Solar by Taitem – the Viridius Story

Ithaca property rental company Viridius turns to Taitem for a solar energy solution to grow the business bottom line and achieve their sustainability mission of Earth Friendly Rentals. Owners Zöe Hare and Stuart Staniford describe the process and why they chose local solar installer Taitem Engineering. Stunning aerial views of their Snyder Hill property show the 21.5 kW ground-mount photovoltaic array. State-of-the-art technology for design and data collection, paired with Taitem’s accessible community presence, are key benefits for Viridius. Tenant Michael Lenetsky couldn’t be happier.

Support Team Taitem’s Ride for Life – Sept. 9

The Southern Tier AIDS Program does incredible work to prevent the spread of HIV and provide care management services for HIV+ individuals.  Taitem is again a Corporate Sponsor for the 19th annual Ride for Life around Cayuga Lake on Sept. 9.  Please join us in supporting this essential community organization by donating to our team’s fundraising goal of $7,200 and/or volunteering on Ride day.

Taitem recently toured the Ithaca office of STAP. We learned that almost 100 staff members in 3 offices serve clients and run programs in 8 counties. Because HIV often spreads intravenously, STAP has become a leader on the front lines of the opioid epidemic. For instance, the Syringe Exchange Program reduces harm to users of both legal and illegal drugs and stops the spread of many diseases, including Hepatitis C. We saw the big machine that sterilizes the used sharps and chops them into little bits before they are properly disposed of as non-hazardous waste.

We also saw how a Narcan kit works to deliver the antidote naloxone if someone has overdosed. STAP distributed 2,000 Narcan kits in 2016! There were 310 overdose reversals reported as a result.  More impressive stats:

As engineers we appreciate numbers. As people, we appreciate the warmth, compassion and commitment so clearly expressed by the staff we met during our tour. We hope you will make a donationvolunteer and hold the clients, staff and community of STAP in your heart.

USGBC Tour Features Zero Energy Hemsin House

Hemsin House
Zero Energy home in Ithaca NY

For architects, building professionals and anyone who wants to learn what it takes to create affordable homes and a net zero energy footprint, this event at the newly-completed Hemsin House in Ithaca will be educational and inspiring. On Wednesday, July 12, the New York Upstate Chapter of the US Green Building Council will host a tour and presentation by owner-designers Courtney Royal and Umit Sirt, both sustainability professionals at Taitem Engineering. Event details and registration.

Hemsin House, on a hilltop overlooking Cayuga Lake, is a cost-effective, healthy home for the couple and their two young children while also serving as a sustainability showcase. Solar panels on the roof generate enough electricity to heat, cool, and power all appliances and lighting in the course of a year, and help the house earn the Energy Star and LEED Zero Energy designations. A 15% window-to-wall ratio, optimitized building envelope design, use of local hardwoods, water conservation methods, low VOC paint and finish materials, and even landscaping will help the home attain LEED for Homes Platinum status.

Tour attendees can earn continuing education credits: 1.5 LU  from the American Institute of Architects and 1.5 hours from the Green Building Council Institute.

Taitem now helps clients achieve LEED Green Homes distinction

Taitem is proud to announce that Senior Sustainability Consultant Courtney Royal has been named a LEED for Homes Green Rater. She is one of only six accredited professionals serving upstate New York with a local presence. Courtney works with homeowners and multifamily developers to create beautiful green buildings that minimize operating costs, while earning national recognition from the US Green Building Council.

LEED stands for Leadership in Energy and Environmental Design. The LEED for Homes and LEED for Multifamily Midrise certifications guide building owners to achieve environmental and financial goals. As a Green Rater for Taitem Engineering, Courtney Royal consults and provides technical support for new construction and major renovations of existing homes and multifamily dwellings up to eight stories tall.

Q: Why engage a Green Rater for a home or multifamily building?

A: Because Green Raters help:

  • Build for durability and sustainability
  • Improve the environment and your bottom line
  • Lower utility bills by avoiding energy waste
  • Support good health and beautiful aesthetics with natural materials, intentional daylighting, and clean indoor air.
  • Comply with local laws that require LEED certification (in certain locations)
  • Earn Energy Star certification then take it up a notch. Achieving a LEED Green Home rating satisfies the Energy Star requirements while also addressing water use, site impacts, building materials, and more.
  • Qualify for property tax abatements (in certain locations)

Taitem is responsible for on-site verification and works with the owner’s project team to complete the LEED for Homes Workbook certification packet. Courtney is involved from the design phase through construction completion to ensure sustainable features are incorporated and project certification targets are achieved.

Walking her talk
Courtney’s most recent project is her own home, completed in December 2016 on a hilltop overlooking Cayuga Lake. The house, collaboratively designed with her engineer husband Umit Sirt (also of Taitem), is slated to earn both the LEED for Homes Platinum and Zero Energy Capable designations. A few of its many notable features include:

  • Light-filled interior created with a low 15% Window to Wall Ratio (WWR); wedged walls surround all windows and highly reflective paints and surfaces enhance the space.
  • Gorgeous compressed-paper countertops with the look and feel of stone
  • Heat pumps for clothes drying, domestic hot water, and of course heating and cooling.
  • Stormwater management using grassed swales to feed an on-site pond

How do I learn more?
Schedule a complimentary consultation with Courtney. Expect her to ask great questions, listen for your goals, and clarify which building features matter most to you, including the look and feel of your renovated or future home. She will describe her process of working with the architect, contractor and entire team, and the benefits you can expect as a result.

Eliminating Energy Use in Existing Buildings: Easier Than We Think?

Check out this snippet from a recent post @Building Evidence:

…the focus of a talk on existing buildings raised a few eyebrows and people have been coming to ask:  Can it possibly be easy to eliminate energy use in existing buildings? Here is a summary of the talk:

  • Climate change is real. The widely-accepted goals of reducing carbon emissions by 80% by 2050 are important.  2050 is not far off. We need to get moving. And the task at hand may be … easier than we think. READ THE FULL POST….
