An Evaluation of the Good Cents Program in College Station, Texas |
|

Description:
|
|
The Good Cents Program is designed to encourage builders to build more energy-efficient homes. One difficulty with evaluating this type of program is that energy use not related to outdoor air temperature introduces a large amount of unexplained variability into total energy use. This study uses a statistical method that separates energy related to outdoor temperature from energy not related to outdoor temperature. Three-parameter models have proven to be very useful in modeling residential energy use. This study uses parameter estimates of three-parameter models to compare a treatment group of Good Cents houses to a control group of non-Good Cents houses. Parameters used are cooling slope, heating slope, and Normalized Annual Consumption (NAC). |

Characterizing Green Residential Construction for Green Builder Programs and Construction Education |
|

Author:

Description:
|
|
The importance of green construction techniques and products is impacting the residential construction sector as educated clients are beginning to demand environmentally friendly homes and green builders are finding success constructing and selling green homes. In response, the popularity and number of residential green building programs is increasing around the country, as is an emphasis on green building at universities. However, there is still much debate concerning exactly what a green residence is. Existing green building programs have both different categories of green features and different specific measures that are used in their checklists to certify green homes. Many features could fit into several categories, thus making a consensus on exact placement difficult. This paper discusses the similarities and differences in green residential rating systems between eight green building programs throughout the United States. |

Description:

|
This paper reports the findings of a mail survey of the active members of the Building Officials Association of Texas. The objective of this study was to identify relevant issues affecting the adoption of the 2000 International Building Code (IBC) and measure the level of receptiveness of the 2000 IBC among Texas code officials. Descriptive statistics were used to report the findings of this study. A total of 233 survey questionnaires were mailed and 166 completed forms were returned for a 71.2% response rate. The survey results revealed that 74.1% of survey respondents planned to recommend adoption of the 2000 IBC for use in their community. Of the 123 code officials that intend to recommend adoption of the 2000 IBC, 54.9% stated that the factor that most affected their decision was It (the 2000 IBC) is designed to facilitate uniformity in building construction nationwide. |

Green Building: Current Status and Implications for Construction Education |
|
|
Author:

|
Stephen P. Mead |
|
Description:
|
|
Given increased global concerns with environmental degradation, declining natural species, and global warming, there has been an accelerated movement toward increasing the sustainability of the built environment. In the United States this movement is called the Green Building movement. Green Buildings are buildings that are designed, constructed, operated, and demolished in an environmentally and energy efficient manner. Green Building concepts include energy efficiency and conservation, indoor environmental quality, resource and material efficiency, and improved long term durability. This paper will describe the current state of Green Building in the United States through an investigation of Green Building design principles and four case studies of recently completed commercial buildings. Additionally, the paper will describe the LEED system for measuring building sustainability. |

Structurae is a
huge database that is a showcase for the works
and the art of structural engineering. The
database contains structures created by civil
and structural engineers, or those where their
input was crucial and necessary. It also
contains those structures that may be
interesting to engineers, but were created by
other professionals, e.g. architects |

User Requirements Modelling in Design of Collaborative Virtual Reality Design Systems |
|
|
Author:

Per Christiansson |
|
Description:
|
|
Advanced Information Technology today gives us the opportunity to implement sophisticated distributed systems for collaborative design. Persons with different interests and competencies in the building process such as architects, installation engineers, structural engineers, clients, and builders can all at least theoretically be brought together in a distributed design space where a virtual building is drafted, designed, built, and functionally evaluated. A design space built in a virtual reality environment will enable us to realistically and efficiently simulate the form, function, construction, and use of the building under consideration. The paper presents experiences from the early phases of user requirements formulations and design of such collaborative design spaces. The findings are mainly based on collaborative university and consultant engineering company work done in the EU ISTproject 'Distributed Virtual Workspace for enhancing Communication within the Construction Industry - DIVERCITY' as well as experiences from student collaboration in distributed learning environments and earlier research within the area. The early conceptual design of the virtual workspace follows the so called Contextual Design methodology which gives input to the subsequent data modelling work and implementation in an object oriented web distributed environment. The method used is described and examples on resulting Work Models (work flow, sequence and artefact models) are presented and commented on. |

Whole-Building Energy Simulation with a Three-Dimensional Ground-Coupled Heat Transfer Model: Preprint |
|
|
Author:

M. Deru,R. Judkoff,J. Neymark |
|
Description:
|
|
A three-dimensional, finite-element, heat-transfer computer program was developed to study ground-coupled heat transfer from buildings. It was used in conjunction with the SUNREL whole-building energy simulation program to analyze ground-coupled heat transfer from buildings, and the results were compared with the simple ground-coupled heat transfer models used in whole-building energy simulation programs. The detailed model provides another method of testing and refining the simple models and analyzing complex problems. This work is part of an effort to improve the analysis of the ground-coupled heat transfer in building energy simulation programs. The output from this detailed model and several others will form a set of reference results for use with the BESTEST diagnostic procedure. We anticipate that the results from the work will be incorporated into ANSI/ASHRAE 140-2001, Standard Method of Test for the Evaluation of Building Energy Analysis Computer Programs. |

Thermal Performance of Unvented Attics in Hot-Dry Climates |

Description:
|
|
As unvented attics become a more common design feature implemented by Building America partners in hot-dry climates of the United States, more attention has been focused on how this approach affects heating and cooling energy consumption. The National Renewable Energy Laboratory (NREL) has conducted field testing and hourly building simulations for several Building America projects to evaluate energy use in vented and unvented attics in hot-dry climates. In summer, testing of the Las Vegas protoype house demonstrated that the thermal performance of an unvented attic is highly dependent on duct leakage. |

Description:
|
|
This OIT BestPractices Case Study describes how the Equilon Enterprises oil refinery in Martinez, California undertook a plant-wide energy assessment that focussed on three key areas: waste minimization, process debottlenecking, and operations optimization. The assessment yielded recommendations, which, if implemented, can save more than 6,000,000 MMBtu per year and an estimated $52,000,000 per year, plus improve process control and reduce waste. |
