Application of Building Information Modeling for Reducing Energy Consumption by Building Envelope Improvement, Case study: Residential buildings

Abstract

This paper aimed to study the application of building information modeling to reduce the energy consumption of buildings in air conditioning systems by analyzing suitable building envelope improvement approaches. The case study is a residential building from the government's standard design. Using the Autodesk Revit program, research the appropriate scenario to improve building envelope materials for reducing energy consumption and cost-effective investment by considering the reduced cooling load in the air conditioning system and additional investment in each alternative approach. The results found that four alternatives could reduce electricity consumption by more than 40 % and invest less than 100,000 baht. Changing the glass type to reflective glass and installing 3 inches of fiberglass insulation in the west wall and installing 6 inches of fiberglass insulation on all top floor ceiling areas is the best building envelope improvement scenario, able to reduce annual energy consumption by 44% with an approximate investment cost 47,000 baht and 0.78 years payback period
