The International Institute for Sustainable Laboratories (I2SL) is pleased to acknowledge the winners of the 2015 Go Beyond Awards. Go Beyond Award winners demonstrate their commitment to excellence in sustainability in lab and other high-tech facility projects by going beyond the facility itself to consider shared resources, infrastructure, services and neighboring communities; and contribute to increased use of energy-efficient and environmentally sustainable designs, systems and products. The 2015 Go Beyond Awards were presented during a special luncheon ceremony at the 2015 I2SL Annual Conference on Monday, September 21, 2015, in San Diego, Calif. I2SL presented four 2015 Go Beyond Awards in two categories: Individual and Project. James Dykes, Sustainable Labs Canada James Dykes, a recently retired architect from Public Works and Government Services Canada (PWGSC), received an Individual Go Beyond Award for his many years of commitment to making sustainability a key factor in lab design. Dykes is the Founding President of, and driving force behind, Sustainable Labs Canada (SLCan), a non-profit organization that promotes sustainable design and operation practices in labs and other high-tech facilities. Dykes developed and strengthened relationships between SLCan and the Real Property Institute of Canada (RPIC), I2SL and other organizations in Europe with similar goals. As a member of the RPIC Board of Directors, Dykes acted as the lab business sector representative from PWGSC, ensuring content included lab-focused issues in the RPIC Real Property National Workshop Program. Over the course of his career, Dykes has served on numerous volunteer boards, delivered conference presentations on lab design, guest lectured at several universities and colleges and was an Assistant Adjunct Professor with the Univ. of Calgary for 12 years. He worked with the Labs21 program for most of its existence, and continues to participate in I2SL’s Global Sustainable Laboratory Network. Allison Paradise, My Green Lab The second Individual Award was presented to Allison Paradise, Executive Director of My Green Lab, a non-profit organization that promotes safe, sustainable practices and equipment in labs. Paradise has been a passionate champion and advocate for sustainable lab practices since before she began the My Green Lab program several years ago. Through My Green Lab, Paradise partners with organizations to implement energy reduction, water reduction, waste management and green chemistry programs; and connects lab personnel with sustainable procurement opportunities. Working with utility providers in California, Paradise prepared the “Market Assessment of Energy Efficiency Opportunities in Laboratories,” which involved a survey of equipment use and energy efficiency that was given to almost 1,200 scientists and lab operators across the U.S. The survey identified energy-efficiency opportunities in labs that Paradise is helping to drive forward through the creation of the Center for Energy Efficient Laboratories. Jackson Laboratory for Genomic Medicine, Farmington, Conn. One of this year’s Project Awards was presented to the Jackson Laboratory for Genomic Medicine, a global leader in considering the environmental impact of its facilities and operations. The Jackson Laboratory combines inviting collegial space with efficient labs, while using a variety of energy conservation measures to maximize building performance. The lab maximizes daylight while limiting peak solar loads, and utilizes high-efficiency equipment and an improved thermal envelope. To ensure indoor air quality, the lab also has a monitoring system and occupancy sensors with the ability to reduce outdoor air during unoccupied times. The building water use is more than 30% better than code compliance. Water-saving measures include the installation of water-efficient fixtures, rainwater harvesting, bioswales and native plantings. Through these measures, the lab has also reduced the amount of stormwater runoff at the property. In addition to the ongoing energy and water savings, more than 97% of construction waste was diverted from landfill throughout the project. National Univ. of Ireland, Galway Biosciences Research Building, Galway, Ireland The second Project Award was presented to the National Univ. of Ireland, Galway, Biosciences Research Building (BRB), a research lab for regenerative medicine, chem-bio and cancer. The BRB represents a “minimum energy” approach. Through careful planning and high-/low-energy zoning, the BRB integrates traditional building techniques with innovative energy-conservation solutions, resulting in an energy savings of about 70% annually against a baseline of comparable projects. The high-/low-energy zoning strategy wraps the perimeter of the building with the lowest energy use spaces, allowing for maximum daylighting and natural ventilation, while the high-energy use spaces are zoned within the “thermal sweater” of the lower use spaces, using a double wall system to separate ventilation systems and optimizing building-wide energy use. The 2015 Go Beyond Award winners can also be found on I2SL’s Website at www.i2sl.org/conference/2015/awards.html. I2SL plans to hold the Go Beyond Awards again in 2016. A call for nominations will be sent in summer 2016 and awards will be presented at the 2016 I2SL Annual Conference, taking place September 25 through 27 in Kansas City, Mis.

