Energy consumption of HVAC system play a big role on the whole building energy usage. Recommissioning on HVAC system can improve build comfort and its performance. Taking the recommissioning of public office as an example, the issue of the energy consumption of HVAC system was found, control scheme of chilled and hot water system and AHUs was optimized, the new energy saving control scheme was determined, and the actual energy consumption was analysed. The result show that recommissioning for the public office building achieved obviously effect, and the rate of energy saving is 18%, 33% and 10% for chilled water, hot water and electricity, respectively.

<p>During the last decade a lot of attention has been paid to sustainability of structures. Reuse of existing buildings, limiting environmental impact and reuse of elements were applied in practice. In general, reuse of elements, with for instance the use of a donor skeleton, was applied on a very limited scale, as this reuse often comes at a price. In 2018 there was an opportunity to apply a donor skeleton on a larger scale in an office building of 6200 m2. This paper will describe the process of design and construction of this special project, and will derive lessons learned in order to increase application of upscaling of building elements in future projects.</p>

ABSTRACT Facility Manager (FM) role requires expertise in various aspects of facility maintenance. Due to the diverse job functions as an FM, outsourcing and hiring external vendors is a common practice in the industry to gain additional expertise. Since a facility manager oversees the external vendor's contract and the performance of the external vendor directly affects the quality of a facility, the FM's performance is ultimately related to the performance of the outsourcing company. Hence, it is critical to measure performance and the quality of the services provided by the outsourcing company. One of the FM's at a corporation (XYZ Corporation) was faced with a challenge of low performance and poor quality on their outsourced janitorial contract. The literature review revealed that there has been very little research done with regard to outsourcing of the janitorial contract. In order to address the challenge of XYZ Corporation a performance measurement model was implemented using performance Scorecards at XYZ Corporation for janitorial contracts. The Scorecard was developed based on the previous experience of the FM group, the researchers and the specific areas targeted by XYZ Corporation that were part of janitorial vendors responsibility. This paper presents the impact of the performance measurement model on the quality and performance of the janitorial vendor and its expansion to other outsourcing contractors based on the lessons learned from the janitorial contracts. The study revealed that the implementation of a performance measurement model resulted in an overall improvement of the performance of janitorial vendor and the contractors.

Control Procedures

Measurement and verification (M&V) has become necessary for ensuring intended design performance. Currently, M&V procedures and calculation methods exist for the assessment of Energy Conservation Measures (ECM) for existing buildings, with a focus on reliable baseline model creation and savings estimation, as well as for reducing the computation time, uncertainties, and M&V costs. There is limited application of rigorous M&V procedures in the design, delivery and operation of low/zero energy dwellings and settlements. In the present paper, M&V for four pilot net-zero energy settlements has been designed and implemented. The M&V has been planned, incorporating guidance from existing protocols, linked to the project development phases, and populated with lessons learned through implementation. The resulting framework demonstrates that M&V is not strictly linked to the operational phase of a project but is rather an integral part of the project management and development. Under this scope, M&V is an integrated, iterative process that is accompanied by quality control in every step. Quality control is a significant component of the M&V, and the proposed quality control procedures can support the preparation and implementation of automated M&V. The proposed framework can be useful to project managers for integrating M&V into the project management and development process and explicitly aligning it with the rest of the design and construction procedures.

This case highlights a recent and important type of new sustainability project for existing buildings commonly referred to as an integrated energy retrofit (IER) project. Anthony Malkin of Malkin Holdings, owner of the Empire State Building (ESB), acknowledged the importance of making the existing building stock, particularly in New York City, more energy efficient, as it comprises a large part of the real estate in most cities. Taking a bold leadership position, Malkin vowed to make the ESB the most energy-efficient, sustainable, “green” pre-war office building through an IER project that examined several facets of the building's systems, operations, and tenant behaviors. In addition to making the ESB a green icon in Manhattan, Malkin also stated the importance of making the project transparent and economical so other pre-war buildings could copy the model. This case study examines in depth the process that Malkin Holdings underwent in attaining its goal of establishing the ESB as a leader in existing building sustainability.After discussing and analyzing the case, students should be able to: Understand how to balance costs and benefits associated with an IER project Explain the benefits of green retrofitting to owners and tenants Identify risks in high-profile, complex projects and recommend mitigation strategies

Office buildings constitute a significant proportion of the non-residential building stock. In recent years, various rating tools have been developed to foster green office building development. The Green Building Council of Australia (GBCA) has developed the Green Star - Office rating tools for this purpose. There are an increasing number of stakeholders adopting these tools to showcase their efforts in sustainable development. This research focuses on the challenges and barriers in obtaining GBCA ratings in Australian Office buildings. To accomplish this, the scoring sheets from the rating of 264 certified office buildings were collected and critically analysed. The findings indicated that credits related to the attributes of innovation, ecology and energy are comparatively difficult to achieve. It was also found in this study that a large number of projects did not apply for the specific credits of refrigerant global warming potential, re-use of façade, topsoil and fill removal from site, and individual comfort control. This study provides a useful reference to both the property developer and the Green Building Council of Australia for green building developments in the future. In particular, the findings provide useful inputs to the development of the next generation of green building rating tools.
