3. Introduction Buildings account for nearly 40% of global energy consumption, with HVAC and lighting consuming approximately 40% and 15% of this energy, respectively. These statistics highlight the significance of exploring various strategies for HVAC energy saving. To address this issue, numerous research studies have examined different approaches and technologies aimed at improving energy efficiency in buildings. Diverse range of strategies and technologies available for achieving HVAC energy savings in buildings. By integrating and synthesizing the research findings, this the current state of knowledge in this field while also identifying potential future research directions to address existing knowledge gaps by using Climatology- degree days and degree hours .

4. Objective What you are going to do this work? As I’m an HVAC engineer we have installed 4500 TR chiller and 4374 TRH of TES and 274 AHU installed with VFD will be studying the best and most efficient method of energy saving in HVAC system. Wanted to run the HVAC system based on Climatology- degree days and degree hours Why you have to do this work? In a building total energy consummation nearly 40 to 55% are consumed by HVAC if we reduce the energy consummation automatically we can reduce the carbon foot print   how you will do? By adopting various methods in energy saving will be able to achieve the set benchmarking for chillers and AHU : Centre of Research and Consultancy Ph.D Admission 2024 July

5. Reasearch GAP The higher-level functions of heat, ventilation and airconditioning (HVAC) systems changed along the last forty years, simply from providing thermal comfort to a multipart set of requirements. Since the eighties, HVAC systems must also be able to provide indoor air quality and to recover energy. During the mentioned period, the manufacturing project teams somewhat redesigned those systems in order to accommodate based on Climatology- degree days and degree hours . This procedure disagrees with the fifth theorem of Axiomatic Design (AD), which in such cases requires a complete system redesign. The recent rise in the price of the oil barrel emphasizes the need to recover energy in any building, namely in HVAC systems. The energy regulations, ASHRAE 90.1 in the US and the EPBD (Energy Performance Building Directive) in the EU, address this problem. The aim of this paper is to analyse an HVAC system that is independent in terms of thermal comfort and indoor air quality, and to add the “reduce energy” functional requirement (FR). This new FR has four “children” functions: “adapt flows”, “recover energy”, “choose equipment efficiency” and “define efficient network conditions”. Raising the design matrix to a set of well-known market solutions allows identifying the existing couplings. Taking into account the independent solutions alone, and merging them with the guide solutions established in the regulations, one can conclude that regulations might lead to efficient working conditions.

6. Existing Method Currently existing method to save energy saving is VFD Using thermostat to control temperature Upgrade Your HVAC System. Schedule Routine Maintenance. Adjust Your Thermostat Settings. Invest in a Smart Thermostat. Add or Update Insulation. Batten Down the Hatches. Replace Your Air Filters Centre of Research and Consultancy Ph.D Admission 2024 July

7. Proposed Method Climatology- degree days and degree hours Outdoor temp model Thermal Simulation ASHRAE transfer function model Simulation improvement by using DH correction Integration of result Application of the management approach Centre of Research and Consultancy Ph.D Admission 2024 July

8. By using the Climatology- degree days and degree hours we can reduce the energy consumption without any capital cost. Conclusion Centre of Research and Consultancy Ph.D Admission 2024 July
