Today’s presentation addresses: • What is a High Performance Building (HPB)? • What are the benefits of HPBs? • What are the barriers to creating HPBs? • What are the elements of a process that will deliver a HPB? MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
A high performance building serves the needs of the people who inhabit it. It supports and nurtures their health, satisfaction, productivity, and spirit. It connects them to the natural world and the place they inhabit. An elegant architectural integration of high performance building strategies creates a building that honors the aspirations of those who use it, and engages the natural world. In its highest form, a high performance project is restorative and regenerative of its place in the world. MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.

Benefits of HP Buildings • Human health, performance, satisfaction - Faculty/student/staff attraction and retention • Cost savings – energy, maintenance, capital, infrastructure, employee retention • Image and self-image • Unparalleled educational opportunities across disciplines MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
What’s The Catch? To create a high performance building that provides these benefits, a design approach is needed that integrates all of the players from the beginning, and this design process must be as carefully designed as the building.

What Are The Barriers? • The perceived barriers are: • Cost • Time • Risk • The actual barriers are: • Knowledge Base • Mindset MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Is Cost Really a Barrier? The bad news: You can’t add something into a project without taking something else out. The good news: There’s stuff to take out! And… Better doesn’t always cost more My own bottom line is that no client ever told me I had extra money allocated in the budget to make a building green.

Cost Case Studies Harvard Law School Whittemore Hall MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Lifecycle Cost • Be sure to analyze costs beyond first cost, including energy costs, maintenance costs, and repair/replacement costs. MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Time • Integrated design is front-loaded – time is needed to fully understand the site and the program, and then the unique opportunities • Some of this time is made up later when there are fewer co-ordination snafus, a shorter and less destructive cost-cutting phase, and fewer change orders during construction. MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Risk • When you ask people to do something they haven’t done before, you increase risk. • Risk must be clarified and people’s fears must be fully heard. • Research may need to be done to progress. • Document assumptions and decisions. • Identify the risk of doing the status quo. • The Owner makes the ultimate decision of how much risk is acceptable. MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Knowledge Base • High performance design and integrated design process are rarely taught or practiced • Basic building physics – how heat, air, and moisture act in buildings – is rarely taught • User feedback and building performance data rarely gets back to design professionals • Most design professionals are not current • There’s a lot of dogma and myth out there! MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Mindset • The largest single barrier to creating high performance buildings that delight their users and regenerate their surroundings is simply MINDSET. • I’ve heard that doesn’t work, we’ve never done it that way, we’ve always done it that way, it won’t be beautiful, it’s too risky, it will be too expensive, no one will bid on it….. MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
So is this really possible to achieve? Yes! MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Will Using LEEDTM Assure Success? • Nope. It’s a good tool, but a checklist will never guarantee that integrated design will occur. • LEED Accreditation of design professionals is easy to obtain and guarantees nothing. MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Find the Right Team • Use behavioral interviewing techniques and focus on past performance • Seek hard evidence that the team has done what they claim – look at design process minutes, construction documents, resource use data on projects, speak with maintenance staff and users • Interview engineers as well as architects MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Set Goals and Measurable Objectives • Build a shared vision among all the stakeholders • Set prioritized goals, then measurable objectives MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Insist on a Integrated Design Process • Make certain the engineers are present at the conceptual stage • Begin with a charrette and schedule periodic, focused work sessions with the entire team • Task design professionals with clearly presenting trade-offs on key decisions • Assign responsibilities and delivery dates • Draw the analysis box and cost box large enough MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Manage Risk • Identify risks of both unfamiliar and familiar approaches. • Identify information needed to make a fully informed decision – seek previous implementations of proposed strategies – anything that exists is possible MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
And then… • Build it right • Create feedback loops for users, designers and operators • Evaluate what worked and what needs improvement • Publicize successes and MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
Make lasting buildings that regenerate the places they inhabit, nurture their users, honor the web of life, and expand the human vision of what is possible MHEC High Performance Buildings - 5/30/2003 - Marc Rosenbaum, P.E.
