挑战
In extreme climates, moisture and temperature changes can damage building foundations. Vahanen Group, a company specializing in building services, analyzes the potential for frost damage in buildings being considered for renovation. Their work is especially vital in cases where renovations are necessary due to existing damage, such as when heating systems and pipes need to be replaced. The challenge is to determine whether certain renovations to foundations or heating systems would require adding external frost insulation, which, if added unnecessarily, would waste valuable money, time, and work.
关于客户
Vahanen Group, based in Espoo, Finland, is a company specializing in building services such as quality assessments and construction recommendations. They focus on analyzing the potential for frost damage in buildings being considered for renovation. Their work is crucial in ensuring the safety and longevity of building structures, especially in extreme climates where moisture and temperature changes can cause significant damage. Vahanen Group uses advanced simulation tools to provide construction teams with accurate assessments and recommendations, helping to prevent structural damage and maintain safe building environments.
解决方案
Pauli Sekki, a building specialist at Vahanen, uses the simulation capabilities of COMSOL Multiphysics to perform risk assessments. His goal is to discern whether certain renovations to foundations or heating systems would require adding external frost insulation. For one project, Sekki's COMSOL model includes the foundation, levels of loose soil and packed earth, several types of insulation, lightweight concrete walls, and a pipe from a heating system passing underneath a building near the wall and foundation. Sekki simulated temperature changes based on local climate data for Helsinki, Finland, and generated a 'critical freezing' quantity to account for abnormally cold winters. This simulation helps determine whether renovations, such as the complete removal of a damaged heating pipe, would endanger the building. The tools in COMSOL Multiphysics are very easy to use for this kind of complex model, providing almost unlimited possibilities for setting boundary conditions.

Energy Saving & Power Monitoring System
Recently a university in Taiwan was experiencing dramatic power usage increases due to its growing number of campus buildings and students. Aiming to analyze their power consumption and increase their power efficiency across 52 buildings, the university wanted to build a power management system utilizing web-based hardware and software. With these goals in mind, they contacted Advantech to help them develop their system and provide them with the means to save energy in the years to come.

IoT System for Tunnel Construction
The Zenitaka Corporation ('Zenitaka') has two major business areas: its architectural business focuses on structures such as government buildings, office buildings, and commercial facilities, while its civil engineering business is targeted at structures such as tunnels, bridges and dams. Within these areas, there presented two issues that have always persisted in regard to the construction of mountain tunnels. These issues are 'improving safety" and "reducing energy consumption". Mountain tunnels construction requires a massive amount of electricity. This is because there are many kinds of electrical equipment being used day and night, including construction machinery, construction lighting, and ventilating fan. Despite this, the amount of power consumption is generally not tightly managed. In many cases, the exact amount of power consumption is only ascertained when the bill from the power company becomes available. Sometimes, corporations install demand-monitoring equipment to help curb the maximum power demanded. However, even in these cases, the devices only allow the total volume of power consumption to be ascertained, or they may issue warnings to prevent the contracted volume of power from being exceeded. In order to tackle the issue of reducing power consumption, it was first necessary to obtain an accurate breakdown of how much power was being used in each particular area. In other words, we needed to be able to visualize the amount of power being consumed. Safety, was also not being managed very rigorously. Even now, tunnel construction sites often use a 'name label' system for managing entry into the work site. Specifically, red labels with white reverse sides that bear the workers' names on both sides are displayed at the tunnel work site entrance. The workers themselves then flip the name label to the appropriate side when entering or exiting from the work site to indicate whether or not they are working inside the tunnel at any given time. If a worker forgets to flip his or her name label when entering or exiting from the tunnel, management cannot be performed effectively. In order to tackle the challenges mentioned above, Zenitaka decided to build a system that could improve the safety of tunnel construction as well as reduce the amount of power consumed. In other words, this new system would facilitate a clear picture of which workers were working in each location at the mountain tunnel construction site, as well as which processes were being carried out at those respective locations at any given time. The system would maintain the safety of all workers while also carefully controlling the electrical equipment to reduce unnecessary power consumption. Having decided on the concept, our next concern was whether there existed any kind of robust hardware that would not break down at the construction work site, that could move freely in response to changes in the working environment, and that could accurately detect workers and vehicles using radio frequency identification (RFID). Given that this system would involve many components that were new to Zenitaka, we decided to enlist the cooperation of E.I.Sol Co., Ltd. ('E.I.Sol') as our joint development partner, as they had provided us with a highly practical proposal.

Intelligent Building Automation System and Energy Saving Solution
One of the most difficult problems facing the world is conserving energy in buildings. However, it is not easy to have a cost-effective solution to reduce energy usage in a building. One solution for saving energy is to implement an intelligent building automation system (BAS) which can be controlled according to its schedule. In Indonesia a large university with a five floor building and 22 classrooms wanted to save the amount of energy being used.

Splunk Partnership Ties Together Big Data & IoT Services
Splunk was faced with the need to meet emerging customer demands for interfacing IoT projects to its suite of services. The company required an IoT partner that would be able to easily and quickly integrate with its Splunk Enterprise platform, rather than allocating development resources and time to building out an IoT interface and application platform.
