A Modular Building Controls Virtual Test Bed for the Integrations of Heterogeneous Systems

Description: This paper describes the Building Controls Virtual Test Bed (BCVTB) that is currently under development at Lawrence Berkeley National Laboratory. An earlier prototype linked EnergyPlus with controls hardware through embedded SPARK models and demonstrated its value in more cost-effective envelope design and improved controls sequences for the San Francisco Federal Building. The BCVTB presented here is a more modular design based on a middleware that we built using Ptolemy II, a modular software environment for design and analysis of heterogeneous systems. Ptolemy II provides a graphical model building environment, synchronizes the exchanged data and visualizes the system evolution during run-time. Our additions to Ptolemy II allow users to couple to Ptolemy II a prototype version of EnergyPlus,MATLAB/Simulink or other simulation programs for data exchange during run-time. In future work we will also implement a BACnet interface that allows coupling BACnet compliant building automation systems to Ptolemy II. We will present the architecture of the BCVTB and explain how users can add their own simulation programs to the BCVTB. We will then present an example application in which the building envelope and the HVAC system was simulated in EnergyPlus, the supervisory control logic was simulated in MATLAB/Simulink and Ptolemy II was used to exchange data during run-time and to provide realtime visualization as the simulation progresses.

Indoor Air Quality Assessment of the San Francisco Federal Building

Description: An assessment of the indoor air quality (IAQ) of the San Francisco Federal Building (SFFB) was conducted on May 12 and 14, 2009 at the request of the General Services Administration (GSA). The purpose of the assessment was for a general screening of IAQ parameters typically indicative of well functioning building systems. One naturally ventilated space and one mechanically ventilated space were studied. In both zones, the levels of indoor air contaminants, including CO2, CO, particulate matter, volatile organic compounds, and aldehydes, were low, relative to reference exposure levels and air quality standards for comparable office buildings. We found slightly elevated levels of volatile organic compounds (VOCs) including two compounds often found in"green" cleaning products. In addition, we found two industrial solvents at levels higher than typically seen in office buildings, but the levels were not sufficient to be of a health concern. The ventilation rates in the two study spaces were high by any standard. Ventilation rates in the building should be further investigated and adjusted to be in line with the building design. Based on our measurements, we conclude that the IAQ is satisfactory in the zone we tested, but IAQ may need to be re-checked after the ventilation rates have been lowered.

Achieving Energy Savings with Highly-Controlled Lighting in an Open-Plan Office

Description: An installation in a Federal building tested the effectiveness of a highly-controlled, workstation-specific lighting retrofit. The study took place in an open-office area with 86 cubicles and low levels of daylight. Each cubicle was illuminated by a direct/indirectpendant luminaire with three 32 watt lamps, two dimmable DALI ballasts, and an occupancy sensor. A centralized control system programmed all three lamps to turn on and off according to occupancy on a workstation-by-workstation basis. Field measurements taken over the course of several monthsdemonstrated 40% lighting energy savings compared to a baseline without advanced controls that conforms to GSA's current retrofit standard. A photometric analysis found that the installation provided higher desktop light levels than the baseline, while an occupant survey found that occupants in general preferred the lighting system to thebaseline.Simple payback is fairly high; projects that can achieve lower installation costs and/or higher energy savings and those in which greenhouse gas reduction and occupant satisfaction are significant priorities provide the ideal setting for workstation-specific lighting retrofits.

Identifying new technologies that save energy and reduce costs to the Federal sector: The New Technology Program

Description: In 1990 the New Technology Demonstration Program (formerly the Test Bed Demonstration Program) was initiated by the US Department of Energy`s Office (DOE`s) of Federal Energy Management Programs with the purpose of accelerating the introduction of new technologies into the Federal sector. The program has since expanded into a multi-laboratory collaborative effort that evaluates new technologies and shares the results with the Federal design and procurement communities. These evaluations are performed on a collaborative basis which typically includes technology manufacturers, Federal facilities, utilities, trade associations, research institutes, and other in partnership with DOE. The end result is a range of effective technology transfer tools that provide operations and performance data on new technologies to Federal designers, building managers, and procurement officials. These tools assist in accelerating a technology`s Federal application and realizing reductions in energy consumption and costs.

A whole building demonstration of re-cover over an existing wet roof

Description: Roof re-cover, the practice of installing a new roof over an existing failed roof, has become commonplace. The 1994 National Roofing Contractors Annual Roofing Survey reported that approximately 33% of current reroofing activity is re-cover. Market trends suggest that re-cover will become an increasingly more popular option. Moisture in the failed roof complicates the decision whether or not to re-cover and how to do the recover if that is the decision. If the root to be re-covered contains moisture that will not be removed during reroofing, this moisture must be able to escape from the roof system. Otherwise, moisture entrapped in the roofing system may eventually lead to the mechanical failure of fasteners and the roof deck, especially if it is metal. In 1991, the Oak Ridge National Laboratory (ORNL) surveyed its own roofing inventory and found that 164 buildings or 70% of the laboratory roof area needed reroofing. Because of the high cost of tear off and replacement, an alterative was sought. This paper describes the procedure employed to determine the suitability of a particular roof system on a laboratory building for re-covering. The procedure involves the use of field diagnostics, laboratory experiments and numerical simulations that demonstrate that the particular roof type can be re-covered. Furthermore, the building and roof system have been monitored for approximately 16 months after re-cover. The monitoring results are compared to the numerical simulations and demonstrate that the roof system is drying and that the reroofing strategy that they used is cost-effective.