Light detection and ranging—i.e., LiDAR, a method that uses pulsed laser light—relies on 3D laser scanners. These scanners are used in a large variety of manned and autonomous applications that require real-time 3D-perception sensors for obstacle detection and avoidance. 3D laser scanners that can operate in harsh environments and conditions with poor visibility are particularly desirable. For example, one application for such a device could augment the situational awareness of helicopter pilots as they land in unprepared terrain, where the downwash of the rotors can cause poor visibility by stirring dust, sand, or snow on the ground.1, 2 In addition to penetrating obscurants, such a scanner would ideally be capable of achieving a high enough resolution to enable the detection of small objects that could cause damage to a helicopter, such as wires, metal rods, and fence posts. It is equally important for such a LiDAR system to cover a large field of view (FOV). These requirements are difficult to implement in a single compact system. For example, in one existing approach, a LiDAR is mounted on mechanical gimbals to steer a small field of view in different directions. However, this approach adds weight, volume, complexity, and cost to the system. It also introduces additional uncertainties that arise as a result of errors in the angular positions of the gimbals. Our work seeks to overcome these issues, and to meet the demands for a robust LiDAR system. We have therefore developed a unique and innovative approach based on the use of compact optical components in which a small-FOV scan pattern can be steered within a larger field of regard (FOR). For this purpose, Neptec has developed 3D laser scanners (i.e., OPAL) that can penetrate dense obscurant conditions considerably better than the naked eye. The OPAL scanner uses Risley prism-pair technology, where two superimposed prisms are independently rotated by hollow shaft motors. A laser pulse traveling through the hollow shaft motors is bent by the rotating prisms to form a scan pattern that comprises several rosettes. This implementation offers a number of advantages, including a multitude of possible scan patterns, rapid generation of non-overlapping patterns, and a conical FOV with very high data density around its center. The geometric and material properties of the prisms define the conical FOV of the LiDAR, which can typically be set between 30 and 120°. Ideally, the operator of such a system would be able obtain very high data density at a particular location, with the additional flexibility of being able to quickly move this high-density FOV to another area within the FOR. As the result of a collaboration between Neptec and Defence Research and Development Canada, we have together developed a unique scanner prototype using double pairs of Risley prisms3 that achieves this aim. The first prism pair generates a 30° FOV, which may then be steered within a larger 90° FOR by employing the second pair of prisms. This setup has the advantage of a high-resolution scan-pattern footprint that can be moved quickly and randomly within a larger area, thereby eliminating the need for mechanical steering equipment. Moreover, the FOR is not limited to 90° and can be extended to something on the order of 120°. An illustration of this arrangement is shown in Figure 1(a), and a photo of our double Risley pair (DRP) scanner prototype is shown in Figure 1(b). In terms of its operational capabilities, our DRP can be used aboard an aircraft for a range of operations. For example, the system can scan a landing zone with high-resolution information, thereby increasing the chance of detecting small threatening obstacles (e.g., posts or wires). The system also offers a station-keeping capability, where the aircraft motions are compensated by the steering mechanism to keep the LiDAR FOV locked on an area of interest. The DRP could also be employed for tracking a small moving object in the FOR. Additionally, it could be moved by an operator to steer the high-resolution FOV to chosen locations, or over random spots by a computer program. Figure 2(a) shows LiDAR data obtained with our DRP prototype. In this application, the small 30° FOV is moved horizontally across the larger 90° FOR. The two sectors shown in Figure 2(b) correspond to the high-density FOV being steered to scan locations on either side of the overall FOR. The resulting data is color-coded to show the elevation of objects in the scene, where red- and blue-colored areas correspond to objects at lower and higher elevations, respectively. In summary, we have produced a compact LiDAR that is capable of steering a small, high-resolution FOV within a larger FOR, without the need for additional heavy and costly mechanical systems. As part of our on-going efforts, we will test our prototype aboard aircraft to determine its performance in poor visibility (i.e., caused by dust and snow).

Efforts have been devoted to the identification of the impacts of occupant behavior on building energy consumption. Various factors influence building energy consumption at the same time, leading to the lack of precision when identifying the individual effects of occupant behavior. This paper reports the development of a new methodology for examining the influences of occupant behavior on building energy consumption; the method is based on a basic data mining technique (cluster analysis). To deal with data inconsistencies, min-max normalization is performed as a data preprocessing step before clustering. Grey relational grades, a measure of relevancy between two factors, are used as weighted coefficients of different attributes in cluster analysis. To demonstrate the applicability of the proposed method, the method was applied to a set of residential buildings' measurement data. The results show that the method facilitates the evaluation of building energy-saving potential by improving the behavior of building occupants, and provides multifaceted insights into building energy end-use patterns associated with the occupant behavior. The results obtained could help prioritize efforts at modification of occupant behavior in order to reduce building energy consumption, and help improve modeling of occupant behavior in numerical simulation. © 2011 Elsevier B.V.

Energy retrofit measures (ERMs) are applied to reduce the energy consumption of buildings. The effectiveness of any ERM depends on many building specific factors, such as location, size, operation, building envelope, electrical, heating, cooling and ventilation system properties. It is common for multiple ERMs to be applied to a building to reduce its energy consumption. However, the reduction in energy consumption when multiple ERMs are applied is not the sum of the impact of individual ERMs. Effectiveness of multiple ERMs depends upon their interactive effects. Using representative office buildings and an energy modelling computer program, the effectiveness of individual and multiple ERM was assessed providing a better understanding of their interactive effects. © 2011 Elsevier Ltd.

