“…The simple payback is the number of years the savings from the retrofit packages will take to return to the home owner the initial capital cost (Burgett et al , 2013). The cost analysis was carried out by calculating the simple payback period to compare each retrofit package and determine how long it would take to get back the money invested.…”

Purpose The purpose of this paper is to develop a set of affordable retrofit packages that can be applied to existing residential buildings in hot-humid regions to improve occupants’ thermal comfort and reduce energy consumption. Design/methodology/approach A critical review of relevant literature to identify passive design strategies for improving thermal comfort and reducing energy consumption in hot-humid climates with focus on the building envelope was conducted in addition to a simulation study of an existing building typology in study area. Findings There is enormous potential to reduce energy costs and improve thermal comfort through building retrofit packages which is a recent concept in developing countries, such as Nigeria. Analysing the results of the retrofit interventions using building energy simulation helped in developing affordable retrofit packages which had optimum effect in improving indoor comfort temperature to the neutral temperature specified for hot humid Nigeria and further down to 3°C less than that of the reference building used. The use of passive design strategies to retrofit the building might help homeowners reduce their annual energy consumption by up to 46.3 per cent just by improving the indoor thermal comfort. Originality/value In addition to improving thermal comfort and reducing energy consumption, this research identified affordable retrofit packages and considered its cost implications especially to low-income earners who form a larger population of Lagos, Nigeria, as this was not considered by many previous researchers.

“…Previous research has measured how effective a retrofit intervention can be on saving energy (Burgett et al , 2013). On the other hand, few studies are available which show the use of simulation modelling to develop retrofit packages to improve the thermal performance of buildings.…”

“…This work seeks to assess the ability of EnergyPlus (via BEopt) to simulate residential energy use in a hot and humid climate by use of 1) a database of residential home energy audits, 2) data from a smart grid demonstration project, and 3) modeling. Understanding how these models predict actual energy usage in Austin's hot and humid climate under different design considerations can lead to better simulations and retrofit recommendations [43,44].…”

“…The results indicated that the implemented strategy contributed to the reduction of the overheating problem of the building and maintained comfortable indoor conditions adding to the improvement of occupant well-being. Burgett et al [13] demonstrated the application of energy simulation as an effective tool for specifying cost-effective residential packages that will reduce energy consumption by 30%. The authors used single-family buildings in the hot-humid climate in the southern USA to demonstrate the application.…”

Targeting existing residential buildings for retrofit improvement presents significant prospects for global reduction of energy-usage and carbon footprints. Energy consumption of the existing single-family building in the hot-humid climate zone needs to be targeted for improvement due to their potential energy-savings and sizeable market share. This paper proposes and evaluates energy savings and cost-effectiveness of a whole building retrofit package for single-family residential buildings built between 1950 and 1970. The study outlined a survey conducted using the clustering data mining technique on Florida Single-Family Residential (SFR) homes to determine the essence of the building envelope, patterns of construction, and Heating, Ventilation, and Air-Conditioning (HVAC) systems. The evaluation of the energy efficiency measures (EEMs) effectiveness is performed utilizing Autodesk Revit and a Six-Step modeled framework. This framework consists of baseline model development, validation of the model with an actual case study building, identification of potential EMMs, evaluation of EEMs individually and incorporating the selected EMMs into retrofit package and maximizing the energy-saving and cost-effectiveness of the proposed retrofit package. The study develops proposed retrofit improvement package detailing replacement & improvement EEMs, implementation cost, annual energy savings (kWh), cost-saving ($), and payback period (years) for each individual EEM as well as the combined/total energy improvement package. The paper further explored the usage of solar photovoltaics (PV) energy generation options to offset the remaining energy-use after the implementation of the proposed retrofit package.
