Many building owners are suspicious of energy performance contractors because the performance contractor is both a player and a score keeper. Because a significant effort is required to understand the information in building systems, there are significant start-up costs. These costs, both in money and time, require that each contract include a significant minimum contract lengths over which to amortize the up-front costs. These up-front costs make it uneconomical for energy contracting to use a third party auditor to verify results.If the owner selects a new a new performance contractor, the up-front costs will be incurred again.

Slim BIM: The Middle Ground between Document and Service Part 2
In my last post, introduced Slim BIM and the critical need for shared configuration to speed development in the building systems. This post extends that conversation.
A report from NREL, delivered last Spring, defined the Building Service Interface (BSI), a standard for interacting with building systems from non-building applications. That report recommended that each BSI be able to share a light-weight BIM, i.e., ...
Big Data, Buildings, and the Internet of Things
Big Data is the hot new buzz-phrase for something that buildings system integrators have long struggled with. Last Thursday (3/29), the White House Office of Science and Technology Policy (OSTP) launched its public initiative on big data for government, the Big Data Research and Development Initiative.
The purpose of big data is to support analytics, that is the massive...
BSI Part 1: What is the Building System Interface?
After the ASHRAE meetings, and during the AHR conference, several of us are getting together to discuss building system metadata. The goal is to define interfaces to support quick fast integrations of building systems into the wider world. This is the first of several posts describing this interface. Drop me a line or watch for announcements from LONmark if you want to join us for discussion.
In my smart grid work, I began describing each end node as a microgrid. A microgrid is a self-contained entity responsible for managing its own energy use, generation, storage, conversion, and as a last resort, market operations. This model eliminates...