Self drying roofs: What! No dripping!

Description: Many roofs are replaced because water accumulates in portions of the roofing system.These accumulations can cause dripping, accelerated membrane failure, poor thermal performance, the threat of structural decay, and the depreciation of building assets. Traditionally, the roofing industry has been concerned with controlling the inflow of water into the roof. An example of this strategy would be the development of a more reliable membrane. However, roof membranes inevitably leak. For this reason, the roof design strategy of the future must be concerned with controlling water outflow. The requirements of this type of roof system are described. Under normal operating conditions (no leaks), the total moisture content of a self-drying roof system shall not increase with time and condensation shall not occur under the membrane during winter uptake. Moisture vapor movement by convection must be eliminated and the flow of water by gravity through imperfections in the roof system must be controlled. After a leak has occurred, no condensation on the upper surface of the deck shall be tolerated and the water introduced by the leak must be dissipated to the building interior in a minimum amount of time. Finite difference computer modeling is used to demonstrate the effectiveness of the design. The impact of deck and insulation permeance, climate, leaks, and wintertime water uptake are simulated. A database of simulations is qualitatively described; this database will be used in future work to produce a simplified means of assessing the design parameters of a self-drying roof system.

What`s new in federal energy management: FEMP program overview. Federal energy saver showcases

Description: To promote widespread Federal energy efficiency, agencies are showcasing their best energy efficiency, water conserving, and solar and other renewable energy technologies. To highlight these successful energy-efficient projects, Executive Order 12902 directs agencies to designate at least one newly constructed or existing building as a showcase facility. At existing facilities, agencies must also try to incorporate cogeneration and indoor air quality improvements. Agencies are directed to develop and implement effective plans to make these showcase projects happen. Project successes will show the strength of partnering with other agencies, energy services companies, utilities, and national laboratories, and of using the US Department of Energy Federal Energy Management Program (FEMP) as a resource. The goal is Federal facilities operating at peak efficiency. A Federal Energy Saver Showcase plaque is prominently displayed at each showcase site, notifying visitors they are entering a government building that successfully conserves energy and water and saves taxpayer dollars.

What`s new in federal energy management: FEMP program overview. SAVEnergy program

Description: The SAVEnergy Program provides direct assistance to Federal agencies in identifying and implementing energy efficiency and water conservation measures. The Energy Policy Act of 1992 (EPAct) and Executive Order 12902 require that Federal agencies reduce the energy consumed in Federal buildings. The Executive Order increases the goal to a 30% reduction, compared with 1985, by 2005. In addition, agencies are required, to the maximum extent possible, to install all energy and water conservation measures with paybacks of less than 10 years. To help meet these goals, the US Department of Energy`s (DOE`s) Federal Energy management Program (FEMP) recently initiated the SAVEnergy Program. The SAVEnergy approach has three key elements: The Action Plan with recommended conservation actions and complete proposals on how the agency can implement them; The Action Team to implement the SAVEnergy Action Plan; The FEMPTracks database to evaluate the SAVEnergy Program (and all other FEMP programs) and record progress toward conservation goals.

What`s new in federal energy management: FEMP program overview. Federal Energy Management Program

Description: The US government has an enormous cost-saving opportunity as the largest energy user in the world. In 1994, the government spent $8 billion for its 500,000 buildings, it vehicles, and process energy. The US Department of Energy (DOE), Federal Energy Management Program (FEMP) reduces the cost of government and makes it work better through energy efficiency, use of renewable energy, and water conservation. FEMP leads Federal energy efficiency efforts and helps Federal energy managers identify and procure the best, most cost-effective energy-saving projects. It does this through proactive problem solving; an aggressive emphasis on increasing the number and quality of projects; and effective partnerships among agencies, utilities, the private sector, and states. Partnerships lead to increased motivation and education and reduced barriers to successful procurement. As the lead organization implementing legislation and Presidential direction for Federal energy efficiency, FEMP administers an interagency energy committee and task force and collaborates with the DOE national energy laboratories. FEMP works with energy service companies, energy savings product manufacturers, and utilities. This partnership will lead to a $1 billion investment by companies willing to invest in return for a share of the energy cost savings. With FEMP project financing, audits, training and technical assistance, and new technology demonstrations, agencies overcome obstacles to achieving widespread energy efficiency.
