Abstract: The purpose of this study is to prepare a methodology for Designing and Modeling of a Nearly Net-Zero Energy building (office) in the composite climate of Delhi. Composite climates are cooling dominated and require constant cooling for at least 9 months in a year and dehumidification for at least 4 months in a year to achieve a comfortable indoor environment, but lead to higher cooling energy costs. Project included development of Baseline model, for this some of the data was taken from TERI IHC office and some of the assumptions were made on the basis of ASHRAE Std. 90.1. Various energy efficiency measures (according to ECBC guidelines) have been taken to reduce the energy consumption of the building by utilizing VisualDOE 4.1.2 energy modeling software. The final package of energy efficiency measures achieves 27% in energy savings of an established energy model baseline. Comparison has been done between Solar Thermal Technology and Solar PV Technology in terms of electrical energy saving potential. Solar Photovoltaic system found much better than Solar Thermal System. A photovoltaic (PV) system met the entire cooling demand of the building. Calculation of payback period determines whether the additional first costs associated with the nearly net-zero office design will pay back in energy cost savings. The results proved that the combination of ECBC energy efficiency measures and Solar PV system used to achieve 52% energy savings were cost effective with the payback period of 6.8 years and extra cost of construction was 5% more than the cost of construction for conventional building.Key words: Designing & Modeling of Nearly Net Zero Energy Building, Energy Modeling, ECBC,
