Product News ecorcirc® hot water circulator


A state-of-the-art design allows the ecocirc to use 68 percent less energy than most standard pumps and can save an average family of four more than 12,000 gallons of water a year by eliminating the need to wait for the water to get hot. U s i n g only 10

Hydronic furnace


Hydronic furnace design works in con- junction with the Rinnai® tankless water heating system to efficiently heat the entire home, and features Electronically Commu t a t e d Motor (ECM) technology. This ultra-efficient brushless DC (direct current) motor operates up to 48 percent more efficiently than traditional PSC (permanent split capacitor) motors, which


translates into lower operating costs. Rinnai

It has been said that BIM usage


reduces risk in the project. How? • There are many ways that BIM


can reduce risk. We’ll mention just a few to start the conversation. • BIM is an integrated process that

vastly improves project understanding and allows for predictable outcomes. This visibility enables all project team members to stay coordinated, improve accuracy, reduce waste, and make informed decisions earlier in the process — helping to ensure the project’s success. • Using tools like the Revit BIM Portfolio and Navisworks risk is mitigated in many ways. Identifying clashes with Navisworks early on, means that you can identify errors, clashes and reduce expensive and time consuming RFIs, meaning you accept failing on the desktop and not in the field. It allows you to schedule work so that only the right personnel is on site, allows team to prefabricate MEP and reduce the number of site injuries. Using Conceptual Energy Analysis


features in Revit Architecture and Revit MEP means you can do earlier energy analysis and build a more sus- tainable design early on. • By using Revit and Navisworks models, visualizing the project


enables workers and owners know exactly what the project will look like (virtual fly throughs) and there is less risk of miscommunication, less chance of litigation. It is this accurate communication of design intent that delivers a huge benefit. What is the future of BIM? Any


new developments? Let me touch on two areas. First,


BIM has expanded beyond the focus of just buildings and now includes the civil engineering and infrastructure realm. The same principles that have improved the design and construction of buildings is now applicable for water, waste-water, power, smart grids and utilities, land development, road and highway projects. Second, the whole concept on considering the entire “building lifecycle” is now being rolled into BIM. Eighty percent of the cost of a building, over its life- time comes after the building is con- structed. This means the costs savings coming from electricity and water use, improved energy efficiency and main- tenance are significantly greater finan- cial considerations. High performance buildings are efficient buildings, delivering greater value to the owners and occupants. n
