Sun/Shade & Urban Development – October 2015

What are your thoughts about shadowing from proposed buildings?

Sections of Surfers Paradise will remain in darkness after dawn because of shadowing from the planned Iluka supertower, says a technical report.

The proposed 88-storey tower will cast a shadow not just on the beach but across the other accommodation buildings just south of the site along The Esplanade.

A peer review by the sustainable design and development group Greensphere Consulting on behalf of residents challenges the work conducted by specialists working for the Iluka developers…

Four 120-metre-plus towers may rise in Toronto's Entertainment District | via @buzzbuzzhome


A trio of proposed high-rise developments, including four towers, could significantly alter the skyline of Toronto’s Entertainment District…

For two of the projects, proposals from Graywood Developments and Carlyle Communities, applications have not been put through to the City. A third, from Humbold Properties Limited, is currently in the rezoning process.

Graywood’s pre-application proposal is for a mostly residential development with commercial tenants at street level at 102-118 Peter Street and 350-354 Adelaide Street West. It encompasses two towers for a combined total of about 900 units. The taller tower would be roughly 50 storeys tall, or about 150 metres — just seven metres shy of the nearby TIFF building — while the shorter tower would be 39 storeys, or a height of about 120 metres…


The Carlyle Communities’ vision for 122-128 Peter Street and 357 Richmond Street West is a two-tone, 46-storey, 138-metre-tall tower...

Proposed Sixth Street Development Prompts Hearing On Shadow's Impact On SoMa Parks | @HoodlineSF

363 6th street

The Rec & Parks Commission is joining the Planning Commission at a special joint hearing Thursday to consider whether a proposed development at Sixth and Clara streets will have an adverse effect on Central SoMa's green spaces…

According to the Planning Department's assessment, the plans adhere to the guidelines set by the Eastern Neighborhoods Area Plan (which was approved by the Mayor and Board of Supervisors in December 2008) and will not result in significant environmental impacts beyond those already identified in the area plan's environmental review. Therefore, the project is not required to compile a project-specific environmental review.

However, given that the development is over 40 feet tall and could have the potential to cast new shadows on Gene Friend Recreation Center and Victoria Manalo Draves Park, the city was required to conduct a shadow analysis under Proposition K Sunlight Ordinance — which was approved by city voters in 1985 to protect public open spaces under Rec & Parks jurisdiction from negative impacts of development.

According to the shadow analysis conducted by CADP on behalf of the departments, the development would not cast any new shadows on Victoria Manalo Draves Park. Shadows resulting from the complex in the morning and evening would fall on areas already shadowed by surrounding buildings.

The analysis does find that the proposed Saturn Apartments would increase shadows on Gene Friend Recreation Center — which may receive a complete redesign in coming years — by .028 percent a year, but CADP predicts that the new shadow would subside before the park opens at 9am.

"The longest duration of new shadow would be approximately 22 minutes and the average shadow would be cast for less than 12 minutes," the report states. "All new shadow cast occurs before the park opens and is mostly projected on walkways, a small portion of the green field adjacent to the corner of Sixth Street and Folsom Street."…

Shadows over the CBD: have Melbourne's skyscrapers reached a tipping point? | The Age

"People will wake up in four, five or six years and say, 'Wow! What happened?"

In early 2013, Michael Buxton was pondering what central Melbourne was becoming. On every available site, yet another skyscraper was being either built or planned or spruiked. There was a deep, unsettling sense we were witnessing a city being transformed.

Buxton, a planning expert from RMIT, had not long before given the then planning minister Matthew Guy the moniker Mr Skyscraper. Catchy and contentious, the characterisation stuck, neatly capturing the minister's enthusiasm for buildings tall.

Is it too late for Melbourne? Has too much damage already been done?

Sixth & Clara Development Wins Planning Commission Approval, Shadows And All | via @HoodlineSF

The days are numbered for the 95-year-old industrial building at 363 Sixth St., as the Planning Commission has approved plans to construct a mixed-use apartment complex on the site.

Given that the 85-foot-tall building would cast a shadow on the nearby Gene Friend Recreation Center, the Planning and Rec and Parks commissions were first required to hold a special joint hearing to determine whether raising the park's shadow limit by .02 percent to allow the development to proceed would have an adverse affect on the center and its green space. While the two commissions voted 10 to 1 in favor of raising the shadow limit, the matter wasn't taken lightly.

The first major concern for the commissions was the number of developments that could also add shadows to Gene Friend and Victoria Manalo Draves Park in the near future. While presenting the prepared shadow analysis for 363 6th St., Planning Department staff noted that development plans are being drafted for at least four sites surrounding the two recreation spaces. Based on early-stage plans, three of those projects could add new shadows to at least one of the parks.

Another key issue: the idea of trading sunlight for other community benefits. While community members and commissioners widely applauded the project's developer, Realtex, for providing a laundry list of long-term benefits—including $185,000 in contributions to a variety of neighborhood recreation and youth programs, to be disbursed over the next five years—Rec and Parks Commissioner Eric McDonnell for urged his peers to strictly focus on the issue of the shadows.

“It feels like a slippery slope when we begin to add to the consideration how good the company is,” he said.

Part 3: The Architecture of Change | Opencity Projects

2015-10-25 17.03.48

At first glance, the proposed changes to the built environment in Mirvish Village are dizzying...

The proposed height of the tallest tower at Bloor and Bathurst is 29 storeys...

In planning land, it is conventional wisdom that pedestrians only engage with the first eight storeys of a building; whether 15 or 29 storeys, there is negligible impact on the pedestrian. But perhaps the main source of concern is the shadow impact on the adjacent neighbourhoods and businesses. To mitigate these effects, a typology common to Vancouver has been proposed: the micro tower. Micro towers are narrower than typical buildings erected in Toronto, having a smaller floor plate, thus casting narrower shadows…

Marymount School Unveils Rendering of 229-Foot Tower Planned for UES via @Dnainfo

 Marymount School unveiled a rendering of what its new building would look like.

The Marymount School for girls unveiled plans this week to construct a new state-of-the-art sustainable school building that will allow the school to consolidate its programs into one facility.

The 229-foot-tall building planned for 115 E. 97th St. will feature green terraces, gardens and possibly a solar panel system...

…the school will complete an environmental impact assessment before plans move forward, and that the school will follow the city regulations and have an open-door policy for those concerned about the work.

Jules Feinman, a resident and member of 97-98 Lexington & Park Ave. Neighbors, said he liked the project but was worried about the shadow the building would cast on the neighborhood. Currently, the lot is empty and is being used by the school as a tennis court.

"It is a really big building," Feinman said. "That air space is kind of everybody's solace and respite and the light is already blocked from 10:30 to 11:30 a.m. This is pretty much going to kill all morning light. I'm supportive but this is something you need to consider. We’re giving up a lot."…
