Calibrated detailed energy models are often used to identify economic deep retrofit opportunities in existing buildings. But the uncertainty in building performance makes it technically unrealistic to reach a single “best fit” model without extensive sub-metering and domain experts on the project which is typically labor intensive. To address this problem, researchers have been adopting stochastic...
With human environmental footprint exceeding the world's regeneration capacity by about 30%, conserving energy and reducing emissions and waste are critical for sustainable living. A new prototype of living is eco-communities which consist of a set of buildings and associated devices for energy generation, conversion, consumption, storage and recovery networks trying to be self-sufficient as much...
Electro-thermal domestic heating systems represent excellent potential sources for demand response and demand side flexibility given the large amount of storage inherent in them. However, they must be modeled using an approach which adequately captures the detailed physics of the problem (in order to properly assess the different sources of inherent storage), and yet is simple enough to be generalizable...
Due to climate change issues, fossil fuel depletion and increasing economic pressure, "smart" cities will have significantly altered physical, social and economic systems, built upon smart infrastructure. Key infrastructure is energy, with focus on electricity. The paradigm of physical, data transfer and information flow layers of the smart city power grid is shown. Challenges of the new...
Building energy consumption refers to various energy used in buildings, including energy consumption in heating, air-conditioning, illumination and hot water supply etc. Based on a comprehensive analysis of all kinds of main factors influencing building energy consumption, this paper simulates the future development tendency of building energy consumption in China through a quantitative analysis so...
This document reports the development of a hybrid and autonomous energy model with solar PV panels and a small CHP (combined heating and power production) system whose primary energy source is the biomass. Also it will be presented several rules for to achieve new energy efficiency levels of a service building. This energy model is also a new sustainable paradigm on energy consumption (electrical...
It is commonly believed that telework is good for the environment because it saves energy through reduced commuting. Millions are teleworking worldwide. Some peer-reviewed publications in the last decade have shown that the principles of life-cycle assessment (LCA) have to be applied to telework (just like to other products and services) in order to arrive at a comprehensive assessment of all the...
The purpose of this paper is to analyze the electricity residential energy consumption using system dynamic approach. Since the effects of state decisions and strategies regarding the consumption of electrical energy have gained importance in recent years, firstly, we have used the science of system dynamic in order to simulate the electricity residential energy consumption. Major variables and helping...
The transition to Building Information Modeling (BIM) represents a substantial shift from existing business practices in the architecture, engineering, construction, and facility operations (AECO) arena. While the move from drafting to computer aided design (CAD) sought to automate an existing business practice, successful BIM virtually builds a structure first. Similar to the virtual prototypes in...
This paper presents an approach to the modelling and simulation of highly distributed power systems, in the context of existing UK distribution networks. The model is part of a framework to assess the network impact of high-penetrations of micro-generation, as well as demand side management (DSM) measures. This framework supports the representation of the 11 kV and low voltage distribution network...
The experimental system of photovoltaic window generation was installed on the test chamber. The mathematic model of photovoltaic module, used in an integrated building simulation tool ESP-r, was verified with the measured solar power. On the basis of the model validation, Photovoltaic window generation systems, used on facades of an office building located in Beijing, Shanghai and Hong Kong, were...
The distributed energy resources customer adoption model is used to estimate the value an Oakland nursing home, a Riverside high school, and a Sunnyvale data center would need to put on higher electricity service reliability for them to adopt a consortium for electric reliability technology solutions microgrid (CM) based on economics alone. A fraction of each building's load is deemed critical based...
In this paper we examine the inevitable interconnection between engineering, economics and environmental impact in the electricity industry, and how they shape the roles engineers can and should play in designing the energy systems of the future. Involvement of engineers needs to happen in two ways: engineers can bring a technological awareness to the policy debate; and engineers need to be able to...
Effective power supplying service management is an important prerequisite for power supply enterprises to win in competitive market. In this paper, we analysis the characteristics of power supply enterprises, follow the thought of "Identifying problems - Finding problems - Solving problems", that is identifying problems based on the theory of Gaps model, establishing a service quality evaluating...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