There is a growing interest in integrated control strategies for building systems with numerous responsive elements, such as solar shading devices, thermal storage and hybrid ventilation systems, both for energy efficiency and for demand response. Model predictive control is a promising way of approaching this challenge. This paper presents a flexible software framework for model predictive control using GenOpt, along with a modified genetic algorithm developed for use within it, and applies it to a case study of demand response by zone temperature ramping in an office space. Various areas for further research and development using this framework are discussed. © 2010 Elsevier B.V.

A Single-Degree-of-Freedom (SDOF) model is used to determine the effect of axial load on column strength and stability during a blast event. The model, which accounts for the axial load-bending interaction (P-δ effect) and strain rate effect on the column dynamic response, is validated by comparing its results with experimental data from blast tests on full scale steel columns and with the results of the finite element software LS-DYNA. Maximum displacements and moments obtained from SDOF analysis are also compared with the results of the interaction formulas recommended by the Unified Facilities Criteria (UFC 3-340-02) design manual for steel structures. It is shown that the UFC method overestimates the column capacity for ductility ratios μ greater than one, irrespective of the axial load to Euler elastic buckling load ratio (P/P e). Also for P/Pe > 0.5, even if μ < 1.0, the UFC method still overestimates the actual column capacity. For dealing with this problem in practical applications, non-dimensional beam column curves are developed to include the effects of the blast load and column properties on both its strength and stability. © 2012 Elsevier Ltd.

The re-centering phenomenon of superelastic Shape Memory Alloy (SMA) reinforced concrete is a unique characteristic that is appealing for structural applications, along with the ability to respond with stable hystereses and achieve similar strength and ductility to concrete reinforced with conventional deformed bars. The objective of this study was to investigate the structural performance of superelastic SMA reinforced concrete and to develop a preliminary constitutive model applicable to nonlinear finite element algorithms. Seven simply supported flexure-critical concrete beams, reinforced with either SMA bars in the critical region or conventional deformed reinforcement, were subjected to monotonic, cyclic, and reverse cyclic loading. The experiment results demonstrated the superior capacity of the SMA beams to recover inelastic displacements. The SMA beams sustained displacement ductility and strength capacity comparable to the conventional beams. Crack widths and crack spacing were larger in the SMA beams; however, upon removal of load, the crack openings were recovered. Energy dissipation was lower in the SMA beams, particularly when subjected to reverse cyclic loading. The constitutive model based on a trilinear backbone envelope response and linear unloading and reloading rules provided satisfactory simulations. © 2013 Elsevier Ltd.

Private and public sectors own and operate an array of office buildings that consume energy and contribute to the emission of greenhouse gases (GHG). Energy demands can be reduced by applying energy retrofit measures (ERMs) to existing buildings. The choice of ERMs involves evaluation of applicability, energy end uses and cost of application versus energy savings. This paper describes a methodology developed to screen office buildings for their current level of energy consumption and potential for retrofit application. Selection of an optimal set of ERMs is influenced by climate, occupancy, heating and cooling systems, envelope properties and building geometry. When assessing the implications of applying ERMs to a large building stock it is vital to screen the complete building set for optimal retrofit opportunities. This can be accomplished by characterizing office building stock into a manageable set of archetypes and simulating building operation using energy simulation software. Using regression analyses, a model was developed for estimating the energy consumption. Present value analysis was used to optimize the evaluation of the various ERMs. The methodology developed can be used to simplify the ranking of buildings for retrofit; to select and combine ERMs, and to plan energy and GHG reduction activities. © 2010 Elsevier B.V.

The Government of Canada believes in protecting our natural environment while continuing to support vital infrastructure projects that ensure a vibrant future for Canada's middle class. During the environmental assessment of the new Champlain Bridge Corridor project, the Government of Canada committed to implementing projects that will compensate for the loss of natural habitats caused by the work. Therefore the government intends to invest over $10 million in the creation of spawning grounds for fish in the Rapides de Vaudreuil area between the Taschereau Bridge and Île aux Pins. The project will involve the creation of a 10-hectare area of spawning grounds for yellow walleye, lake sturgeon, smallmouth bass and a number of other fish species. This stable and sustainable development will be implemented along precise parameters of water depth and current speed in order to optimize spawning conditions in the Rapides de Vaudreuil area. Infrastructure Canada has worked closely with the City of Vaudreuil-Dorion, Fisheries and Oceans Canada, and Public Works and Government Services Canada to develop this compensation project which, in addition to providing numerous environmental benefits, will improve fishing conditions in the area of the Rapides de Vaudreuil. "The Rapides de Vaudreuil spawning grounds project reflects how the Government of Canada, by working closely with the local community, key stakeholders and its various partners, is building the new Champlain Bridge quickly and sustainably, while protecting and preserving our natural environment. The Government of Canada is committed to establishing solid partnerships with all orders of government to support infrastructure development and create good, well-paying jobs to help the middle class grow and prosper today." The Honourable Amarjeet Sohi, Minister of Infrastructure and Communities "When completed, this major project will benefit the citizens of Vaudreuil-Dorion by enhancing the opportunities for recreational fishing through improvements to the aquatic ecosystem in the area of the Rapides de Vaudreuil."
