A Review: Buildings Energy Savings - Lighting Systems Performance

Energy savings and economics of retrofitting single-family buildings

This s tudy a s se s se s the energy savings and cost-effect iveness of individual retrofi t op t ions and packages of measu res in s ingle-family buildings, ba sed on analysis of me te red energy consumpt ion and actual installation costs. We present results for 14 individual shell, heating system, and water heating measures, as well as 21 electric utility weatherization programs. The data on ...

Draft Report: Energy Savings for Load- Shedding Ballast for Fluorescent Lighting Systems

Energy-Efficient Lighting Options: Predicted Savings and Occupant Impressions of Lighting Quality

Detailed simulations of lighting and HVAC energy consumption were performed on a prototype office building in six North American climates. The goal of these simulations was to calculate the overall energy savings attributable to reductions in lighting power density (LPD) from 25.8 W/m (past practice) to 17.2 W/m (current code) to 8.6 W/m (low). Results showed that as LPD decreases, reductions i...

The Energy Audit Activity Focused on the Lighting Systems in Historical Buildings

The energy audit for a building is a procedure designed mainly to obtain adequate knowledge of the energy consumption profile, identify, and quantify opportunities for energy savings by a cost-benefit analysis and report, clearly and comprehensively, about the obtained results. If the audit is referred to a building with a significant historical and artistic value, a compatibility evaluation of...

Energy Performance Visualization of Buildings

Electricity consumption of a building can be broken down into three different categories based on their end use. These categories are plug load, lighting load and mechanical load. This break down of electricity consumption is enabled by a Building Management System (BMS) which is powered by a collection of sensors in the building and a software. However, in the building management industry it i...
