Managing energy demand can be beneficial for both the energy consumer and the energy supplier. By reducing energy use, the consumer reduces operating costs and improves production efficiency and competitiveness. Similarly, the supplier may reduce the need for costly capacity expansion and wholesale power purchasing, especially if energy reductions occur during peak lo....

This paper discusses the specific concept for, design of, and results from a pilot program to automate demand response with critical peak pricing. California utilities have been exploring the use of critical peak pricing (CPP) to help reduce peak day summer time electric loads. CPP is a form of price-responsive demand response. This Automated Critical Peak Pricing (A....

Single duct variable air volume (VAV) systems are widely used in office buildings to achieve energy savings. It supplies proper amount of conditioned air to satisfy both the load and the ventilation requirements of each individual zone. To obtain acceptable indoor air quality (IAQ), the overall outside air (OA) intake ratio has to consider the demands from all the zones....

Building structure thermal storage (BSTS) HVAC systems can store heat during nighttime thermal storage operation (nighttime operation hours) by using off-peak electricity and release it in the daytime air-conditioning operation (daytime operation hours) by utilizing a large amount of the thermal capacity of building structures such as beams, columns and floors composed ....

A model co-relating the peak load demand of a utility with the allowable power rating (PR) of air-conditioning (AC) systems has been developed in this paper through a well defined methodology. The model is capable to predict the extent of allowable increase in the capital cost of the AC system for an improvement in PR from its base case as well. Furthermore, effective....

In office buildings there are generally two HVAC systems installed, one in the perimeter zone (PZ) and one in the interior zone (IZ), and the temperatures of each zone are independently controlled. In the present paper, in order to the solve problem of not being able to satisfy the requirements of room temperature control during the cooling period in summer, an optimal ....

This paper demonstrates the implementation of new innovative technologies during continuous commissioning (CC®) practices to improve building operations and reduce energy costs. The case study building is a 5-story office facility with total floor area of 91,200 square feet, most of which is open space. An energy audit was conducted to evaluate the building's energy pe....

Commercial kitchens usually require a large amount of ventilation air and high ventilation rates. Today's typical kitchens and dining facilities are often equipped with Make-up Air Fans (MAF) or dedicated Make-up Air Units (MUA) to make up about 50% to 80% of the total exhaust air through range hoods. Comparing with 8:00 am to 5:00 pm operation of general office buildi....

Continuous Commissioning® (CC®) of the Reynolds Army Community Hospital facility was a two phase project. The first phase consisted of a point-to-point verification of a newly upgraded Energy Management Control System (EMCS) and calibration of key sensors that would have a significant impact on control system operations. The second phase was the implementation of CC....

This paper presents a case study for Continuous Commissioning® (CC®)of a 520,000 square foot medical research facility. All of the primary energy using systems in the building were investigated to determine their existing condition and operation. Using these findings, the needed CC® measures were developed. Some of the CC® measures include repairing the heat exch....

Boilers account for about 42% of space heating energy consumption in commercial and multifamily buildings in the U.S. Boilers are typically designed to be oversized, with redundant safety factors and without consideration of internal heat gains. Significant energy savings could be achieved by optimizing the selection of commercial boiler systems and utilizing proper ope....
