由于能源需求与能源生产之间的差距日益扩大，巴基斯坦等发展中国家正在经历严重的能源危机。由于建筑物是巴基斯坦能源的主要消耗者，因此必须立即采取措施，通过制定建筑物节能措施来减少能源消耗。该国大多数建筑物使用分布式供暖/制冷设备，即空调 (A/C) 来调节建筑物温度。这些空调消耗建筑物中的大部分能源，并且经常遇到诸如加热或冷却未占用空间以及建筑物中某些区域过热/过冷等问题。这些问题主要是由于空调的独立手动控制而产生的，可以通过安装集中供暖、通风和空调 (HVAC) 系统来解决。然而，在这些建筑物中部署实际的 HVAC 系统的成本仍然很高。成本与对居住者的干扰以及安装暖通空调基础设施的美元成本有关。此外，与拆除或更换现有空调装置相关的成本也很高。因此，在这项工作中，我们通过利用建筑物中现有的分布式供暖/制冷基础设施来抽象 HVAC 系统的功能，以提供低成本的集中指挥和控制机制，即改造低成本供暖通风和空调（RetroHVAC）系统。我们设计了一个占用检测系统，并将其纳入RetroHVAC 系统中，以增强其节能潜力。此外，桌面应用程序旨在支持用户交互和策略执行。基于时间调度、温度阈值监测和实时占用信息的不同RetroHVAC控制策略的实验评估表明，RetroHVAC系统可以在不影响用户舒适度的情况下大幅降低建筑能耗。
Developing countries such as Pakistan are experiencing severe energy crises because of an increasing difference between energy demand and energy production. Since buildings are the major consumers of energy in Pakistan, immediate steps must be taken to reduce energy consumption by devising energy efficient measures for buildings. The majority of buildings in the country use distributed heating/cooling devices, i.e., air conditioners (A/Cs), to regulate building temperature. These A/Cs consume most of the energy in the buildings and are often subjected to problems such as heating or cooling unoccupied spaces and overheating/overcooling some areas in the building. These problems arise mainly because of independent manual controls of A/Cs and can be addressed by installing centralized heating, ventilation, and air-conditioning (HVAC) systems. However, the cost of deploying an actual HVAC system in these buildings remains high. Costs are associated with disruption to occupants as well as the dollar cost of installing the HVAC infrastructure. Moreover, the cost associated with removal or replacement of the existing A/C units is also substantial. Therefore, in this work, we abstract the functionality of the HVAC system by using the existing distributed heating/cooling infrastructure in buildings to provide a low-cost centralized command and control mechanism namely Retrofitting low-cost Heating Ventilation and Air-Conditioning (RetroHVAC) system. We designed an occupancy detection system and incorporated it into the RetroHVAC system to enhance its energy-saving potential. Additionally, a desktop application was designed to enable user interaction and policy enforcement. Experimental evaluation comparing different RetroHVAC control strategies based on time scheduling, temperature threshold monitoring, and real-time occupancy information show that the RetroHVAC system can substantially reduce the building energy consumption without compromising user comfort.
