摘要:
A static heat transfer model is derived from a system of dynamic equations by integrating the dynamic equations over different time periods. That static heat transfer model links periodic (e.g., monthly) energy usage with cooling and heating degree hours, humidifying and dehumidifying hours. Its coefficients of measuring correlations correspond to the thermal parameters of buildings. Temporal data from a building may be used to estimate the overall heat transfer parameters. A clustering scheme may be developed to decompose all the buildings into different clusters based on one or more similarity criteria. The overall heat transfer parameters are separated into values for the wall, roof and window using multiple buildings' data in the same cluster or group.

Estimating monthly heating oil consumption of a building that uses heating oil and non-oil source of energy, may include separating by applying statistical models, yearly consumption of oil data associated with the building into base load oil consumption and space heating oil consumption. The separating may also include determining monthly base load oil consumption associated with the building. Monthly space heating consumption of oil may be estimated by applying a heating degree day density function to the space heating oil consumption. The monthly space heating consumption may be aggregated with the monthly base load oil consumption to estimate the monthly heating oil consumption.
摘要:
Scheduling of building activities may be generated based on an objective function developed to optimize energy cost associated with performing activities in a building, which activities consume energy. The objective function may be solved based on the received plurality of activities, the energy sources consumed by the activities, the prices of energy, and subject to the one or more constraints.

Generating an optimal planning of building retrofit for a portfolio of buildings may include providing a plurality of objective functions that may be selected for maximizing cost reduction, maximizing green house gas emission reduction, or maximizing energy reduction, or combinations thereof. The objective function may be solved based on information including at least a retrofit cost for retrofitting a building, payback period specifying the length of time needed to recover the retrofit cost, a budget available for retrofitting the building, expected price of energy, estimated energy savings from retrofitting and estimated green house gas emission from retrofitting. The planning of building retrofit may be generated based on the solutions of one or more of the objective functions, which may provide for an optimal plan of building retrofit.

摘要:
The present invention provides a method and system making it possible to reduce a description of the impact of a disaster on the world at large to measurable, firm-specific operational and financial implications. This makes it possible to bridge the divide between disaster prediction and business planning by facilitating the translation of physical and other effects of a disaster on a business into a dollars-and-cents impact. The present invention also allows a user to evaluate the costs and benefits of various disaster mitigation plans and/or policies and to understand the combined effects of multiple mitigation plans.
摘要:
The present invention provides a method and system estimating the likelihood of employees not being available for work as a result of pandemic occurrence and effectiveness of related mitigation actions. The invention allows users to assess the impact of pandemic on availability of corporate workforce and to estimate the effectiveness of various corporate mitigation actions in terms of how such actions may reduce the adverse effects of a pandemic on employee availability by incorporating information on infection rate, perception, needs for family care and infrastructure availability into a system of algebraic and differential equations.
摘要:
A method and system estimating the gross output change in one or more industrial sectors is provided. Users are enabled to assess the impact of a pandemic on the demand market of a firm and to take proactive actions, for instance, shifting demand among industrial sectors, or among geographic regions. Economic impact is measured by gross output change in each industrial sector, as affected by workforce availability, infrastructure availability in each sector, and consumption change in each sector during the pandemic occurrence.
摘要:
A method of managing policy information in a mobile terminal by requesting an external policy management server for information about whether a change has been made to policy information and updating the policy information in a smart card web server of the mobile terminal to control access to resources based on the updated policy information.
