LEED for Homes Point by Point: Innovation & Design

Innovation & Design :: 9 points achieved out of 11 points available ::

We achieved 9 out of the 11 available points in this category. ID 1.3 Professional Credentialed with respect to LEED for Homes is apparently not available yet although we are using one (I believe this is in effect for applications made since mid-2009).  We also missed ID 1.5 which is building orientation for solar design because of the number of east facing windows (it faces Narragansett Bay and the Newport Bridge) – I make no excuses for our choice.

One of the most important aspects of ID is the quality management and durability planning. From the very beginning of our project, we created a Durability Checklist; we then used that as a working document to assign Scope of Works and as a checklist to make sure things were getting done as planned. Incorporated into our building contract, the checklist did evolve as the house was built taking into account any in field changes, additions or deletions.

The third portion is ID 3 which are Innovative Design – four points that are based on truly innovative or regional practices implemented on our project. We’ve been working on 3 of these points from the very beginning. The first point is Energy Management and involves the installation of a system that provides us as the homeowner’s automated control over various loads in the house. Having installed Control4 for home automation and Lutron for lighting control, our system is comprehensive, managing both individual loads and grouped system loads. The Control4 system controls the five-zone Geothermal HVAC system. We can access, control and manage any of the five zones from any of the access points in the house. Control4 includes pre programmed set scenes, timed programming, shutdown, individual temperature control and management of every zone.

The Control4 user interface has multiple options which includes ten touch screens located in each of the following rooms (front entry, kitchen (plus on wall tablet), guest room, children’s rooms (2), master bedroom, unfinished bonus room); remote controls in the living room, master and guest room, side table tablets in the master bedroom and on any PC in the house which includes the office. The interface displays information by the top eight monitored loads broken down to primary categories including: (1) lighting control system, (2) HVAC system, (3) entertainment system rack, (4) televisions, (5) kitchen refrigerator (6) pantry refrigerator (7) entertainment system rack, and (8) charging station. The energy management point takes into account al of the access and control from above and then measures how well the information is supplied to the homeowner. In our case, Control4 aggregates energy usage hour-by-hour, day-by-day, month-by-month. Information can be reported in graphs by time or by load. The system can also recognize and communicate areas of consumption that can be lowered to conserve energy and save money. These two points we won’t officially know the decision of the USGBC technical review committee for approximately another 90 days.

The third point we applied for was our “Wiring for a Green Home” plan, which saved us 52% of the materials used on a comparable project of size, scope and system requirements as determined by our electrical systems contractor. When we were told we’d have to wait 90 days to hear about the here open ID points, we said, well go ahead and submit anyway but what else can we do and we applied for 1.5 points for exemplary performance in MR 2.2 which was our use of environmentally preferred products.

The fourth ID point we applied for was for our high performance washing machine which required both an Energy Star rating and a water factor of 3.5 . Our Whirlpool Duet washing machine helped us achieve 1.5 points for reducing water usage by 74% and energy usage by 80% over washing machines manufactured before 2004. We also received one point for exemplary performance in Sustainable Sites (SS2.5) for attaining the full six points for our conservation and our irrigation system.
