditioned buildings, allow improved Building Energy Management System operation and produce
better energy estimating methods. These three factors could make real contribution to energy efficiency and CO2 emission
targets. In this study the degree days for period 2008-2012 were calculated for Poland (5 cities) and India (5 cities) in each
country. Cooling Degree Days for India were calculated for base temperature from 18 oC till 26oC. The Cooling Degree
Days for Poland were calculated for base temperaturę from 18 till 28oC.The average annual value of CDD18 for Indian cities
is CDD18 for Chennai is 4108, for Kolkata CDD18=3360, for New Delhi CDD18=3015, for Mumbai CDD18=3469, for
Mangalore CDD18=3449. The average annual value of CDD18 for Polish cities is Suwałki CDD18=99 for Zielona Gora
CDD18=75, Zakopane CDD18=43, Gdansk CDD18=62, Warsaw CDD18=182.
